I've read a few posts now about DNS issues and Ubuntu 8.04 as well as experienced my own problems:

http://www.zimbra.com/forums/migrati...migration.html

For me the problem appears as a strange "localhost" resolution error
After three nights of trial and error I believe the problem to be the Multicast DNS discovery service.
Specifically, the order of precedence in the /etc/nsswitch.conf if MDNS is enabled
in Ubuntu 6.06 the hosts line is:
Code:
hosts:          files dns mdns
in Ubuntu 8.04 the hosts line is:
Code:
hosts:          files mdns4_minimal [NOTFOUND=return] dns mdns4
What I have read point to changing the hosts line to match that of Ubuntu 6.06


does anyone have the ability to test my theory before I spend another 6 hours trying my migration to 8.04 again this evening
