IISERK Haringhata Campus

Making a post after quite a long time. In the meantime a lot of things have changed here. This is my first post after moving to the Haringhata Campus. From the hustle and bustle of Kolkata we were suddenly "teleported" to the calm and serene atmosphere of Haringhata, quite a bit jump it was.
The location didn't quite disappoint me, though many "mall hoppers" and a few "privileged ones" (their homes are in Kolkata) who earlier could slip into the comfort of their homes every weekend easily were unhappy, it has become a bit more difficult for them to do so now. However one thing that I really miss is the 2Mbits connection. There is no broadband connection yet in the hostel, and currently we are trying hard to manage using a 17KBytes Wireless Dialup connection over CDMA. There is little chance of getting any high speed connection in this remote location. The administrative building does have a decent leased line, but it is at a few minutes of walking distance from the hostel making it difficult to land up there late at night.
Apart from this annoyance, life is quite peaceful here. Being located far from the city, the night sky remains glare-free, which provoked a few of my friends to plan to buy a telescope for star-gazing. I am too looking forward for this.

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 Open…

Some more fun with SSH port forwarding and socks proxy

Few days ago I made the following post:

Prologue: Our Institute has several nice Dual Core Machines deployed for the students. Unfortunately the machines are behind a NAT with no port forwarded for external SSH access. Student's hostel is a bit far off from the computational centre. As such if someone felt the need of accessing the machines during non-office hours, it was a wee bit difficult. The sysadmin would not have agreed to forward any ports. Something had to be done....

SSH has a very useful feature - Remote and Local Port Forwarding. We have an old rickety PIII running Ubuntu 8.04.1 in the Hostel, it is connected to the net and is accessible via SSH from the internet. Using a tiny little shell script running on one of the machines in the Institute, I managed to make the old PIII an intermediate gateway for gaining SSH access to the Institute's machines from anywhere in the internet. The script is of few lines, but nevertheless powerful enough to serve our purpose.


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
