NAME

ifup - bring a network interface up

ifdown - take a network interface down  

SYNOPSIS

ifup [-sinv] [--interfaces=file] [--no-act] [--verbose] [-a|ifaces]

ifdown [-sinv] [--interfaces=file] [--no-act] [--verbose] [-a|ifaces]  

DESCRIPTION

The ifup and ifdown commands may be used to configure (or, respectively, deconfigure) network interfaces, based on descriptions of the interfaces entered into the file /etc/network/interfaces.  

OPTIONS

These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below.
-h, --help
Show summary of options.
-V, --version
Show copyright and version information.
-a, --all
Affect all interfaces marked auto.
-i file, --interfaces file
Read interface definitions from a different file.
-v, --verbose
Show commands being executed.
-n, --no-act
Don't actually execute the commands (this doesn't disable mappings, however)
--no-mappings
Don't run any mappings.
--force
Force de/configuration of interface.
 

NOTES

The ifup and ifdown programs don't actually know anything about configuring interfaces themselves but instead invoke lower-level utilities such as ifconfig and route to do the actual dirtywork. The main advantages to using ifup and ifdown instead of calling the lower-level utilities directy is the ability to keep all your interface specifications in a single (easily parsable) file, and to not have to deal with the various idiosyncracies of the lower-level commands.  

FILES

/etc/network/interfaces
Descriptions of all the network interfaces the system has.
/etc/network/ifstate
Current state of network interfaces.
