网络监听，可以查到包源及目的地址，可以分析数据包的内容...

客户端程序。该程序首先与相应服务器连接。然后接收用户从标准输入（键盘）输入的字符串，再将字符串发送给服务器，接收服务器发回的信息并显示。之后，继续等待用户输入直至用户输入Ctrl-D。当收到用户输入Ctrl-D后，客户关闭连接并退出。-client. The procedure first with the corresponding server connections. Users then receive from the standard input (keyboard) and input string, and then a string sent to the server, server to receive the information and display. After continue to wait until the user input of user input Ctrl-D. When users type Ctrl-D, customers close the connection and exit.

关于网络聊天的代码，看看吧-Those are some codes about webchat.

使用python编写的ping程序，ping大家都比较清楚了吧-Ping prepared using procedures python

里边有几个网络编程实例,还有一些可以用来传输用的程序,都是经过测试通过的,非常好用哦.-It includes several instances about network programming ,and several programs which can be used to transfer things.They were tested,and they are powerful.

含括了 MC35i开发的全部资料，是开发GPRS的好帮手，希望对各位有用！-Trinidad encompassing the development of all the information, the development of GPRS is a good helper, and I hope to you and useful!

利用TCPIP实现简单的客服务器模式,用C语言实现-TCPIP simple use of the passenger server model, with C language

C2风格的局域网聊天程序，实现局域网中两个Client聊天。这个程序分Server和Client两部分，但是和网上流行的Server与Client聊天不同，它是实现的Client与Client 聊天，Server 仅仅提供消息转发功能，因此执行程序时，首先必须有两台以上的电脑来执行，必须保证两个Client（Client程序是相同的，因此只要复制两个Client就行）在不同的局域网上的电脑，局域网中只要有一个Server就行，通过输入IP以及确认码（其实就是端口号，要保证两个Client的端口号相同，且两个Client的IP地址不同，即不在同一电脑上），就能实现一个Client和另一个Client聊天（当然Server必须运行，且必须按提示输入信息），本程序基于UDP协议，并且利用多线程编程实现了程序的背景音乐（系统的Beep声音必须打开才能听见）以及正常退出功能（点右上角的“差”是非正常退出！），当初设计的时候使得两个Client端口号必须相同，今后会设计出两个Client端口号不同，这样就能在一台机子上执行程序了。 -This program has the function that it can make two Clients communicate on the LAN.The program has Server and Client two parts.However,it is different from the popular CS chat program which has the function of communicating from Server and Client on the web.It makes two Clients chat.The server only be assigned to transmit messenger from one Client to another.So,you should have more than two Computer to run the program,and to ensure that two Clients on the different Computers which is on the same LAN.The LAN has one Server is OK

使用VC++6.0实现的一个网络通信小程序-Use VC++ 6.0 realize a network of small procedures

C# SOCKET编程，异步通讯方式，提供客户端和服务端。-C# SOCKET programming, asynchronous means of communication to provide client and server.

这是一个Tcp协议的网络引擎，包括两个部分： a、服务器采用完成端口模型，提供了丰富的接口函数 b、客户端采用三线程加重叠Io模型，速度快，稳定 都采用回调函数接收数据，是对网络Tcp模型Socket的完整封装，所有代码在Windows2000下测试通过，并已应用到很多现有的中型网络系统中。-This a remarkably agreement Network engines, including two parts : a server used to complete port model, a rich interface function b, client using three overlapping threads increases Io model, speed and stability using a callback function to receive information, the network model DEC Socket complete package, all of the code in the test under Windows 2000, and has been applied to many existing medium-sized network systems.
