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.
