/etc/network/interfaces:
The loopback network interface
auto lo
iface lo inet loopback
# This is a list of hotpluggable network interfaces.
# They will be activated automatically by the hotplug subsystem.
mapping hotplug
script grep
map eth0
map eth1
# The primary network interface
auto eth0
iface eth0 inet static
netmask 255.255.255.0
network 192.168.0.0
broadcast 192.168.0.255
iface eth1 inet static
