When I edit /etc/resolv.conf, it is overwritten right away with the old configuration. How do I really change the nameserver on Ubuntu Server 9.10?

Here is how I do it:

  1. Backup your resolv.conf

    sudo cp /etc/resolv.conf /etc/
  2. Edit /etc/dhcp3/dhclient.conf:

    sudo gedit /etc/dhcp3/dhclient.conf
  3. If there are any nameservers, write them down for future reference.

  4. Replace the reference line, or add:

    prepend domain-name-servers,;
  5. Save and exit!

  6. Restart any Internet clients and services

  7. Test your new settings.

This should work in 9.10 just fine.

Why did you edit out a working DNS server, for one that doesn't exist? – Jeffrey Aylesworth Feb 24 '10 at 21:06
Me? Well I'd figure you already had your own in mind :-\ – Urda Feb 24 '10 at 21:51
