Edit:
Also, if you are doing this you then need to invoke the object since the ServerSocket is a part of the class members and not a part of the main. At least I think so, let me double check.

Edit:
Yep, you need to invoke it then. You also need to override the constructor to add a checked exception for the IOException since it won't handle it otherwise.

I'#m using

import java.io.*;
import java.net.*;

public class PortListen {
    


    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
          try {

                    ServerSocket myServerSocket = new ServerSocket(43594);
                    
                    System.out.println("Server is waiting for an incoming connection on host-" + InetAddress.getLocalHost().getCanonicalHostName() + " port-" + myServerSocket.getLocalPort());
                    System.out.println("");

                        while (true) {

                            Socket skt = myServerSocket.accept();

                            BufferedReader myInput = new BufferedReader(new InputStreamReader(skt.getInputStream()));

                            String buf = myInput.readLine();

                            if (buf != null) {

                                    System.out.println("Server read: [" + buf + "]");
                                System.out.println("");

                            }

                        }

                } catch (IOException e) {

                        e.printStackTrace();
                        System.out.println("Whoops, something bad happened.");

                }

        }

}

How can I get it to work on linux? i'm getting
