Python Forum

Good morning, folks.

I'm looking to use Python to do some work with IP Multicast under version 3.7.

However, the wrinkle in the system is that the particular stream I need to join is a source-specific stream, with the socket option only existing for IGMPv2 with IP_ADD_MEMBERSHIP. In my online searches, the only other references I have been able to find are in C, which reference IP_ADD_SOURCE_MEMBERSHIP.

socketIn.setsockopt(socket.IPPROTO_IP, socket.SO_REUSEADDR, 1)
socketIn.setsockopt(socket.IPPROTO_IP, socket.IP_ADD_MEMBERSHIP,
                    (socket.inet_aton(groupAddr)+socket.inet_aton(myAddr)))

I'd rather not spoof out my own IGMPv3 packets, or make an SSM map on my network, but that looks like it may be necessary for me to join the stream I need.

Is it possible that a future version of Python will support this and its associated socket options?

Thanks in advance!
