NAME

     ifstated - Interface State daemon


SYNOPSIS

     ifstated [-dhinv] [-D macro=value] [-f file]


DESCRIPTION

     The ifstated daemon runs commands in response to network state changes,
     which it determines by monitoring interface link state or running
     external 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.

     -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
