java socket 发生ConnnectException：connection timeout：connect

altairheat 2013-05-10 08:46:31

小弟搞了一天了最近想搞个聊天工具但因为刚接触网络方面的今天调试了一天都没搞好
问题是这样的：
服务端 ip：172.16.29.124
客户端 ip和服务端同属于校园内网的
结果每次当两台不同电脑：客户端一连接服务端成功，客户端马上就出现题目中的
ConnnectException：connection timeout：connect，
然后服务端就出现SocketException：reset
通过错误信息追踪是client.java的第15行就是客户端socket连接那里！

如果服务端和客户端是同一台电脑，就是本机连接本机的话一秒不用就连上了。
代码较短，这里就贴一下吧
服务端代码Server.java

package server;



import java.io.*;

import java.net.*;



public class Server

{

    public static void main(String args[]) throws IOException

    {

        InetAddress IP=InetAddress.getLocalHost();

        System.out.println(IP.getHostAddress());

        ServerSocket serverSocket=new ServerSocket(10000);

        while(true)

        {

            Socket socket=serverSocket.accept();

            System.out.println("Client connected");

            ServerThread serverThread=new ServerThread(socket);

            serverThread.start();

            System.out.println("IO started");

        }

    }

}

ServerThread.java:

package server;



import java.io.*;

import java.net.*;

import java.util.Scanner;



public class ServerThread extends Thread implements Runnable

{

    private Socket socket;

    

    public ServerThread(Socket socket)

    {

        this.socket=socket;

    }



    @Override

    public void run()

    {

        try

        {

            BufferedReader netInput = new BufferedReader(new InputStreamReader(socket.getInputStream()));

            PrintWriter netOutput = new PrintWriter(socket.getOutputStream());

            //do sth

        }

        catch(Exception e)

        {

            e.printStackTrace();

        }

    }

}

客户端client.java

package client;



import java.io.*;

import java.net.*;

import java.util.Scanner;



public class Client

{

    public static void main(String args[])

    {

        try

        {

            InetAddress IP=InetAddress.getLocalHost();

            System.out.println(IP.getHostAddress());

            Socket socket=new Socket("172.16.29.124",10000);

            System.out.println("Server found");

            BufferedReader netInput = new BufferedReader(new InputStreamReader(socket.getInputStream()));

            PrintWriter netOutput = new PrintWriter(socket.getOutputStream());

            //do sth

        }

        catch(Exception e)

        {

            e.printStackTrace();

        }

    }

}
