How to change IP in Ubuntu without GUI?

[Red Squirrel]

When I first setup my HTPC I set a static IP using the GUI, now that it's setup it has no keyboard and mouse, just a remote, so short of ripping it out of the cabinet and hooking it up to my workbench, I do not have GUI access to it.

When using the GUI, where is the information stored? Is it a file I can just go edit, or is it deep embedded somewhere in a non human readable format? I looked at /etc/network/interfaces but it has nothing of interest in it. Same with /etc/networks. No IP info or anything. Any other place I should check?

/etc/sysconfig, I think. Or use the ifconfig command.

In RH that's how it is (/etc/sysconfig/network-scripts), but there's no sysconfig folder in ubuntu/debian. Using ifconfig makes the changes temporary right, or is it permanent?

It should be /etc/network/interfaces, unless they moved it recently. Maybe it's part of NetworkManager now?

The version of Ubuntu that you're using would be nice to know...

It's 10.10.

This is all I get in the config file:

root@htpc:~# cat /etc/network/interfaces 
auto lo
iface lo inet loopback

Figured it out. More involved than I figured, but it works.

also had to add "ifup eth0" in /etc/rc.local as it would not come online by default. I'm guessing networking service is not on by default and ubuntu does not have the chkconfig util and I was too lazy to do it the manual way.

That's the NetworkManager crap, it's nice for a laptop but gets in the way for servers, IMO. And there's a chkconfig package that you can install, but I never do because that's really just a RH-specific thing.
