利用Raw Socket实现Ping的模拟程序。根据 ICMP协议原理，活动主机在接收到回显请求时会返回一个 ICMP回显应答。-Raw Socket achieved using the simulation program Ping. According to the ICMP protocol works, activities in the host receives the echo request will return an ICMP echo reply.

本程序利用winpcap实现IP数据报的接受和解析-the function of this program is receving the IP packet and analyze it.

利用winpcap库文件在vc6.0下用socket实现的网络捕包分析程序，没有可视化界面，但是能分析出完成的ip报以及tcp/udp报首部-The winpcap library files in vc6.0 socket to achieve network packet capture analysis program, there is no visual interface, but analysis of the complete ip reported tcp/udp report
