Today I wanted to set up my Linux box so that it had a static ip address for shared resources like Samba.

The network card that I happen to be using for it was eth0. If you are using a different one then you may need to modify the code below to match the eth* that you are using.

Here are the steps that I took to accomplish this:

1. I edited the /etc/network/interfaces file with:

PLAIN TEXT
CODE:
  1. sudo nano /etc/network/interfaces

2. I added the following lines:

PLAIN TEXT
CODE:
  1. auto eth0
  2. iface etho inet static
  3. address 192.168.1.2
  4. netmask 255.255.255.0
  5. gateway 192.168.1.1

3. I restarted networking on the box and all was good.

sudo /etc/init.d/networking restart

Pay close attention to the netmask and the gateway. If these are different you will need to make adjustments as needed. I found these in my routers web gui.

My completed /etc/network/interfaces now looks like:

PLAIN TEXT
CODE:
  1. auto lo
  2. iface lo inet loopback
  3.  
  4. auto eth0
  5. iface etho inet static
  6. address 192.168.1.2
  7. netmask 255.255.255.0
  8. gateway 192.168.1.1
