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

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.

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

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

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.
