Have you opened the /etc/network/interfaces file with root permissions?

you can do $sudo nano /etc/network/interfaces

Add code similar to following. ( change entries where appropriate, make 
sure about eth0 by issuing command $ ifconfig  )

auto eth0
iface eth0 inet static
address 10.2.2.100
netmask 255.255.255.0
gateway 10.0.0.1

You can exit by doing Ctrl-X and then y.
