NAME
       ssmping - check if you can receive IPv4/IPv6 multicast data from	an in-
       ternet host

SYNOPSIS
       ssmping [ -46v ]	[ -I interface ] [ -c count ] [	-s size	] host

       ssmpingd

DESCRIPTION
       ssmping and ssmpingd are	network	level multicast	management tools  that
       can  be used to check whether one can receive multicast packets via SSM
       from a host.  The host target given to ssmping must  run	 the  ssmpingd
       daemon,	which  listens	on UDP port 4321 for IPv4 and IPv6 unicast re-
       quests.	When it	receives one, it responds to a well known  SSM	multi-
       cast  group  which  ssmping just	have joined.  Depending	on whether the
       request was made	with IPv4 or IPv6,  the	 group	is  232.43.211.234  or
       ff3e::4321:1234 respectively.

OPTIONS
       For ssmpingd there are no options.  For ssmping the options are as fol-
       lows.

       -4     Force IPv4

       -6     Force IPv6

       -v     Print client and server version information.

       -I interface
	      Interface	to join	on

       -c count
	      Stop after sending (and receiving) count requests	(and replies)

       -s size
	      Request replies to have a	size of	size bytes

       days of the m6bone, the IPv6 multicast backbone.
