NAME
     ifstated — Interface State daemon

SYNOPSIS
     ifstated [-dhinv] [-D macro=value] [-f file] [-p pidfile]

DESCRIPTION
     The ifstated daemon runs commands in response to network state changes,
     which it determines by monitoring interface link state or running exter‐
     nal tests.	 For example, it can be used with carp(4) to change running
     services or to ensure that carp(4) interfaces stay in sync, or with pf(4)
     to test server or link availability and modify translation or routing
     rules.  The options are as follows:

     -D macro=value
	     Define macro to be set to value on the command line.  Overrides
	     the definition of macro in the configuration file.

     -d	     Do not daemonize and log to stdout.

     -f file
	     Specify an alternate location, file, for the configuration file.

     -p pidfile
	     Specify the location, pidfile, for the PID file.

     -h	     Print help message.

     -i	     Ignore initial interface states.

     -n	     Config test mode.	Check config validity, then exit.

     -v	     Verbose mode.  Use twice to further increase verbosity.

     Upon receiving SIGHUP, ifstated reloads the configuration file.

FILES
     /usr/local/etc/ifstated.conf  ifstated configuration file.

SEE ALSO
     carp(4), pf(4), ifstated.conf(5)

HISTORY
     The ifstated program first appeared in OpenBSD 3.8.
