The mld6query command relies on KAME behaviour which allows the ipv6mr_multiaddr member of the request object in a IPV6_JOIN_GROUP setsockopt() call to be INADDR6_ANY. The FreeBSD stack doesn't allow this, so mld6query has been non-functional. Also, add a -g option which sends a General Query (query INADDR6_ANY) Reviewed by: sbruno, mmacy Sponsored by: Limelight Networks Differential Revision: https://reviews.freebsd.org/D15384

.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility sends an IPv6 multicast listener discovery (MLD) query packet toward
|
|
the specified multicast address,
|
|
.Ar maddr ,
|
|
toward interface
|
|
.Ar intface .
|
|
If you omit
|
|
.Ar maddr ,
|
|
linklocal all nodes multicast address(ff02::1) is used.
|
|
.Pp
|
|
After sending a query,
|
|
.Nm
|
|
waits for replies for at most 10 seconds.
|
|
If a reply is returned,
|
|
.Nm
|
|
prints it with its type and then waits for another reply.
|
|
.Pp
|
|
This program is provided only for debugging.
|
|
It is not necessary for normal use.
|
|
.Pp
|
|
With
|
|
.Fl g ,
|
|
.Nm
|
|
will transmit a General Query instead of the default Multicast-Address-Specific Query.
|
|
With
|
|
.Fl d ,
|
|
.Nm
|
|
will transmit MLD done packet instead of MLD query packet.
|
|
With
|
|
.Fl r ,
|
|
similarly, MLD report packet will be transmitted.
|
|
.Fl dr
|
|
options are for debugging purposes only.
|
|

|
|
.Sh EXIT STATUS
|
|
The program exits with 0 on success, non-zero on failures.

.Sh HISTORY
|
|
The

.Nm
|
|
utility first appeared in WIDE/KAME IPv6 protocol stack kit.
|
|
.Sh BUGS
|
|
The
|
|
.Nm
|
|
utility does not take care of multicast addresses which have non link-local
|
|
scope.
