28 CHAPTER 2 N UDP First, doing a connect() on a UDP socket does not send any information across the network or do anything to warn the server that packets might be coming. It simply writes the address into the operating system’s memory for use when you later call send() and recv(). Second, please remember that doing a connect()—or even filtering out unwanted packets yourself using the return address—is not a form of security! If there is someone on the network who is really malicious, it is usually easy enough for their computer to forge packets with the server’s return address so that their faked replies will make it past your address filter just fine.
I glanced over the list and made the gamble that you, gentle reader, are not running SAP BusinessObjects Polestar on the laptop or desktop or server where you are running my Python scripts. If you are, then try giving the server a –p option to select a different port number. Note that the Python program can always use a socket’s getsockname() method to retrieve a tuple that contains the current IP address and port to which the socket is bound. Once the socket has been bound successfully, the server is ready to start receiving requests!
This is because of the second, less-obvious effect of using connect() to configure a UDP socket’s preferred destination: once you have run connect(), the operating system will discard any incoming packets to your port whose return address does not match the address to which you have connected. There are, then, two ways to write UDP clients that are careful about the return addresses of the packets arriving back. u You can use sendto() and direct each outgoing packet to a specific destination, then use recvfrom() to receive the replies and carefully check each return address against the list of servers to which you have made outstanding requests.
