Set DNS name server on Ubuntu 12.04 LTS

If you wish to change the dns nameserver information in ubuntu 12.04, you have to use the file /etc/network/interfaces instead of /etc/resolv.conf.

Edit /etc/network/interfaces and append or replace the following line to set your dns server :
dns-nameservers 1.2.3.4  5.6.7.8
And optionally this one to specify the domain to be append when you request a non fully qualify name :
dns-search foo.org bar.com
