Hello Xemuth,

Your server code accepts only a single connection and then exits. You need to loop. Smile

SocketServer example:

	for(;;) { <<----------
		TcpSocket s;
		if(s.Accept(server)) {
			String w = s.GetLine();
			Cout() << "Request: " << w << " from: " << s.GetPeerAddr() << '\n';
			if(w == "time")
				s.Put(AsString(GetSysTime()));
			else
				s.Put(AsString(3 * atoi(~w)));
			s.Put("\n");
		}
	}

It you need to handle multiple incoming connections at the same time, you either fork (expensive) or use an array of nonblocking sockets and/or MT, once accepting them, loop over them asynchronously until the connection is closed.
Best regards,
