NAME

       radvd - router advertisement daemon for IPv6

SYNOPSIS

       radvd  [  -vh ] [ -d debuglevel ] [ -C configfile ] [ -p pidfile ] [ -m method ] [ -l logfile ] [ -f facility ] [ -t chrootdir ] [ -u user-
       name ]

DESCRIPTION

       radvd is the router advertisement daemon for IPv6. It listens to router solicitations and  sends  router  advertisements  as  described	in
       "Neighbor  Discovery  for IP Version 6 (IPv6)" (RFC 2461).  With these advertisements hosts can automatically configure their addresses and
       some other parameters. They also can choose a default router based on these advertisements.

       Note that if debugging is not enabled, radvd will not start if IPv6  forwarding	is  disabled.	IPv6  forwarding  can  be  controlled  via
       sysctl(8), net.ipv6.conf.all.forwarding on Linux or net.inet6.ip6.forwarding on BSD.

       Similarly, the configuration file must not be writable by others, and if non-root operation is requested, not even by self/own group.

OPTIONS

       For every one character option there is also a long option, which is listed right next to the "short" option name:

       -v, --version
	      Displays the version of radvd and then aborts.

       -h, --help
	      Displays a short usage description and then aborts.

       -d debuglevel, --debug debuglevel
	      With  this option you turn on debugging information. The debugging level is an integer in the range from 1 to 4, from  quiet to very
	      verbose. A debugging level of 0 completely turns off debugging. If a debugging level greater than 0 is  used,  radvd  doesn't  back-
	      ground itself on start. The default debugging level is 0.

       -C configfile, --config configfile
	      Specifies an alternate config file. Normally the compiled in default /etc/radvd.conf is used.

       -p pidfile, --pidfile pidfile
	      Specifies an alternate pidfile. Normally the compiled in default /var/run/radvd/radvd.pid is used.

       -m method, --method method
	      Specifies the logging method to use. Possibly values are:

	      none   Completely disables any logging.

	      logfile
		     Logs  to  the logfile which is specified by the -l option. If no logfile is specified on the command line, then a compiled in
		     default is used (see next option).

	      stderr Logs to standard error.

	      syslog Logs to syslog (default method).

       -l logfile, --logfile logfile
	      Specifies the logfile to use when using the logging method logfile.  The default logfile is /var/log/radvd.log.

       -f facility, --facility facility
	      Specifies the facility (as an integer) when using syslog logging. Default is LOG_DAEMON.

       -t chrootdir, --chrootdir chrootdir
	      If specified, switches to chrootdir before doing anything else.  This directory and its  subdirectories  must  have  been  populated
	      first.  For security reasons, -u must always be used when using chrootdir.

	      Note that this option will not currently work under Linux because radvd requires access to the /proc filesystem.

       -u username, --username username
	      If  specified,  drops root privileges and changes user ID to username and group ID to the primary group of username.  This is recom-
	      mended for security reasons.  You might also need  to  use  -p  to  point  to  a	file  in  a  username  -writable  directory  (e.g.
	      /var/run/radvd/radvd.pid).
