I need to write a server which is able to identify client by
My machine is listening to “0.0.0.0”, any IP addrs configured to it.
Take for instance, the machine is configured with “192.168.1.10,
172.16.0.10”, also listening to “0.0.0.0”, allow listening to Broadcast
queries, which is also important to my application
Hence, if one of the clients send a UDP packet to it, the server program
would check the destination address of the client request and reply the
client with different “answers”.
I’ve not been lucky enough to google how to get the destination address
of a incoming packet.
Hope someone here could shed some light. Thanks
