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 Block
{code 'Enter'
  • heading
Code Block
'ctrl' AND '1' XOR '2' XOR '3'
  • bullet list
Code Block
'shift' AND 'ctrl' AND 'b'
  • bold, underline, italic
Code Block
'ctrl' AND 'b'
'ctrl' AND 'u'
'ctrl' AND 'i' 
  • save
Code Block
'ctrl' AND 's'

 

Problems encountered after installation of debian

On start and halt

PROBLEM:

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

SOLUTION:

Code Block
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

Code Block
apt-get install xorg

Install Gnome

Code Block
apt-get install gnome-core

to test the installation:

Code Block
starx

change the resolution

Code Block
CTRL + ALT + '+'  and CTRL + ALT + '-' 

screen the available resolution and change it

Code Block
xrandr -q
wrands -s resolution 

 

Install a display manager

Code Block
apt-get install gdm

to start it

Code Block
gdm

 

Install proprietary graphic card drivers:

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

Check the kernel version

Code Block
uname -r

Install the kernel header and link it to the linux file

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

Install the compilers

Code Block
apt-get install gcc g++

 

 For the nvidia cards

Download the latest drivers from the nvidia website.

Stop gdm (might need a kill)

Code Block
/etc/init.d/gdm stop

Install the driver

Code Block
sh NVIDIA...

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

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

To remove the logo in xorg.conf

Code Block
Option "NoLogo" "1"

Code Block

Code Block
chmod +x /root/scripts/amanda-backup 

Recover (example for /etc)

In order to be able to run a recovery add the following line to /etc/amandahosts

Code Block
localhost root amindexd amidxtaped

Go to the /etc folder

Code Block
amrecover sam-daily
listhost
sethost  debian-server-test-sam.bluelight.av
listdisk
setdisk /etc
cd (folder name - ls works too)
add (name of the folder to recover or * for everything)    
extract
exit

 

...

-c "touch /var/lib/amanda/sam/tapelist"

label the tapes

Code Block
for i in `seq 30`; do su backup -c "/usr/sbin/amlabel sam-daily SAM-$i slot $i"; done

/root/scripts/amanda-backup (after creating the folder)

Code Block
#!/bin/bash
#mount ${DISK} /mnt/backup
su backup -c "/usr/sbin/amdump sam-daily"
#sleep 5
#umount /mnt/backup
exit 0
Code Block
chmod +x /root/scripts/amanda-backup 

If the backup is restored from an external drive:

    • make sure you have /etc/amanda and /var/lib/amanda on the external drive
    • copy these 2 folders to the system to restore
    • mount --bind the folder containing the vtapes to the folder on the system which supposed to have the vtapes (cf /etc/amanda/sam-daily/amanda.conf)
    • follow the steps above
