ssmping − check if you can receive IPv4/IPv6 multicast data from an internet host
ssmping [ −46 ] [ −I interface ] [ −c count ] 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 232.43.211.234 or ff3e::4321:1234 respectively.
For ssmpingd there are no options. For ssmping the options are as follows.
−4 |
Force IPv4 |
|||
−6 |
Force IPv6 |
-I interface
Interface to join on
-c count
Stop after sending (and receiving) count requests (and replies)
asmping(1) a tool for checking whether can receive ASM.
dbeacon(1) a distributed beacon multicast implementation.

ssmping and ssmpingd were developed by Stig Venaas during the early days of the m6bone, the IPv6 multicast backbone.
