asmping(1) General Commands Manual asmping(1)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.
BUGS
Please report them to Stig Venaas <venaas@uninett.no>, the author of this tool.
HISTORY
asmping and ssmpingd were developed by Stig Venaas during the early days of the m6bone, the IPv6 multicast backbone.

mcsender - Multicast test tool to send multicast test packets
SYNOPSIS
mcsender [-t<ttl>] [-i<interface>] ip:port
DESCRIPTION
mcsender sends multicast packets to the specified IPv4 or IPv6 multicast address and port. The packets sent contain the string "this is the
test message from mclab/mcsender
".
OPTIONS
-t<ttl>
Set the TTL (or hop limit for IPv6) to the specified value.
-i<interface>
Specify the interface to use for outgoing multicast datagrams.
EXAMPLES
To send datagrams to IPv4 multicast address 239.1.1.1 and port 12345 with a TTL of 3:
$ mcsender -t3 239.1.1.1:12345
To send datagrams to IPv4 multicast address 239.1.1.1 and port 12345 with a TTL of 3 out of interface eth1:
$ mcsender -ieth1 -t3 239.1.1.1:12345
To send datagrams to IPv6 multicast address ff15::1 and port 12345 with a hop limit of 3:
$ mcsender -t3 ff15::1:12345
To send datagrams to IPv6 multicast address ff15::1 and port 12345 with a hop limit of 3 out of interface eth1:
$ mcsender -ieth1 -t3 ff15::1:12345

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

#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:
