[Twisted-Python] Multicast Server and Client Question

[Baillargeon, Sonny]

Hello,

I am new to twisted and python and most of experience is in ksh and
perl.  I am trying to write a multicast client and server application.
I am not sure if this is working since I can't find a way to write to a
multicast group.  This is what I have for the listener:

from twisted.internet.protocol import DatagramProtocol
from twisted.internet.udp import MulticastMixin
from twisted.internet import reactor

class EchoMulticast(DatagramProtocol):

        def datagramReceived(self, datagram, address):
                self.transport.write(datagram,address)

def main():
        reactor.listenMulticast(7774, EchoMulticast(), "224.7.7.74")
        reactor.run()

if __name__== '__main__':
        main()


Unfortunately, there is no connectMulticast class.  How would I write to
a Multicast group?  Would I do a join to a Multicast group and write UDP
packets?  The connectUDP does not allow me to write to a multicast
network and port.

Thanks,
Sonny
