I am aware that many people prefer to disable NetworkManager, but I don't believe it will be going away and I decided to try to learn how to use it properly. I thought I would begin with something simple, like setting a static IP.
I updated /etc/sysconfig/network-scripts/ifcfg-eth0
to match the settings I want it to have, then saved the file. From what I have read, NetworkManager is supposed to update the settings immediately, but it does not. In fact, after both restarting NM and after a reboot, eth0 keeps using dhcp. I am using a minimal install of Fedora 18 and have installed dhcp, but not yet configured it. ifconfig is no longer part of a minimal install, apparently it is headed towards deprecation.
Below is my ifcfg-eth0 file.
