Configuring a static IP address

Edit the file /etc/network/interfaces to contain the following entries:

# The primary network interface
auto eth0
iface eth0 inet static
  address 192.168.0.20
  netmask 255.255.255.0
  broadcast 192.168.0.255
  gateway 192.168.0.1

Reconfigure the network interfaces with the following command:

user@ubuntu:~$ sudo /etc/init.d/networking restart
