NAME
asmping - check if you can receive IPv4/IPv6 multicast data from an
internet host
SYNOPSIS
asmping [ -46v ] [ -I interface ] [ -c count ] [ -s size ] group host
ssmpingd
DESCRIPTION
asmping and ssmpingd are network level multicast management tools that
can be used to check whether one can receive multicast packets via ASM
from a host. The host target given to asmping must run the ssmpingd
daemon, which listens on UDP port 4321 for IPv4 and IPv6 unicast
requests. When it receives one, it responds to the specified multicast
group which asmping just have joined. Note that one can not use
arbitrary groups. Independent of what group is specified, the last
quarter of the address is forced to be 234 or ::4321:1234 for IPv4 or
IPv6 respectively.
OPTIONS
For ssmpingd there are no options. For asmping 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
SEE ALSO
ssmping(1) a tool for checking whether can receive SSM.
dbeacon(1) a distributed beacon multicast implementation.
