For your information, by default the Ubuntu 14 sets the interface to use DHCP. And here’s how to set a static IP address on ubuntu 14.
To change static IP through terminal, you have to Edit this configuration -> /etc/network/interfaces. In this example use 192.168.1.? (? = your absen number + 10) as our server IP address.
Now go to the TERMINAL, write this command:
farihin@farihin-virtual-machine:~$ sudo su
[sudo] password for farihin:
