Overview
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 232.43.211.234 or ff3e::4321:1234 respectively.
