Installing Debian Etch from the Net


Here's a quick guide on how to install Debian 4.0, a.k.a. "Etch" from the 150MB NetInst CD and fetch the rest of the files from the Net.


  1. Burn the ISO image, boot with it and follow the install procedure
  2. Once the OS is installed, run "apt-get update ; apt-get upgrade"



The server did detect the USB pen drive, but didn't auto-mount it. To do this, edit /etc/fstab, and add the following, using TABs in between columns:

/dev/sda1    /mnt/pen    vfat    noauto,users    0    0


alias ll='ls -al --color=auto'


  1. If you chose to install the basic configuration, SSHd should not be installed : apt-get install ssh. Once it's up and running, you can connect to the server from a remote host if you need to


CTRL-Z to cancel?

  1. ll : uncomment /root/.bashrc
  2. No mouse
  3. USB KVM
  4. Beep : editing /etc/inputrc to uncomment those two lines stops the beep in bash when using the backspace key while in column 1, but doesn't stop vi/vim from being when using either the left arrow while in column 1 or hitting the ESC key:

    set bell-style none
    set bell-style visible
  5. Bad backspace key in vim: edit /etc/profile, and add the following:

    stty erase ^H
    alias ll='ls -al --color=auto'

  6. While in vi, arrow keys show ABCD : use vim
  7. Grub : no keyboard

User-friendly text editor




Packages to remove

  1. apt-get -s remove portmap
  2. uninstalling packages leaves scripts and symlinks under /etc/init.d/ and /etc/rc3.d/


vi /etc/apt/sources.list

Dpkg vs. dselect vs. apt-get

dpkg  is  a  tool  to install, build, remove and manage Debian packages. The primary and more user-friendly front-end for dpkg is dselect. dpkg can be also be used as a front-end to dpkg-deb.

apt-get is the command-line tool for handling packages, and may be considered the user's "back-end" to other tools using the APT library. Several "front-end" interfaces exist, such as dselect), aptitude, synaptic, gnome-apt and wajig.

apt-get update vs. upgrade

"update" is used to resynchronize the package index files from their sources. The indexes of available packages are fetched from the location(s) specified in /etc/apt/sources.list. "upgrade" is used to install the newest versions of all packages currently installed on the system from the sources enumerated in /etc/apt/sources.list.

Windows-like text editor

SetEdit : OK

MCEdit : OK

ne : OK (F1 for menu)

Jed : OK


Le Editor : only old version in Debian repository

Managing packages

To search repositories for new software to install:

apt-get update ; apt-get search

apt-cache search "*emacs" = BAD???
