Setting up a Debian repo in LAN

It was really a nice experience going to MES College Of Engineering, Kuttippuram last week to attend Debian Mini Conf 2011. Met friends, made new friendships and learned many new things from there. Thanks to Jishnu ettan, for giving me a 50GB Debian repo that contains all the packages of squeeze of both i686 and amd64 architectures. Today, I will explain how to set up a Debian repo (squeeze) so that it be can shared over LAN.

First, run terminal and switch to root user.

$su

If you have the repo as an ISO image file, we need to mount it to a directory. The following command does that:

#mount <path-to-iso> <path-to-mount> -o loop

Edit /etc/apt/source.lst and add the repo we mounted. Append the following line to the file:

deb file:///<mounted-path> squeeze main

Update the package list:

#apt-get update

We are going to share the files using http, hence we need a webserver. To install apache:

#apt-get install apache2

Make a symbolic link of <mounted-path> in /var/www

#ln -s /var/www/repo <mounted-path>

Done! Now add this machine as a repository in other Debian systems in LAN, edit /etc/apt/source.lst to:

deb http://<ip-of-server>/repo squeeze main

The same can be done using a FTP server. All you have to do is to make the symbolic link in FTP’s configured path and use ftp:// instead of http:// in /etc/apt/source.lst. Thank you ๐Ÿ™‚

Connect TATA Docomo Internet in Ubuntu 9.04

It’s wonderful to see people browsing in their mobile phones at work places and while they travel. Many Telecom companies provide cheap GPRS / EDGE based internet connectivity which can also be connected to a computer. Here, I will explain how to connect TATA Docomo Internet service in your Ubuntu machine.

Step 1 : Connect your phone and create a new ‘Mobile Broadband’ connection from the appeared wizard. You can Select ‘Airtel’ in ‘Service Provider’ which we will change to suit Docomo Internet.

Step 2 :ย  Change the ‘Name’ in ‘Summary’ page to “Docomo Internet”

Step 3 : Go to System –> Preferences –> Network Connections, Under the “Mobile Broadband” tab, select “Docomo Internet” and click on “Edit”.

Step 4 : Change APN to ‘ TATA.DOCOMO.INTERNET ‘ without quotes. Also, Under “IPv4” tab, select “Method” as “Automatic (PPP) addresses only”. We will give Open DNS as DNS servers, ie, in the “DNS Servers” box, give ‘208.67.222.222, 208.67.220.220’ wihout quotes.

Done! Now click on the antenna icon in system tray, select “Docomo Internet” from the list – You are connected! Best of Luck ๐Ÿ™‚
