Client程序同样分别创建一个TCP socket 和一个UDP socket，首先client使用TCP socket连接TCP Server。 连接成功后显示提示信息； 然后client端向TCP Server发送“GET UDP PORT”字符串，Server收到后向client回送自己的UDP Server 端口号（即Client端仅知道TCP Server的端口号而不知道UDP Server的端口号）； client在收到UDP Server的端口号后, 为用户显示3个选项： 1．“Get current time（TCP）”服务器时间 2．“Echo Mode（UDP）”回显6 3．“Exit the program”. -Client program also creates a TCP socket, respectively, and a UDP socket, the first client to use TCP socket connection TCP Server. After a successful connection displays a prompt message and then client-side to the TCP Server sends " GET UDP PORT" string, Server receipt back to the client to send their UDP Server port number (ie, Client-side only to know the TCP Server" s UDP port number do not know Server" s port number) client received UDP Server port number, in order to the user three options: 1. " Get current time (TCP)" server time 2. " Echo Mode (UDP)" echo 63. " Exit the program" .

一个网络抓包工具，支持三种协议(TCP,UDP和ICMP)的数据包抓取,使用winsock API编写，可以很方便的扩展自己的程序。可以把每种抓取的协议数据保存到日志记录文件中。抓包速度比较快，以树形列表给与分析，可以查看原始数据包。该程序需要在Windows XP/2000/NT操作系统上，并且有管理员权限。-1 PacketCapture tools to support the three kinds of protocols (TCP, UDP and ICMP) packet capture, using the winsock API write, you can easily expand their programs. Can be saved for each crawl of the protocol data to a log file. Ethereal" s faster, in order to give the analysis of tree list, you can view the original packets. The program requires Windows XP/2000/NT operating system and has administrator privileges.
