How are you listing all the ports?

Can you show us an example so we can better help you?

Did you try something like

Code:

---

public class LowPortScanner {
  public static void main(String[] args) {
    String host = "localhost";
    if (args.length > 0) {
      host = args[0];
    }
    for (int i = 1; i < 1024; i++) {
      try {
        Socket s = new Socket(host, i);
        System.out.println("There is a server on port " + i + " of "
        + host);
      }
      catch (UnknownHostException ex) {
        System.err.println(ex);
        break;
      }
      catch (IOException ex) {
        // must not be a server on this port
      }
    }
  }
}
