How to setup /etc/network/interfaces file in ubuntu

How to setup interfaces file in ubuntu?

Open interfaces file with text editor (I use vim)

sudo vim /etc/network/interfaces

Now you have two ways to setup your interface

1) setup int to DHCP - in this case interface is eth0:

auto eth0
iface eth0 inet dhcp

2) Setup interface with static IP address:
 
iface eth0 inet static
address 192.168.1.5
netmask 255.255.255.0
gateway 192.168.1.254
