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