一个关于 socket 的问题

Question

初学JAVA，编了一个socket的聊天程序，但在自己机子上运行的时候就卡上了，老提示 java.net.ConnectException: Connection refused: connect
请解答一下困惑，谢谢
服务端的RUN代码如下
  public void run() {
    String lineSeparator=System.getProperty("line.separator");
    try {
      serverSocket=new ServerSocket(3423);
      socket=serverSocket.accept();
      cin=new BufferedReader(new InputStreamReader(socket.getInputStream()));
      cout=new PrintWriter(socket.getOutputStream());
      if(socket!=null)
      {
         textArea1.append("系统消息：客户端成功接入!"+lineSeparator);
         button1.setEnabled(true);
      }
      Receiver r=new Receiver();
      Thread t=new Thread(r);
      t.start();
    }
    catch (Exception ex) {
      textArea1.append(ex.toString()+lineSeparator);
    }
  }客户端如下
  public void run() {
    String lineSeparator=System.getProperty("line.separator");
    try {
      socket=new Socket(InetAddress.getByName("127.0.0.6"),3423);
      cin=new BufferedReader(new InputStreamReader(socket.getInputStream()));
      cout=new PrintWriter(socket.getOutputStream());
      button1.setEnabled(true);
      Receiver r=new Receiver();
      Thread t=new Thread(r);
      t.setName("NewQQClient");
      t.start();
      textArea1.append("系统消息：成功连接到服务器!"+lineSeparator);
      button3.setEnabled(false);
    }
    catch (Exception ex) {
      textArea1.append(ex.toString()+lineSeparator);
    }
  }
