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. /Chris ----- Original Message ---- From: Ian Batterbee <ian.batterbee(a)aut.ac.nz> To: nznog(a)list.waikato.ac.nz Sent: Tuesday, January 16, 2007 10:45:30 PM Subject: [nznog] IGMP test tools Hi all, I'm looking for some linux test tools that I can run that will send IGMP join commands and that will respond to IGMP queries (to keep the group alive), that I can use to prove or disprove a sparse mode pim configuration. There's such a blatent lack of matches for anything like this on google that I wonder if I'm overlooking some basic utility that is already included with most distros or is built into the kernel, but I can't come up with anything on that front either. Using a Cisco router or switch as a multicast group member is a possibility, but I'd rather use linux hosts if I can do so. _______________________________________________ NZNOG mailing list NZNOG(a)list.waikato.ac.nz http://list.waikato.ac.nz/mailman/listinfo/nznog
