Tzury, You may consider using pymills to simplify writing your UDP server and just concentrating on the behavior of the system.
You can get a copy of the latest development branch by cloning it with Mercurial: hg clone http://hg.shortcircuit.net.au/pymills/ There is an example UDP Server in examples/net/ but I'll paste it here for your reference. Note, as stated before, UDP is a connectionless protocol (Datagram), concurrency doesn't apply. Also note, technically UDP doesn't guarantee reliability or the order of packets, however the reality is, it doesn't give you any feedback. You have to handle this yourself. Have fun, cheers James #!/usr/bin/env python # -*- coding: utf-8 -*- # vim: set sw=3 sts=3 ts=3 from pymills import event from pymills.event import * from pymills.net.sockets import UDPServer class EchoServer(UDPServer): @listener("connect") def onCONNECT(self, sock, host, port): print "New connection: %s:%d" % (host, port) @listener("disconnect") def onDISCONNECT(self, sock): print "Disconnection: %s" % sock @listener("read") def onREAD(self, sock, line): line = line.strip() print "%s: %s" % (sock, line) @listener("error") def onERROR(self, sock, msg): print "ERROR (%s): %s" % (sock, msg) def main(): server = EchoServer(1234) event.manager += server while True: try: manager.flush() server.poll() except KeyboardInterrupt: break if __name__ == "__main__": main() On Thu, Sep 11, 2008 at 5:33 AM, Tzury Bar Yochay <[EMAIL PROTECTED]> wrote: >> Transmitting large binary data over UDP?
