How to make IP address permanent?

I have Fedora 9 installed on a PC. X is not working, so I cannot use
/usr/bin/system-config-network to configure the network interface. So, I
used the "setup" command, which allows you to configure networking.
However, this does not save the changes to the /etc/sysconfig/network*
files. Neither does ifconfig. Is there a "non-gui" tool which will
allow me to permanently configure eth0's IP address?


-Thanks

system-config-network should figure out that it doesn't have X and run
in an ncurses window. But, you can simply edit the
/etc/sysconfig/network-scripts/ifcfg-eth0 file directly if you don't
want to run it, or if it doesn't fall back to ncurses for some reason.

Yes, the ncurses version does run, I enter the network parameters, but it
does not change or save them (as root). Great.

How about using an editor?

There are numerous settings besides the IP address in the
/etc/sysconfig/networking config files. I have edited these files in the
past, I'm just having difficulty believing that after all these years, I
still have a need to do so.

No, it is not supposed to change them. After you run
system-config-network, it's your job to run /etc/init.d/network restart
to apply the changes. Depending on what else you have running this
might not be such a great idea, which is why it's left to you.

What is your evidence that it's not saving your changes? Did you look
in the file in /etc/sysconfig/ that I quoted above? If your changes are
in fact there, then just restart the network. If they're not there,
then you have some more research to do. What happens when you edit the
file by hand? Or if you move the file and have config-network recreate
it?
