Because the operating system can see whether one of its own ports is opened without sending a packet across the network, it immediately replies that a connection to that port is impossible! But beware that this ability for UDP to return “Connection refused” is a superpower of the loopback that you will never see on the real network. There the packet must simply be sent with no indication of whether there is a destination port to receive it. Try running the client again on the same machine, but this time use the external IP address of the box.
The client code is also shown in Listing 2-1. (I hope, by the way, that it is not confusing that this example—like some of the others in the book—combines the server and client code into a single listing, selected by command-line arguments. 0', 39288) replied 'Your data was 46 bytes long' Over in the server’s command window, you should see it reporting each connection that it serves. 065836' Although the client code is slightly simpler than that of the server—there are only three lines of networking code—it introduces two new concepts.
First, the TCP connect() call—as I discussed a moment ago—is not the innocuous bit of local socket configuration that it is in the case of UDP, where it merely sets a default remote address to be used with any subsequent send() or recv() calls. Here, connect() is a real live network operation that kicks off the three-way handshake between the client and server machine so that they are ready to communicate. This means that connect() can fail, as you can verify quite easily by executing the client when the server is not running.
