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

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

       ssmpingd

DESCRIPTION
       asmping and ssmpingd are	network	level multicast	management tools  that
       can  be used to check whether one can receive multicast packets via ASM
       from a host.  The host target given to asmping 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 the  specified  multicast
       group  which asmping just have joined.  Note that one can not use arbi-
       trary groups. Independent of what group is specified, the last  quarter
       of  the address is forced to be 234 or ::4321:1234 for IPv4 or IPv6 re-
       spectively.

OPTIONS
       For ssmpingd there are no options.  For asmping 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

       ssmping(1) a tool for checking whether can receive SSM.

       dbeacon(1) a distributed	beacon multicast implementation.

BUGS
       Please  report  them  to	Stig Venaas <venaas@uninett.no>, the author of
       this tool.

       days of the m6bone, the IPv6 multicast backbone.
