NAME
ssmping - check if you can receive IPv4/IPv6 multicast data from an
internet host
SYNOPSIS
ssmping [ -46v ] [ -I interface ] [ -c count ] [ -s size ] host
ssmpingd
DESCRIPTION
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.
OPTIONS
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
