Convert debain/ubuntu to static IP

My Ubuntu Mini-ITX server was by default being assined an IP through DHCP from the router. If my router could assign IP based on the MAC address I would not have to assign a STATIC IP on the machine itself but could control it from a central location. Since I dont have this most of my machine have a static IP assigned. For Debain and Ubuntu systems this is quite easy.
Following instructions are for eth0 (the first real network socket)

$sudo vim /etc/network/interfaces

This text should already be present
auto lo
iface lo inet loopback

if these lines are present delete/comment out (#at the beginning of the line is a commet)
auto eth0
iface eth0 inet dhcp

Add the following (replace the x's with the assigned ip)
#### Manually Added Below Morgy ####
auto eth0
iface eth0 inet static
address 192.168.1.x
gateway 192.168.1.x

Now restart networking
$ sudo /etc/init.d/networking restart
