deb http://mozilla.debian.net/ squeeze-backports icedove-release

#virtualbox

deb http://download.virtualbox.org/virtualbox/debian squeeze contrib non-free

and my apt preferences file is:

#for squeeze updates

Package: *

Pin: release a=stable-updates

Pin-Priority: 1010

#for stable

Package: *

Pin: release a=stable

Pin-Priority: 1001

#for squeeze backport

Package: *

Pin: release a=squeeze-backports

Pin-Priority: 700

#for icedove

Package: icedove

Pin: release a=squeeze-backports

Pin-Priority: 1001

#for iceweasel

Package: iceweasel

Pin: release a=squeeze-backports

Pin-Priority: 1001

#for testing

Package: *

Pin: release a=testing

Pin-Priority: 650 #450

#for unstable

Package: *

Pin: release a=unstable

Pin-Priority: 600 #400

I have kept lower priorities in preference for testing and unstable because they are not recommended for stable production system and may crash your system.

After setting preferences, you need to put ‘-t {repo type}’ for installation e.g.,

$ apt-get install -t stable mypkg

Debian4Engr Series: 02 Recommended Linux Partition

Published by in Debian4Engr, How to on December 10th, 2011 | No Comments »

During installation of Debian Linux, you are required to enter partition scheme. The easiest way is to use entire disk and recommended partition or you can decide yourself the partition. One of helpful detail of partition is given below:

swap = 2GB
file type for rest of partition = ext4
/ = 6GB
/boot =200MB
/opt = 10GB
/srv = 3GB
/tmp = 6GB
/usr = 10GB
/usr/local = 10GB
/var = 5GB
and finally for /home = rest of space left (but atleast 10GB).
This partition is on Logical Volume Manager – LVM. You can edit each partition later using GParted Live CD.

Note: This recommended partition is for end user’s laptop and desktop. For servers, /srv partition should be big enough for running services and /var partition must also be adjusted for maintaining log files.

For More info:

You can find more information about swap size from: NixCraft or Linux.com. The details on each partition is given in NixCraft, LinuxPlanet, Debian.org and on LinuxQuestions.

For partitioning multiple disks, guide can be found on tldp.

To check existing partition, use fdisk, palimpsest and baobab – Gnome Disk Usage Analyzer.

Debian4Engr Series: 01 Before Installation

Published by in Debian4Engr, How to on December 10th, 2011 | No Comments »

Debian is a free operating system (OS) for your computer. Debian GNU/Linux provides more than a pure OS: it comes with over 29000 packages, precompiled software bundled up in a nice format for easy installation on your machine. Read more…

01 Before Installation

  1. Debian Linux is installed on most of the desktops without any issues. If you want to install Debian Linux on laptop then check hardware support from http://linux-laptop.net/ or http://bing.com/

  2. If your laptop not found in the list then still you can try it.

  3. Run live cd mode to check keyboard layout, hardware compatibility, installed software and desktop environment.

  4. To get used to with environment of Linux and its desktop like gnome or kde, install it in virtualbox.

  5. Debian Linux is recommended for advance Linux users. It is recommended to try easy distro like Ubuntu before and have some know how on basic Linux commands and tasks.
