I don't think this is possible.
Not to keep the client socket waiting for "nothing", that's totally possible, of course. If you are learning network programming, you may know a few about TCP/IP protocol stack.
If your client/server application communicate using UDP as transport protocol, excuse me then, it's possible. But if your application communicates using TCP as transport protocol, you're doing nothing keeping the client waiting for data that isn't going to arrive.
TCP uses sequence and acknowledgement numbers, on a server "crash" the application will need to be restarted. at this point, the server will start NEW connections, and forget about the previous ones.
The client application will be sending ack's or data to a connection that is no longer available, and the server will ignore the client. so, you are using UDP, right?
