RADVDUMP(8)RADVDUMP(8)NAME
radvdump - dump router advertisements
SYNOPSIS
radvdump [ -vhfe ] [ -d debuglevel ]
DESCRIPTION
radvdump prints out the contents of incoming router advertisements sent by radvd or some other software implementing (parts of) "Neighbor
Discovery for IP Version 6 (IPv6)" (RFC 2461).
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 radvdump and then aborts.
-h, --help
Displays a short usage description and then aborts.
-f, --file-format
Output received router advertisements in the format of the radvd configuration file.
-e, --exclude-defaults
Exclude default valued options from configuration file format. This option is ignored if option -f is not set.
-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.
The default debugging level is 0.
FILES
/usr/sbin/radvdump

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).
