Hi Ian,
What about using a media application like vlc (videolan) and joining a multicast group? I think you might be able to run it in command line mode, if you don't have an X server listening. This'll trigger your IGMP membership reports and respond to group queries.
If you just want to bang out some IGMP packets, the Nemesis packet
generation tool (apt-get install) has an IGMP function:
$ nemesis igmp help
IGMP Packet Injection -=- The NEMESIS Project Version 1.4
IGMP usage:
igmp [-v (verbose)] [options]
IGMP options:
-p <IGMP type>
-c
-i <IGMP group IP address>
-P <Payload file>
IP options:
-S <Source IP address>
-D <Destination IP address>
-I <IP ID>
-T <IP TTL>
-t <IP TOS>
-F <IP fragmentation options>
-F[D],[M],[R],[offset]
-O <IP options file>
Data Link Options:
-d <Ethernet device name>
-H <Source MAC address>
-M <Destination MAC address>
Otherwise, if you're in the market for flexible packet generation, Scapy
is an excellent python framework. It doesn't appear to have any IGMP
specific support yet, but it's pretty easy to extend. In fact, a quick
google suggests a few people have already written an IGMP class for it.
