2 # /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)
5 # !!!NOTE!!! THIS IS AN ALPHA RELEASE! DO NOT RELY ON IT!
7 # Consider this the first draft of what I think the proper way to
8 # configure interfaces is. It makes use of programs like ifconfig(8)
9 # and dhcpcd(8), and can be called from /etc/init.d/networking,
10 # /etc/pcmcia/network or the command line. It can configure and
11 # deconfigure interfaces. In controlled environments it even works.
12 # It's *very* subject to change, however. Some of the compulsory
13 # options will become optional. Some of the optional ones might
14 # become compulsory. Syntax might change. Features might disappear.
15 # Bugs might disappear. The examples below are reasonably likely
16 # to remain more or less correct. Maybe.
20 # A "#" character in the very first column makes the rest of the line
21 # be ignored. Blank lines are ignored. Lines may be indented freely.
22 # A "\" character at the very end of the line indicates the next line
23 # should be treated as a continuation of the current one.
25 # The "noauto", "up", and "down" options are valid for all interfaces.
26 # "up" and "down" may be specified multiple times, all other options
27 # may only be specified once.
