How to set a static IP in Ubuntu from the shell
One of the first things I do for my desktops is set them with a static IP. Below is how I go about it.
First uninstall Network Manager. This will just simply get in the way.
Edit as root:
/etc/network/interfaces
and adjust it to your needs (in this example setup I will use the IP address 192.168.0.100):
# This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo iface lo inet loopback # This is a list of hotpluggable network interfaces. # They will be activated automatically by the hotplug subsystem. mapping hotplug script grep map eth0 # The primary network interface auto eth0 iface eth0 inet static address 192.168.0.100 netmask 255.255.255.0 network 192.168.0.0 broadcast 192.168.0.255 gateway 192.168.0.1
