NAME
       radvd - router advertisement daemon for IPv6
SYNOPSIS
       radvd [ -hsvc ] [ -d debuglevel ] [ -C configfile ] [ -p pidfile ] [ -m
       logmethod ] [ -l logfile ] [ -n  nodaemon  ]  [  -f  facility  ]  [  -t
       chrootdir ] [ -u username ]
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  4861).   With  these
       advertisements hosts can automatically configure  their  addresses  and
       some other parameters. It also defines "Neighbor Discovery Optimization
       for IPv6 over Low-Power Wireless  Personal  Area  Networks  (6LoWPANs)"
       (RFC6775).   They  also  can  choose  a  default  router based on these
       advertisements.
       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.
       -c, --configtest
              Test configuration and do startup tests and then exit.
       -n, --nodaemon
              Prevent the daemonizing.
       -d debuglevel, --debug debuglevel
              With  this  option  you  turn  on  debugging  information.   The
              debugging  level  is  an  integer in the range from 1 to 5, 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 background 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
              /run/radvd/radvd.pid is used.
       -m method, --logmethod 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.
              stderr_syslog
                     Logs   only  the  high  messages  (of  at  least  LOG_ERR
                     priority) to standard error,  and  everything  to  syslog
                     (default method).
              syslog Logs to syslog.
       -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  on  Linux  radvd  requires  access  to   the   /proc
              filesystem,  so  it  is  more  challenging  to set up the chroot
              environment.
       -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
              recommended 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).
