[LUAU] ubuntu with python can't see multicast traffic

[Brian Chee]

So does anyone know of some sort of magic config item for ubuntu that will
allow a python app to be able to receive mulitcast traffic? 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.
