- Improve interface list handling. The rtadvd(8) now supports dynamically-
added/removed interfaces in a more consistent manner and reloading the configuration file. - Implement burst unsolicited RA sending into the internal RA timer framework when AdvSendAdvertisements and/or configuration entries are changed as described in RFC 4861 6.2.4. This fixes issues that make termination of the rtadvd(8) daemon take very long time. An interface now has three internal states, UNCONFIGURED, TRANSITIVE, or CONFIGURED, and the burst unsolicited sending happens in TRANSITIVE. See rtadvd.h for the details. - rtadvd(8) now accepts non-existent interfaces as well in the command line. - Add control socket support and rtadvctl(8) utility to show the RA information in rtadvd(8). Dumping by SIGUSR1 has been removed in favor of it.

.Sh NAME
|
||||
.Nm rtadvctl
|
||||
.Nd control program for
|
||||
.Xr rtadvd 8 daemon
|
||||
.Sh SYNOPSIS
|
||||
.Nm
|
||||
.Op Fl v
|
||||
.Ar subcommand
|
||||
.Op Ar interface ...
|
||||
.Sh DESCRIPTION
|
||||
.Nm
|
||||
is a utility that communicates with
|
||||
.Xr rtadvd 8
|
||||
daemon and displays information about Router Advertisement messages being
|
||||
sent on each interface.
|
||||
.Pp
|
||||
This utility provides several options and subcommands.
|
||||
The options are as follows:
|
||||
.Bl -tag -width indent
|
||||
.\"
|
||||
.It Fl v
|
||||
Increase verbosity level.
|
||||
When specified once, the
|
||||
.Nm
|
||||
utility shows additional information about prefixes, RDNSS, and DNSSL
|
||||
options.
|
||||
When given twice, it additionally shows information about
|
||||
inactive interfaces and some statistics.
|
||||
.El
|
||||
.Pp
|
||||
The subcommands are as follows:
|
||||
.Bl -tag -width indent
|
||||
.\"
|
||||
.It reload Op interfaces...
|
||||
Specifies to reload the configuration file. If one or more
|
||||
.Ar interface
|
||||
is specified, configuration entries for the interfaces will be reloaded
|
||||
selectively.
|
||||
.It enable interfaces...
|
||||
Specifies to mark the interface as enable and to try to reload the
|
||||
configuration entry.
|
||||
This subcommand is useful for dynamically-added interfaces.
|
||||
.Pp
|
||||
The
|
||||
.Xr rtadvd 8
|
||||
daemon marks an interface as enable if the interface exists and the
|
||||
configuration file has a valid entry for that when it is invoked.
|
||||
.It disable interfaces...
|
||||
Specifies to mark the interface as disable.
|
||||
.It shutdown
|
||||
Makes the
|
||||
.Xr rtadvd 8
|
||||
daemon shut down.
|
||||
Note that the
|
||||
.Xr rtadvd 8
|
||||
daemon will send several RAs with zero lifetime to invalidate the old
|
||||
information on each interface.
|
||||
It will take at most nine seconds.
|
||||
.It show Op interfaces...
|
||||
Displays information on Router Advertisement messages being sent
|
||||
on each interface.

||||
