I'll see in a bit when I get back to the ship....seems the shipboard folks are blocking access tho the worlds for anything other than email....so downloads of some libraries failed...the hassle is that they failed quietly.....so today I'm going to bring up my 4g router and bypass the ship internet connection.
thanks....

Using tcpdump I can see the IGMP joins and when I use tcpdump using this: tcpdump ip multicast and not broadcast I can see the igmp joins in wireshark and then after the briefest of pauses, the multicast starts up...I'm interested in 225.0.10.13 but this tcpdump syntax also brings up the other multicast from windows, etc... I've also started barking up the apparmor tree, and have gone as far as building a profile for it...but still not getting the multicast to the python app, whereas another machine (ubuntu 10.x as opposed to ubuntu 11.x on this machine) and the multicast data populates the python app just fine. /brian chee _______________________________________________ LUAU@lists.freesoftwarehawaii.org mailing list http://lists.freesoftwarehawaii.org/listinfo.cgi/luau-freesoftwarehawaii.org _______________________________________________ LUAU@lists.freesoftwarehawaii.org mailing list http://lists.freesoftwarehawaii.org/listinfo.cgi/luau-freesoftwarehawaii.org _______________________________________________ LUAU@lists.freesoftwarehawaii.org mailing list http://lists.freesoftwarehawaii.org/listinfo.cgi/luau-freesoftwarehawaii.org
