Easy enough? By default, Ubuntu Server is configured with DHCP enabled but we need a static IP. The following tutorial will show you just how to do that!
Let’s open the interfaces configuration file.
sudo nano /etc/network/interfaces
It should look like the following.
auto eth0 iface eth0 inet dhcp
DHCP is currently set but we need a static IP. The following configuration will show what needs to be changed and add.
auto eth0 face eth0 inet static address 192.168.1.4 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255 gateway 192.168.1.1 dns-nameserver 192.168.1.2 192.168.1.1
In previous version of Ubuntu you needed to edit the /etc/resolv.conf and add a line. This is no longer the case.
I hope this tutorial helped!
