First, accept() the incoming connection. The accepting process now has a handle to the listening socket, and the newly accepted socket. Fork and: In the child: Close the listening socket. Do stuff with the accepted socket. In the parent: Close the accepted socket. Resume the accept loop. The various socket resources will be reclaimed when …

You can bind to a port multiple times using the ReuseAddress socket option. UdpClient udpClient = new UdpClient(); udpClient.Client.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.ReuseAddress, true); You’ll need to set the same option on the UDP server socket as well.
You can get this information via Environment for the port and the host you can obtain by using InternetAddress. @Autowired Environment environment; // Port via annotation @Value(“${server.port}”) int aPort; …… public void somePlaceInTheCode() { // Port environment.getProperty(“server.port”); // Local address InetAddress.getLocalHost().getHostAddress(); InetAddress.getLocalHost().getHostName(); // Remote address InetAddress.getLoopbackAddress().getHostAddress(); InetAddress.getLoopbackAddress().getHostName(); }
