This process uses the command line to set a static IP address on Ubuntu Server 14.04.
Note: If you do this process from an SSH session, you will lose connection when you enter the final command. But if you did everything correct, you simply need to establish a new session using the static IP address you assigned.
sudo nano /etc/network/interfaces
This is what the default file will look like:
# This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet dhcp
This similar to what should look like for a static IP. Of course, use addresses relevant to your network:
# The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet static address 10.5.1.33 netmask 255.0.0.0 gateway 10.5.1.254 dns-nameservers 10.5.1.2 126.96.36.199 188.8.131.52
Lastly you need to reload networking:
sudo ifdown eth0 && sudo ifup eth0
