Adventures with IPv6

I spent the past couple of days, tinkering with an old Linux box, trying to set up a fully functional IPv6 network, complete with an IPv6 webserver, nameserver, mailserver, network router and firewall.
The job is partly done.
The nameserver, webserver, network router and firewall are working quite well.
The website can be accessed here http://oak.ipv6.iiserk.net(Provided you have IPv6 connectivity). It runs on a rickety PIII running Ubuntu 8.04.1 and connected to my friend's home ADSL connection. Power failure are quite a common affair in our region (in almost the whole country, to be honest!) and there is no power backup for the server, so if it appears to be down, kindly check back sometime later.
The nameserver ns1.ipv6.iiserk.net manages the DNS records for the subdomain ipv6.iiserk.net.
I hope to get the mailserver up and running quite soon.
I'll also come up with a detailed documentation on how I got the things running, sometime in the near future.
Anyway for this half-crappy IPv6 implementation, I got this from Hurrican Electric Internet Services:

(It is a certificate, but removed the JScript, as it was causing the page to load slowly)
It started with "newbie" level, and is improving!
More on IPv6 soon... may be in a day or two.

Force an application to use VPN, using iptables in Linux

Enforcing an application, for example a torrent client like Transmission , to always use the VPN interface or any particular network interface for that matter, is trivially simple using iptables on Debian, Ubuntu or any other GNU/Linux distro. Personally, I am running Debian Sid on the Raspberry Pi . Occasionally I use it for downloading files ( legal stuff, seriously, believe me :D  ) using Transmission Bittorrent client over a VPN connection. Sometimes it happens that the VPN connection fails and doesn't reconnect for whatever reason and Transmission continues pulling stuff directly over my internet connection, which I would like to avoid. Fortunately it is very straightforward to enforce rules based on application owner UID. Transmission runs under the owner debian-transmission in Debian (use htop to check this) and the following two lines of iptables ensures that any process with owner having UID, debian-transmission , will not use any other network interface apart from the...

Rendering LaTeX in Blogger.

Rendering LaTeX in Blogger is pretty easy thanks to the JavaScript LaTeX equation render engine from http://www.yourequations.com . To enable LaTeX rendering go to the Blogger Dashboard --> Layout --> Edit HTML . Then add the line <script> type="text/javascript" src="http://tex.yourequations.com/"></script> <script type="text/javascript" src="http://tex.yourequations.com/"></script> just before <body/> . Half the job is now done. Then, for example to render: \int_{0}^{\pi}\frac{x^{4}\left(1-x\right)^{4}}{1+x^{2}}dx =\frac{22}{7}-\pi Use the code: <pre lang="eq.latex"> \int_{0}^{1}\frac{x^{4}\left(1-x\right)^{4}}{1+x^{2}}dx =\frac{22}{7}-\pi </pre> The LaTeX code will now be displayed as: \int_{0}^{1}\frac{x^{4}\left(1-x\right)^{4}}{1+x^{2}}dx=\frac{22}{7}-\pi Ofcourse Javascript needs to be enabled in the Browser for the renderer to work.

Raspberry Pi -- Installing Samba (Windows Share) File server

Having successfully run Debian Wheezy on my Raspberry Pi, I went forward with my initial idea of setting up a low cost power efficient file server for accessing my external hard disks from my Windows7 desktop, HP-Mini running Ubuntu and Mac Mini running OS X Lion (yeah I do like bragging about my machines :D ). This turned out to be pretty straight forward. As expected, the external Seagate USB disk immediately got recognized and appeared as /dev/sda [ 579.948350] usb 1-1.2: New USB device found, idVendor=0bc2, idProduct=3001 [ 579.948384] usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 579.948405] usb 1-1.2: Product: FreeAgent [ 579.948421] usb 1-1.2: Manufacturer: Seagate [ 579.948447] usb 1-1.2: SerialNumber: 2GEX323R [ 579.967638] scsi0 : usb-storage 1-1.2:1.0 [ 580.970520] scsi 0:0:0:0: Direct-Access Seagate FreeAgent 102D PQ: 0 ANSI: 4 [ 589.142942] sd 0:0:0:0: [sda] 1953525168 512-byte logical blocks: (1.00 TB/931 GiB) [ 589.1446...
