How to change DNS Name Servers in Linux?

Posted on: 23 04 2013 by Panta in Linux

The file to change DNS nameservers in Linux is /etc/resolv.conf:

cat /etc/resolv.conf

For example, if you want to set up Google public DNS, open the file:

sudo nano /etc/resolv.conf

And add the following lines:

nameserver 8.8.8.8
nameserver 8.8.4.4

Save the changes with Ctrl+O and Enter, then Ctrl+X to exit from nano editor.

Restart the network:

sudo /etc/init.d/networking restart

Or, in Network Manager, go to Edit->IPv4 Settings tab, choose Automatic (DHCP) addresses only and add DNS IP addresses.
