Death of Armed Police in Nepal due to Blast of Computer

CRT Monitor Health Hazard
i am quite socked seeing the news about the blasting of computer leading to death of police officer at Birgunj, Nepal. especially CRT (Cathode Ray Tube) monitor operates at high voltage and is the energy reservoir. CRT system retains the high voltage energy for a long period of time even if it is shutdown. May be the following literature helps find out the cause of computer blast in Birgunj.

CRT Monitor Health Hazard
Have you ever walked across a carpeted floor and gotten a shock when you touched a doorknob, table, counter, or even another person? that little shock you got was a result of static electricity. It was also many times what is needed to destroy some computer components.
You see, humans can't feel a static shock until it is several thousand volts strong, but it takes less than 30 volts to damage a sensitive computer component, such as a stick of RAM or a processor.
That's why computer technicians and home computer builders have to guard their computers against the deadly ravages of static electricity, as well as take steps to avoid injury to yourself. A shock that you can't even feel can seriously damage your homebuilt computer before you're even finished building it.

Electromagnetics: Some believe the electromagnetic fields emitted by CRT monitors constitute a health danger to the functioning of living cells. Exposure to these fields diminishes by the inverse square law which describes the propagation of all electromagnetic radiation: double the distance, quarter the power. Likewise, the EM energy is also less intense for the display's user than for a person located behind it because the deflection yoke is behind the display's screen and therefore closer to the rear. It is well-known that electromagnetic waves of sufficient intensity can harm human cells (see ionizing radiation) but it is not currently well-established that the weaker radiation commonly emitted by electronic devices such as a CRT has long-term health effects (see Electromagnetic radiation hazard and Bio-electromagnetics).

Ionizing Radiation: CRTs also emit very small amounts of X-rays as a result of the electron beam's bombardment of the shadow mask/aperture grille and phosphors. Almost all of this radiation is blocked by the thick leaded glass in the screen so the amount of radiation escaping the front of the monitor is mostly harmless. The Food and Drug Administration regulations in 21 CFR 1020 are used to strictly limit, for instance, television receivers to 0.5 milliroentgens per hour (mR/h) (0.13 µC/(kg·h) (at a distance of 5 cm from any external surface and as mentioned above, most CRT emissions fall well below this limit. Early color television receivers (many of which are now highly collectable, see CT-100) were especially vulnerable due to primitive high voltage regulation systems. X-ray production is generally negligible in black-and-white sets (due to low acceleration voltage and beam current) and virtually every color display since the late 1960s when systems were added to shut down the horizontal deflection system (and therefore high voltage supply) should regulation of the acceleration voltage fail.

All television receivers and CRT displays equipped with a vacuum tube based high voltage rectifier or high voltage regulator tube also generate X-rays in these stages, though these stages were universally housed in a metal enclosure called the "high voltage cage" to substantially reduce (and effectively eliminate) exposure. As examples, a 1B3 and a 6KB6 vacuum tube would be installed inside this metal enclosure. For both X-ray and electrical safety reasons, the set should never be operated with the cover of the high voltage cage opened. (Photo of HV cage to follow.)

Toxins: Old CRTs may also have used toxic phosphors, although that is much less common today. An implosion or other breaking of the glass envelope could release these toxic phosphors. Because of the X-ray hazard, the glass envelopes of most modern CRTs are made from heavily leaded glass. The lead in this glass may represent an environmental hazard, especially in the presence of acid rain leaking through landfills. Indirectly-heated vacuum tubes (including CRTs) use Barium compounds and other reactive materials in the construction of the cathode and getter assemblies, normally this material will be converted into oxides upon exposure to the air, but care should be taken to avoid contact with the inside of all broken tubes. In some juristictions, all discarded CRTs are regarded as toxic waste.

Flicker: The constant refreshing of a CRT can cause headaches in migraine sufferers and seizures in epileptics, if they are photosensitive. Screen filters are available to reduce these effects. A high refresh rate (above 75 Hz) also helps to negate these effects.

High Voltage: CRTs operate at very high voltages. These voltages can persist long (several days) after the device containing the CRT has been switched off and unplugged. Residual charges of hundreds of volts can also remain in large capacitors in the power supply circuits of the device containing the CRT; these charges may persist for weeks. (Modern circuits contain bleeder resistors to ensure the high-voltage supply is discharged to safe levels within a couple of minutes at most.)

Those working inside CRT-containing equipment should know how and be able to safely discharge these hazards. In particular, the large rubber connector which looks like a suction cup is responsible for supplying accelerating voltage to the bell of the CRT. Under the suction cup is the ultor which couples the accelerating voltage to the inside of the tube. Inside the glass bell is a coating of metallic paint, while the outside of the bell is coated with a conductive graphite coating called Aquadag; between the ultor's connection to the flyback transformer and the Aquadag, there is therefore a capacitance capable of maintaining the full accelerating voltage for weeks. While this accelerating voltage is high (typically from 7kV to 50kV depending on screen size, monochrome or color, direct view or projection), both the capacitance and flyback current are small (on the order of picofarads and nanoamperes respectively), so shocks from the accelerating voltage are typically embarrassing and painful but usually harmless. On the other hand, the voltages and available currents used in the deflection and power supply circuits can result in instantaneous death.

Implosion: All CRTs and other vacuum tubes operate under high vacuum so that air and gas molecules will not interfere with electron streams. CRTs have large viewing areas and proportionally larger bells required to accommodate the deflection of the electron beams to the rear of the screen. As a result, these highly evacuated glass bulbs have a large surface area, with each and every square inch exposed to atmospheric pressure.

As an example, consider a 17-inch (16-inch viewable) CRT at a mean sea-level atmospheric pressure of 14.7 pounds per square inch. Measuring the visible portion of the CRT and rounding up to the nearest inch (accounting for invisible portions of the face), a Viewsonic model E771 monitor has a screen of 13x10 inches, or 130 square inches. At 14.7 PSI exterior pressure and a near-perfect internal vacuum, the face of this monitor is supporting over 1,900 pounds of air mass on its face alone. The entire CRT is conservatively supporting three times that - or nearly 6,000 pounds, the weight of three typical automobiles - across its entire surface. The larger the CRT, the more surface area, the more total exterior air pressure load.

Therefore, CRTs (outside of finished end-user products) present a hazard to those without proper training and appropriate precautions. While a great deal of research has gone into implosion protective designs for CRTs, all CRTs present an implosion risk. Even CRTs in finished products present a hazard if handled uncautiously. Early television receivers even included a "safety glass" to protect viewers from flying glass due to spontaneous structural failures of the CRT; with modern (early 1960s onward) banded and bonded-face CRTs, the safety glass has become redundant. Safety goggles, leather gloves, and heavy sweaters are considered indispensable safety equipment amongst experienced technicians and preservationists of early television equipment.

High Vacuum Safety

Because of the strong vacuum within a CRT, they store a large amount of mechanical energy; they can implode very forcefully if the outer glass envelope is damaged. Most modern CRTs used in televisions and computer displays include a bonded, multi-layer faceplate that prevents implosion if the faceplate is damaged, but the bell of the CRT (back portions of the glass envelope) offers no such protection. Certain specialized CRTs (such as those used in oscilloscopes) do not even offer a bonded faceplate; these CRTs require an external plastic faceplate or other cover to render them implosion safe while in use. Before the use of bonded faceplates one of the hazards would be that a broken neck or envelope would cause the neck and electron gun to be propelled by atmosperic pressure at such a velocity that it would erupt through the face of the tube.

Unmounted CRTs should always be carried with its face, the heaviest part, down. Use both hands, and grasp the tube under the face, wrapping your hands around to the sides where the metal mounting frame is attached. Never carry a CRT by the neck! For added safety, carrying the tube in a closed, thick box or with a thick cloth wrapped around it (but not in such a way as to impair your grip on the tube) is a good idea; this will reduce the amount of flying debris should the tube break. Large tubes (over 19 inches) should be carried by two people. In general, you should treat the tube like a hand grenade, thinking that if you handle it carefully and keep your grip on it, there is no serious danger, but that it could cause a disaster if you drop it.

When handling or disposing of a CRT, you must take steps to avoid creating an implosion hazard for yourself or your trash removal service. The most simple and safe method to make the tube safe is to identify the small sealed glass nib at the far back of the tube (this may be obscured by the electrical connector) and then (while wearing safety glasses and gloves) filing a small nick across this and then to break it off using a pair of pliers. A loud sucking sound will be heard as the air enters the tube, filling the vacuum. Once the vacuum is filled, the tube is destroyed, but it cannot implode. One must be very cautious not to break the neck of the tube when it is evacuated since there is no plastic coating preventing shattering of the glass. High vacuum and high voltage can be dangerous.

SANOG18-Impressive towards Securing ISP Networks and Services with IPv6 Deployment for Nepalese ISPs

2011-09-20T05:05:00.005+05:30

It’s been almost 7,8 years since I have been teaching Networking and Advance Networking subjects in universities of Nepal. However I am supposed not even perfect in my subject matters what I wanted to deliver practically. Experiences, training, workshop etc are those activities which make us up to date with wide knowledge behind theory only. I became more updated after I joined the IPv6 session of SANOG18 workshop and tutorials (http://www.sanog.org/sanog18/) which was held on 8-16 Sept. 2011 in Pokhara. i really appreciate AI3 SOI-ASIA research project under WIDE university for its intense effort to setup IPv6-Only network in Tribhuvan University, IOE Pulchowk Campus where I am supposed I am the one who setup the IPv6-only Network with v6 enabled Servers (web, mail, Unicast/Multicast routers) first time in Nepal on 2007 after when AI3 announced IPv6 only network in its research network.

After when I got the idea of v6 Networking with its importance and urgency to migrate, it’s really a challenge for the developing country like Nepal. Keeping in mind, I decided to extend the university network with other universities, research institutions within Nepal. However for me like a normal officer, it’s a dream only. I thought I am not the social worker who volunteers in its profession.

In my previous blog, I had written about government’s passiveness regarding networking deployment (http://baburamdawadi.blogspot.com/2010/01/where-is-nepalese-ipv6-task-force.html). I think we Nepalese are really lacking behind the technologies where neither telecom operators nor ISPs, or government is serious in this matter. But I appreciate the Nepalese team of ISPs and NPIX who conducted the SANOG program successfully in Pokhara. Human resource development is the one major portion where SANOG massively supported and empowered ISP administrators toward migration to IPv6 by conducting workshop and tutorials. I appreciate the sponsorship by NTA. However NTA is lacking behind the rules/regulations/guidelines/framework development, it is an indirect support that at least NTA helps ISPs towards the technology migration by supporting the program. Definitely private and non-governmental parties are one step ahead in every aspect with the government in Nepal where I saw the seriousness in private parties rather the government should be.

The world is globalized, the world is converged and hence technology is converging towards the IP based communication. In the near future, even local voice communication will be merged into digital packet based communication (IP based network) where the world wide backbone network is already an IP based. It’s a threat to Nepalese telecom operators if they are still reluctant to the legacy voice communication which leads to so called illegal call bypass. In this context, secure and reliable national IP backbone network is the solution which immediately Nepal government has to think. The sad thing is that still government doesn’t know what are the current IP network infrastructures and its security policy. Currently, the ISP networks are the government asset as national IP network. It is necessary to evaluate the ISP network infrastructure which helps government to design the national backbone network. Government talks about lawful interception, monitoring and controlling of VoIP traffic as well as other relevant security issues. It is possible only if the network infrastructure is well designed and documented.

Since last 1,2 years, illegal VoIP is a threat to government and NTA has processed several steps toward the control over. NTA collected ISP details, ISP client’s details, ISP IP address (IPv4 address only) distribution and also moving towards the database software development to properly maintain the IP and ISP information. This is appreciable. However it’s hard to control the illegal VoIP due to mutation in technology. IPv6 addressing infrastructure is almost deployed world-wide however it is not shown in frontline. There are so many techniques enabling IPv6 network over network (tunneling, dual stack, transition). Now it seems that it is out of control if call bypass uses IPv6 network so called VoIPv6.

What is VoIPv6?
It is voice over internet protocol version 6. The technology enables us to exchange audio/video/text/image (telephony signals) traffic within the IPv6 network environment.

Whatever applications developed in IPv4 for VoIP operations are also developing in IPv6 infrastructure too. For example Asterisk is an open source/free software implementation of a telephone private branch exchange (PBX) originally created in 1999 by Mark Spencer of Digium. Like any PBX, it allows a number of attached telephones to make calls to one another, and to connect to other telephone services including the public switched telephone network (PSTN). Its name comes from the asterisk symbol, *, which in Unix (and Unix-like operating systems such as Linux) and DOS environments is a wildcard character, matching any sequence of characters in a filename. Asterisk was ported to IPv6 by Viagénie in 2007 (Asteriskv6).. http://www.afnog.org/afnog2008/conference/talks/VoIPv6.pdf.

VoIP over V6 is more reliable and secure as it ensures QoS. As we know that IPv6 implements QoS with the help classification and marking (of IP packets) to ensure a reliable VOIP infrastructure. With the help of classification and marking technique, the network can identify packets or traffic flows and then can assign certain parameters within the packet headers in order to group them. In order to implement QOS marking, IPv6 provides a traffic-class field (8 bits) in the IPv6 header. It also has a 20-bit flow label.

VoIPv6 is more reliable and efficient
Exhaustion of address space is another issue as the momentum of VOIP grows significantly. The 32-bit address space in IPv4 precludes its scalability to a large user base. IPv6 addresses this problem of IPv4 with a very large address space that consists of 128 bits. Therefore, it is now possible to support 2^128 unique IP addresses, a substantial increase in number of computers that can be addressed with the help of IPv6 addressing scheme.

Also, in order for VOIP to be widely deployed, security concerns such as eavesdropping and hacking must be addressed as well. The other issues that impact VOIP: 1) End-to-end Integrity of signaling and bearer paths details 2) IP (voice) packet delivery across firewall and 3) NAT (network address translation) addressing issues that cause several networking problems (such as hiding multiple hosts behind pool of IP addresses) in end-to-end nature of the Internet and 4) Preventing denial or disruption of service.

Now, it is also notified that it is time towards v6 network measurement and evaluation with extending knowledge towards data network and services, current ISP network deployment issues and many more. It’s a challenge for the government especially to memo (TIPPANI) oriented professionals who definitely lacks behind fresh technologies leading to adaption problem if government still don’t think about human resource development.

My Diary-2067 (2010/2011)

2011-04-17T15:26:00.005+05:30

Stable, the most stable and the exciting year 2067 for me. I found myself almost successful in my every job and activities throughout the year. However I became offset when a pocket picker picked up my mobile during Nepal banda in May. I walked to office by foot during the day so called strike announced by Maoist. Hence I lost my set what I purchased from Singapore during the conference visit. It was a nice Samsung set with so many functionality.

I became quite busy during the whole period of year 2067. The cause was my added responsibilities in my office due to the shortage of human resource in the engineering section of NTA. I am supposed to be a bit more experienced in the event management which I managed a couple of times before while I was in Institute of Engineering (IOE) Pulchowk Campus. I remember the day while on IOE that two times I was able to organize Free Students Union Election through software voting. These ware quite risky events what I had decided to handle and managed all technically. It made me experience what I gained in my life. The event what I followed is workshop “SATRC” (http://baburamdawadi.blogspot.com/2010/08/2nd-international-event-management.html) which was successfully conducted by the NTA team in which I was one of the team member.

Government decided to band porno sites via the ISP network and services. The responsibility was given to me to be a focal point to verify the legality of the sites and issue letters to ISPs. The job became quite tough for me because I hadn’t have the guidelines (Code of conduct) to make sure that any complained site is porno or not. It was one of the criticizing decisions. Unfortunately some musical and news related sites were listed on the illegal list. This was simply a pretty mistake that was done to find the illegal sites searching through Google with the work “Sex”. It was gonna be an international issues what I realized after I got a call from US Embassy in Nepal. However the whim calm down soon after NTA reviewed the list. Still it becomes the subject of debate. I knew, we can’t block millions of site that can easily be downloaded from blacklist.com. Although, it’s government responsibility to control someone’s illegal activities to stop making people harass and blackmailing within the country. May be someone of our relations might be in such situation. Again the debate is the technical implementation. “The control should be on the Network Service Provider (NSP) side”, said ISP. But NSP said, “It’s not under our license condition as whatever content flows through network that is not our concern and we are just the bandwidth provider”. May be it could be better to set under the framework of lawful interception and make control over international gateway.

Year 2067 hit me with another issue that is VoIP crime within the country. I became the member of VoIP illegal call bypass control committee within NTA and coordinator of MRTG (Multi-Router Traffic Grapher) investigation of ISPs. VoIP is legal but it is made illegal by the telecom operators. Telecom operators don’t want to implement VoIP license which leads to maximum profit to those who are illegally doing their business in call termination. Government tried to control these illegal activities by the massive operation carried out by the CIB (Operation Voice Fox) in one hand and on another hand CIB and NTA collaboratively started investigating MRTG of each ISP. MRTG is one weak technique to suspect activities in illegal call bypass however support from ISP is the most on this matter to properly identify it. I don’t know why ISPs neglect government. Whenever NTA fetched letter to ISPs for the information, it’s very hard to get back the reply. I visited almost 10/15 ISPs within the Kathmandu valley for the monitoring of ISP system with MRTG. Some of the ISPs are the ISP only without any infrastructure. Seems it’s very hard for them to sustain in the market. However they are struggling. The ISP market is in decreasing scenario. Either the state plan for the sustainable market model or otherwise within the next 10 years 3-4 ISPs only come into existence and all other more than 40 ISPs have to think for alternative sustainable business by themselves.

The root line what I think to control illegal call bypass is the “SIM” or Telephone Line. I learned on the newspaper many times that thousands (bundles) of SIM were illegally distributed which leads to illegal call bypass. Operations Voice Fox is quite appreciable and NTA’s prompt decision to control VoIP is also measurable. These days the operation constitutes to increase in operator’s revenue. But the SAD thing is they provide the SIM illegally and blame that government is as being passive on this matter. But happiness is that CIB and NTA both are in operation to make telecom operators more profitable and able to increase the tax for the government. Tax is just 25%, the rest 75% goes to operators profit pocket. That’s why I would like to request telecom operators to remember your 75% increase in profit and fully control SIM Distribution. Until and unless SIM distribution is not managed, the illegal activities never end. NTC opened up SIP call for NRN that makes one part of the investigation more complicated. Whenever anyone gets a call from abroad and the phone number of the caller is local then we simply informed to authority/CIB/Operators to blacklist the SIM immediately. But partial opening of VoIP by NTC makes us confused whether the call originated is legal or illegal. With the license, it is necessary to advice operators to set the range of SIMs for VoIP and inform to public about the legal SIM range.

Surprisingly, I got an opportunity to participate on the ACMA/ITU international Training program (http://baburamdawadi.blogspot.com/2010/12/events-and-trip-from-beginning-were.html). It was my memorable moment of the year 2067. This program encouraged me to expose on the field of telecommunications via policy and regulatory aspects. This program highlighted a policy that was Australian Broadband Policy developed by Mr. Colin Oliver in support of ITU. Whenever I returned back from Australia, NTA approved the ITU project for Nepal Broadband Policy “Regulatory Guidelines on Broadband through Universal Service”. (Glimpse of Workshop Below).

Visit to Nepal Telecom in Broadband Mission Program

Workshop Program at Radisson Hotel

Workshop Inauguration

ITU decided to bring the same Australian broadband master planner: Colin Oliver for Nepal. It was my another exciting moment in the year 2067 to successfully complete the ITU mission program and conducted half day workshop “Stimulating Broadband in Nepal” (http://www.nta.gov.np/en/content/index.php?task=articles&option=view&id=65). Now NTA received the draft report of the mission program. Hope this guideline helps Nepal to be a broadband country.

New Entry in 2067: Cherisa

The most exciting moment of the year 2067 is being a father of a daughter. I achieved to be a father of my first baby after a successful surgery. Now more responsibilities added to me. During the moment, I spent a week in Patan Hospital. But it’s amazing seeing the service scheme provided by Patan Hospital. It is like “service government; payment private”. Whenever we choose a private ward, the charge on every category ( eg: operation, delivery, nursery et…) is at least two/three times the general. I thought that the private hospitality would be definitely better. But they are staffs of government hospital and so service is never like private. I paid Rs 16,000 for the same type/pattern of surgery instead of Rs 8,000. My temporary friend was quite happy that he paid Rs 12,000 only for the same case while I paid Rs28000 (bebkufff…).

I don’t know whether I am happy or sorrow with my written exam result by TU Service Commission. I appeared on the exam of Asst. Professor in the year 2067 and am eligible for interview. The set of rules into the recruitment criteria by TU is quite embarrassing. However the manipulated rules are not written on the TU RED BOOK but the recruitment committee has set of readymade rules to create its own favorable situation: (Rules on Open Competition; I don’t think that it’s an open competition).

TU announced vacancy with open competition. It counts experiences, thesis supervision, papers published on the journal, research/training and Ph.D. Marks.
The amazing thing is that experience is countable only the applicant is faculty of TU Campuses. Even one can’t provide the teaching experiences of Private TU-affiliated colleges. TU don’t recognize professors, lecturers of Purbanchal, Pokhara and Kathmandu University.

Another interesting thing is thesis supervision. Thesis supervision within Masters Degree of TU campuses only is countable. Those who supervise thesis in KU, PU are useless.
The most interesting thing is the research paper. Research performed during master’s degree and paper published during master’s degree is not countable. As all of these are to be done to gain the degree. All the papers published to achieve degree are not acceptable.

The level of experience, national/international papers, and thesis supervisions may lead the marks. But these are nothing behind the interview marks (30) allocated for. Peoples are on the big political playground with the objective candidates are elected based on the advertisement and appeal for voting. Seems no one appeal for the vote would definitely defeat the election. So I would be the one who defeat the case because I am not appealing for the vote and it’s not necessary for me to appeal too. I think professional power is better than political power for the long lasting future. Target can be achieved from anywhere.

The year 2067 with NTA is very encouraging, experiencing, exciting, favorable and fruitful for me. I am expecting the same for the coming years.

“HAPPY NEW YEAR 2068”.

Learned from Murai Lab: Improve efficiency in office work

2011-01-13T14:51:00.001+05:30

Murai Lab, one of the popular internet research labs of Japan founded by Prof. Jun Murai, the father of Internet. The lab is a two story building where the ground floor consists of the network operation center with meeting halls, secretariat room and online class multicasting center. The upper floor is the research center where at least 8-10 researchers continue research on especially new internet technologies with latest IP addressing mechanism: IPv6.

I am writing here just about how the efficiency of office work increase and save the energy of one when you gonna meet your senior/boss/professor or whoever without moving from your table. Guess, in Nepal, what happens if an office has five story building where your boss is on the top floor and you are in the ground or middle floor, almost time to discuss with boss, either you have to use lift to meet him/her any time when he/she calls or use the steps. What if, you gonna meet 8-10 times a day. May be we need more energy for it and time consuming too. Instead of this, we can use phone conversation but sometimes phone conversation only is not effective. Sometime due to concentration in other works may not make the phone conversation fruitful. Hence, either video call or face to face meet is necessary.

So, for time and energy saving in office work, you need to have following:

First of all, in your office cabin, you should have either laptop or desktop with headphone set.
Make sure that you have different kinds of communication tools like internal phone, cell phone, yahoo, msn, Google talk, Skype or any other kind of messenger with your notebook/PC and web cam that enabled your effective communicate with other office staffs.
When you log into your cabin, log into your all communication tools first and set the status as per your work load. Sometimes its emergency to talk with friends in messenger when mobile phone connection is ……..(in Nepal..). Voiceless communication is suitable than voice communication during office time to avoid disturbances to other office staffs. However it is urgent sometimes with voice and video communication needed. In this regards, using microphone is better. You can talk with other colleagues, senior and bosses within the same flat, building or outside using Skype like tools.
Browse social networking sites like face-book, hi5 etc during lunch hour or during the last office hour (after 3PM). These sites are just for your refreshment and if it is opened from the beginning of our office time, it could never ends as it is like habitual drugs continue browsing that leads to your all office works into pending with low priority.
If you need to consult with other staffs (senior, junior…) for your work completion, use text messaging first. If messaging only is not sufficient you may have internal phone call or follow the video call using Skype like tools.
Request peon or helper to handover your file to be submitted to super-ordinate/sub-ordinate.
Transfer softcopy file through network sharing or using local mail.
Appear online video conferencing call if you need to have peer communication, meeting and group discussion.
Complete the every file task within three days after you receive or response at least, even if it is not followed up.

It is also necessary to freshen up frequently during the work. Continuously sitting in a single table and works load make staff monotonous and more tired. It is obvious that there might be the possibility to misuse internet and other resources. It is necessary to monitor on it. Social sites and video sites like YouTube should be allowed during lunch hour and at the end of office time only. All the office staffs should be aware of using computer and internet properly. Every PC/notebook should have broadband connection with at least 512Kbps speed so that there are no any disturbances during the video communication.

What I have written above is what I learned and saw after I joined Murai Lab where almost meetings and any other office activities were performed by text/audio/video communications. It is necessary to implement (however it is not a big deal but a big deal for Nepal) such technique for improving efficiency of office work in Nepalese office system (especially to government offices).

Events and Trip from the beginning were Memorable

2010-12-22T16:38:00.001+05:30

I was quite socked when Ministry of Foreign Affairs denied processing my visa letter simply forwarded by the line Ministry MoIC. However I am supposed working for the government of Nepal, It was my unfortunate treating like third class people. It was already late for me to process the visa. Almost 19 days left to apply for VISA to Australia. Finally I had decided to process directly from my office through visa counselor to Australian Embassy located in New Delhi, India. The last 16 days of my visa processing was quite embarrassing for me whether my visa would be accepted or rejected. I really feel sad that one Nepalese backbite another Nepalese; Australian government treated me as Nepalese Citizen and so permitted me by providing multiple entry visas. I was in rush during the day before my flight, because I just got the passport at the last moment and so nothing was decided and managed before departure. It was a five days training program from 6-10 December 2010 at Sydney, Australia. NTA nominated me to participate on this program. As per the program scheduled, I had talked with Roshan (my brother in law) who is almost well established in Sydney, managed my stay and trip at Sydney. However the schedule was quite tight, the available time was perfectly utilized by having sightseeing and visiting friends and relations.

Me with Narayan Adhikari (quite soft person from MoIC), enjoyed the program with 100% satisfaction. We purchased one week local travel ticket from the train station. The ticked was valid to travel by bus, train and ferry within Sydney. Arncliffe to darling harbor, from resident to training center, our daily schedule was set. The training center was located at the center of Sydney which is at darling harbor opposite of Sydney Convention Center and the world’s biggest theater iMAX with Sydney aquarium and wildlife world. Friends told us that, if I purchase the combo ticket for aquarium, wildlife, tower and ocean-world then Sydney tour would be finished with visiting Opera House.We purchased the combo ticket in AUS $50 (quite expensive, I realized). I thanks to Roshan and next brother Mr. Sharad Kharel who were keenly interested to extend my stay and trying to plan to go another city. However it was not possible to extend the ticket for the short period of time.

The main objective of the international training program (ITP) was to offer a comprehensive overview of and insight into Australia's contemporary communications regulatory environment with a focus on the implications and challenges of convergence. The ITP also included international speakers who will discuss their country's specific experiences and lessons learned with the following focus topics:

Communications and media regulation in a digital society

Promoting competition, choice and public benefit

Digital economy: Risks, challenges and opportunities

Promoting end-user access and safety

Promoting compliance

The training was successfully completed in a peaceful environment at the dockside lab, Darling Harbor, Sydney. The training materials and other resources provided were more than sufficient to gain the knowledge. There were almost eighty participants from all over the Asia-pacific region with participation from the African country “Kenya”.

During the first day (6th Dec.), the training program was inaugurated jointly by the deputy chair of ACMA and Regional Director of Asia and the Pacific. Throughout the training program, almost presenters were from the expertise of ACMA including the presenters form Malaysian Communications and Media Authority (MCMC), Bhutan InfoCom and Media Authority (BICMA), Department of Broadband, Communications and Digital Economy of Australia, Australian Competition & Consumer Commission, Australian Mobile Telecommunications Associations, Australian Telecommunications Users Group, InfoCom Development Authority of Singapore, Internet Society of Australia and International Telecommunications Union (ITU).

Presenters from Indonesia, Papua New Guinea, Malaysia, Samoa and New Zealand had presented their country experiences regarding the regulation and ICT issues with their case study pilot project. All the presentation materials would be available via NTA’s Digital Library system soon in the near future.

I had have great experiences of having such an wonderful training which helped me to gain knowledge on regulatory challenges, spectrum management, infrastructure sharing, mobile broadband communications, citizens security, national security issues: cyber safety, e-Security, digital economy with future communications and media/content regulation. Training is such a tool which definitely helps to improve one’s level of confidence in his/her expertise. This training program gave me broad idea about regulation issues like media regulation, content regulation, anti-spamming, spectrum etc which is necessary for me to handle my responsibilities more effectively within my designated post in NTA.

It was not my first abroad visit. After visiting Japan, Singapore, Philippines and Malaysia, I felt Sydney is comparatively more comfortable for me. Singapore is high paced city however it is English speaking. Language problem with Tokyo. Sydney peoples are a bit more socialized I found. It seems choosing Sydney, the migration venue is better I think. I always get frosted for about one month when I got back to Kathmandu from abroad. By seeing the development, environment, peoples civilization abroad, all in all, Kathmandu, how can I imagine that one time Kathmandu will be on that position. Never never and never…ever. Political leaders, government officials… doctors, engineers, lawyers..Professors…no one is dedicated and committed to the country then how could Nepal would be on that position. Eisahi hey, chalraha hai..chalta hai..

रोशन, चन्द्र र नारायन ब्रोहरुलाई धेरै धरै धन्यबाद!!

Finally I am so sorry with those friends to whom I could not meet however I was nearby you into the city. Let’s hope to meet with you next time when the time cycles back to me.

मेरो नेपाली पत्र र बिधुत प्राधिकरण।

2010-10-12T17:12:00.000+05:30

म आफ्नो ब्लगमा जहिले पनि जानी नजानि English मा लेख्न कोशिस गर्छु। किनभने कहिलेकाहीं मलाई बाहिर जाने चक्कर दिमागमा आउंछ। तर बाहिर जानको लागी TOEFL/IELTS/GRE मा टन्न हान्नु पार्छ। तसैले English Practice गरेको। आर्को कुरा मैले पढेको नेपली लगभग पोलेर खाइसकें। तर जब मेरो नेपाल दूरसंचार प्राधिकरणमा जब सुरु भयो, तेहि दिन देखि नेपाली भासाले मलाई छाडेन र मैले पनि नेपाली practice सुरु गरें। टिप्पणीं लेख्नु पर्ने ति माथी पुरा भासा मिलाउनु पर्ने। शुरु शरुमात गाह्रै पर्यो। नेपाली युनिकोड आएतापनि राम्रो शुद्धिकरण चाहिने। सिनियरहरुको सहयोगबाट आजकाल भने अलि अलि आउंछ। तर अझै पर्फेक्ट त कहां छु र?

यो नेपालीमा पत्र र टिप्पणीं लेख्ने बानिले होला नेपाल बिधुत प्राधिकरणको एउटा कर्तुतलाई पत्रका मार्फत यस ब्लगमा हल्न मन लाग्यो।

केहि समय अघिको कुरा हो, हाम्रा छिमेकी तिन जनाले १/२ बर्ष अगाडीनै Single तार लाई नजिकैको पोल सम्म बिजुली ल्याएर प्राधिकरणकै सहयोगमा point निकाली (लेगल्ली निकालेको प्वाइन्ट हो) मिटरबक्समा बिजुली जोडे। तेहि पोलबाट नयां ग्राहकलाई बिजुली दिनको लागी नयां ग्राहकले पुरानो ग्राहकसंग लिखित सहमती दिएपछिमात्र प्राबिधिक क्षमताको आधारमा प्राधिकरणले नयांलाई बिजुलि दिने रहेछ। तर हाम्रा छिमेकीले के गरेछन भने, तारसंग सम्बन्धनै नभएकासंग खुसुक्क सहमती लिएर प्राधिकरणमा निबेदन ठोकेछन बिजुली जोडिपाउं भनेर। तर संबन्धित पोल र प्वाइन्टबाट लाइन तान्नलाई पुरानो ग्राहकले थाहा दिनु पर्ने भएकाले technician लाई यसो मिलाएछन (अब तपाईंले बुजिहाल्नु भयो नि प्राधिकरणका टेक्निसियन न हुन् तिमाथि नेपालका सरकारी कर्मचारी!!!!! हुन त म पनि सरकारी कर्मचारीनै परें.........................तर कसरी मिल्ने मिलाउने भन्ने चाही अझै थाहा छैन हई सांचो भनेको। ईज्जतको पनि सबाल छ नि तेसैले)। र प्वाइन्टनै नभाको आप्नै घर आडको पोलबाट मारी तारलाई काट्न लगाएछन र टेपले टालटुल पारेर कोही नभाको मौका पारी बिजुली तानेछन। अब प्राधिकरणले यसरी बिना सर्भेक्षण तार काटी बिजुली जोडीदिन्छ,कस्तो होला हाम्रो नेपालका बिजुली प्राधिकरण र यस देशका हामी जनता। प्राधिकरण आफैले यस्तो अनैतिक काम गरेकाले सम्बन्धित expandable Point बाटै बिजुली लैजान जानकारी गराईसकेका छन छिमेकीले तरपनि...अब हेरौं। अब कुरो रहयो काठमौंमा घर बनाउने समृद्ध मानिसको यो कामको। मेरो बानि अलि नराम्रो छ, कसैले नराम्रो काम गरेमा उसैलाई हानि हुन्छ तेसैले चुप लाग्नु बेटर>>यो बानि खासै ठिक हैन। तेसैले मैले भने यसपाली एउटा लेटर ड्राफ्ट गर्ने निर्णय गरें। मेरो आफ्नो जब को प्राक्टिसले गर्दा होला मलाई कम्पलेन लेटर ड्राफटगरेर हाम्रा पिडित छिमेकी लाई दिन मन लाग्यो।(कुरो के भने मेरो आफ्नै परिवार यसमा मर्कामा पर्यो बाबै...)। मलाई आजभोलि अलि दिक्क लाग्यो, छिमेकीको यो व्यवहारले। छिमेक भनेका त मर्दा मलामी जिउंदा जन्ति भन्छन। मिल्ने मिलाउने भन्दा झन तनारिने काम र बिधुत प्राधिकरणमा फेरी आफ्नै साथि हाकिम छन। आफ्नै साथिले यत्रो अनैतिक काम हुंदा पनि कानमा तेल हालेको देख्दा पनि अचम्मै!!! हुन त मैले एक पटक पनि कन्ट्याक गरेको छैन उहांलाई। अब सबै काम नियम संगतनै होला भनेर कन्ट्याक नगरेको र यस्तो कन्ट्याक गर्ने भनेको अनियमित कामका लागि मात्र हो भन्ने म ठान्छु। निबेदन परिसकेकाले उहांलाई ताकेता गर्नु जरुरी पनि छैन। केबल मुख्य कुरा के भने मानबता र नैतिका ठूलो हो भन्ने म ठान्दछु।

मैले बिधुत प्राधिकरणलाई लेखेको नमुना पत्र तल हेर्नुहोला। (यो मेरो अहिलेको जब को ठूलो भुमिका छ यस्तो लेटर ड्राफ्ट गर्नमा, यदी यो लेख पढ्नु भयो भने लेटरमा गर्नु पर्ने सुधारका बरेमा औंल्यइदिनु होला। यसले मेरो जबलाई पत्र/टिप्पणी लेख्न थप सहयोग पु-यउंछ भन्ने मैले आसा गरेको छु।)

बिषय: बिना सहमती बीचबाटै बिजुलिको तार काटी बिजुली प्रयोग गरिएको सम्बन्धमा।

महोदय,

प्रस्तुत सम्बन्धमा बनश्थलि, एकलटार बस्ने प्राधिकरणका हामी तीन ग्राहकहरु (क्रमश: …………….चित्रकार, ………….…….बन र …………………………दवाडी) ले मिति ………………….बाट आफ्नो घरमा बिजुली प्रायोजनका लागि हाम्रो क्षत्रदेखि करिब ४०० मिटर परको पोलबाट सम्बन्धित ग्राहकसंग सहमती लिई हाम्रो घर नजिकैको पोल सम्म single तार तानी बिधुत प्राधिकरणको सहयोगमा आबश्यक Points निकालेर आ-आफ्नो Meter Box मा जोडी बिधुत प्रयोग गर्दै आएको व्यहोरा अबगत गराउंछौ।

यसै सन्दर्भमा बिगत केही दिन यता हामिले आफ्नो घरमा पाउनु पर्ने minimum क्षमताको बिजुलीमा Disturbance भएको पाईएको र यसै एकलटारमा घर बनाउंदै गर्नुभएका श्री ………………………….. जि ले हामीबाट कुनै सहमति नलिई, हाम्रो नजिक रहेको पोल र extension गर्न मिल्ने point बाट बिजुली नतानी point नै नभएको पोलबाट हामीले प्रायोजनमा ल्याएको तारलाई बीचमै काटी बिजुली प्रयोग गरिरहेको पाइएको। यस्तो अबस्थाले निम्न कुराहरु देखिन्छ।

हामी तीनजना ग्राहकलाई कुनै जानकारी नदिई र कुनै सहमतीपनि नलिईकन बीचबाटै तार काट्नु र बिधुत प्रयोगमा ल्याउनु बिधुत ऐन २०४९ अनुसार अनैतिक कार्य भएको र यस कार्यलाई हामी बिधुत चोरी गरिएको ठान्दछौं।

हामी ग्राहकको बिधुत Safety, Security र Protection बिधुत प्राधिकरणको मुख्य सरोकारको बिषय भएकाले यसरि बीचैमा तार काटि टेपले टालेर तार तान्दा भबिश्यमा हुन सक्ने खतरा (Lightning, Earthquake, High Voltage Over Line) र यसबाट हुन सक्ने मानविय/अमानविय क्षतीलाई बिधुत प्राधिकरणले मधयनजर राक्नु पर्ने देखिन्छ।

बिधुत प्राधिकरणलाई अन्य ग्राहक (जसले सम्बन्धित तारबाट बिजुलि प्रयोग गरेको देखिंदैन)को सहमती देखाई प्राधिकरणबाट अनुमति लिने काम गरिएको केबल प्राधिकरणलाई झुक्याउने काम भएको देखिन्छ। यसरी आफ्नो सम्बन्धित तार नभई अरुको तारमा बिजुली प्रयोग गर्ने सहमती दिनेले यस्तो अनैतिक कार्य गर्न उक्साएको हाम्रो ठहर छ।

बिधुत प्राधिकरणका टेकनिसियन (जसले बीचमा तार काटी Meter Box मा तार तान्ने काम गरे) लाई Expandable Point बाट बाहेक यसरी अरुले प्रयोग गर्दै आएको तार काटी बिधुत जोड्न कुनै ऐन/कानुनले अनुमती नदिने हाम्रो ठहर छ। यस सम्बन्धमा प्राधिकरणकै सचेत कर्मचारी/Technician बाट भएको यस कार्यको हामी निन्दा गर्दछौं।

समृद्ध समाज निर्माणमा हामी जस्ता सचेत ग्राहक, सेवा दिने सेवा प्रादायक सबैको ठूलो भुमिका रहन्छ। यस्तो कार्यले भबिश्यमा हुनेसक्ने यस्तै कार्यलाई प्रोतसाहन मिल्ने देखिन्छ। साथै आज बिजुलिको तार काटी सेवा लिनेले भोली टेलिफोनको तार, केबल टिभिको तार, इन्टरनेटको तार तथा अन्य तार पनि काटी सेवा लिन सक्ने अनैतिक कार्यलाई निरुत्साहित गर्नु हामी सबैको कर्तब्य हुन आउंछ।

श्री ………………………….. जी लाई हामीले Expandable Point बाट बिजुली प्रयोग गर्न सहमती नदिने कदापी भनेका छैनौं र बिजुली प्रयोग गर्न दिन्न भन्ने हाम्रो अधिकारको कुरा पानि हैन। एक सचेत नागरिकका हैशियतले समाजमा गरिने संयुक्त कार्यमा सहमतिको आबश्यकता पर्छ। यहि हुनाले प्राधिकरणले यस्तो कार्यमा सहमती लिनु पर्ने उल्लेख गरेको हाम्रो बुझाई छ।

Existing तारबाट ग्राहक थप गर्दा प्राबिधिक रुपमा तारको क्षमताको बारेमा सम्बन्धित प्राबिधिकबाट सल्लाह मुताबिक काम हुनु पर्नेमा यस बारेमापनि कुनै प्राबिधिक बश्लेषण नगरी ग्राहक थप्नाले पहिलेका हामी ग्राहकहरु मर्कामा परेको हामिले महसुस गरेका छौं।

तशर्थ, बिधुत ऐन २०४९ को दाफा ‘१९’ को उप-दफा ‘घ’ बमोजिम यसरि गरिएको अनैतिक कार्यलाई निरुत्साहित गरि सम्बन्धित बिधुत खतराबाट बंच्न र सम्बन्धित expandable point बाट प्राबिधिक बिश्लेषण गरेर मात्र प्राप्त क्षमताको आधारमा बिजुली प्रधान गरी समाधान खोज्नकालागि श्री नेपाल बिधुत प्राधिकरण समक्ष यो निबेदन पेश गरेका छौं।

2nd International Event Management Practice: SATRC workshop on Spectrum Management

2010-08-26T14:37:00.005+05:30

I guess, I have good experiences in teaching, systems engineering, network engineering, software programming.... I want to extend my experience in gaming like volleyball, basketball etc..but due to professional life lacking me behind from my game zone. However overall I want to extend my experiences in every field that I never ever have/had before.
Last time when I coordinated for the workshop/meeting of AI3/SOI IPv6 project held in June 2009 at Hotel Himalaya Kathmandu, I felt very tough with all the activities like hotel management, delegates management, conference room setup with video conferencing (IPv6 tunneled to SFC Japan) bla bla bla..i was almost harassed due to the lack of coordination among the team members of the working committee. I learned a lot from that event regarding the conference event management.

This time, i am very lucky. Though its been seven years since I have been involved with my profession, I am fresh Asst. Director of engineering section of Nepal Telecommunications Authority. However NTA has selected me to be a team member of this SATRC WORKSHOP on SPECTRUM MANAGEMENT. Thanks to NTA and especially thanks to SL HADA sir for letting me into the team and have a trust. The team is quite strong and well synchronized such that due to the favor of Chairman and with the biggest favor and encouragement from our Director (Ananda Raj Khanal), I hope the program was successful and the memorable one. Working together into a team member is not an easy task due to the involvement of different people with different nature/habit and for the case in Nepal: with different political background. However if a team only focus over the work/responsibility and think for institution with common consensus avoiding individual selfishness and politics, the team work really became fruitful. This is what I felt from this nice coordination and work dedication with us in our perfect SATRC team. Definitely my previous experiences helped me out for this event management.

Asia-Pacific Telecommunity has its sub executive body to address issues of telecommunications within the SATRC member countries. Every year the SATRC workshop is organized in any one SATRC member countries in round robin basis. This year however Nepal is placed under an alternate country for this workshop, we got the chance after Bangladesh had decided not to host due to some unpredictable circumstances.

The SATRC Workshop on Spectrum Management is a part of the implementation of SATRC Action plan Phase III which was adopted at the 11th SATRC meeting in 2009 in Colombo, Sri Lanka. The workshop will discuss a number of issues related to spectrum management in the SATRC region. It will assist the Regulatory bodies of the SATRC member countries in their human resource development needs for acquiring knowledge and skills in spectrum management related regulatory and implementation matters. It will provide an excellent opportunity to exchange views and experiences among the SATRC member country’s regulators and operators on the issues as mentioned. (http://www.aptsec.org/2010-WS-SM).

19-20 Aug. 2010 at Radisson Hotel, the workshop was completed successfully. Delegates from different countries (Afghanistan, Bhutan, Bangladesh, India, IR Iran, Lebanon, Maldives, New-Zealand, Pakistan, Sri-Lanka and Thailand) were successfully arrived in Kathmandu in 18th August when I and Sandip (asst. director of economic and consumer section) welcomed all the delegates at the immigration point of Tribhuvan International Airport. We had managed Nepal Telecom GSM SIM card for every delegates and hence provided at the airport to make our delegates more comfortable with their stay in Nepal.

I am almost new in telecommunications, especially in spectrum management. I was quite interested to join and see the presentations of all papers on this workshop but being into the workshop management committee, i didn’t let myself to attend the program. Cross-Border interference, spectrum band management for different mobile technologies, spectrum pricing and regulations are the current major issues of the country. Due to Spectrum limits the operators. Every country can’t increase operators and it’s hard to develop competitive markets in telecom due to spectrum. So far from the view of different organizations, operators and specialists, spectrum distribution in Nepal is unfair. We should have to have spectrum re-farming and manage the spectrum in a proper way so that there won’t be any discrimination in the frequency band distribution.

i hope,this workshop taught us a lot about the conference management further. "Experience is better than learning theory".

"YOU ARE IN RIGHT WEIGHT", GREAT!!

2010-07-24T07:31:00.004+05:30

Since last six months, I have been experiencing a big time management problem. i think i need to draw UML Time Diagram for me. I don’t know how could i had provided time to seven engineering colleges to teach my elective subjects: “Data Warehousing and Data Mining”. Probably I applied such an algorithm that might be new in artificial intelligence … he he he..BIM, BE and M.Sc. Engineering students and varieties of experiences with them. Wakeup early morning, leave home for teaching and come home back around 9PM night. It was my last six months daily routine. Even in Saturday 6 AM to 5 PM engaged in teaching. I think i had broken up my wife’s hurt several times, I never think allocating time to her due to my over busy time. I knew I got SMS message several times, phone call several times but I hadn’t have time even to watch SMS and pickup phone. But being a computer engineer (same profession with me), she has nice understandings with me. This is what I have achieved with my lovely wife>> understanding. I always deferred her request to have leisure time with her like watching film, shopping, occasional visit to relatives etc etc..

It is too much!! I am saturated with teaching. Data warehousing and Data Mining is my elective subject teaching since last 7 years and almost 20/22 semester groups were already passed out even though I have to learn more and teach more on this subject to my students. Being a system/network administrator in IOE Pulchowk campus, my favorite subject is networking and internet technology which leads towards research over Network security and QoS. It could probably my future destination in research.

Finally during the middle of the training that was held in Healthnet Nepal on last Thursday, i went NTA and completed the simple task, I got free time after 3PM, so granted to have shopping with my gal. But the problem is government job holder, not sufficient money in my pocket. But I am happy with her first month’s first salary in her life and she was quite excited to purchase something with her first income. I am also happy that now she has her own income. I am frustrate with some private engineering colleges who still delaying my remuneration of last semester. New semester has already been started. It is better to teach to selected college with selected students only, I feel myself not good to be a helmet faculty any more.

Bishal Bazaar shopping complex, I think Nepal’s the very old shopping complex is still seems better for shopping. During last 30 years of my age, I never found my weight above 54Kg. 48KG in SLC, 48KG in I.SC, 52KG in BE, 53KG in Masters.. However the level of education increased my weight never increased. Whenever I stand into the weighing machine, the slip wrote, “YOU ARE UNDER WEIGHT”. Whenever I felt myself increase in weight immediately I went for weighing but no considerable improvement. Since last 2 years, I never thought of weighing anymore because I am tensed, I could never be fatty. But this time, this time the weighing machine showed “YOU ARE IN RIGHT WEIGHT”. Again I am in more tensed, because I am getting fatty..Looking odd with stomach size increment. So people never get satisfied. Previously I always roamed to get solution about how to get fatty but now onwards I have to get solution to become fit. Anyway the 3hrs shopping was interesting and the memorable one and I hope I am excused. with my all negligence i did. New semester has already been started..probably the last schedule may be repeated…:p.

MAC based security enforcement System for individual Mobile Device Security

2010-05-06T15:23:00.001+05:30

The story began with the day when I lost my mobile, I mean, the mobile set picker picked-up mobile forcefully when I attended the political speech by Dr. Babu Ram Bhattarai, conducted during the maoist strike program on 2066/01/21 at Sundhara Kathmandu.

I heard that YCL, the brother body of United Nepal Communist party (Maoist) is well organized and honest one. YCL members are well disciplined and they do for people. I was quite positive to get my mobile set back after when I had identified the picker just immediately I found that my mobile was picked-up and got submitted to YCL member. They (YCL) convinced me that they would get back the set after enquiry and punishment to the picker. I just left them enquired and call whenever they get the set back from the picker. But unfortunately, my expectation just became expectation only. Finally I lost my mobile and became contactless with all my friends and family until the strike closed. But it’s an infinite strike which is leading the country towards the worst situation more and more.

There were so many important numbers saved within the SIM. Doctors, Professors, Engineers, Engineering Colleges, Leaders and many more. But what can I do? I knew that there are some security policies can be implemented for SIM and mobile set security. But I haven’t implemented any set/SIM security with my mobile set. It is useless even if I have implemented the security over my mobile set because there are provisions to unlock the mobile set through software connected with the interfacing device.

Now my objective here is to make the lost mobile set completely useless so that pocket/mobile picker can easily be avoided. In this security control model, all the PUK no and PIN no are useless because these all numbers are provided by the telecom service provider and can easily be broken down or can use the device after reset. The main thing is the hardware identification No to be provided on each mobile set like what we provide MAC Address on each Network card for computer networking and internet. Just think that your mobile no is your IP address and mobile MAC is the built in hardware no provided on each Mobile device. There is another code provided with our SIM (Security Code). The Security Code is the main administering code for the mobile set and mobile no. both.

The newly purchased SIM (or mob. No) should be registered with operator’s security control system with the mobile set’s MAC no. (here hardware id is supposed to be a MAC of mobile set). The mobile no is supposed to be bounded with mobile MAC so that the connection/communication is only be successful when call is established with the given mobile number together with the MAC of the mobile set provided on the security control database. For every connection should check on the mobile MAC table so that the mobile number is bounded with mobile MAC during the communication. The security control database for individual mobile user might be like:

Security Database

By the use of security code, we can simply insert, update or delete the MAC no from the security database of corresponding mobile user. Hence MAC is that number which makes control over the mobile number as well as the mobile device both. If a call is attempted, before establishing the call, mobile number with corresponding Mobile MAC is checked. Every time the device should send its hardware address (MAC) to mobile switching center or it is like a firewall which should be checked before the call established. If the caller number is mismatched with the registered MAC then the system found that the mobile device is either theft or broken.

Security Check during the call (Flow Chart)

We use 48 bits MAC address in computer communication. Principally this 48-bits MAC is also more than sufficient to generate unique physical address for each mobile device (2^24= 281474976710656). Hence a telecom operator might have 281474976710656 mobile users which are more than the world’s population.

The mobile service operator, provides the SIM with security code and mobile no to the customer by registering his/her name, address, citizenship/passport no bounding the mobile number and security code. The customer’s first job is to enable the SIM with the mobile device’s MAC address. For this, customer provides the security code to insert/update his/her MAC over the security database table. We can add more than one MAC (Device) if we want to use single SIM to operate with more mobile devices with respect to time.

Hence the security Access Control List (SACL) fully control over the mobile number and mobile device as well properly. What if, the mobile device is lost?

If the mobile set is lost,
1. Provide your security code and blacklist the previous MAC (insert into blacklist database).
2. Provide your security code and update the security database with the FAKE MAC value.

Now the mobile device is completely unusable within its network. However this device can be used with another service provider with newly provided SIM. There might be several mobile operators within the country like in Nepal these are: NTC, Spice Nepal, UTL, Nepal Satellite, and Smart Telecom…that’s why any device blacklisted with NTC database can be used over Spice Network or other telecom network. However, we can’t establish a call to the network from where the device is blacklisted. It is operable only within the owner’s network. Anyone device blacklisted in one network can be made useless to other network only if we synchronize the blacklisted database i.e. frequently exchanging the blacklisted DB through Electronic Data Interchange (EDI). Controlling of mobile Device through centralized security controlled BD has several advantages:

1. Solve the problem of mobile lost (theft)
2. Telecom fraud control
These two are the major issues in telecommunication sector where we all Nepalese are facing.

48-bits MAC addressing with mobile device has added advantage for the implementation of IP-based communication through mobile set like internet and the implementation of Next Generation Network Application.

Let’s develop the standards for such implementation with mobile so as to make the security tighter in telecom network.

(This is the preliminary idea I have imagined, I am not sure whether this idea has already developed and implemented)

Sauraha-Daraudi Trip, Refreshment and Declaration

2010-02-02T10:24:00.004+05:30

The three days (Magh 15, 16 and 17) visit to Sauraha with Daraudi river, were the one most memorable days for me. We DOECE group has campaign picnic prgram to saurah, chitwan. Not only sauraha, the group of prof. teeka upreti visited daraudi river as an unplanned additional entertainment. Definitely i will write the memorable situation in my blog. Before that i will like to post the group mail posted by Dr. Jyoti Tandukar in our DOECE group regarding sauraha declaration. Lets see, Sauraha declaration will have movement or not. the copied contents as below:

Prof. Jyoti Said:
"I hope that all of you are serious about our Sauraha declaration. As a responsible professional of this society, I personally believe that we have to ensure that our voice is heard. This movement could be an important step towards that, therefore, I totally support Tika jee's proposal.

We have to discuss and decide what could be our plan of action, and what has to be our common commitment. But before everything else, we need a name and symbolic representation. I am proposing English and Nepali version for the same. Please approve or propose a better one."

Where is Nepalese IPv6 Task Force

2010-01-18T21:45:00.002+05:30

Its Nepalese bad habits that they never initiate by themselves for the innovation as well as solving of any problem within the countries. This is the scenarios from Nepalese politics to every other sector where let non-Nepalese solve our problem. Prithvi Narayan Shah said that “ NEPAL DUI(2) DHUNGA BICHKO TARULA HO”, instead our famous artist Manoj Gajurel said: “NEPAL DUI (2) TARUL BICH KO DHUNGA HO”. I really appreciate with Manoj Gajurel with this famous quotation ha ha. And it’s the reality. If we look at the policits, technology, economy, education bla blab la…everything…our side by countries is far ahead.

Technologies enter very late in Nepal. Nepalese follow the technologies only after other countries implement earlier (4/5 yrs before). This is obvious because we Nepalese are poor in every sector. Electricity, education, technology, politics but proudly to say we are very ahead in doing strike…:P. it’s my fault, it’s your fault, its his/her fault, it’s all Nepalese faults that we want to do nothing or we can’t do anything even if we try it. Might be it’s a situation or condition of Nepal that we always in dilemma.

Its been five years since I have been operating IPv6 network in Tribhuvan University Nepal under AI3/SOI-ASIA (http://soi.ioe.edu.np) project, WIDE University. The project’s major objective is sharing/transferring the knowledge Asia-wide and world-wide with the latest internet technology (IPv6 Network Infrastructure). We always talk about how to spread the technology and education within the countries through this project on every Bi-Annual Meeting. However, I am not fulfilling those what I want. I have to say “its my mistake”. First time we have implemented IPv6-Network in Nepal (2007 continuing initiating from 2005 after TU became the SOI partner) via its university research network from AI3 Project. Center for Information Technology (CIT) IOE Pulchowk campus has its IPv6-only Network where online classes are conducting almost daily via SOI (School on the Internet) project(www.soi.asia). But it remains as it is. No more extension. With my Five years working experience over IPv6 network (consists of IPv6 servers and routers), I came into some level of confidence to extend IPv6 over Nepalese backbone network. But unfortunately there is no any government backbone network I found. However there are some private practices for the research network (http://www.nren.net.np) establishment in Nepal. Almost Nepalese ISPs are directly connected with outside network. It is recommended to have government backbone network with secure gateway so that Nepal could be the transit network. Making Nepal as ICT transit point is the objective of IT-policy 2057. Are there any activities to fulfill that objective? Of course we heard the optic fiber network from Nepal<>Khasa (china). East-west optical fiber network and optical connectivity with India. These all initiated by Nepal Telecom, the leading company of Nepal. Nepal Telecom is going to implement NGN starting with this year from its network. But what about IPv6 Implementation. No problem, we can implement NGN over ipv4 network however future of the internet addressing is IPv6 where all the NGN services can only be fulfilled with new addressing mechanism.

IANA already announced the address space exhaustion (http://www.potaroo.net/tools/ipv4/index.html) with IPv4 and by 2011 there won’t be IPv4 address any more. (http://ipv6.he.net/statistics/ ,IPv4 exhaustion report). In this scenario, it is the time for Nepal to have activities for the IP issues. India, china, Pakistan ….and all other countries have already planned to move to IPv6 infrastructure with the formation of IPv6 task force. (http://ipv6forum.org.in/).

Activities of IPv6 task force India
·    Liaison with members of the national and international community to spread awareness of IPv6 in the areas of technology, policy and business.
·    Arrange summits and awareness events periodically.
·    Share new developments with the members and community, through locally hosted resources.
·    Encourage showcasing of IPv6 deployment and interoperability, including applications.
·    Identify and drive projects in IPv6 product development.
·    Promote India as a solutions provider for IPv6 services.
·    Align with the activities of the international Forum.

Pakistan IPv6 Task Force (Pkv6TF)

The Pakistan IPv6 Task Force (Pkv6TF) is dedicated to the advancement and propagation of IPv6 (Internet Protocol, version 6) in the Pakistan. Comprised of individual members, rather than corporate sponsors, the Pkv6TF mission is to provide technical leadership and innovative thought for the successful integration of IPv6 into all facets of networking and telecommunications infrastructure, present and future. Through its continued facilitation of technical and business case whitepapers, IPv6-centric conferences & seminars, IPv6 test bed and IPv6 deployment readiness guides, the Pkv6TF will strive to be the guiding force for IPv6 adoption and readiness in the Pakistan region.

In this context, it is the time for Nepal government to think about IPv6 task force. Then who is responsible on it? HLCIT or NCIT??? Right now I am currently working on NTA where I am expecting to work on ICT and Telcom QoS control. High Level Commission for Information Technology (HLCIT) is the government policy making body to enhance ICT sector of Nepal. Under HLCIT, National Information Technology Center (NITC) is the executive body. In last 2009, HLCIT chairman had briefly took suggestions with me to have IPv6 initiative in Nepal. As being an experienced IPv6 operator, I had committed with my capacity to him regarding IPv6 implementation in Nepal. I have googled about the IPv6 status in Nepal. Till this date, I could found nothing activities for IPv6 Implementation. Instead I got some commenting mails regarding the establishment of IPv6 forum and taskforce in Nepal.

Mr. Latif Ladid, Chair, European IPv6 Task Force and President, IPv6 FORUM, is quite interested to form IPv6 forum in Nepal and let help Nepal in IPv6 implementation through global IPv6 forum.

Should Nepal government say “ let ISPs migrate the network by themselves without any guideline or do whatever they want? Or lets build an IPv6 taskforce under Nepal government and include all ISPs encourage to implement IPv6 in Nepal. I hope HLCIT (as an ICT policy maker) will take short initiative as soon as possible to implement IPv6 in Nepal. International Telecommunication Union has also maintained the activity sites regarding the IPv6 (http://www.itu.int/net/ITU-T/ipv6/activities.aspx).

i hope Nepal Government will soon proceed for deployment of IPv6 in Nepal. As a concerned professional, i am always in support from my capacity to implement IPv6 in Nepal.

Double Benefit: Moment of Enjoyment and closeness with new environment

2010-01-09T19:49:00.000+05:30

I could not remember when did I join the last picnic while I was in IOE. Hummmm…yes I can remember the day at Daxinkali Picnic with IOE-DOECE Group. It was really exciting moment for me. It was the year of 2007 when I became 2 years old with my IOE job. Picnic is one of the most important moment where attendees enjoy with friends, seniors and juniors. Wake up early morning, be hurry..go to office, spent whole time in office, return back home, eat and sleep….rerun the cycle whole life.. its really being tedious and monotonous for anyone who has job. So sometimes we human beings definitely need some refreshment periodically. That’s why this picnic was organized by NTA group as an official entertainment program.

I really wanna give thanx to the organizer that this picnic gave me double benefit. I am new in NTA..the most one newcomers. Hence I was roaming with the environment when I can be familiar with whole NTA family as soon as possible. This picnic program helped me to interact with all staffs and with board members too.

Place was lakuri bhanjyang, really exciting place where I felt I am on the top of mountain. The snow falling hilly zone is quite near from the spot.

enjoyed watching the moment too. Eating, Drinking, Dancing and sharing the feelings..anyway nice moment

Ha..Ha..Ha....Bishnu..seems quite angried with sunil....and so...sunil is...ha ha ha

Nice View of Himal from Picnic Spot

Moment of Enjoyment

definitely he will won who is getting back support from our CM...:p..ha ha ha
Moment of Enjoyment

this is the way how to love the boss...ha ha

DDs and ADs of NTA!!!

My Volunteer Post Promotion!!!

2009-08-25T13:34:00.000+05:30

It is been THREE months since I have been working as System Administrator which is my volunteer post promotion just after I became Asst. Professor at IOE. I hope everybody knows the meaning of this word “volunteer”. But the pattern of my work is quite interesting. It seems neither volunteer nor professional activities. Because I felt myself that I am not working properly in my old office. Sometimes damn care but sometimes caring too. Sometimes when I got a call regarding the problems, my answers would simply be “that’s not my responsibilities” but sometimes feeling that I am not fulfilling responsibilities myself.

I have to recommend lower level staff’s leave, recommend for equipments procurement process and blab bla bla..but officially, it is not legal as its being not the scope of volunteer.

These days I got a post “System Administrator” of CIT which is my former office after I got new appointment of DOECE. I am sorry I am not handling all the works within this office as being system administrator. It is just a “kam chalau” ..Because I am just waiting system and network engineer who only can handle the responsibilities as assigned. Another problem is I don’t have time to do research on networking and system administration. This might be the cause due to my other professional engagement.

I know that I am really benefitted from this post that is only I gain from my office. It is not a simple one who got volunteer to handle whole system with its big network. Imagine why people want to do volunteer in UN, World Bank etc…..

Previously I was system engineer, now I am one level promoted to handle all technical and nontechnical administrations so called “System Administrator”. Anyway it is my big achievement.

Quite surprised!!!..There was big transition in my life during the period between last and current new post in my blog. Definitely I have to write the effect of change in my life but time ..time time……really tough to manage the time.

It’s too much: I am angry with myself

2009-05-30T12:29:00.000+05:30

Out of 24hours a day, let’s assign 6hours for sleeping. Health is wealth, so I have to sleep at least 6hrs which is necessary though not the sufficient. But remaining 18 hours is not sufficient for me. These days I am always in rush, always running out of time, running out of responsibilities, running out of contact with friends and family too. Around 6AM is my departure time and around 7PM is my arrival time in home. I am really sorry mom!!! I knew it is an added burden for you to maintain my room. My mom, you never satisfied with servant’s work, so you always involve yourself setting up all the things.

I am trying to find out my weak points in my profession. The major weak points are:
1. Never say like “NO”, “I can’t”, “Its not my Responsibility”, “I Don’t…”
I never say NO in my boss’s order though its out of the scope of my responsibility. Though I do have little knowledge I treated this like I am expert that’s why boss always order to do new things.
2. Weak Time Management but more punctual
Time management in the professional life has vital role. I always tried to finish my work in time but due to overloaded tasks I hardy catch up my time properly. Sometime punctuality may raise problem in Nepalese context. When I go to teach in private engineering college, I always have to wait students to take class. Even in any official meeting where time is fixed but always I would be the first candidate in meeting hall at the proper starting time.
3. Can’t avoid help for others.
I know that I don’t have leisure time to help others on every aspect. But whenever I am requested for the help I never say NO though it might be out of my capacity and no more time to provide to them.
4. Straightness
I never lie, I never wanna lie and always wanna be open. But its not good to be frank and open in case for Nepalese scenario..

Heyeee why don’t you maintain the website of Balkhu (www.tuexam.edu.np)? You are the system engineer.(i am mis incharge!!!)
Why is it poor the site ioe.edu.np? You are the system engineer.
Why did this wireless device not work? You are the system engineer.
Why the campus network always seems to down? You are the system engineer ( i am netwrok engineeer)
Why don’t you maintain the PCs around the labs? You are the system engineer. (i am maintenance operator)
Why don’t you solve my problem, its been 15 days since I can browse the internet but can’t open
hotmail/yahoo mail system.
Babu Ram, why is there traffic congestion in our campus network? (i am network engineer)
Babu Ram, update the dialup account of …… soon. (i am account operator)
Why don’t you provide the antivirus packages? My pc is always infected with virus.
Babu Ram, did you finish the meeting website? (i am web manager)
Babu Ram, please make the registration online soon.
Babu Ram, make invitation letter to all professors and mail them as soon as possible. (i am administrator...)

Babu Ram, why didn’t you take M.Sc. class yesterday evening?
Babu Ram sir, lab time already started, please come to lab.

BaaaBu, whats going on with World Bank Networking? Please estimate the equipments properly and submit as soon as possible.
BaaaBu, are you supervising the site continuously? Follow up the contractors and make them properly working.

Babu ji, did you finish the Networking BOQ of Bank of Kathmandu? If not when will you finish, please its already late.

Babu ji, did you finish the drawaing of networking design of all 9 stories? Please make sure that every point should be in proper position and well documented.

Babu ji, the deadling for the submission of tender documents coming near, please complete in time.

Babu Ram sir, why didn’t you come to take class of this Saturday morning?

These days, such questions always hit me. I am always interested to solve the task. But I don’t know how I am managing the tasks.

Almost spaces of my room is covered with building maps though I am not the architect or civil engineer. But until and unless I have to handle AUTOCAD properly, I need to draw manually the drawing over the hardcopy map.

AUTOCAD 2004!!!!!!! Giving me more tension, how to learn. During my bachelor degree study, I never tried to learn Autocad because I thought it was not necessary for us like computer engineers. But I realized, for professional computer engineers, should have knowledge of every packages. When I started my career in computer networking design with structured and backbone cabling, I realized myself lacking behind the use of AUTOCAD. The architect always provides me the softcofy and requested me to draft my job over there. I am feeling very difficult to play with AUTOCAD though learning slowly..its interesting.

So always work..work and work…….due to lack of time, when shall I have time for refreshment. I like game but it became far from me. Hence I am not happy with myself. So after a long period of time I hardly decided to allocate 30 minutes to write this blog. Please god, help me to avoid my weak points as soon as possible. And I am expecting more my weak points from friends, enemies, and other commentators so that I can improve myself.

In Summary: Challenging and busy year 2065 for me

2009-04-14T15:16:00.001+05:30

Life is like a sinusoidal web. Sometimes the level of happiness goes positive and sometimes goes negative. During the year of run for 2065, I found myself more professional, have to be matured and more thoughtful and taught me to come to fast decision making. Somehow I learned what the life all about more than previous year is. This might be cause of staying together with family and job only, because 2065 was my void year regarding learning.

Baisakh, the first month of 2065. I was quite busy in preparing my paper to be submitted in an International conference. I felt myself too tough in writing and finalizing the research paper. As per my interest in Computer Networking especially in IPv6 networking. I decided to write a paper from my thesis book. This was my positive work furnished properly and submitted to the conference viz. “International Conference on Electronics Commerce in the Twenty First Century” conducted by TU-Central Department of Computer Science and Information Technology. It was a joint paper with my professor Sashidhar Ram Joshi.

Nothing new happened in Jestha. Activities of life continued normally. June 10-12 (I think), presented the approved paper at soaltee crown plaza, kathmandu. I had written one blog about the experience of presenting papers in an international conference. Shrawan, most successful month for me. I was appointed as Executive Committee member for the BE entrance exam management of IOE Pulchowk Campus. Handling software for BE/Diploma was not an easy tasks. I had created my own online software package for Diploma and BE result management of processing. I became quite happy that my software performed well without any problem. Admit Card Processing, Result Processing were challenging and interesting experience. Mean while, I got a chance to become Network Specialist at World Bank Office, Kathmandu Nepal. It was my great opportunity to handle all the Networking section project there. Tender documents preparation, Structured Cabling design, Backbone Cabling design. Supervising the site setup, installation and verification. There was a little misunderstanding about to handle the responsibilities on this project. Worldbank office at Nepal has extended its office which requires perfect networking as well was want to replace old cabling (CAT 5) of the existing space. All the networking for new space was already designed by IM Tamrakar (Electrical Expert). I got the responsibility to handle Backbone network and CAT-6 Networking for old space. The months (shrawan, Bhadra, Ashwin) were quite tough for me because I had to finish the semester courses, involvement in Entrance Exam of IOE and Worldbank office. Finally the World Bank office project started from November. The project duration extended due to Nepal’s political circumstances as well and the experts of World Bank were not satisfied with the work furnished by the contractor right now. We consultants are the professionals. Every work done should be finished in a professional manner where contractor’s carelessness gives rise to bad professionalism too. I don’t think that I can extend consultancy with those contractors who don’t have professional experience.

My office job, it is my continuous life. Ashoj was my month where I decided to have motorbike which is compulsory to avoid the valley’s traffic jam but it was my unfortunate events that I fail two times to achieve bike liscence. Mangshir, the month when I got a chance to participate in an online education project Meeting so called AI3/SOI-ASIA Fall Meeting in Manila Philippines. This was my second country visiting abroad. Philippines is quite nice and developed country. Unfortunately, my return flight was interrupted due to political strike in Thailand. Additionally, I visited Dubai and Quatar when I return back from Philippines.

On Magh, Campus added me one more responsibility to handle the technical system for e-Voting at IOE Pulchowk Campus. I became the committee member for IOE FSU election. Handling all the system for election was quite challenging for the current political situation. Though the election was successfully completed with peaceful environment. I am surprised that my technical design work to conduct e-Voting was perfect. I put my all design work and necessary information for the election in the web http://election.ioe.edu.np. From Falgun, now I got another big responsibility to conduct operator’s meeting in Kathmandu. Joint effort in the project is much better than single effort. These days I am a bit in trouble that I don’t have sufficient human resources to handle the meeting properly. I hope every concerned people may show seriousness and care on this regard. Hence overall, I learned from year 2065 that: what is professionalism?, What are my responsibilities? How to take better decision? I hope I need to have DSS for me. I don’t like those careless guys who can’t handle his/her responsibilities properly and blame others for all faults to safe from his/her own responsibilities.

FINALLY, HAPPY NEW YEAR-2065 TO MY ALL WELL WISHERS/CARETAKERS. HOPE THE NEW YEAR-2066 WARNS ME ON MY EVERY NEGATIVE ACTIVITIES AND REWARDS ME FOR MY EXCELLENCY.

Software Track: Cyber Mall Automation System

2009-03-01T16:18:00.002+05:30

writing a program for a programmer is not big task as compared with designing front end and backend. Before that, analysis to have perfect output is the major one. without having depth analysis, one cant design the system. Further without having perfect design, coding is not possible. While i was in second year at my Bachelor study, i always tried to have code first and get output then others like keeping focus on analysis and design. But i realized the importance of analysis and design in my final year project. Our motto was to get the product completely implementable for the competitive market. Though somehow, we were successful but limited time could not allow us to get the perfect outcome.

Anyway i was quite satisfied with my work in my project. I was always worried about the project because my other partners were more relaxing. I also felt that leading in a project is not an easy task. Analyze the system, design the system, coding, reporting ...means like following software development life cycle properly. But who can handle which part..proper work division in a group may not lead to desired output.

Here i want to describe briefly about what my project was. the project was entitled "Cyber Mall Automation System". In Kathmandu Valley, there are lots of cyber cafes but no one Cyber was found to be automated. Time manipulation, bill generation were not the only activities out project captured. This project was designed with border concept that a cyber cafe may provide cafe service as well as the necessary stationery for the internet users. A cyber may have pre-registered users who can balance for month, year or even lifetime so that every time its not necessary for him/her to pay for the service. Cafe administration system should have to deduce the price automatically for the registered users as well. No problem, one can pay on the spot for the service.

We already have computers in networking. Definitely there should be a gateway server on its Cyber LAN. Hence to implement a software system for allCcyber activities with cafe services requires no more resource addition. Just run the software on its LAN as a client-server environment. Based upon this concept, the project was formulated. the major facilities of the package are:

1. client-server based.
2. calculate the time based on processor's clock tick for the internet users.
3. realtime cafe service as per the order by the client from his/her desk.
4. Advance Payment system for the frequent internet users (once a users is registered, he can access the cyer facilities until his balance donto cross the minimum threshold)
5. realtime bill generation.
6. daily/monthly/yearly report generation for managerial action.
7. Remote monitoring of the client machine (shutdown client, lock/unlock client etc...)
and many more.

The Concept:
1. the server keeps status of its all clients in the network by polling every minutes.
2. server database contains clients_PC database, Items Inventory Lists, internet users database.
3. server keeps log of every users conenction and order activities.
4. server gives alarm based on clients orders/requests.
5. client could not access internet without providing username/password.
6. registered users and guest users are treated separately to maintain the necessary information.
7. server can shutdown the remote PCs at time at the office close time.

The figure on the left shows the collecting hosts information just after running the server process. When an operator logs into the server, it starts finding out the live clients and listed its status. When any user logs into the client for the internet access, it is responded to server and listed on the same session table which has client host, status (power on/off), internet session, logged in username, type of
user(guess/registered), and time span.

The server databse must maintan the host information in its LAN. When new PC is connected to LAN, the name and IP address for that PC needs to be specified and registered into the server databse. Client PC never sends client name and client IP to server. so first its name/IP should be specified in the server databse and client package have to be installed on the new client.

The service provider not only provide the internet but also provide cafe service. when internet users want to have snacks, he can place an order immediately. Hence the server database maintains items inventory with its rates and availability information for that day.

It is remote control window in server side. this window lists all the live PC on the LAN. Just before closing the Cyber, the administrator shutdown all PC from server control. in addition, if any one internet users found doing fraud, admin can lock the clinet machine immediately.

For any MIS and automated system, Report is the most. It helps to analyze to do further decision and actions.

This is client's welcome screen. iI there is server failure, client may connect to another server choosing from the list of servers. Without connecting to server, no one client can enter into the system. All the special keys are disabled for security purpose.

After client logged into the client PC, his time starts the cliet only send the login time and logout time to server. But for cliet's reference, it is continuously displays on the clinet side.

The order placement window. the item list on the table shows the available items for that moment. Client must first put order adding items on his/her basket and finally order as per his/her requirements.

Hence, this software has lots of features which i cant explain in detail all about within this blog. We did our much effort to make the system user friendly and attractive too as well as bug free. It can be implemented to anywhere like not only to Cyber cafes but also to a departmental store which supplies goods where we can avoid internet billing rather we may focus on items billing.

University Education in Nepal!! Where teachers follow student’s schedule

2009-02-18T12:00:00.000+05:30

It is been five years since I have been teaching several universities of Nepal after my graduation. From my experience, I am trying to compare different university education system and learning environment.

Acme Engineering College under Purbanchal University from where I had started my first career in teaching. Definitely the environment of Acme was quite beautiful. Teacher’s dedication, student’s discipline and friendly environment was the major assets of Acme. Even though I had to leave Acme to uplift and hence entered into Pulchowk Campus under Tribhuvan University. More beautiful environment, respectful teachers-students relationship, competitive education, dedicated and well disciplined students but somehow careless teachers and seeking environment. Apex College under Pokhara University, was another beautiful college with impressive environment. I found friendly and respectful environment with somehow dedicated and impressive students.

During these run, I looked back a college where I felt very frosted with the situation where the institution is completely under control of students. No more respectful environment, no more discipline, no more dedication, no more care about the institution and ownself. I can’t imagine how would be the environment where teachers have to follow student’s schedule. Students control teaching learning process. in the ense, every decision is not possible without approval from students. Seems students themselves have rights to recruit/filter teacher, set the questions, answer the questions and check the answer papers and get full marks. Dull students and dirty environment.

What is the cause behind this? Definitely politics…the major issue for those small minded who want to achieve the university degree without knowledge. Definitely there are some students group well aware with their education but have to suppress behind ………….though politics is necessary for student education, its not a politics but a criminal activities i realized.

Nepal government or University Grant Commission has to level the university education to maintain the quality to identify real products and fake products. So that there will be no problem for Nepalse students to accredit in foreign universities.

Software Track - Object Oriented Programming (3-D visualization of Complex Poynomial)

2009-01-25T16:31:00.000+05:30

I just looked back to my project developed as subject project while studying BE Computer Engineering@IOE. Among the different types of programming, I like Object Oriented Programming specially JAVA due to its robustness, architectural independence, parallel processing (thread), and other properties of OOPs.

Computer Graphics, one of the interesting subjects of study. Rajendra Dev Adhikari (Currently telecom engineer), was the subject teacher encouraged us to develop project in graphics. We had to implement Gaurad shading and other necessary algorithms if possible.

Myself (Babu Ram Dawadi) with my roommate Arun Parajuli in IOE hostel decided to draw complex polynomial using Hornor’s Method (studied in Numerical Method). Arun Parajuli was quite perfect in JAVA multithreading. Hence our effort came into realization that we perfectly developed a project combining graphics algorithm and Numerical Method Algorithm. The project was developed in JAVA Swing. If you supply coefficients of a polynomial, then the program shows the 3-D plot like shown below.

License No. 06-155450, achieved with my 3rd attempt

2009-01-04T17:41:00.000+05:30

Perfect Cyclist can acquire license of Motorbike in Nepal, How?

During my intermediate level, my roommate (class mate also) purchased one new brand cycle. From that cycle, my travelling life had been started. But for the whole study time of BE and ME, I used to stay Pulchowk Campus hostel. That’s why no need to travel far away around the valley because my job and study was on the same campus. Hence hostel life, campus life and job life within the premise of Pulchowk. But after completing my M. Sc. Degree, I had to leave hostel and started my family life instead of study life.

World Bank office (network specialist), Acme Engineering College (E-Commerce for M. Sc. Stds), Apex College (Computer Network), Kantipur Engg. College (Geographic Information System), Advance Engg. College (Data Warehousing & Data Mining), National Engg. College (Advance Network with IPv6), DNET (IT Consultant) and Pulchowk Campus (System Engineering, Full Time Faculty). Almost time, I engaged in travelling. Uffs..Valley’s Traffic Condition is so worst that it may take an hour to travel every 5KMs.

Hence a compulsion for me to purchase motorbike. It is not my hobby but it is compulsory for me to use bike for travelling. But without license, biking is not good within this over traffic road. After one month practice, I appeared on the written exam for the license. The written exam is so easy; it is not like any semester course examination. But I failed the 1st trail. It was urgent for me to have license anyhow. I didn’t want to take risk second time that I need license even if I fail the trail. The only way is to use brokers to achieve but these days after the staffs of transportation department got suspended, it is difficult to achieve license without trail pass. I tried to use broker anyway. Broker fully convinced me that he can manage license for me even if I fail the trial. After the discussion, finally it was fixed to pay Rs 3000.

I appeared on the second written examination and subjected to trial. Brokers are so intelligent. He just put me in risk. He provided me one scooty and got full practice. What his tactic was, if I pass the trial he would consume whole 3K rupees without paying to officer otherwise describe some situation of not to achieve license. It was really bad lock for me that I failed the second trial. Eventhough I hopped to get license because I committed to pay Rs 3K to broker. But he described with the situation that I could not achieve the license (the day when I appeared on the trial exam was checking day from upper level officer of government so can’t pay for the license, he said..ha ha ha). Ohhh noooo..i got myself harassed, I had to reappear the exam. The broker again convinced me that this time he could fit the strong channel to get license even if I fail again. But I knew that, without trial pass, impossible to achieve.

I appeared on the third examination. Friends suggested me to use RX100 bike for the trial that any one broker can provide. But have to pay 1500 to 2K to broker to use that bike for the trial. Anyway, I decided to use that CD 100 (same like RX) for my 3rd trial. Amazing, it is not a bike but it is like a cycle. Once the bike has been started, no need to accelerate. Bike moves ahead itself in gear one without using clutch/accelerator with constant speed. My job was just turn the handle during mode. Wauuu!!!! its a simple cycle. Hence if one is a perfect cyclist, he/she could easily pass the trial using CD100 old bike from broker. i simply passed the trial from that bike. Thanks god!! I achieved the license. The direct way is to pay 3K to get license even if one fail the exam but its not possible these days (it is good for this step to control corruption). So use of RX from broker is the indirect way to achieve license. If government really wants to control corruption, it is necessary that everyone have to appear on the trial with the common standard bike that government should provide during the trial.

CD100 Bike for Trial pass

Broker’s Strategy: in the broker’s trial practice center, they provide scooty for the practice. In the very beginning, we can’t cross all pole because we need to set our hand with scooty. But they try to make us harass (they said, “seems you can’t pass the trial. So if you provide Rs 2000, we request officers to increase the gap of pole and make you conform to pass or you have to provide Rs 4000 if you want license even if you fail the trial”) and hence make a commitment to pay. Bakbasss….all bakbasss…brokers can do nothing and keep in mind that you never get license without trial pass. So I would like to request all examinees that just pay Rs 500 for the use of their bike and get practice then pass the exam.

Suggestion to Government: once I passed the written exam and failed the trial, why should I appear the written exam again for the next trial? I think it is not a good practice to reappear on the written examination. Once I fail the trial, just pay Rs 200 as tax again and get slip for the next trial. From my teaching/learning experience, once a student passed the semester course and failed the practical exam, he/she would only fail in practical exam and so have to reappear on the practical exam only, no need to reappear on the theory exam of that subject of which he/she fail in practical.

AAA for Wired and Wireless Campus Area Internet Users @IOE Pulchowk

2008-12-17T11:15:00.000+05:30

Center for Information Technology of IOE Pulchowk campus has been managing Internet Users over WINNT Domain. It has been 4 years since I have been working as system/network administrator managing different servers of IOE.EDU.NP domain and SOI System under WIDE Project. During this run, several improvement have been done like IOE Mail, bandwidth management, power management, network management and hardware update etc.. But it’s a universal truth that clients never satisfy with the service.

As a consequence, I tried to remove all the domain controllers with old P2 Dell server and replace the authentication through radius users over Quad Core 2Ghz Dell Server. I found radius authentication the best one solution for wired/wireless and dialup users. So that through a single database server can control all kinds of user’s authentication though LDAP is also another solution. IOE Pulchowk has more than 2000 users on its LAN, so it’s not the easy task to maintain more than 1500 machines enabled with internet. Virtual LANs on the central backbone switch, two Transparent Proxies, and two Radius servers enabled the system a bit manageable.
Chillispot is a wireless captive portal mostly suitable on wireless internet, though it can be used in wired LAN (UAM technique). I designed to have a concept of utilizing chillispot on wired as well as wireless LAN. Chilli-Radius Authentication with appropriate firewall and bandwidth control is the current implementation as new authentication system in IOE Pulchowk Campus. But performance is another major issue whether the new system might have shown improvement in internet access or not.
The central authentication system is supposed to have some benefits like:
•Users can be captured with their MAC/IP address
•MAC authentication can be implemented
•Fraud users can be identified
•Users with unnecessary site access can be easily traced.
•All the users request is passed through transparent proxy: performance is supposed to be improved
•Public IP block Saved (private Class B IP addressing has been implemented)
•Web based password change option

There is still difficulty in wireless user’s authentication in case of using wireless routers. Normal Wireless router doesn’t have authentication within itself. But due to over traffic chilli and firewall process seems not working properly. Symptoms of frequent connectivity breakdown may need more research and test.

authentication system

The basic authentication and internet system is as follows:
•When a client browse the internet, the gateway servers running chilli and proxy provides authentication page to clients.
•Client supply the username and password which is forwarded to radius servers for the users validation.
•Radius server replies with the validation information to chilli, then the users are authenticated and the subsequent request of users would be forwarded to transparent proxy.
•Users can be seen online until he/she logged out.

My First Attempt: Paper Presentation in an International Conference & IT Park Visit

2008-06-16T11:22:00.000+05:30

“International Conference on Electronic Commerce in the 21^st Century” was the main title of the conference held in June 2 to 4at Soaltee Crown Plaza, Kathmandu Nepal. When I appeared in SIGCOMM 2007 conference at Kyoto Japan, I was really surprised with the environment. I hadn’t had expected that environment on this conference though I was curious about the situation because I had to present my paper there. What if I could not answer expert’s questions!! :O. I was a bit afraid as the hall was full of foreigner and locals. My English is not good so far though I had already prepared somehow to cover up my 30mins presentation time.

The organizer had mistakes in formatting my paper which could easily be pointed out from the wrong mail address and wrong picture placement. Any way I felt really comfortable with presentation and as per my knowledge, I easily tackled the questions at the end.

Australian professor Kuzic was a bit funny and impressive. Almost Asian guys especially Indians were presenting their paper just reading slides. Kuzic commented it out that just to explain what we would understand...no need to read line by line. Another professor Leon from Luxemburg wanted to start his session with European Style (keep the audiences relaxed ...like provide them beer, whisky…). Sometimes the hall was disturbed with mobile ring during middle of the presentation…ha ha...it’s a Nepalese Style.

The last day of the conference was already planned for foreigner to visit to IT Park. By the way, I had never got a chance to visit IT park of Nepal which was located alone at Banepa. This was my opportunity having trip with foreign professors to IT Park. The member secretary and full time member of HLCIT briefly described about the environment and technology currently implemented in IT Park. One thing what they focused with proudly was about finger print verification to permit into the room. Ha ha ha...it was already old and nothing for foreigner. Hence Australian professor frankly commented that not to be proud of our work but be focused what we could do and approached with vision to Indian and Chinese which are the two major IT industries of the world. I appreciated his comment.

Discussion meeting at IT-Park, Banepa

Group photo on the IT-Park premise

The trip to Bhaktapur Durbar Square was also quite interesting. I had to visit friends in the evening for software development and outsourcing plan. So I just separated from the group who had next plan to visit to Pashupati around 5:15PM from Quoteshwor. Thanks much to Dr. Tank Dhamala (Head, TU Central Department of Computer Science) for such a nice trip and for the successful completion of the conference.

Guest Lecture on “Introduction to IPv6 Networking” to TU M.Sc. Computer Science Students @IOE

2008-05-26T17:07:00.000+05:30

Last Friday, Asst. Prof. Jivan Kumar Pant sir discussed with me about to give one lecture on IPv6 Networking and demonstration of IOE Pulchowk campus’s System/Network. As per the discussion the class had been set on Sunday morning at 7:30AM. I was in hurry up at that time preparing slides for conference presentation. I had to meet prof. sashi sir anyhow as soon as possible. My work load was just increased by the guest lecture too. Whole day on Saturday I started preparing slides for guest lecturing and planned for system/network demonstration too.

I was a bit felt uneasy to have lecture with M. Sc. Computer Science Students though I am teaching e-Commerce to masters student at Acme Engineering College. But it’s a way to disseminate knowledge. Teaching learning process doesn’t indicate senior/junior. I thought my slides were too summarized. The presentation just covered the introduction, addressing mechanism, current scenario of IPv6 in the world and transition mechanisms. I had prepared some IPv6 practical activities like unicast and multicast routing in my laptop with VMWare server.

When the day came, i had started my lecture and during the time, I surprised that the professor of computer network at TU central department of computer science himself was listening my lecture sitting behind the chair with students. I felt a bit happy that the way I delivered my lecture was more than sufficient for students. IPv6 is still new in Nepal though other countries have implemented on some network. The resource to study about IPv6 is really limited in Nepal. That’s why professor himself was expecting some input about IPv6 from me. When I did my research thesis with IPv6 Networking, my confidence toward IPv6 is drastically increased and the practical networking environment with IOE IPv6 network really makes me more confident.

After completing the lecture, professor and students both were seems happy with the contents what I delivered and it really felt me happy. With my co-worker Manish Singh, The demonstration of both IPv4 and IPv6 network was successfully completed. I hope this lecture and demonstration will help students encouraged towards networking and system administration.

Why did I share this feeling with my blog?? Really I did one mistake in my presentation slides. I had included one slide which compared header structure of IPv4 and IPv6 protocol. When I just reviewed my slides today, the version field for IPv4 must specify 4 and for IPv6 must be 6. But on both header structure, 4 was indicated. Hassssssssssssssss…what a mistake. Sorry students and professor, u didn’t indicate my mistake. Hope you correct that mistake.

Do You Like Piano?? Make your Computer Keyboard a Piano

2008-05-05T12:49:00.000+05:30

There is no one in this world who hates music. Piano is a typical Musical Instrument which is frequently used to play while we become offset or we come into tension. Hence this device is used to play for peacefulness and coolness.

During my Masters study, I have developed a software package using Visual Basic as a project categorized under Multimedia which was an elective subject. Teacher suggested us to create a group and build a project which must cover objective of what we were studying in Multimedia Subject. Responsibility went to me to create a project anyhow. I thought to build a piano which is helpful to everyone because anybody if he has a computer, he could simulate the principle of Piano by his computer keyboard.

Some of the keys of computer keyboard are taken as piano keys. It is similar like real piano. If you are perfect in playing a piano, I confirmed that you will really enjoy with this software. Let me give you tips about how to install and play:

You can download a pianosetup.doc and serialkey.txt (key: 1111111111) from the following link:

http://baburamdawadi.tripod.com/project/pianosetup.doc

http://baburamdawadi.tripod.com/project/serialkey.txt

(alternetive technique to download: copy these links to Browser's address bar and enter, if you could not download directly)

after download is complete, first rename the pianosetup.doc file to pianosetup.exe (you can run that file only after renaming to pianosetup.exe)

Just run the setup file and supply serial key what I have provided with.

After installation is complete, go to program file>>Easy Piano>> Projectmultimedia

You can see the following main screen and choose tools>>Piano

And start playing (note* your speakers connected to your computer must be working)

Enjoy Piano!!!!!!! ;)

From NGO-Profile to DNF-Profile to DNET-Profile

2008-04-08T12:48:00.001+05:30

When I was working as lecturer in Acme Engg. College, I became so tedious in teaching. Though teaching is a nice job which improves our level of confidence in mass communication as well as enhances our knowledge what we studied in B.E.

I know I am computer engineer. I thought my job must be either software programming or system/network administration in parallel with teaching. Programming only is also a tedious job (continuous programming>> monotonous).

During these teaching periods, I roamed for programming job after 2PM onwards after finishing morning shift class on the college. I like database programming. One of my friends, coworker at Acme proposed me for part time program at Compro Computers Pvt. Ltd. Hence my part-time programming life started since February 2006. The first project was Finance Model 1.0 developed for NGO-Federation of Nepal. It was an accounting package in replace of quickbooks (famous accounting software). I was afraid how could I generate balance sheet, laser, trial balance, Journal Vourcher etc…etc…though I programmed until 9PM night daily with the help of Auditor on the side.

During this programming period, I got a chance to meet mercantile programmer and we developed that first software as a joint effort. My inspiring friend Prabhat, IT manager of NGO-Federation, helped me a lot and taught me about firing trigger and writing procedure in MS-SQL Server. Due to this hard work, I became the system architect for the next project called Prime Minister Office Project (PMO). During the PMO project development, our team started the project enthusiastically from the beginning at Prime Minister’s office at singadurbar (interview,DB design….there was vice chair person Kirtinidihi Bist in Prime Minister’s post). The time was the time when king gyanendra seized the country and ruled by himself. We became unlucky that the project was closed due to country’s political instability and king’s over enthusiasm (I hate politics).

After that I became the IT-Consultant of Ngo-Federation when IT manager of NGO-Federation went for abroad study. During the consultancy I handled the entire project running on NGO with NGO-Profile which was developed on MS-SQL Server, Crystal Report, and ASP with Nepali Unicode format. After successful completion as IT consultant in NGO-Federation, I got a second contract on Dalit NGO Federation of Nepal (DNF) to create profile of Dalit NGOs. It is really interesting to program in ASP/MS-SQL server with Nepali Unicode as front end. Hence I developed data entry and analysis for DNF-Profile. Some of the snapshots are:

Data entry form for DNF-Profile

Record Search form for DNF-Profile

Data in Unicode format, in SQL Server

From that Unicode programming, my confidence level towards programming increased more. I just used these templates and created IOE Entrance Management System too. Now I am writing program for DNET-Profile (Development Network Pvt. Ltd.) using the ASP and MS-SQL. Interaction with the data entry operators, writing code, refining the wrong entry makes me quite sharp with more experiences in software developing. Some snapshots from this DNET-Profile:

Data Entry Form

Record Update Form

Database of DNET-Profile

IT-Consultancy enables us to be social, interactive and forwarding in the IT field…….this is just my way towards creating profile on NGOs/Consultancy Offices

Experience: AI3 Bridge Configuration & troubleshooting

2008-02-10T15:12:00.000+05:30

Last time the satellite transmission station for TU had just been shifted from AIT to SFC Japan. The major steps to be done for successful switchover was checking the satellite signal Eb/No. and changing the route configuration on FreeBSD router (our BDL gateway). What I had to do was just change configuration on serial interface of AI3 Bridge.

I got a bit trouble regarding the bridge configuration because I hadn’t have access to AI3 Bridge. Someone else had already set password of our SOI Bridge. No problem, I just reset the bridge (CISCO 1700 series router) password and kept backup of all bridge configuration. The bridge has two interfaces (fastethernet0>>LAN interface and serial0>>satellite interface). I just changed the configuration on serial interface like this (which is given by Husni-san from SFC)

interface Serial0
description satellite
no ip address
no ip route-cache
no ip mroute-cache
no keepalive
no fair-queue
ignore-dcd
serial restart-delay 0
bridge-group 1
bridge-group 1 spanning-disabled
hold-queue 16 out

By the way, this configuration didn’t work. I couldn’t see neighboring bridge. I used the command “show bridge” and “show cdp neighbor”. Both commands displays nothing on the hyperterminal. But the magic part was: all signal status were up with serial0 interface.

DCD=up DSR=up DTR=up RTS=up CTS=up.

I just roamed and wait response from Husni-san. Husni conformed that the problem should be on link. Finally Abazh and Me started troubleshooting online over the link. As per the suggestion from Abazh-san, I just removed the ignore-dcd (Data Carrier Detect) and no keepalive line from the configuration. Then it works ha ha ha…. Due to this problem TU-SFC connectivity was down more than a week. Hence, it indicates that I must have more experiences regarding bridge configuration (what each line of configuration do?).

Memory: From My Japan Diary

When I got back from Japan on 22 October, I became too much busy in writing my thesis. I found that research is really tough. I already planned to complete my thesis until April. But my supervisor is really an inspiring person for me. Thanks to Purushottam sir, my office director for your encouragement to complete my thesis. Due to that I successfully defended my midterm. I am waiting for my Final defense. I am still in struggle to finalize my thesis. During this time, I felt I have to write something about my remembrance on my blog.
During my three months stay in Japan, I had gained a lot of experience about the technology, culture, education etc... I felt something differences with me after returning back from Japan. First difference is my picture. Here I just compared my own picture just after arrival in Japan and just before departure from Japan.

Arrival

Departure

These two picture clearly told that I became more thinner (but I felt, I became stronger and no more change in weight...as it is but these pictures were taken from different camera).
During my stay, I had continued writing my diary. At my final presentation, I also committed that I would complete my Japan Diary and will send one copy to SFC room. But due to my thesis and other official works, I am still unable to complete my diary yet. Though, I want to copy some memorable notes from my diary on my blog.
From the Abstract……..Study is the main part of my stay in Japan; in addition to this I had some fun with Japanese peoples and cultures which is a necessary part for a foreigner. And I also became lucky that I got chance to be in Kyoto city which is the beautiful ancient city of Japan with world’s big conference named SIGCOMM2007 and Mozilla 24hr Event in Tokyo……………………..

July 25 Wednesday to 29 Saturday (first week)
It was my first time going to abroad. As Nepal is a developing country, I don’t have much more idea to be familiar with machine. I heard that Japan is a well developed country. I am one of the poor family members of Nepal. So I become little afraid that how could I handle freeze, washing machine, microwave oven etc…
……….I dropped on Narita airport around 7:30PM JST, after having custom check, I caught limousine bus to Yokohama terminal where I met funya-san and after thirty minutes we welcomed Mr. Raden Arif from Indonesia. We directly came to campus. i was really excited with the campus environment, its furnishing and lab setup……

July 30 to august 4 (2^nd week)
We had to conduct one day IPv6 only workshop for forty-three participants between July 31^st to October 16. Abazh guided us to handle the workshop properly. Handling the Virtual Machine and during the workshop was quite interesting like watching user’s activities and suggested during mistakes……
……On the Saturday, we went to Akihabara to purchase camera and laptop. Me, Abazh, Arif and another Indonesian friend, Dedy went to Akihabara. First I really surprised by seeing the big train terminal. We reached Akihabara changing train on Yokohama and Shinagawa. Ohhh another big city, full of electronic gadgets. We all were foreigner, so sometimes we lost inside Akihabara and finally we got the shop for my camera. I had already set my mind to purchase Finepix S6000 FD model by FujiFilm Company……

August 5 to august 18 (3^{rd &}4^th week)
On these two weeks, I just tried to learn Japanese language myself. But I felt that the katakana as well as hiragana scripts are not so complex but kanji symbols were found to be complex to understand…… I had travelers check of American express. I hadn’t known about how to change that check. I tried to get idea about it by funya and kotaro. They suggested me to goto banks around Shonandai. But it would be difficult for me to find bank on shonandai………
…..Some days before while we were in Shonandai where we went there just for shopping, I saw an office named Softbank. I just thought in mind that “ohhh this is the bank which might change my money”. On the following day, SFC was closed due to special occasion. I grabbed that office time and went to Shonandai by myself, entered into that office and requested for money exchange by showing the travelers check. Ha ha ha.they laughed and just got surprised. Suddenly one officer (she was a gal) typed something in her computer and wrote a sentence in a paper that “it is not a bank here”. Might be she just translated her Japanese language into English and wrote to me. Ohhhh..i laughed then..ha ha……

August 26 to September 1 (6^th week)
We two (Arif and me) had to come to Kyoto by bullet train on Sunday, 26^th august. We were somehow afraid about whether we loss inside the transit, what could we do?? By the way, it was so easy to reach to the Kyoto city. Bullet train (NOZOMI-SHINKANSEN)!!! 300Km/hr, Wowww I cant imagine how Japanese build such a system/technology…….
… I am very much thankful to Keiko-san for such a nice opportunity to appear on this world’s top conference related to computer network. During this 5 days conference I met 3 Microsoft Researchers, FreeBSD Developer, CISCO managers and professors form different universities. By the way I became lucky that I got mail-id from almost all presenters. This is my big achievement and experience about to participate in such a conference and acquiring latest information about network/routing from IETF members, Microsoft researchers and professors. What I found that it is really incomparable about the learning technique of Nepal with other countries……
Preparation for the Mozilla 24hr events on Mita campus Tokyo
We were already informed by Funya that we had to support in the Mozilla event. So our major responsibilities were

to create 5 minutes cultural video
to control VIC/RAT of all SOI-ASIA partners and
other technical as well as management support for the event

On 8^th September, Abazh, Arif, Funya and me went to Akihabara city to take some videos. Travelling along the city on that day was quite interesting; we took several videos and pictures and entered into a café for the coffee break……

September 16 to September 22 (9^th week)
There was problem in TU-RR as it was already notified by my staff at TU. But due to lack of time I was unable to give him time and also the time to meet him was not matching…. The problem was quite magic that the downstream interface of RR was not working. I requested him to send the rc.conf file through mail…. Then I suspected that there might be problem in IPv4 address assignment line in rc.conf file. Wauuu I found that there was a big mistake (typo error) on that line. I found the line as:
Ifconfig_fxp1="inet 202.249.24.209 netmask 255.255.255.248"

But it should be:

ifconfig_fxp1="inet 202.249.24.209 netmask 255.255.255.248"

The letter “I” became capital during typing.

Oct. 7 to oct 13 (12^th week)
On Sunday, we four interns went to Akihabara to purchase some electronic goods. This is my 3^rd visit to Akihabara where I purchased watch, camera and USB HDD for my laptop…….As it couldnot find booting information for OS so stuck after loading BIOS. I got tension..ufff I had several packages intalled on my note, specially I was analyzing VMware, what could I do?? Any way I couldnot recover my note and finally I installed fress XP and reinstalled my all necessary packages on Monday……

Oct 14 to Oct 21 (13th week, last)
Now I entered into last week of my three months internship period. This week was a buffer week for me to be prepared for final presentation together with problem analysis of VMware………. I had to reduce the slides drastically to not more than 40 slides. By the way, on Wednesday, my supervisor Abazh suggested me to present only the additional task and experiences. Thanks god! I prepared slides of my additional task and three months experiences on Japan…..

……Monday morning, my time to left Japan came. I left Leo-Palace on 8AM saying bye bye to Japan and caught the train to reach to Yokohama and got back to my country around 5PM from Narita Airport by Thai Airways successfully.

Hindu’s Live function: one week ceremony (SAPTAHA) in Vanasthali Ekaltar

2007-11-03T20:26:00.000+05:30

its about one and half week I returned back from Japan but due to office work load I were so hanged up. By the way, near in my home at vanasthali, a new temple has been established and people of that zone are conducting one week special ceremony so called “Hindu Maha Yegya”. I spent my half day on that ceremony and captured several photos of that special function. This program is specially dedicated to hindus where peoples gather there and listen speech by pandit (who described all about puran). We know the book of muslim is Kuran, Buddha is Tripitak and cristian is Byble. Specially elder people above 50 years old and married women like listening this program. I felt very interesting by today’s program as its musical and so exciting. Though I am hindu, I don’t like such kind of program, in the sense that it’s a kind of superstition. The pandit try to spread out things written inside puran but I felt almost all written inside this book is superstition but today from his lecture I found some scientific reason also and I felt that its 1800 years old book (puran) which describeed logical and technological things as well. Lets see some snapshots of this ceremony.

Asian Night: one more beautiful party with special foods

2007-10-25T12:55:00.000+05:30

20th October 2007, almost at the end of my internship period in SFC. This night is really more interesting for me. Thai foods, Myanmar foods, Nepalese Foods, Indonesian Foods, Japanese Foods and American Foods..wauuuu what a great combinations. The main objective of Asian Night is a food party in which everybody has to prepare their own food on the spot. This food party is specially dedicated for interns who have to make food of their own country.

We were four interns at that time. Ni from Thailand, chaw from Myanmar, Arif from Indonesia and Me (Dawadi) from Nepal with SFC staffs and professors. We made our own country foods. Previously I was wonder about how to make Nepalese food. Actually I didn’t know the special Nepalese food but I had some Nepalese recipe (Nepalese rice, meat masala, curry masala, and daal). I declared to make Nepalese rice, chicken curry potato salad (aalu ko achar) and almond bara. I was not perfect about cooking though I have more than 3 years cooking experience but I don’t have any experience to make special Nepalese food. Any way I prepared food by Nepalese style. I tested all foods of Thailand, Myanmar, Indonesia, American and Japanese. I liked foods from each country. This is a kind of good experience about sharing culture related with food by different countries. It was almost 10PM night. We returned back Leo-palace by car with Haruhito-san. Let us see some snapshots of different country’s food:

My important moment: I got certificate of my three months internship periods. Prof. Dr. Keiko Okawa and Prof. Dr. Jun Murai provided me that certificate with blessing. Thank you very much Profesors. I will do my best towards your dreams.

At the end of my internship period: Final Presentation in SFC

2007-10-20T21:33:00.000+05:30

Ohhh..i am in the last stage of my three months internship period in SFC. No more time it takes to pass the time. I completed my three months learning in Murai-LAB, Japan. Our final presentation was set on Thursday 1PM sharp. On this week I was almost in hurry to prepare my final presentation. Almost time, I thought about how to summarize my three months study within 20 Minutes. Just the day before we visited KDDI NOC (Network Operation Center) where the professor at university of Tokyo demonstrated us security center of Japan, NTT network and WIDE Network. We first visited university of Tokyo and after meeting professor kato, he started demonstrating the network operation of Tokyo University. I am really impressed by such a great professor about his knowledge to operate network as well as his nice demonstrating style.

I had never ever imagined that how the security system could be implemented. By this visit, I realized that it’s a great job and great way to control and secure the data. You may have three layers of security to reach to the gear. I don’t want explain any more about this because it’s a secret about security implemented by Japanese. It’s not under my rights to explain this.

I come to my final presentation now. On Wednesday evening, my supervisor advised me to reduce to slides drastically and made me to explain just about my additional task. I started summarizing my slides of my additional task only. It was being very hard for me to reduce the slides..because I have to reduce it from 93 to 25 only. Any way I reduced all the make the complete slides which included my experiences also. It was about 46 slides to be completed on 20 minutes..might be impossible but I just tried to show slides fast. On this final day of my learning, professor keiko-san, supervirors, funya-san, sayaka-san were my audiences. I would like to express my sincere thanks to my professors, supervisors, supporters and all SFC members/staffs. Without your support, nothing was possible. Bbut my time in Japan was really memorable, beautiful and invaluable.

Problem with my laptop in my vmware-week

2007-10-10T19:03:00.000+05:30

Full of entertainment as well as full of trouble for me around this week. Last Sunday, we four interns were in akihabara. The traffic is almost closed inside akihabara on sunday and people come across the road for fun. We saw several fun programs and models (ha ha ha) advertising live on the road about company’s products. I spent almost 35 thousands yen on that day in akihabara by which I bought watch, USB HDD and next Digital Camera. Though I already have camera, I purchased the 2^nd one as due to its cheapness.

On that night, I did some nuty things with my laptop. I inserted my new USB HDD, created the disk and also I deleted the old hidden disk which contained some boot information and backup of my laptop. Fortunately, I backed up my all contents to USB HDD before restarting my laptop. So no problem at all. When I restarted my note, ohhh..it could not load OS from the BIOS. Uffff…. “OS not found ..press any key to reboot”. It was around 12:30AM night. So disconnected from net..what could I do? I could not repair at all on that night. My XP CD was alo not with me..coz it had alerady been taken by sudarshan at tokyo. I called sudarshan soon and planned to go to his dormitory early morning. Badluck, sudarshan couldnot find that CD in his room..suspected to be left on college. After having lunch from sudarshan’s room, we went to his campus for CD. Thanks god, I got the CD and started upgrading my laptop. The CD upgraded my laptop successfully but couldnot write boot information again. So same problem repeated. Then I just format all and reinstalled the XP. After fresh installation, no drivers of audio, video, network…..ufff..i had to go to LAB to make my note up. So I directly came to LAB and installed all drivers. Then got back to leo-palace by catching last bus from KEIO. Still I didn’t had office installed in my note. On the next day, I got office 2007 backp copy from chaw’s note.

XP installation process in my note in tokyo college

Installation Progress snapshots

Since two weeks before I have been working with VMware server installation and configuration. I had to prepare presentatin of my Vmware but all VMs from my note gone due to reformat. Extra burden……I just reinstalled everything and started analyzing my VMs again ha ha.

This week is my vmware week. i installed three FreeBSD in three VMs and tested with different network connection. VMware is really interesting. It’s a real OS emulation. Everything can be done with VM like what we can do with real machine. VMware DISK image creating (VMDK file), changing configuration on .VMX file and testing etc…

Yesterday I faced one trouble with test in my VMs. Then command “vmware-cmd” has several functionalites. We can control almost everythings from command line using vmware-cmd command like registering/unregistering VMs, starting/stopping/suspending/resetting VMs, changing the network configuratin and other configuratin parameters by setconfig command options etc..

I tried to change the network topology and make two routers conned to same network. When I ran the command:

#Vmware-cmd c:\virtual machines\BSD3\FreeBSD.vmx setconfig Ethernet1.vnet VMnet3

Setconfig (Ethernet1.vnet VMnet3)=1

It seems that it changed the network to VMnet3

#Vmware-cmd c:\virtual machines\BSD3\FreeBSD.vmx getconfig Ethernet1.vnet

Ethernet1.vnet = Vmnet3

But can’t ping to another PC, that means though the network changed, but didn’t show the effect of change. I roamed 3 /4 hrs on this problem. The solution is simple…I have to disconnect and reconnect the ethernet device to see an effect.

Nagatsuta cooking & Kamakura Tour

2007-10-06T18:35:00.001+05:30

This week, I entertained more. Cause last Sunday, I went to nagatsuta, sudarshan’s apartment where we traveled whole day around big supermarket. These days I become the nice cook ha ha. I cooked even in sudarshan’s room.

sudarshan just helped me in cooking ha ha

Today’s tour to Kamakura is another interesting part for me. We, four interns of SFC planned already to go to kamakura, the city equipped with lots of temples and historical places. We all are from different countries. Ni (Thailand), Chaw (Mynmar), Arif (Indonesia) and Dawadi (Nepal) ha ha ha..we enjoyed travelling around the kamakura city and beach. We visited big statue of BUDDHA. I knew, Nepal is the birth place of lord Buddha but Buddha is famous in japan. There were numerous people going towards Buddha and eager to take photos. I also took some snapshots of Buddha. It seems that kamakura city is like bhaktapur city of Nepal. This city has several temples.

Modern City of Japan: Odaiba

2007-09-22T19:37:00.000+05:30

Yesterday, I discussed with my friend sudarshan about our plan for tour to somewhere else around tokyo. So i invited him to my room yerterday evening. This morning we planned to move to Odaiba city. While I was in nepal, I heard that, there is a big city in Japan which is built just after dumping the garbase on the sea. Now I knew that the city established over the dumping site is Odaiba. Its another city of out of imagination for me. The city infrastructures, management and from every aspects, odaiba is nice city what I found. I am just a guest of japan for three months but sudarshan, who came one year before to tokyo institute of technology for masters study in electrical and electronic enginnering, is like habitant of japan. Fisrt sudarshan brought me to his university at o-okayama and we spent our whole day on odaiba city. I didn’t feel any tiredness walking around the city though we walked whole day around.

Last Sunday’s Trip: Enoshima Island

2007-09-11T19:40:00.001+05:30

Actually it was arif’s plan as to go to Enoshima island. Thanks my friend arif for your effort to identify such a nice island and beach close to our resident. Its just 10mins train travel from shonandai to enoshima beach and island. Wauuu..really small and pretty island I ever seen. This is my first experience walking around the island. The island is natural and piece having temples of budda’s and beautiful sceneries around the beach. We reached at the peak of island and captured several photos of beach and other peculiar food items specially sea foods. We spent our whole day walking around the island

Flash Back: SIGCOMM-2007 & ocean13 Movie in TOHO Cinemas KYOTO-JAPAN

2007-09-01T08:50:00.001+05:30

Yes, I returned back to my palace at ObaSobako Mae after one week conference (SIGCOMM-2007 data communication festival) from Kyoto. The one week stay at prince hotel and conference on ICC was really memorable as well as beneficial for me. I got a chance to talk with all presenters on this conference. I found that almost presenters were from MIT, California, Stanford, Cornel University, catholic university Canada, IIT Kanpur etc etc. The 2nd, 3rd and 4th day presentations were held inside big conference hall. 1st & 5th day presentations were held on F hall.
I am very much thankful to Keiko-san for such a nice opportunity to appear on this world’s top conference related to computer network. During this 5 days conference I met 3 Microsoft Researchers, FreeBSD Developer, CISCO managers and professors form different universities. By the way I became lucky that I got mail-id from almost all presenters. This is my big achievement and experience about to participate in such a conference and acquiring latest information about network/routing from IETF members, Microsoft researchers and professors. What I found that it is really incomparable about the learning technique of Nepal with other countries. Nepalese only learn theory but the most important thing is implementation. How OS can be developed, How routing software can be developed and what are the bugs on OSs and Routing, IPv6 networking and operation etc etc.. these are the major points what I learned in root level from this conference.

Thanks to Conference live broadcasting team (yoko-san, keiko-san, yukie-san, abazh-san, yoo-san, arif-san, dawadi-san, qoo-san…sorry I forgot other names) who worked full day to broadcast and upload videos online. All videos and pdfs of the presentations are available on http://www.soi.wide.ad.jp/project/sigcomm2007/. Anybody can see this videos online by installing VLC on their machine.
Thanks to SIGCOMM vice chairman for providing us two SIGCOMM T-Shirts and Books.

Ohh.. I forgot to write about ocean13 movie in TOHO cinemas hall Kyoto. Keiko-san provided us (me and arif) 4 tickets. Actually we can see any film on any hall of Kyoto city from these tickets. But when we got that tickets, we afraid about how to reach to hall. We hadn’t had sufficient knowledge about Kyoto city and traveling on train also. Anyway after getting nice instruction from keiko-san, we reached to TOHO Cinemas hall located near NIJO station. That hall had 7 screens. Different movies were running on 7 screens. Finally we conformed to see OCEAN13 on screen 5. The hall was quite small and nice furnished with fully equipped dolby digital sound system. Ha ha ha how peaceful during watching movie inside the hall. Nobody sounds except movie characters. I remembered, I had watched one hindi movie in jaynepal hall last time in Nepal (5 mnths ago sorry I forgot the name of that movie). When HERO came on the screen then people excited with big clapping. Ha ha ha..that is the difference.

Trip to KYOTO-CITY by SHINKANSEN and SIGCOMM-2007 Data Festival in ICC Hall Kyoto

2007-08-28T04:31:00.001+05:30

After around two weeks, I am coming back to my blog. Actually I was busy for presentation and practical analysis of OSPF routing in IPV6. fortunately after having presentation on Thursday, I heard that keiko-san was going to bring us to Kyoto city for SIGCOMM-2007 conference. SIGCOMM is the big conference in the world related to data communication and computer networks. It’s a great opportunity for a person who get a chance to present their paper in SIGCOMM.
Finally our trip was set. We had to come to Kyoto by SHINKANSEN, the world’s highest speed bullet train. Actually it was my great opportunity having trip with shinkansen as well as participation on SIGCOMM conference.
We two (Arif and me) had to come to Kyoto by bullet train. We were somehow afraid about whether we loss inside the transit, what could we do?? By the way, its was so easy to reach to the Kyoto city. Bullet train (NOZOMI-SHINKANSEN)!!! 300Km/hr, Wowww I cant imagine how Japanese build such a system/technology. Any way, our trip by bullet train was really memorable. Here is some snap what captured by my camera.

The hotel room was already reserved by funya-san for us. Grand-Prince Hotel, located just in front of the International Conference Hall is one of the highest standard hotels in Kyoto. I became little surprised by seeing the hotel room furnishing and its electronic toilet ha ha..any way we can live on this hotel for 5 days. Can you imagine the price of double bed room per day on this hotel?? Its 20000 yen/24hrs just for living, no any more dinner/breakfast. Lets see the picture of electronic toilet and other snapshots inside the hotel room. Sorry I cant explain the function of this machine, must be kept secret… ha ha ha

Lets come to the conference part. Conference started from 27th august. I am assigned to collect copyright agreement, control the UDL network to SFC and make summary report of the each presenter. I hadn’t had previous knowledge about how to make summary report of the presentation. Another thing, the papers presenting are sometime difficult to understand and also I have to catch up the speaker’s pace. Behind this, I am getting entertainment having inside the big conference hall and getting photos of this conference hall. I completed my 1st days responsibilities successfully. Thanks much keiko-san for providing such opportunity and I also got a T-shirt of SIGCOMM ha ha..

I never forget that day when we were in Akihabara.

2007-08-05T16:38:00.000+05:30

Yesterday, first holiday of the week in Japan so called Saturday. Abazh-san, Dedy-san, Arif-san and me reached YOKOHAMA terminal first around 1 PM. We were just directed to the famous electronic city of Tokyo Japan called Akihabara. Every body has plan as what to buy after reaching Akihabara. Actually we all are foreigner. Abazh, Arif and Dedy are from Indonesia and me from Nepal. Of course we all are not familiar with different places of Japan, even not familiar with Akihabara. We reached to the destination around 2 PM by passing several terminals in train. I would loss if I will be alone only inside the train terminal. How big are the terminals, faced in all fourth directions, can’t predict which direction to go? Dedy has a printed map of the city downloaded from Google.

Though we had map, its really difficult to identify the shops. Unfortunately every one had to purchase their items from different shop. Akihabara is a big city with huge buildings and show rooms of every electronic goods. We walked around the city more and more to find the places. It was a good chance to me to have site scene over there means I got advantage due to our unfamiliarity with that area.Ohhhh..i can’t imagine, what a big city with huge buildings and billions of items like laptop, Ipod, digital camera, PCs etc…after rounding about three hours we found out the camera shop what I had to purchase. I already set my mind to buy a camera with model no S6000FD of FujiFilm company. After having long queue finally I got succeed to buy my camera. It costs about Thirty-Seven thousands including a 1GB Memory chip.

My Camera

We walked around several shops of laptop. Dedy had to buy a laptop. He had model number with him but it was difficult to find out the shop having that model number. I became surprised by seeing store of laptops and cameras. It is billion in quantity.

No matter you can choose a laptop from billions of laptop. Then, don’t worry we can assign address to each items in Akihabara by IPv6 Addressing ha ha.

Abazh worried about his model number (Camera) about how to get that. It was already 7 PM during the search. Finally, Dedy and Abazh were not successful to purchase their items. What we concluded at last: input were lots of time, travel and money but output was only one camera ha ha.. how lucky I am. Fortunately that was the last piece on that shop which I got luckily.

We returned back Shonandai around 9:30 PM and took dinner together then directed to every body’s resident.

I assembled my camera on that night. It’s a so nice camera for me. I liked it. Though I am not the perfect camera man, when I hold my camera then I look like a professional camera man ha ha ha. Lets see some snapshots of my room captured by my camera:

Fedora Server and FreeBSD Router Installation and Configuration for IPv6 Operation Completed

2007-08-04T04:37:00.000+05:30

Abazh-San, thanks much for being my supervisor and assigning for FreeBSD Router and SOI Server installation to test for IPv6 only Operation.

Actually I installed FreeBSD and SOI server before two times while i was in TU. At that time i just followed the documents during installation. This is my third Installation but I have to do extra work than before i.e. migrate to IPv6 only operation. I need more extra study about IPv6 operations and address assignment. Probably I want to do my thesis over the implementation of Ipv6 and its operation in Nepal. Though I don’t have enough knowledge on Ipv6, I successfully completed installing Router and Server.

The basic packages necessary to operate with IPv6 in system are: NAT-PT enabled router, TOTD (Trick & Treat Daemon) which is a DNS proxy works only in ipv6 environment. Actually TOTD add an IPv6 prefix over IPv4 address. The IPv6 prefix is already fixed in /etc/totd.conf file. Other basic packages are routing packages (zebra, xorp). This is the workshop period in SFC-Japan. I and Arif are just supporting our supervisor on this workshop. This workshop is very helpful for me because I know how to convert IPv4 address to fake IPv6 address. Actually TOTD gives a fake IPv6 address of a client in the network. I also knew about how to handle Virtual Machine. This is an IPv6 environment, I am eating IPv6, but I want to eat more and more IPv6.

Let’s remember about yesterday’s surprise quiz:
Yesterday, Abazh-san unexpectedly took a surprise test to us. He gave us a set of questions to answer and we had to finish that in 30 minutes. There were 38 questions which covered all about our SOI network and system related. Out of 38 questions, I answered 30 questions properly. But after reviewing, I found that I did one silly mistake that was question about IPv4 Address Range. Especially the question focused about usable hosts range but I only cared about range of IP, so I chose range which has broadcast address also…..a silly mistake.

There was another set of questions which was a self assessment. I had to judge myself in network, system, unicast/musticast routing, Applications and UDL operations. Actually its difficult to judge by ownself. I found myself weak in Network/Routing and UDL Operation after my self test. So wake up baburd, study more on network and routing with IPv6…best of luck! Ha ha ha…

New Experience: Just knew after eating Japanese Items

2007-08-03T19:50:00.000+05:30

Today, i reached to Keio University on 9 Am. As before, we had to complete IPv6 Only Operation Workshop. Today, we had one operator from TU, Two from BUET, Bangladesh and Two from CHULA Thailand. Unfortunately CHULA guys were absent due to their own problem. Though we had 3 operators to be controlled, today’s workshop was out of expectation. Operators took more time on migrating servers in VM Ware Environment. So the workshop just finished on 7 PM. I am so tired now. Me with Mr. Arif left Keio around 7:45 and just dropped on a big supermarket but I don’t know the name of that supermarket yet. It’s a big supermarket I have never ever seen.
I tried to find out some items for dinner, specially curry items. I am not in mood to cook today due to tiredness. Suddenly I saw a surprised item. I couldn’t predict that whether it was fish or snake. It was an already fried item. I queried with Arif, but he also got confused, I just saw the price. Its written 398 yen on the rack but we couldn’t know what was written on its tag.

I decided to purchase that item. Actually it was long and look like snake. But surprised, when I reached into billing counter and processed to bye, by the way it was so expensive (1380 yen) but 30 % discounted. Then I got more suspected that it might be snake. We came to our palace, open up that item and analyzed, yes goooddddd it was fish, but I still don’t know which category of that fish. so delicious and with high diet. Though it is a small one I couldn’t eat all, so placed inside freeze for tomorrow.

Lets little talk about workshop with VM Ware Environment. On the workshop my job is just to handle RPT for power point synchronization during husni’s presentation and handle two operator’s activities during practical work. The fectoral machine is a thin one with 2GB RAM and latest specification. It has multiple interfaces, so on that machine we can run several VMs. One Fectoral machine is configured for 4 operators. Each operator can operate his RR, SOI Server and WinXP Client. So there are 12 VMs currently running on that machine. Its really interesting to monitor operator’s activity on VMs. We can watch every operator’s activity step by step on the VM Console. So it is easy to find out that which operator is doing well and which one is doing mistakes.

My first trip to abroad: challenges & opportunities:

2007-07-31T18:37:00.000+05:30

After 5 days of reaching to Japan I have now time to write my trip. My flight to Japan was July 24 1350 from Thai airways. I was so curious and thinking about how to reach to the destination. My parents were more worried about me and my trip because I was little weak at that time. This was my first trip to abroad so I got several confusion even on the Tribhuvan Airport but everything went smoothly. I was having little headache problem while on the plane. Thai airways international, but unfortunately I got a seat near cockpit. So couldn’t have site seen. Though the trip inside plane was so nice, I easily spent 5hrs in Thai transit because suvarnabhumi airport is so nice and well managed. I dropped at narita airport, Tokyo on 25th July 7:30Am. Everything is written in Japanese letter around. How reach is the Japanese language. Can’t understand the language at all. But I have the manual about to reach YCAT (Yokohama City Air terminal) by limousine bus. Thanks Ms. Soko Mikawa, for waiting me on YCAT. I am with Mr. Arif from Indonesia got into the soko’s car and directed to Keio University. I did several site seen from soko’car before reaching to university. I was so surprised by seeing the environment and technology of Japan. Everything through machine. Nobody walk around the road. Even no bike, cycle on the road. Only high speed car running around.
When I reached into the lab so called “Murai lab”, I am so surprised by seeing the lab that the lab is well furnished, every people (researchers) in the lab are so friendly and laborious. Actually the building is equipped with campus network, ai3 network and SOI network.

Abash-san is my supervisor. When I met him, I never expected that he is such a nice and friendly guy. I became so happy with him. He is so helpful. Recently abazh instructed us for coming IPV6 operation workshop. We have to help him on this workshop. I am little worried about it as that how can I help him on this one day workshop. Any way abazh, me and Mr. Arif spent 12 hours in lab on Sunday and Monday to make the workshop successful.

Finally today, July 31st, we successfully conducted the workshop. Operators from ITB and UNHAS successfully trained for IPV6 only operation. Tomorrow, we have five members to be trained for ipv6 operation. Monitoring operator’s activities from SFC is really exciting. Its really good opportunity for me having with such brilliant guys (Husni,abazh,Kotaro,Funya,haruhito…..) and I am really learning new things and hope this research time will be fruitful to me and will be my strong asset to upgreade our Tu network into IPv6 network.

Database security: protecting sensitive and critical information

2007-06-26T08:00:00.000+05:30

Bankers would be considered negligent if they locked a bank's outer doors and left the vault's doors open at night. Likewise, it doesn't make sense for an enterprise to lock down the network and leave databases vulnerable. Selectively protecting the most sensitive data that is at rest in databases from unauthorized access is critical, since that is where 90 percent of sensitive information resides. There is an important distinction between network security and data security. Database security does not supersede other security technologies, such as network-layer firewalls, network monitoring, SSL-secured communications, operating system and application hardening. But data protection needs to be in place as the core element of a complete enterprise security infrastructure. There is a growing awareness of encryption technologies to protect critical corporate data. Often companies do not realize the potential amount of risk associated with sensitive information within databases until they run an internal audit which details who has access to sensitive data. Imagine the financial damage to a company that could occur if an internal employee, such as a database administrator (DBA), who has complete access to database information, conducted a security breach regarding a secret formula, confidential business transactions, or personal customer identifiers and financial information. Also, the negative impact of media coverage about any security breaches can be severely damaging to a company's reputation, sales, customer confidence, and stock price.

Deploying cryptographically enforced access control to information in the database at the bank ensures that authorized senior-level bankers can obtain the data they need. However, the encryption keys and access are not available to DBAs or other employees in the IT department. The database security solution also protects information on back-up tapes that are stored off-site. The bank secures and stores in encrypted form root-level administrative passwords and passwords to other applications and systems (e.g. operating systems, email). When considering ways to protect sensitive database information, it's important to ensure that the privacy protection process does not prevent authorized persons from obtaining the right data at the appropriate times. It is important that your database security solution is application transparent. This means there is no need to make any changes to the underlying applications. The benefits for deploying application-transparent database security are faster implementation and low support costs. A key issue to consider when purchasing a database security solution is making sure you have a secure audit-trail for tracking and reporting activity around confidential data. Additional topics that must be addressed when selecting a database security technology are fast performance, the ability to work across applications, and how easy it is to implement. IT security experts often recommend selectively encrypting and securing sensitive database information at the data-item level to ensure excellent performance. You want to wrap each individual data item in a protective security, rather than simply building a firewall fence around the database. Once a firewall fence is penetrated, or if the security breach occurs from the inside, all of the data is immediately vulnerable. One of the best ways to develop an effective database security is recognizing that securing data is essential to a company's reputation, profitability and critical business objectives. For example, as personal information such as Social Security, credit card or bank account numbers exist in more databases; there are more opportunities for identity theft. Law enforcement experts now estimate that employees commit more than half of all identity theft cases with access to large financial databases. Banks, companies that take credit cards and credit-rating bureaus have to place greater emphasis on safeguarding and controlling access to proprietary database information. Audit committees have become stringent about protecting customer-related information and corporate sensitive data. Many companies are required to comply with data-privacy regulations, best practice requirements and industry guidelines regarding the usage and access to customer data.

The 2002 Computer Security Institute (CSI) Computer Crime and Security Survey revealed that over half of the databases have some kind of breach on a yearly basis and the average breach is close to $4 million in losses. This percentage is staggeringly high given that these are only the security problems that companies are reporting. Organizations don't want to advertise the fact that their internal people have access to customer data and can cover up their tracks, take that data, give it to anybody, and stay undetected and employed while a crime is committed.

There is much more illegal and unauthorized accesses to databases than corporations admit to their clients, stockholders and business partners, or report to law enforcement. According to Gartner, an estimated 70 percent of unauthorized access to information is committed by internal employees, as are more than 95 percent of intrusions that result in significant financial losses. The insiders who commit database intrusions often have network authorization, knowledge of database access codes and a precise idea of the valuable data they want to exploit. You can assign all sorts of rights, logins, roles and passwords to restrict queries and application usage. However, if someone can simply access the database files directly (either on the server or from backup media) they can see everything and anything. Most database applications, even the most sophisticated high-end ones, store information in 'clear text' that is completely unprotected and viewable. Business executives are collectively acknowledging that the security and confidentiality of information needs to be a lot deeper than protecting only the perimeter. Implementation time can be as fast as one to three days with negligible performance considerations. Security products are most effective when they segregate the responsibilities of access to sensitive information between the security officer and database administrators. Protecting confidential database information is not just an IT function - it is a business necessity that is critical to an organization's mission.

“School On the Internet (SOI)”, an online Internet Education Project in Asia
Introduction:

Online education is an education training delivered primarily via the Internet to students at remote locations, which encompasses any kind of learning that, can be done exclusively online. Sometimes this learning is through free, self-study websites. Often, though, students learn through virtual universities such as the WIDE University and others. Here, I am just going to focus about the school of internet project under WIDE University running since September 1997. WIDE university is an experimental University to research about the new form of higher education on the Internet infrastructure whose sole objective is to share lectures within Asian countries.

What is school of internet?

"School of Internet" is the studying environment to learn about the Internet on the Internet. It is difficult for just one educational organization to gather enough teachers that can teach about this whole new subject and also provide sufficient educational environment for people who want to learn about the Internet systematically. The establishment of "School of Internet" will be an important guideline to set up this new educational field by coordination of different universities of Asia. SOI ASIA Project utilizes satellite based Internet to provide Internet environments in a less expensive, easy to deploy, and more feasible way for the universities located in the regions where Internet environments are insufficiently developed; conducts research and development of the necessary technology for IT human resource development in Asia while using the environments; and proposes, through field experiments, a new educational methodology for universities in Japan as well as educational institutions abroad. As of April 2007, the SOI-ASIA project has 28 partner organizations in 12 Asian countries including Nepal.

Basic working principle of the project:

The Central control system of this online class is located in Shonan Fujisawa Campus, Keio University Japan. 28 universities of aisa are interconnected through satellite network and all member universities have client server control room and SOI lab to conduct virtual class using two way video conferencing. Professors from different universities from the world and experts from different companies (like Intel corporation, etc..) are requested to provide class about new technologies. Almost classes are conducted from SFC Japan but it can also be conducted from other universities also. The basic functions of SOI are:
Entrance registration

Course registration and authorization

Lecture archive and distribution

Q&A and students communication

Submitting reports

Tests and grading

Course survey

Class and conference from distance
( http://www.soi.wide.ad.jp/aboutsoi/aboutsoi_e.html for details)
Tribhuvan University is one of the partner organizations of this project. Center for Information Technology (CIT), Institute of Engineering (IOE) is handling this project as a member. CIT has SOI server control room and SOI lab to conduct virtual classes. Series of lectures (eg: Advanced Internet Technology, Object Oriented Software Development, Disaster Management, Bio-energy etc…) are being conducted. (Follow http://www.soi.wide.ad.jp/soi-asia/lecture.html to see all lectures conducted till now). Each site has more than two formal operators well trained by the project with responsibilities to handle SOI server and conduct classes. Operators announce class time and course title to students, lecturers and professors through notices. The presentation is being broadcasted live from the central (any one member university, mostly from SFC Japan) to all universities and at the end of the presentation; students can join to the question/answer section through audio and video conferencing. Students, teachers, professors from any universities, schools and campuses can join on this class.

Technical Part:

This project is supported by several ministries of Japanese government, and ran mainly by WIDE Project, AI3 (Asian Internet Interconnection Initiatives, http://www.ai3.net/ ) Project, Keio University and Asia-SEED Institute. The official lecture providing partners include Tokyo University of Fisheries and Marine Science, Agricultural Department of Tohoku University, Japan Advanced Institute of Science and Technology, Keio University and WIDE Project

In order to develop Internet infrastructure in low cost and short span in the partner sites, and develop distance education environment on the infrastructure, SOI Asia project designed
1) Lecturer site
2) Gateway site and
3) Student site
The lecturer site can be built anywhere as long as it has sufficient bandwidth to carry lecture video and audio in good quality to the gateway site.

The Gateway site is at Keio University, Shonan Fujisawa Campus so that it has 10Gbps connection to Japanese network backbone and also has AI3 project's C-band satellite antenna that can deliver Ethernet packets in 13Mbps.
Receive-only satellite antenna has been used at the student site using UDLR (UniDirectional Link Routing, RFC3077) technology. This technology enables the Ethernet packets to go through 13Mbps AI3 link and come back through existing Internet infrastructure such as telephone line or ISDN. This technology is realized by using special UDLR box and normal router based on FreeBSD. By using this environment, it is possible to deliver good quality video and audio to the student site, and get feedbacks from the student site through various applications based on their Internet infrastructure.
Mirror servers using Linux system are placed at the student site so that they can refer to their mirror servers when seeing the archived lectures, hence they don't have to connect to remote/overseas original server. Figure below shows the network configuration overview.

Application Configuration:
Three points in application design:
1) The stream can be multicast so that we can deliver lecture stream to multiple partners in Asia 2) The stream can be delivered to places without existing Internet infrastructure and
3) Interactive session based on student site's Internet connection is possible.

DVTS (Digital Video Transport System, RFC3189) or Polycom (video conferencing system) has been chosen for the connection between the lecturer site and the gateway site, and Windows Media Player or VIC (VIdeo Conference Tool) / RAT (Robust Audio Tool) for the connection between the gateway site and the student site. Various applications are being used such as VIC/RAT, Internet Relay Chat, Bulletin Board, MSN Messenger for the feedback from the student site to the lecturer site. The student site can decide which application they will use based on their Internet infrastructure.

Importance in developing countries
This is a call for a "Grand Challenge" project for achieving truly global connectivity. For over a decade, this project has hypothesized that the Internet could raise the quality of life in developing nations. Internet infrastructure is rapidly growing in Nepal. Growth in Information and Communication Technology would definitely improve the education quality. This is the age of globalization. So world’s education standards must globalize. Such projects have major contribution to globalize world’s education standards by conducting online live education which includes technologies of developed countries and share different countries education standards.
This is not to say the activity of the past decade has been a waste. The project has demonstrated the value of the Internet and raised awareness. The United Nations and the administrations of nearly all nations have acknowledged the potential of the Internet. The way has been paved, and it is time to act on what we have learned.

SOFTFLOWD, a flow- based Network Traffic Analyzer

Softflowd semi-statefully tracks traffic flows. Upon expiry of a flow, its statistics are accumulated and reports them to a designated collector host using the standard NetFlow protocol. Currently the statistics collected are summaries only: min/max/avg/total bytes, packets on a aggregate or per-protocol basis.

Softflowd can export using NetFlow version 1, 5 or 9 datagrams and it is fully IPv6 capable: it can track and report on IPv6 traffic and flow export datagrams can be sent to an IPv6 host. Any standard NetFlow collector should be able to process the reports from softflowd.

As softflowd watches traffic promiscuously, it is likely to place additional load on hosts or gateways on which it is installed. However, this implementation has been designed to minimise this load as much as possible. Alternately, softflowd can read pcap save files recorded from tcpdump and friends.

Unless reading from a traffic dump, softflowd run as a daemon. A "remote control" program (softflowctl) is included which allows runtime control and extraction of statistics from a daemonised softflowd.

Softflowd is developed on Linux and OpenBSD. It requires libpcap and its associated headers to build, these are available from tcpdump.org, or from your operating system vendor. As of version 0.9, there is some support for Solaris but this is still experimental.

My Horoscope of this week!!!

i born in feb. 16. according to english date, i must be categorized in aquarius (jan 20 - feb 18). lets see what my this week's horroscope told:

"They mostly are technical wizards with unusual ideas and rule computers, airplanes and astrology. They have strong convictions and seek truth above all things. Aquarians are practical and idealistic people with philosophical and spiritual bent of mind. They often take to rudeness, resentment and the silence that may burst out suddenly in extreme temper"

Then todays forcast:
After a long period of helping the people you love, it is perfectly okay to want to put yourself first today! There's no need to feel guilty. Instead, plan out your day with your happiness as your only goal. Choose a nice variety of your favorite things, and toss in a little splurge here or there just for good measure. You've proved yourself to be a good friend and a good partner. Now it's time to give some of that goodness to yourself!

ha ha ha ... actually i don't believe in horoscope but sometime its interesting and matched with real life activities.

My Added Concept of WIKI!!

definitely we heard the words wikipedia,wikimapia,nupedia etc etc..but what actually wiki is?? lets define what it is (taken from wikipedia site itself)

What is Wikipedia?

Wikipedia is an online free-content encyclopedia that anyone can edit. Wikipedia co-founder Jimmy Wales has described Wikipedia as "an effort to create and distribute a multilingual free encyclopedia of the highest quality to every single person on the planet in their own language." Wikipedia exists to bring knowledge to everyone who seeks it.

Who owns Wikipedia?

Wikipedia is managed by a nonprofit parent organization, The Wikimedia Foundation, which also manages the operation of Wikipedia's sister projects, including Wiktionary (a wiki dictionary), Wikibooks (textbooks), and others, and owns all of their domain names. Previously, the site was hosted on the servers of Bomis, Inc., a company mostly owned by Jimmy Wales. With the announcement of the Wikimedia Foundation on June 20, 2003, the ownership of all domain names was transferred to the Foundation. The site is run by the community of Wikipedians guided by the principles articulated by Jimmy Wales, including, for example, an adherence to a neutral point of view. The articles hosted on this site are released by their authors under the GNU Free Documentation License (or a free license), so the articles are free content and may be reproduced freely under the same license. See Wikipedia:Copyrights and Wikipedia:Readers' FAQ for information on how you can use Wikipedia content.

Who is responsible for the articles on Wikipedia?

You are! Actually, you can even edit this very FAQ, so long as the edits are helpful. This is a collaborative effort. Thousands of people have contributed information to different parts of this project, and anyone can do so, including you. All you need is to know how to edit a page, and have some encyclopedic knowledge you want to share. The encyclopedia provides users with a certain amount of freedom.

You can learn who is responsible for the most recent versions of any given page by clicking on the "Page history" link. Nevertheless, if you spot an error in the latest revision of an article, you are highly encouraged to be bold and correct it. This practice is one of the basic review mechanisms that maintains the reliability of the encyclopedia. As a result, Wikipedia has become one of the most extensive information libraries available on the Internet. If you are uncertain or find the wording confusing, quote the material on the associated talk page and leave a question for the next person. This helps eliminate errors, inaccuracies, or misleading wording more quickly and is highly appreciated by the community.

what is wikimapia?

WikiMapia is an online map and satellite imaging resource that combines Google Maps with a wiki system, allowing users to add information (in the form of a note) to any location on Earth.

Created by Alexandre Koriakine and Evgeniy Saveliev, the project was launched on May 24, 2006 and is aiming towards "describing the whole planet Earth". WikiMapia is unrelated to Wikipedia and the Wikimedia Foundation, but the website states that it was "inspired by Wikipedia."

WikiMapia allows contributors to add a "Hotspot" to any map by marking out a rectangle (with the maximum length of any one side being 20 kilometers) which is wiki-linked to a note providing information about the locality. The note may be in any of 60 languages currently supported, and may be modified by any contributor, as in a wiki. The link is activated by clicking within the rectangular "Hotspot".

Growth

By August 16, 2006, one million localities had been identified. . The counter passed two million on November 22, 2006 and 3 million on March 8, 2007. A project has begun to translate the user interface of WikiMapia into 64 languages other than the current English interface.

Especially in some areas of the world with out-of-date or very expensive mapping, such as India, growth has been phenomenally rapid. However, this rapid growth has brought problems of its own with urban areas being covered with thousands of overlapping rectangles marking the position of private residences, but with no facility available in the WikiMapia interface to display places of public interest (as opposed to those of very restricted interest such as private houses, flats and apartments).

In the initial implementation, WikiMapia had no registered users and no administrative hierarchy. All users edited anonymously and there was no mechanism for monitoring or disciplining problematic users.

A user registration system started to be introduced on 8 October 2006. Users who have been registered for three days or more are granted some administrative powers, including the power to move, resize, delete, or protect objects. "Points" are granted to active users for adding, reviewing, and correcting places; as points accumulate, a user is allegedly granted additional powers. Active users of Wikipedia, and users in contact with Wikimapia before October 5, 2006, are exempt from the three-day waiting period.

Another feature of WikiMapia (that has now been scrapped), was the sight "car" which zooms in and out over smaller and larger areas. It was used for exploring both maps and satellite photographs. There are now small `cross hairs' like a telescopic rifle sight at the centre of the page instead.

On 23 March 2007 the ability to outline an irregular polygon in green (in addition to the original rectangle of variable size) was introduced in Wikimapia.

now, i hope everybody must know about wiki. so here i want to add another wiki that is related to academician (trainer,lecturer,professor).

i am studying masters in information and communication engineering. i am also a lecturer upto BE label. lets think, when a lecturer in blackboard teaching you about computer network...

how OSI model works? how TCP/IP slidding window protocal works? how packets are transformed from source to destination? etc etc...

your teacher just write notes in blackboard and explain it but practically he doesn't know how it works??

similarly, in telecom network, how voice data transfer, call established, call accepted/rejected etc etc..

lecturer of data structure & algorithm can teach about how link list works? how to find shortest path using dijkstra's algorithm? etc etc..

lecturer of semiconductor devices can teach how JFET/MOSFET works etc etc...

in this way only giving theoritical knowledge about practical subject is not practical. so almost engineers of nepal are useless.

do you know how can a CD be read/written?? you can answer. but can't explain practically and practical explanation is also not possible.

so here i add a concept of "wikisimulia". i.e. www.wikisimulia.org same like wikipedia and wikimapia. wikisimulia can explain/answer practically all about the above questions. what i hope is, a teacher in a class with laptop and having wireless internet facilities and while teaching if he need to teach practically, he can go to www.wikisimulia.org and can show the demo of current lecture to his students on the spot.

so wikisimulia is an encyclopedia of any type of simulation of any subject where any public(expert, programmer) add his simulation to this page and any public can access and see the practical implementation through simulation.

so lets design and standardise the concept. simple concept is just develop simulation using java applet and upload to this site. this is my idea but there are several other techniques.

do you guys anybody have idea/concept about it??
any way thank you for reading this article. and the site www.wikisimulia.org is an imagination and hope will be developed in future...

[there is also a site which gives theoritical concept with picture (http://www.howstuffworks.com/)]

A Scenario, Marriage with Nepalese tradition(13 May 2007).

Yesterday, i just attended one marriage ceremony of my relatives(MaMa ko chhori). i saw the environment, realized the environment and activities of marriage. actually my father giving me pressure these days for marriage to me but i just denied and not talking with him also about mariage.

so adult people from village, old and experienced mind, traditional habit, full of cultural and social activities. i saw some marriage processes where i found how marriage would be done in nepalese tradition. its just a typical nepali tradition. actually my habit is just opposite from some nepali tradition. i don't know this is due to my proudness or i become advanced or i am out of track or cultural & technological gap with them. i want to save the nepali cluture but want to improve so as to bridge with the new world.

my father little angried with me that i denied his request. i just reached near a gang of my parents label where is te gang of peeople over 60 years old and all having educational status below Intermediate and from village. what they talking....."we have to save the culture and society..we have to continue this marriage style until we live..no matter our new generation will follow the culture or not after our death but it must be until we alive. Almost people who live in cities and educated are having bad cultural habit and they just follow the international style..its not good etc etc...." i just realized and analyzed. i am also in new generation and lit. bit educated. so i felt that they are talking indirectly to me. i knew, we have to save the culture and nepalese tradition but what i want is we have to refine the culture with time for the development process otherwise nepal will remain on this stage(stone age) for the next 1000 years where as other countries......still people remained on this stage and they dont want to improve themselves then how the country and people of this country will develop yar..though for living every creature, culture and society is the most important part. we can't live without our culture and society. our main moto is to improve the culture and social activities and develop the country. but what can i do???????

conclusion is: "try to refine the cultural, social & make technological gap short between old generation and new generation."

recently i returned back to my office for meeting. after that meeting, i came to hostel and took some photos of myself and friends in hostel. the following are the some snapshots...

Japanese Prof. Dr. M. Kubo & IOE prof. Dr. S.R. Joshi's Suggestions,

its time about 4:35 PM wednesday, 11th april 2007 at staff conference room of IOE computer department where we always take masters class. unexpectedly my prof. Dr. Joshi came up with japanese prof. Dr. Kubo. unfortunately i am little late in the class though profs. didnt start class yet. Dr. Kubo did Ph. D. from Sofia University japan and he established "Kubo Institute of Science & Technology" as far as i know from him. He did his Ph.D. in physics though he is interested in IT and computer science.

we students were late on this class. so our prof. Joshi so angried with us. i think its obvious. we have to respect our proffessors as he teach us for us and brought profesors from several countries to make a visit to us. i have never seen such more professors in IOE who is doing for Institute, students and country except Dr. Joshi. i am really glad. lets summarize what these two professors suggested us:

summary words: TIME,Philosophy,Laborious,Domain Knowledge,Morality,Entertainment,do 4 Country.

Dr. Kubo wrote that TIME=>CHANCE. he is about 65 yrs old though he is so energetic in knowledge sharing. Definitely we have to know the TIME. we have to play with TIME so we can grab the oppertunities. we have several oppertunities on our hand. both professors suggested that every body must be responsible in his DUTY. though except duty, of course he has time for family and entertainment that is also the most necessary part. he said "never sell your morality, its the most important, expand knowledge in everyfield as possible as you can, do entertainment at the time of entertainment, so its not bad having girl friend ha ha ha ...he laughed." i am so impressed by such a friendly professor that every body must be like that. some time he angried with us saying that "you late commer, i hate late commer, be in time, time is the important".

if IOE has several such professors, what will be the status of IOE?? its only imagination till now.

Last Monday, Prof. Joshi came up with Prof. Kubo in CIT, IOE. as i knew that Prof. Kubo want to promote IT industry in Nepal. it was a good oppertunity for me to show the IT infrastructure of IOE but unfortunately Internet link from NTC was down on that day having Optical Link problem from NTC. Dr. Kubo just tried to show about his profile and IT infrastructure of his institute. Sorry!!! Prof. Kubo as net was down on that day. any way i saw your profile on the next day from http://www.kuboinst.com. so impressing.

any way, its a nice interaction having such professors with us in the class.

How does a laser speed gun work to measure a car's speed?

Laser (or lidar, for light detection and ranging) speed guns use a more direct method that relies on the reflection time of light rather than doppler shift. You have probably experienced the reflection time of sound waves in the form of an echo. For example, if you shout down a well or across a canyon, the sound takes a noticeable amount of time to reach the bottom of the well and travel back to your ear. Sound travels at something like 1,000 feet (300 meters) per second, so a deep well or a wide canyon creates a very apparent round-trip time for the sound.

A laser speed gun measures the round-trip time for light to reach a car and reflect back. Light from a laser speed gun moves a lot faster than sound -- about 984,000,000 feet per second (300,000,000 meters), or roughly 1 foot (30 cm) per nanosecond. A laser speed gun shoots a very short burst of infrared laser light and then waits for it to reflect off the vehicle. The gun counts the number of nanoseconds it takes for the round trip, and by dividing by 2 it can calculate the distance to the car. If the gun takes 1,000 samples per second, it can compare the change in distance between samples and calculate the speed of the car. By taking several hundred samples over the course of a third of a second or so, the accuracy can be very high.

The advantage of a laser speed gun (for the police anyway) is that the size of the "cone" of light that the gun emits is very small, even at a range like 1,000 feet (300 meters). The cone at this distance might be 3 feet (1 meter) in diameter. This allows the gun to target a specific vehicle. A laser speed gun is also very accurate. The disadvantage is that the officer has to aim a laser speed gun -- normal police radar with a broad radar beam can detect doppler shift without aiming.

"professor's questions during my project presentation"

sorry i am late to post this importance topic, its due to my busy...actually on 16th january 2007, our department(DOECE, IOE) set that day for our masters project presentation. externals of the presentation are:Prof. Dr. Sashidhar Ram JoshiMr. Jeeban Kumar Pant &Mr. Daya Sagar Baral
my project was entitled "NTLM HTTP Mechanism for Proxy Authentication & HTTP Log Mining". this project has two parts. fist part is related with Authenticating internet users thru proxy with NTLMSSP authentication technique and second part is analyzing the web server's log file and generate web report.
though i am not perfect in UNIX, i have little known so i tried to build project in linux. after the presentation completed i got the following question to me:

what is the interrupt no. of SAMBA server?
ur project is real time based impleting in CIT, what is the performance of the server i.e. do u know latency? u already studied in OS but forgot...
tell me the performance measurement algoithm? do u know any algorithms? like round robin algorithm and etc etc....? (Disk-arm scheduling algorithms i thought)
have u heard any unix based machine? (i answerd: i installed mac 0.9.1 to Apple computer, but that was not the answer re answer was: spark machine ma solaris os re)

5. what is that logMiner_0.1.tar.gz? (i answered: that is package of c source code what i developed for log file analysis)

questions from baral sir

why u use samba server? SAMBA is just a netwrok environment ko server hoina ra?
can't you make unix machine as domain controller? why u used winnt domain users?

Questions from JKP sir

JKP sir focused on report and he commented about my report writing style (really appreciable, its a nice suggestion)

now i want to be clear that, actually i can't answer Q N. 1. i partially answered Q 2, 3 & 4 because i hadn't expected such questions.i found Baral Sir Questions as nice questions. and thank you JKP sir for the nice suggestions.

now i request to my all friends who knows UNIX that what is the answer of question No 1. I felt shy that i cant answer though i am system engineer of CIT, IOE Pulchowk. i will be really greateful if some give answer of that first question.

Thak you.

My New Experience....Nagarkot Night Camp,

Last friday, my m. sc. class mates planned to go nagarkot night camp as a party for being Telecom Engineers by 4 class mates(prakshet,dinesh,nabaraj & sujan). as the plann was designed before our final masters exam.
as per our plan, we left kathmandu from IOE at 5 PM. we were 13 friends among 16. other friends were absent, but i didn't know why they absent. we were drived to nagarkot thru 7 bikes. i was behind prem's bike upto bhaktapur salaghari and switched to meen's bike. it was almost night around 7 Pm we reached to the destination hotel.
actually i didn't know what is camp firing. on that day i am entertaining with camp firing. its nothing just seat around the fire, keep warm and drinks. bashanta, the event manager of that program managed all the drinks. he managed sprite for me, thanks. Around 8 PM friends started uploading whisky, bear, wine etc...what can i do? some friends forced me to drink hard but i never. i completely rejected then my senior friend told me that "babu sir, have u ever drink wine which specially for ladies, we have wine today." then i replied "ok sir but don't want to be lady". laughing.....all friends...he replied "don't think so..we are just entertaining.lets check how is ladies bear. we must take experience of everything." i excited then and ok requested to the event manager for half a glass of wine. then the manager replied me that..."u don't get full glass because we didn't have sufficient wine..laughing."
that was my 1st experience when i took wine. friends were fully entertained up to 2 PM. playing madal, guitar, and songs..antaksheri etc...
at 10 PM, i just want to sleep but friends didn't want me to sleep. any way i tried...i told that i want to go toilet. from this clue i went to sleep but prem was following me so he got back me to the spot again and starts dancing. any way friends were full. so grabing this oppertunity i went to sleep. at 12 PM, manager came and waked me up for dinner. we took dinner and then went to bed.
some friends still got entertaining by jokes (so danger jokes yar......i never heard before...real jokes of their life...ha ha ha ha). this was my time to be in nagarkot. i know i have to catch son rise early in the morning. manager waked up all friends at 5 AM and we went to the nagarkot tower around 6 AM. took several photoes on the tower....so nice son rise..amazing.. i will upload all photoes later in my blog.. we returned back from tower at 9 PM. i was behind prakash dai with meen's bike. unfortunately i the bike slipped on the road where mobil on the road was the main cause. we both failed on the road that i just jumped over and prakash dai got little wounded around heap. by the way i used my both pam first on the ground and god... i was not wounded at all. thats a bitter experience(bike accident). any way we reached to our hotel..took photoes at another beautiful spot and got back to kathmandu. i went to my home at banasthali and just slept whole day due to early night's hanged up.
so i felt so happy that we all succesfully returned back thru bike and got full entertainment...thanks to telecom engineers for giving us such a beautiful event in my life..

Mass Assessment Bunked in Communication Theory (3rd Dec. 2006, Sunday 8 PM)

today, i am feeling little unhappy because we(M.Sc. Students) rejected an assessment examination of communication theory, really a complicated subject in our masters course.
from the past history and present status of this subject we felt that we couldnot attempt the exam that means we could write nothing in the exam. so we all were ready to stop the exam and planned to request our teacher(Daya Sagar baral).
as per our plan, our discussion started with sir 30 mins before the exam. we requested to our sir that we were really sorry because we were still not fully confident on this subject so either convert this exam as assignment or lets shift the exam. unfortunately our respected sir denied to do anything and we had to appear the exam by force. every guys had set their mind not to appear the exam but planned to just get the question paper and left it blank.
when our sir supplied question papers toward us, my heart blinked a bit more.
ussssssssssssssss what a nice question. but my one friend told to left the exam and really he went out from the room.. continuously other guys left the room. and we finally rejected the exam though the question paper was so easy and could be easily solved. my mind became offset that we really sorry with our teacher. such a situation was never happened in my life and my studies. what our teacher felt?
so we are really sorry for that. it was our mistake that our thought is completely negative with this subject means its really a difficult subject. i think difficulty of subject matter depends on the teacher. we are very positive with our teacher and our teacher is really positive with us too though we were not able to appear this examination. sorry again for this.
any way the exam shifted to next sunday 24th mangshir 2063 which is just two days before our final masters examination of the same subject.

best of luck!! to all guys for the assessment and final exam of this subject(Communication Theory) and best of luck!! to me also.
next assessment of digital image procesing is comming soon. i think we have to study in time otherwise same events will repeat. so baburd, left writing to this blog. just stop and start preparing the assessment and final exam of ur masters course.

what do i felt today (Early Tuesday, 3:20AM) ?

wauuuuu i woke up early in the morning. Its too cold, the environment in IOE, so i always wakeup after 7Am morning. but i don't know why i woke up early this morning.
ya i knew that my exam is coming soon. i have to study more because some subjects are too difficult for me. another thing what i felt today that almost time i am in IOE with Job & in Hostel. what my parents thought, every parents want their childs always with them. though my parents live in kathmandu i rarely meet them once in a 20 days.
so i feel today that "what is love". love is really a big thing, i know how much my parents love me but i always didn't feel that=> "बाबु आमाको मन छोरा छोरी माथि, छोरा छोरीको मन ढुङ्गामुडा माथी". but sometimes i confused with the word love & like. if someone else tell me that "i love u bro?" or "i like u bro?"... hummmmm what is the difference then..so i must have to take care of my parents & my family that is waht i realized today & "TRUST" the word is important in life.
but i don't know how i woke up early...ohhhhh yaa i think my parents are far from me now, they went my old village. still i don't know when they come back. any way my parents! i am waiting you in kathmandu. best of luck your trip to village.
final exam ko pani little little tension badirachha...

Today 17 Nov. 2006 Friday,

i am writing this blog after a long break. actually i felt so unhappy today that DNF (Dalit NGO Federation) account head indirectly deny me to provide experience letter of my work. i had developed a project i.e. "Electronic database of Dalit NGOs of Nepal" which was web based project used ASP Script with MS-SQL Server & Nepali Unicode.

i trusted DNF and project supervisor on this project and completed in time before of my payment. still DNF has to pay me Rs 5000. but they are just lingering to pay and i went Three times for this payment and experience letter. i have a contract paper signed between me and DNF. as per my contract i completed my job and requested for payment as well as experience letter but the guys why they behave like "come tomorrow, come tomorrow ......". just print the letter and get signature from director, it takes about maximum 3 minutes but the related person is always busy except that he has sufficient time joking with other staffs and sufficient time for lunch. why such Nepalese guys (specially NGOs & INGOs) are not trusty and helpfull? i don't know what they want from me. i think i must get what i did. i didn't ask for the illegal work..............any way lets see, i will try more & more then once i will be successfull. when i success then i will write another blog

Today 9th Nov. 2006, Thursday

i just wakeup today and socked that i did nothing for the Masters project. i need GCC Compiler for C programming in Linux so as to analyze the log file of web server. though several friends suggest me to develop the project in Pearl-CGI but i not confident with Pearl. so i choose programming in GCC. not only this i need to analyze the performance of diferent proxy authentication techniques for WinNT domain users. ohhhh, i need heavy study for SAMBA, WINBIND/LDAP,NSS,NMB and NTLM. But unfortunately i still starts nothing.

Wakeup baburd!! there is no time for you, because your final exam is comming soon in one month, so finish the project before exam. my today's time is consumed by Prof. Timila Yami Thapa cause i have to help her for a presentation about policy to develop ICT for Nepal. She is recently going to present as representative of IOE on the intellectual forum. so i downloaded almost all the ICT Acts, telecom policies/Act etc.. for the help to mam.

Today 3rd Nov. 2006, Friday,

my daily works completed normally. but i made a mistake because i have to go NITC to discuss about mail server setting. NITC, Nepal's main IT governence body still don't have web based mail. so Dr. Subarna, Executive Director of NITC requested me to configure mail server. for this, yesterday i gave a word to DB Rawat to go NITC together to discuss about this issue.but i just remembered that today is the time to hire Network Engineer in CIT through Interview.By the way there were only three candidates appeared in the interview, one comedy is that 2 among three are my class mates so i was in trouble that i can't support any one coz both are my mates. any way all candidates appeared in the interview. lets check who will be the successful candidate for Network Engineer in CIT.Due to this chakker of interview i forgot to call DB and to go to NITC. no matter let we go another day, don't angry DB dai with me hai.
so today is normal for me but little interesting also, i called my special friend and started talking. the talking was so lengthy that i just remembered after i checked my watch. it was one and half hour contersation, so amazing. what was the topic to remain in phone all over this time? ok keep secret.at the evening, i appeared in the masters class of Communication theory, when baral sir talk about assignment, hasssssssss i completely forgot to complete the assignment. then i committed to submit the assignment on coming sunday. ha ha ha almost students try to ignore assignment what i show today. i felt this becasue i am also a Teacher of BE students.

31st Oct. 2006,
My Friend Prakshet of NCIT remembered me yesterday and requested me as External Judge for BCA Final year Project. so i appeared on NCIT around 12:45 PM today and the project presentation starts.
Almost all the projects are developed in VB/MS Access, VB/MYSQL, PHP/MYSQL. The Project Titles are like Hotel MIS, College MIS, Online Shpping etc...i.e. of same pattern. Any way students worked hard for their project but i think Final year project is not so easy. It must be hardly/Laborously developed. These days, there is tough competition in market for job to BCA Students even its tough to BE students...JAMANA COMPETITION KA HEYEEE. so every product must be competitive and must do struggle even in Nepal.
The presentation completed at 5PM. I got Rs 2500 as remuneration from NCIT. Actually i was bankrupt today. so thanks to NCIT & Prakshet ;) .
I felt nice experience as an external examiner in another college like NCIT. Sometimes it will be usefull for us because we old engineers may not know about new technologies, new software packages in market and new programming style. Experience is the most in life what i feel.

today 30th october 2006,

first of all i joined to SOI Operator's Meeting thru mIRC, VIC/RAT from IOE,TU. Actually the job was so simple because all the steps of configuration was alreaded provided by kotaro & husni from SFC Japan. i did as per the document like MTU setting, UDbox site Ip address change and Udbox segment renumbering.
but kotaro didn't send me the steps for UDbox segment renumbering. from mail he recently mailed me the steps of UDbox configuration. By the way we are using Sony box in place of UDBox. but Kotaro just thought that we are using UDBox. so just misunderstanding. i am roamed with steps for Sony Box but Steps for Sony Box had already been completed by me which was then cleared by kotaro. then Network was up but no VIC/RAT working. The main problem was that sony box can't work with MTU 1500. so first step had been reverted. i made certain change in /etc/rc.conf and machine restarted but problem......:( . then i didn't query SFC teachers rather i tried to find the solution in net. i can't get solution in net. The main problem is that the kernel is displaying lots of message so that i couldnot edit /etc/rc.conf. it was about 1/2hr i tried to fixed but still not found the solution. at last i remember the command ifconfig fxp0 down and ifconfig fxp1 down. thats all , after that no any kernel warning, i changed rc.conf file and again up the network. so simple.
actually i took almost 3hrs but the job was actually 5 mins. ha ha ha, how much effort!!!!
any way, i felt nice today. nice experience.
