Debian Wheezy 7 installation guidelines¶

The distribution GNU/Linux Debian Wheezy has been chosen for several reasons: long term support (until 2017), active community, stable packages. We consider an installation performed thanks to a Debian Live support.

During the installation process, the following partitioning is recommended:

primary SWAP, 1 GB;
primary ext4, /, 40 GB;
secondary ext4, /home, (remaining space).

Once the installation is performed, it is assumed to realize the following operations using a root shell. If necessary, a proxy will be set through appropriate environment variables:

export http_proxy=http://host:port
export https_proxy=http://host:port

Additional packages installation¶

Edit /etc/apt/source.list and add contrib and non-free targets in order to obtain the following.

deb http://ftp.fr.debian.org/debian/ wheezy main contrib non-free
deb-src http://ftp.fr.debian.org/debian/ wheezy main contrib non-free

deb http://security.debian.org/ wheezy/updates main contrib non-free
deb-src http://security.debian.org/ wheezy/updates main contrib non-free

# wheezy-updates, previously known as 'volatile'
deb http://ftp.fr.debian.org/debian/ wheezy-updates main contrib non-free
deb-src http://ftp.fr.debian.org/debian/ wheezy-updates main contrib non-free

Update the package list.

apt-get update

Install the following additional packages.

apt-get install texlive-full texstudio auctex wireshark filezilla \
openssh-server vlc octave-communications subversion git thunar-vcs-plugin \
xfce4-goodies arandr libreoffice-l10n-fr flashplugin-nonfree evince xournal \
eog python-matplotlib python-scipy ctags doxygen ntpdate libpam-ldap nscd screen \

Services configuration¶

Sudo configuration¶

Any modification to the sudo configuration should be performed through the following command.

visudo

Append the following line in order to preserve environment variables http_proxy and https_proxy through sudo.

Defaults env_keep += "http_proxy https_proxy"

Enable LDAP authentication¶

In order to authenticate through the network using LDAP, it is necessary to install the following package.

apt-get install libpam-ldap

At the end of the installation, an interactive configuration process is triggered. It can called back using the following instruction.

dpkg-reconfigure libpam-ldap

Add the ldap module to the first three instructions in /etc/nsswitch.conf in order to obtain something like this:

passwd:         ldap compat
group:          ldap compat
shadow:         ldap compat

In case of successful login, add the following line to /etc/pam.d/common-session in order to create automatically the home directory.

session required    pam_mkhomedir.so skel=/etc/skel umask=0022

Finally, restart the nscd service.

/etc/init.d/nscd restart

Enable NTP¶

In order to synchronize the real time clock through the network, install the following package.

apt-get install ntpdate

If applicable, add local NTP servers to /etc/default/ntpdate. Then trigger the first synchronization.

ntpdate-debian

Notice that NTP synchronization is performed at each network interface bootup.
