Changing DNS of my Ubuntu server

This is related to my September 2010 post on how to configure a static IP address for a computer.
I had to revisit that post and change the IP address again today, after having bought a new router with a new LAN configuration.

Here is the how-to for specifying an explicit DNS server, to guarantee that the Ubuntu SSH server will have Internet as well.

Edit this file in the terminal:

sudo nano etc/dhcp3/dhclient.conf

Changes:
1. Remove the "domain-name-servers" from the request directive.
2. Modify the line:

prepend domain-name-servers 127.0.0.1;

by changing 127.0.0.1 to the DNS server of your Internet connection.
For my case, using Sun Broadband (Huawei usb modem), it was:

prepend domain-name-servers 202.138.128.50,202.138.128.54;
