Next Generation IP, IPv6

I'm trying to put a little touch of tech here. not just crap words :p
considering there are not so many articles about it/them in Indonesia, or Indonesian itself. so I hope I can do a little contribute... enough for the crap. Let's get start...

IPv6

Bisa dibilang hampir semua komputer (bukan cuma komputer sih..) masih menggunakan alamat IP (Internet Protocol) yang masih konvensional hingga sekarang, yaitu IPv4. Jumlah alamat IPv4 emang banyak, karena terdiri dari 32 bit, ya total 2^32. jaman dulu waktu standar ini dibuat emang masih lebih dari cukup. tapi sekarang ketika seluruh dunia berlomba2 terhubung ke internet tentu aja pengalamatan ini udah gak relevan lagi. beberapa solusi sementara kayak NAT, seperti namanya, hanya solusi sementara karena pasti seluruh device bakal terus bertambah.

so, sekarang para pakar internet udah sejak lama menggagas IPng, yaitu Next Generation Internet Protocol, yang memungkinkan semua komputer/device di seluruh dunia terhubung secara langsung agar dapat berkomunikasi. Protokol Internet ini dinamakan IPv6, yang memiliki panjang 128 bit, sehingga terlalu panjang kalau diungkapkan dengan kata2 (ca elah... :p)...

contoh IPv4 : 172.168.2.232
contoh IPv6: 3ffe:0501:0008:0000:0260:97ff:fe40:efab
Keliatannya hebat banget, kan? tapi tentu aja bukan tanpa masalah. kenapa? yaitu kita tidak bisa langsung mengganti perangkat komputer/eletronik di seluruh dunia ini dengan perangkat yang support IPv6 langsung. bayangin aja, ada berapa komputer di seluruh dunia? dengan OS yang berbeda2 pula. maka diperlukan sustu mekanisme tertentu untuk menjembatani pindahnya pemakaian IPv4 ke IPv6. Cara ini disebut Mekanisme Transisi. standar terbarunya ada di RFC 2893, menunjukkan berbagai macam teknik yang bisa digunakan untuk transisi.

Secara umum mekanisme transisi dibagi dalam 3 kategori :

1. Dual-Stack

2. Tunnelling

3. Translasi

1. Metode Dual-Stack bisa terdiri dari Dual-Stack Host, atau DSTM (Dual Stack Transition Mechanism)
2. Tunneling (koneksi antara jaringan/host IPv6 melalui network IPv4) terdiri dari:
- 6over4
- 6to4
- Teredo
- Tunnel Broker
- Isatap
3. Translasi, metode ini dapat menghubungkan antara IPv6 dengan IPv4:
- NAT-PT
- SIIT

Implementation

I'm working on a little tunneling of my final task. pengen didokumentasiin dikit di sini. untuk OS yang gampang aja lah.. ;)

Pertama saya coba bikin prototipe jaringan kayak gini


sebagai catatan router menggunakan PC router.
Spek PC:
- R1 dan R2, OS GNU/Linux Fedora Core
- PC1 dan PC2, Microsoft Windows XP SP1

setup client (PC):
secara default IPv6 untuk windows belum diaktifkan, install aja dulu. bisa dari "Local area network" properties, klik install, pilih Protocol IPv6. atau supaya lebih enak lewat command prompt supaya ntar bisa sekalian konfig dan tes IPv6-nya. setup untuk PC1 dan PC2 dilakukan dengan cara yang sama. tinggal setting IP nya saja yang berbeda.


C:\>ipv6 install
C:\>ipconfig

Windows IP Configuration

sudah terlihat konfigurasi alamat IPv6 yang ada, yaitu alamat link-local. Dari interface yang terlihat di atas, terlihat beberapa interface tunneling untuk IPv6, yaitu Ethernet (LAN), Teredo, dan Isatap.

waw... lama juga ya bikin tulisan gini doank... ntar dilanjutin lagi deh... ;)

inlander.web.id

Finally, I got my own domain for my blog. the name as what I wanted before; inlander.web.id. a little confusing configuration was to set the free DNS to tell where is my real blog address is.

I tried to use freedns.afraid.org. a freedns hosting & forwarding for domains. I thought it wasn't working well when I didn't find my domain couldn't be accessed. I also tried to search any free DNS hosting. but none of them work as good as freedns.afraid.org. even when I followed the instructions from blogger itself. after a night working on them (I also searching for any domains can be named as iphone, oh God, I'm obsessed with this stuff... ;)), I got them both. they are my .id domain inlander.web.id and iphone on iphone.awardspace.us. I redirect them all to my blog on blogger. I think it ill a little longer for awardspace to reach my blog.

I'm trying to get another domain, ikhwan.web.id.. ;)
oh, no..... my final project.... :0

Have a nice going to a new life to Rasyid :)

We were attending Rasyid's (Cyb3rh3b) weeding in cilegon. what a tiring trip to go there. and what a prodigal car. It really wasting gas. the acceleration was so good for a van car, but it spend much money on gas. so we were really loss on it.

actually, the trip was not bad. we met some people that missed. our seniors, although there still some of them couldn't go too. that was my first trip to Banten after several years I haven't gone there. I think I went there when I was a kid.

we hardly could find the building that was being used for the wedding. we didn't have the address of the building. just Rasyid's house. so we went there, and ask people there where was the wedding was held. damned... the building was on the road we have passed before. so we turned back. and, the trip was full of miss directions. we went here and there and so long we could find the place we wanted to go. but finally we could reach them.. :P

but the fun was we went to Anyer beach after had some lunch at the wedding. the view at the beach so beautiful, even though it wasn't the most beautiful place there. I also haven't been gone to beach after years, cause I stay in Bandung. we had a little enjoyable moment there playing on the beach and the water of sea. (actually I wanted to bring some sand from there :)).

Well, the most suffering way was on the way to home. The gas was about to drain, also our money... :( so we tried to save the gas by switching the AC off. by the needle was pointing to the zero, Iqbal was so worried that the car was gonna stop helpless meanwhile we were on the highway to Bandung. but actually I believed that the gas was still enough to reach Buah Batu (even thought I still had a little worry :P) so finally we went out from Pasteur finding a gas station there, when we find it on the left side, we missed it, so we have to fall back a little.

That was it, a tiring trip to Banten, Cilegon, and Anyer. Alhamdulillah we reached Bandung in safe again. I hope we can have a trip and moment like that again in some other time... :)

DZ

I called DZ, I'v been missing her. I don't know, I think there's something when I had a feeling that I wanted to call her. My feeling was right, when we had a many chats and talks, we arrive at a talk about her birthday, you know... It's tomorrow, means 1st July. woww.. that's why I felt strange.

We talk much, about erk until eyeglasses. so many so I can't remember again. It was quite long, about almost 2 hours. well, that was really cheap using esia. I planned to buy some gift for her. just a little thing for friendship :) She'll gonna go to jkt tomorrow, having a job recruiting test there. I hope she will get any job she wants and suits her.

Well, I wanna say again: Happy Birthday to you again, DZ. Have nice day and good luck. Hope the best come to you... hope we 3 can gather again later, soon... ;)

Progress

A long time of idle and searching for task was boring. I don't know, I haven't done the typing. but fortunately I have got the way of the method that I use. the 6over4. thanx to Microsoft that have included the tunneling for ipv6 in Windows XP Pro SP 1. after a long time, I just knew recently. I thought I would use any opensource OS like GNU/Linux or FreeBSD.

Well, I think the time for playing is enough. It's show time. It's the time to act. become active, just don't listen at whoever say that it is musn't be done or can't be done. The most important thing is The Effort, and I believe I CAN DO IT!!!

Wish me LUCK, guys!!! ;)

Posting

As you see, I always tried to post in English, every post of my blog. It was one of the way for me to practice my English. but I found a little difficult to let my creativity out. A little hard to express myself. so I think I'll try to post
in Indonesian too.

Now, the connection speed of each VPN account of my campus has been decreased. I feel so bored with this. we can't feel anything with the speed. It is so slooowww...

These two weeks are the exam week, it feels solitude. the last lecture I had for exam on Monday wasn't the best thing I could do. but I did a quite effort to do it. I hope the result will satisfy me...

Well, now is the vacation time ;)

Feb 9-11 2007

It was my first trip to Palembang. Attending my cousin's marriage. Unfortunately we only had 2 nights time there. Well, may be if I just go by myself I would stay longer. I just have the chance to upload my pictures that we took there... Here they are:


On the plane... I hope we wouldn't fall down. There have been so many plane accidents recently..






The night beside the Musi river and the Ampera bridge.











The Ampera Bridge

...was about to home...

The Musi and The Ampera from the sky

I got it...

The rain comes everyday this week. every afternoon almost. Actually I've promised that we could go to Plaza Dago (PlaGo). But because of the rain, I went late waiting the rain stop. my friends had gone already. than at 8.00 pm I left riding my Vespa there. We were planning to hang out, cause we've not met our friend Ughie that have gone to Malaysia for work for about 6 months at previous. After from the PlaGo we went to a cafe near St, Boromeus hospital to have some eat. One of my friend, that come with us suggest us to eat at that place. so that guy, whom I didn't know the name, went with his motorcycle.

So there were 2 motorcycles go to the place. The others went by public vehicle (angkot, lah...) The only one who knew the place was just the person who suggested it. I didn't noticed and followed him carefully, so we run in a line. When it was the time to turn right, I got a little confuse was he really to go right or not, cause I haven't known the place. So we run in a line. From the left side of the road I go to the right side. I was running slowly, but suddenly a motorcyle from behind us run in fast speed. It was a drizzly night, so the road was slipping. The motorcycle rider didn't have enough distance to brake when he saw me in front of him. So finally, the motorcycle hit my Vespa... Ouch... I felt a big crash at my back even though I was ok. Both, I mean three of them: the motorcycle, the rider, and the passenger, that was his wife I supposed.

I turn my motorcycle around to the left side. When I did it, I couldn't change my gear. It was stuck.. The rider and passenger of motorcycle who hit me stood up and bring his motorcycle to the side of the road, near me. we just had a little talk that I told him that we should be careful at the slipping road, it was a rainy day. My friends were coming to me to see after the got out of the angkot.

Well, actually I wanted to ask some recompense because when I looked at my engine, the bowl of the gear had been crack--a big crack and the upper side was bent. But when I realized that the passenger was a woman I thought I couldn't do it. I just hope that the man would be aware for next time. When I dismantled the upper side of the gear that I hope the bend that made the gear stuck, both the man and the passenger have left me with my friends.. I actually didn't hope that (damn..)

When I finished dismantled, I can carry my motorcycle by propelling it to the cafe. Fortunately it wasn't a long distance from the main road of Dago. I took a while resting my heart that was beating hardly. While we eating Ughie gave me some souvenirs that he brought from Malaysia. It was nice, a transparent glass with Twin Towers in it, and a pendant for key (it's called gantungan kunci in Indonesia. I don't know the English). Well, it cheered me up for a bit. After we finished eating, I tried to turn my motorcycle on. It took a little strive to turned it on, Alhamdulillah... Thanks God, It was running.

So finally I could go home. I took Ferry to Simpang Dago where he would took angkot from there, and then I went home.. fiuhhh... The night was a beating my heart... I came home in a fully carefully... After I arrived at home, the battery of my cellphone was running out. When I tried to charge it, the charger couldn't work. It broke down (Damn...) another problem when I was about to sleep... ;(

Then I thought... Did all of these things because I've killed the rat at the noon???

Crash again...

Another airplane accident happened again on 7th March 2007. the Garuda Indonesia Airplane got a crash in Adi Sucipto airport In Jogjakarta. It was happened when the plane was just about to landing. Then, without any known things what made this happened.

at least 21 people was dead for this accident, out of 140 passengers on the plane. so many disaster and accident have been a so frequent thing in Indonesia.

the day before an earthquake also occured. I'm really sorry for these disaster.. ;(

Disco Lazy Time

the song I think a little represent my lazyness for posting my blog.. I don't know. my mood is not good for recent time. so I haven't post anything.

but now, I'm back. I know I have to do something seriously, on anything I do.

disasters come again to Indonesia recently, I'm gonna list them. the year of 2007 was opened by AdamAir accident.
- AdamAir airplane aciddent, the passengers still haven't been founded till now
- KM Senopati accident
- floods in Jakarta
- KM Levina accident
- AdamAir crash again at Ir. H. Djuanda airport in Surabaya
- cyclone in Jakarta, perhaps can visit all Indonesia too
- Earthquake in Sumatra Barat. 5.8 in Richter scale
- Landslide in Manggarai, Nusa Tenggara

maybe I haven't mentioned completely. but that was have been too many for two months. we have to contemplate...

My New OS

Hey guys, I've installed a new OS yesterday. The New Solaris 10. wow.. i was very pleasure when I got it last friday. it was the day i came back from Jakarta to Bandung. the day when I left Jakarta, it got flooded all parts of the city ;(

I got the cd originally from Sun Microsystems. they gave the new Solaris 10 DVD for free. there are three DVD that they gave:
1. Solaris OS for x86/64
2. Solaris OS for SPARC architecture
3. Developer Tools DVD

I just curious, wanna feel how's the taste of Solaris. it's all about unix isn't it. I wanted to taste it in my own notebook.

so... it wasn't easy enough to install it. there are few (may be many.. ;)) that I haven't got it. so the installation didn't get smooth, but I just installed it once. 'cause fortunately I didn't have to reinstall it if i got error nor not installed completely. if the installation got error, it would help us to recover any files that needed to be fixed.

I had a "little" difficult for the GRUB. the Solaris only could detected the windows. not my Gentoo. after a little try modifying the menu.lst file, I didn't make it. so I did a little browse to find out. in the middle of browsing seeing any examples of menu.lst file. i just realize that the configuration of the menu.lst file between linux and Solaris are not the same way. so I added the new line to boot my Gentoo. and then... guest what.. it can boot all of my OS now... wooww...

now, this is the list of OS that are installed in my notebook;

1. /dev/hda1 - Mi**os**t Win***s
2. /dev/hda3 - The Solaris 10
3. /dev/hda8 - Gento0 distribution

well, there's one more problem I haven't got the chance to try, is to try boot from the GRUB of my Gento0...

Flooding

The flood has come again. it attacks all part of Jakarta. not even in Jakarta, it also comes to other places in Indonesia, one of them is Jambi.

This disaster is most about human faults. people often just throw trash not in the right place. they throw garbage to the river, the sewage, even in the pool. the Jakarta gov also always did the wrong way. they evicted the people from their houses by the reason of sight irk. than they trade the land to the real estate developers to make buildings, skycrapers. isn't that really a fool thing that they did?

not also that, they also build and build again. it makes jakarta don't has any absorp area again. so if the big flood comes, the town won't be able to hold any water come. then it became the flood.

the jakarta citizens (the riches) bought houses in upper town like bogor, puncak, and the surroundings area that is higher land than jakarta. so they also can't absorb water if the rain come.

so, it's all about human faults. the jakarta gov never learn from their mistakes in the past. they just do and do it again.

we should aware about our neighbor. we should keep it, because the earth is the place where we live. where ever we are.

Chauu...

rawing

today is the day when i feel i don't get anything for my study pursuit. the one (the only one of three persons) i met didn't want to sign the check paper.

he said, "let the other(s) first". then I said, "but sir, the other(s) aren't at their places".

so my paper became raw again..;( i'm feeling sad. I should finish this fast and want to go home.. I miss my family at home. and of course.. the "other" family.. :)

well, let's see the situation tomorrow. i hope they will be at their room tomorrow, so I can get them and asking for their signs.. ;)

Ya Allah, please give me strength and hard motivation.. :D

Racing with the time

This week has become a worrying week again for me. lots of things that i want couldn't happen at the exact time. i really wanna go home. i really miss my family, also there's someone that really miss me too...

i'm hopping i can finish all the things that should be finished this week. Would you wish me luck?! :)

Stressing Exam

Wow.. it was the hardest exam i ever pass. so much tasks that i had to do, then i got to gave it at the exam schedule. but the hardest thing is the date time is near one to each other. one day after another.

So... Wooow... again.. :) the hardest week has passed me, even though I don't know when I can get it again.. ;) 'cause every man must have hardest thing in their life..

well, brothers and sisters. for you who haven't notice about this blog. it's has been changed into the new version of blogger. i did not post for a little while, all the things I did before was just moving the posts from my old blog to the new one. I'm preparing the design that comport with my (new) blog. but especially in posting layout. I'm not a good visual designer... ;(

well.. i'm trying to having a little holiday first now.. ;) have a nice day... ;)
