Hello Dep et al,


Surely, it's not related to Trinity.
I observed such behavior on my Ubuntu 12.04LTS when switching,
for instance,between wired and GSM Internet connetions.
Network Manager is the troublemaker, most probably.

Don't bother yourself with warning saying "Do not edit".
If you need, just insert manually into resolv.conf file
your nameservers and restart networking:
	/etc/init.d/networking restart
You should be O.K. then.
