ssmping - check if you can receive IPv4/IPv6 multicast data from an internet host
ssmping [ -46v ] [ -I interface ] [ -c count ] [ -s size ] host ssmpingd
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 requests. When it receives one, it responds to a well known SSM multicast group which ssmping just have joined. Depending on whether the request was made with IPv4 or IPv6, the group is 184.108.40.206 or ff3e::4321:1234 respectively.
For ssmpingd there are no options. For ssmping the options are as follows. -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
