[Christoph Schneeberger]

Ken, Steffan,

Sorry for my late reply. There are 2 parts in the hostfile, each being 
modified by another piece of code. My own problems on VPS lie mostly 
within the part that parses ifconfig (the part with "### Begin - Nuonce 
hosts Fix" in the hosts file), the responsible script for this is 
/usr/sausalito/constructor/base/vsite/fixhosts .
However the part that messes it up for you seems to come from the script at
/usr/sausalito/handlers/base/network/etchosts.pl .
This script uses only values from CODB, so it seems that the old IP you 
see is buried somewhere in CODB and results in the wrong results in 
hosts file.

Beside checking the GUI for i.e. Sites that still have the old IP and 
removing them to make sure CODB looses the old IP I can only give the 
following workaround until somebody with more and deeper knowledge of 
CODB chimes in:

Fix the hosts file in question based on a working template from another 
VPS. Once you saved it corrected and hostname -f returns what you think 
it should lock the file against being recreated or modified with the 
following command:

chattr +i /etc/hosts

Now you can safely reboot without loosing your corrected host settings, 
it will result in a few errors on startup but will work fine.

Once there is a fix or you want to make the hosts file writable again, 
just use

chattr -i /etc/hosts


Sorry for not being of more help, but this should help you at least to 
feel a bit more comfortable for the season holidays ;-)

Hth,
Christoph
