You can use vim.tiny

 

Open the following file:

sudo vim.tiny /etc/network/interfaces

 

You want it to look similar to this (changing the IP addresses to match your network):

 

auto eth0

iface eth0 inet static

address 192.168.1.100

netmask 255.255.255.0

network 192.168.1.0

broadcast 192.168.1.255

gateway 192.168.1.1

 

When do, save the file by :wq and restart networking or reboot the appliance.
