In Debian:

02 – Edit interface settings

Edit the interfaces file:

# nano /etc/network/interfaces

Change “dhcp” to “static” configuration and fill the follow areas with your network information.


Restart network service:

# /etc/init.d/networking restart

03 – Test

To test if everything is working ok, run:

# ifconfig

The result need to be something like this:


And that’s it. Any question, just leave a comment below.
