NAME
rad - router advertisement daemon
SYNOPSIS
rad [-dnv] [-f file] [-s socket]
DESCRIPTION
rad is an IPv6 router advertisement daemon. It periodically sends IPv6
router advertisement messages with prefix and default router information.
Clients like slaacd(8) use these to configure IPv6 addresses on network
interfaces and set default routes. Additionally it listens for IPv6
router solicitation messages and responds with router advertisements.
To have rad enabled at boot time, use "rcctl enable rad", which sets
rad_flags=""
in rc.conf.local(8).
A running rad can be controlled with the ractl(8) utility.
The options are as follows:
-d Do not daemonize. If this option is specified, rad will run in
the foreground and log to stderr.
-f file
Specify an alternative configuration file.
-n Configtest mode. Only check the configuration file for validity.
-s socket
Use an alternate location for the default control socket.
-v Produce more verbose output.
FILES
/etc/rad.conf Default rad configuration file.
/var/run/rad.sock UNIX-domain socket used for communication with
ractl(8).
