[b]1. Create a client[/b]
package com.chris.client;
import java.io.IOException;
import java.io.PrintStream;
import java.net.Socket;
import java.net.UnknownHostException;
public class Client {
public static void main(String[] args) throws UnknownHostException, IOException {
Socket client = new Socket( "192.168.104.164", 8888 );
System.out.println( client.isBound() );
PrintStream writer = new PrintStream( client.getOutputStream() );
writer.println(" HelloLinux, I'm come from Windows environment");
writer.close();
}
}
[b]2. Create a Server[/b]
package com.chris.server;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.ServerSocket;
import java.net.Socket;
public class Server {
public void createServer() throws IOException, InterruptedException {
ServerSocket server = new ServerSocket( 8888 );
Socket s = server.accept();
BufferedReader reader = new BufferedReader(new InputStreamReader(s
.getInputStream()));
char[] buffer = new char[1024];
StringBuilder sb = new StringBuilder(1024 * 1024);
int size = -1;
while ((size = reader.read(buffer)) != -1) {
String temp = new String(buffer, 0, size);
sb.append(temp);
}
System.out.println( sb.toString());
reader.close();
}
public static void main(String[] args) {
Server server = new Server();
try {
server.createServer();
} catch (IOException e) {
e.printStackTrace();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
以上的程序如果只是在本地測試，那麼可以正常的通過， 但是當我把服務器程序放到Linux系統下（另外一臺機器）， 而Client部分放到Windows平臺下跑時，系統就包下面的異常了
Exception in thread "main" java.net.NoRouteToHostException: No route to host: connect

後面通過查找相關資料， 發現是Linux防火牆沒有關的的原因導致的。
[b]3. Close firewall on Linux[/b]
到Shell窗口下，鍵入service iptables stop, 重新聯接， OKay了
如果要重新啓動防火牆則輸入service iptables start
總結：
是否有其它的方式沒有， 如果有， 請不賜教：）
