Events and Trip from the beginning were Memorable

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.

मेरो नेपाली पत्र र बिधुत प्राधिकरण।

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

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

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

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

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

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."

Best Regards,
Jyoti Tandukar, Ph.D.

I will disclose what the Sauraha declaration was ,only after there is some movement on it. I am fully supportive on this activity against parties and government who are not responsible to this country.  we want to raise movement on "National Issues" not political and individual.

thank you,
Babu Ram Dawadi

Where is Nepalese IPv6 Task Force

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 (  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( 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 ( 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 ( with IPv4 and by 2011 there won’t be IPv4 address any more. ( ,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. (

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 (

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

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!!!
