This is a very basic server that processes the buffers one character at a time. In a real-world application, the buffers would be larger. More seriously, it processes one listener at a time. If the <code>currSock.receive()</code> blocks, the loop will not process other clients. This opens the door for a trivial denial-of-service attack. A realistic echo service must multiplex clients. |
