man ssmping (Commandes) - check if you can receive IPv4/IPv6 multicast data from an internet host
NAME
ssmping - check if you can receive IPv4/IPv6 multicast data from an internet host
SYNOPSIS
ssmping [ -46 ] [ -I interface ] [ -c count ] 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
- -I interface
- Interface to join on
- -c count
- Stop after sending (and receiving) count requests (and replies)
