Static IP to DHCP on Debian 3.1


I have a laptop running Debian 3.1 that was assigned a static IP address when I was using it at home. I've moved off to college and now I need to have it assign an IP address automatically through DHCP.

I don't yet have accesss to the internet, but once I do, I'd like to know how to properly setup DHCP. So my question is, what is the proper way to do this? Do I need to remove my old /etc/resolv.conf? What configuration files do I need to edit to have my DHCP client start at boot time?

Thank you in advance for your responses, and please excuse the fact that I have very little knowledge of networking on Linux.

You might need to change your /etc/resolv.conf, you will have to add a line like:
Code:
nameserver 192.168.0.1
(where the ip is the ip of the router or server). You will need to edit /etc/network/interfaces aswell. It should have these lines in it:
Code:
auto eth0
iface eth0 inet dhcp
Then restart the network:
Code:
ifdown eth0; ifup eth0
That is how I normally restart the network, but there might be another way. Hope this helps,
Tom

edit: Just thought, don't you need to install some DHCP client programs? And if the network starts at boot, then it should use DHCP at boot aswell.
