Right? I believe the socket receives all packets destined to that port, since the address hasn't been specified. That means the multicast messages AND the unicast messages. > In the second case socket receives unicast packets sent to the socket's > address+port AND all multicast messages sent to addresses of it's groups > (and received on corresponding interfaces) and the socket's port. Right? I believe here we would only receive the messages for the unicast address, as that is the one we have bound. > QUESTION: What messages should the socket receive in the third and > fourth cases? Case 3: The messages for that multicast group we've bound. Case 4: Nothing. I just woke up, so forgive me my mistakes :-) -- | [EMAIL PROTECTED] home: +358-50-3265194 | IRC naturae alienum est!
