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

dbeacon(1) a distributed beacon multicast implementation.
BUGS
Please report them to Stig Venaas <venaas@uninett.no>, the author of this tool.
HISTORY
ssmping and ssmpingd were developed by Stig Venaas during the early days of the m6bone, the IPv6 multicast backbone.

mcfirst - check if you can receive IPv4/IPv6 multicast
SYNOPSIS
mcfirst [ -46vr ] [ -I interface ] [ -c count ] [ -t time ] [ source ] group port
DESCRIPTION
mcfirst can be used to check whether one can receive multicast packets from a host. The host may send any type of multicast packets, any
application, IPv4 or IPv6, ASM or SSM. mcfirst joins the specified (source) and group, and listens to the specified port. mcfirst will by
default exit when the first packet is received, and print how long it waited.
OPTIONS
The options are as follows.
-4 Force IPv4
-6 Force IPv6
-v Print version
-r Print rate information only
-I interface
Interface to join on
-c count
Stop after receiving count packets. Default is 1 unless time limit is specified
-t time
Exit after time seconds. Default is to exit after the first packet. If both count and time are specified, mcfirst will exit as soon
as one of them is satisfied.

Hello all,
I have the following question:
if you join a multicast group (with setsockopt() and IP_ADD_MEMBERSHIP) and specify INADDR_ANY as network interface to join on, the kernel is supposed to choose which interface to use (if there are multiple network interfaces, of course).
Does... (2 Replies)

On HP-UX, we want to exchange data via multicast, there happen to meet a problem: sometimes the receiver that has joined the group can not receive the multicast data, but the recvfrom call returned no error. We have reconfig the network and added the default the route, but still can not fixed it,... (0 Replies)
Hi, there
On HP-UX, I want to multicast packets on two different IP network repectively.
The two NIC are configured with two different IP. The routes are added with one default and one net for each IP . The multisender programs bind their own local IP, multireceiver programs add the... (0 Replies)
We have a solaris 9 box which is likely not communicating with the other host in the multicast group.

Is there a way to track down what process is sending to a certain port? I have some thing pounding the network with requests to a multicast IP that doesn't exist. I have shut down all comms related processes and yet it is still there. Need a way to track the port or IP back to the process. Thanks... (3 Replies)
I have two files like this:
#FILE 1
ABCD 4322 26485
JMTJ 5311 97248
XMPJ 4321 58978
#FILE 2
ABCD 4321 26485
JMTJ 5311 97248
XMPJ 4321 68978
What to do: Compare the two files and find those lines that doesn't match. And have a new file like this:
#FILE 3
"from file 1"
