How to set DNS servers? How to stop auto change of DNS servers?
 

Ubuntu 8.04

When I first log in as a user, there is no problem connecting to the internet. Then, after a short while, some type of auto-configuration change happens, and the DNS nameserver is changed to a .1.1, and I can not connect anymore.

Then, I have to go to the Network Tools, using the administrator password, and manually type in the two DNS servers.

1) How can I keep it from trying to automatically change the DNS servers while I am on the internet?

2) What is the command line way to set the DNS servers? The Network Tools is a GUI run tool.

3) Why is it automatically trying to change the DNS servers?
