IFSTATED(8) BSD System Manager's Manual IFSTATED(8)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
