ssmpingd
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.
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

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