1. Assignment: Install a debian ssh server on a VirtualBox and access to it

config apt-cacher 192.168.10.1 port 3128

sed -i 's#http://#http://192.168.10.1:3142/#g' /etc/apt/sources.list 

install emacs

sudo aptitude install emacs

install config openssh server and make it work

eval `ssh-agent`
exec ssh-agent bash (if ssh-add is not working)

add sam_sshkey.pub to .ssh/authorized_keys

add to /etc/ssh/sshd_config:

AllowUsers xxx

changed in the same file:

PasswordAuthentication no
PermitRootLogin no

If ssh doesn't work check the grp and own of .ssh/authorized_keys

install bash completion

aptitude install bash-completion

add the following to ~/.bashrc or ~/.bash_profile

if [ -f /etc/bash_completion ]; then . /etc/bash_completion fi

Document the work done

Well, that's kind of done but the editing interface of the wiki is not yet clear to me. Few shortcut:

• create a code box:

{code 'Enter'

• heading

'ctrl' AND '1' XOR '2' XOR '3'

• bullet list

'shift' AND 'ctrl' AND 'b'

• bold, underline, italic

'ctrl' AND 'b'
'ctrl' AND 'u'
'ctrl' AND 'i' 

• save

'ctrl' AND 's'

...

Problems encountered after installation of debian

On start and halt

PROBLEM:

exim paniclog /var/log/exim4/paniclog has non-zero size, mail system possibly broken

SOLUTION:

rm /var/log/exim4/paniclog

need to start the network manually dhclient eth0

PROBLEM: when auto eth0 added to interfaces. Nfs interfaces gets stuck on boot.

SOLUTION: there was no 'auto lo' in /etc/network/interfaces. That added plus 'auto eth0' makes it work.

2. Assignement: Install a graphic interface on Debian installation

Install Debian with nothing else than the minimum (except for laptop)

Install XOrg

apt-get install xorg

Install Gnome

apt-get install gnome-core

to test the installation:

starx

change the resolution

CTRL + ALT + '+'  and CTRL + ALT + '-' 

screen the available resolution and change it

xrandr -q
wrands -s resolution 

Install a display manager

apt-get install gdm

to start it

gdm

Install proprietary graphic card drivers:

If the kernel isn't compiled you need to install the kernel headers.

Check the kernel version

uname -r

Install the kernel header and link it to the linux file

apt-get install linux-header-...
rm /usr/src/linux
ln -s /usr/src/linux-header-... /usr/src/linux   

Install the compilers

apt-get install gcc g++

 For the nvidia cards

Download the latest drivers from the nvidia website.

Stop gdm (might need a kill)

/etc/init.d/gdm stop

Install the driver

sh NVIDIA...

Don't download the kernel interface. Ask for a compilation of a new interface. Start xconfig ans restart gdm

nvidia-xconfig
/etc/init.d/gdm restart 

To remove the logo in xorg.conf

Option "NoLogo" "1"
