######################################################################
# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)
#
# A "#" character in the very first column makes the rest of the line
# be ignored. Blank lines are ignored. Lines may be indented freely.
# A "\" character at the very end of the line indicates the next line
# should be treated as a continuation of the current one.
#
# The "pre-up", "up", "down" and "post-down" options are valid for all
# interfaces, and may be specified multiple times. All other options
# may only be specified once.
#
# See the interfaces(5) manpage for information on what options are
# available.
######################################################################
# We always want the loopback interface.
#
# auto lo
# iface lo inet loopback
# An example ethernet card setup: (broadcast and gateway are optional)
#
# auto eth0
# iface eth0 inet static
# address 192.168.0.42
# network 192.168.0.0
# netmask 255.255.255.0
# broadcast 192.168.0.255
# gateway 192.168.0.1
# A more complicated ethernet setup, with a less common netmask, and a downright
# weird broadcast address: (the "up" lines are executed verbatim when the
# interface is brought up, the "down" lines when it's brought down)
#
# auto eth0
# iface eth0 inet static
# address 192.168.1.42
# network 192.168.1.0
# netmask 255.255.255.128
# broadcast 192.168.1.0
# up route add -net 192.168.1.128 netmask 255.255.255.128 gw 192.168.1.2
# up route add default gw 192.168.1.200
# down route del default gw 192.168.1.200
# down route del -net 192.168.1.128 netmask 255.255.255.128 gw 192.168.1.2
# A more complicated ethernet setup with a single ethernet card with
# two interfaces.
# Note: This happens to work since ifconfig handles it that way, not because
# ifup/down handles the ':' any differently.
# Warning: There is a known bug if you do this, since the state will not
# be properly defined if you try to 'ifdown eth0' when both interfaces
# are up. The ifconfig program will not remove eth0 but it will be
# removed from the interfaces state so you will see it up until you execute:
# 'ifdown eth0:1 ; ifup eth0; ifdown eth0'
# BTW, this is "bug" #193679 (it's not really a bug, it's more of a
# limitation)
#
# auto eth0 eth0:1
# iface eth0 inet static
# address 192.168.0.100
# network 192.168.0.0
# netmask 255.255.255.0
# broadcast 192.168.0.255
# gateway 192.168.0.1
# iface eth0:1 inet static
# address 192.168.0.200
# network 192.168.0.0
# netmask 255.255.255.0
# "pre-up" and "post-down" commands are also available. In addition, the
# exit status of these commands are checked, and if any fail, configuration
# (or deconfiguration) is aborted. So:
#
# auto eth0
# iface eth0 inet dhcp
# pre-up [ -f /etc/network/local-network-ok ]
#
# will allow you to only have eth0 brought up when the file
# /etc/network/local-network-ok exists.
# Two ethernet interfaces, one connected to a trusted LAN, the other to
# the untrusted Internet. If their MAC addresses get swapped (because an
# updated kernel uses a different order when probing for network cards,
# say), then they don't get brought up at all.
