Set static IP

These settings are lost on reboot. This is just for a temporary config.

# ip route add default via 192.168.0.1
# ifconfig eth0 192.168.0.2 netmask 255.255.255.0

Virtual Interfaces

Add virtual interfaces is trivial in Linux. Just add a number to a real interface (in this example, eth0). So here we configure eth0:1:

# ifconfig eth0:1 192.168.0.3 netmask 255.255.255.0

Delete an interface

Use the 'down' command:

# ifconfig eth0:1 down
