DNS server info not saving between reboots

For some reason the network configuration > Hostname and DNS Client > DNS servers isn't persisting true reboots, so i have to enter localhost (127.0.0.1) as a dns server after every reboot.

any ideas on why this is happening? ... other changes are saved. the server is running ubuntu 10.04.

Howdy,

If you're using DHCP to obtain your IP address, DHCP may reset /etc/resolv.conf each time it obtains an IP address. Editing the dhclient config file in /etc, you can set it to not do that.

There's a few ways listed here for accomplishing that, I suggestion option #3:

Well, not a DHCP server, but a DHCP client -- does your server have a static IP, or does it obtain it's IP address via a DHCP server?

Is there any chance you could post your /etc/network/interfaces file?
