How to set an IP address in Debian for an interface (or more) using the CLI/Terminal

Run the following in the CLI to add the IP

Temporary fix

ifconfig eth0 192.168.0.20 netmask 255.255.255.0 up
route add default gw 192.168.0.1
echo "nameserver 8.8.8.8" > /etc/resolv.conf

Run the following in a CLI to get the IP address

ip addr

For a permanent fix

nano /etc/network/interfaces

Change

iface eth0 inet dhcp

iface eth0 inet static
 address 192.168.0.20
 netmask 255.255.255.0
 network 192.168.0.0
 broadcast 192.168.0.255
 gateway 192.168.0.1

reset the interface

ifdown eth0
ifup eth0

To add an additional interface

iface eth1 inet static
 address 10.20.0.20
 netmask 255.255.255.0
 network 10.20.0.0
 broadcast 10.20.0.255

Note: gateway is removed as we only want to use the 192.168.0.1 default gateway

On boot

Need to add the interface to the auto config

auto lo eth0 eth1
