Port reusing problem with sockets.

Question

I have the following simple client/server classes. I can't get the client to reuse ports. When creating 5 sockets (not simultaneous) to the same endpoint 5 new local ports are opened and when closed set to TIME_WAIT.
The code:
Client:
import java.io.IOException;
import java.net.InetSocketAddress;
import java.net.Socket;
public class SocketClient {
   public static void main(String[] args) {
      new SocketClient();
   public SocketClient() {
      for (int i = 0; i < 5; i++) { 
         Socket socket = new Socket();      
         try {
            socket.connect(new InetSocketAddress("tonic", SocketConstants.port));
            socket.setReuseAddress(true);
            socket.getOutputStream().write(3);
            try {
               Thread.sleep(100);
            } catch (Exception ex) {}
            System.out.println("socket.getInputStream().read() = " + socket.getInputStream().read());
         } catch (IOException ex) {
            ex.printStackTrace();
         } finally {
            try {
               socket.close();
            } catch (IOException ex1) {
               //.. do nothing
}Server:
import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;
public class SocketServer {
   public static void main(String[] args) {
      new SocketServer();
   public SocketServer() {
      ServerSocket servSocket = null;
      try {
         servSocket = new ServerSocket(SocketConstants.port);
         servSocket.setReuseAddress(true);
      } catch (IOException ex) {
         ex.printStackTrace();
      while (true) {
         Socket socket = null;
         try {
            socket = servSocket.accept();
            System.out.println("socket.getRemoteSocketAddress() = " + socket.getRemoteSocketAddress());
            System.out.println("socket.getInputStream().read() = " + socket.getInputStream().read());
            socket.getOutputStream().write(4);
            System.out.println("socket.getInputStream().read() = " + socket.getInputStream().read());
            try {
               Thread.sleep(400);
            } catch (Exception ex) {
               ex.printStackTrace();
         } catch (Exception ex) {
            ex.printStackTrace();
         } finally {
            if (socket != null) {
               try {
                  socket.close();
               } catch (IOException ex) {
                  ex.printStackTrace();
}Do I need to use socket.bind(..) or how can I get my client to reuse ports in TIME_WAIT state?

Answer 1

The TIME_WAIT state is there for a reason; it's your friend and it's there to help you :-)

Why do you think TIME_WAIT is a problem? Try not to shoot yourself in the foot; don't use setReuseAddress(true). Read the FAQ entry.
