Switching to Dynamic IP from command line

[wibbleberry]

I have an ubuntu server set up without a GUI and need to switch it from static to dynamic IP from the command line. I cannot download any packages as it was configured on a different router to the one I am using now. If it is more complicated than a few settings changes in config files I will have to make other arrangements. Anyone have a set of commands that can do this?

# The loopback network interface
auto lo
iface lo inet loopback

auto eth1
iface eth0 inet manual

Change the word "manual" to "dhcp" under the interface you would like to change in the file /etc/network/interfaces

Brilliant. Had to go brush up on vi. Ta vm.

Thank you for this! I changed mine over to static ip and lost my internet connection, switching back to dynamic helped.
