Change dns nameserver - Ubuntu 9.10

Question

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?

Answer 1

Here is how I do it:

1. Backup your resolv.conf

   sudo cp /etc/resolv.conf /etc/resolv.conf.auto
   

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 1.2.3.4,4.3.2.1;
   

5. Save and exit!

6. Restart any Internet clients and services

7. Test your new settings.

This should work in 9.10 just fine.
