Setting a static IP on Fedora 20

Question

Network Manager won't let me do that, and the command-line tools I used back in the older versions of Fedora don't seem to exist any more.

Answer 1

Works fine on F20/KDE. When you edit the connection the tab for IPv4 has a Method drop down box where you select "manual" and enter the address you desire.

Answer 2

GUI
1) gnome-control-center network
2) nm-connection-editor

COMMAND LINE
4) nmcli (you can use the interactive method to configure the network)
5) ip (from the iproute command) but here I think you'll need to disable NM
6) manually edit /etc/sysconfig/network-scripts/ifcfg-XXXX followed by:
a) nmcli dev disconnect
b) nmcli con reload
d) nmcli con up
...so that NetworkManager is aware that a change was made on the config file.
