下面代码哪错了，socket就是连不起来：



import java.io.*;

import java.net.*;



class TransClient{

	public static void main(String[] args) throws Exception{

		InetAddress ia = InetAddress.getLocalHost();

		Socket s = new Socket(ia.getHostAddress(), 10005);

		

		//源：键盘

		BufferedReader bufr = 

				new BufferedReader(new InputStreamReader(System.in));

		BufferedReader bufIn = 

				new BufferedReader(new InputStreamReader(s.getInputStream()));

		BufferedWriter bufOut =

				new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));

		

		String line = null;

		while((line = bufr.readLine()) != null){

			if("over".equals(line)){

				break;

			}

			bufOut.write(line);

			bufOut.newLine();

			bufOut.flush();

			

			String str = bufIn.readLine();

			System.out.println("Server: " + str);

		}

		

		bufr.close();

		s.close();

	}

	

}

public class TransServer {



	public static void main(String[] args) throws Exception {

		// TODO Auto-generated method stub

		ServerSocket ss = new ServerSocket(10005);

		Socket s = ss.accept();

		String ip = s.getInetAddress().getHostAddress();

		System.out.println("IP: " + ip + "...connected...");

		

		BufferedReader bufIn =

				new BufferedReader(new InputStreamReader(s.getInputStream()));

		BufferedWriter bufOut =

				new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));

		

		String line = null;

		while((line = bufIn.readLine()) != null){

			//从客户端读到文本，然后转成大写形式反馈给客户端.

			bufOut.write(line.toUpperCase());

			bufOut.newLine();

			bufOut.flush();

		}

		s.close();

		ss.close();

		

	}
