Here are some more attemps via the New Plugger How to Wiki
ome more attempts:
The DHCP client is configured to ignore any DNS servers returned by the DHCP server
and use 127.0.0.1 instead, while there is no local DNS server.
Consequently, you won't be able to connect to any hosts by name until you fix this.
In order to fix it: Edit /etc/dhcp3/dhclient.conf and comment out or delete the line
"supersede domain-name-servers 127.0.0.1;".
--- My version of ubuntu 9.04 does not have the "supersede..." line in it so I just
Run "dhclient eth0".
Try "ping kernel.org" - it should work.
I go instead of this for these two operations above:
root@ubuntu:/etc/dhcp3# dhclient eth0

I think "unknown Host" is a not working condition...
