FreeBSD上的一个sniffer程序

一个简单既网络嗅探器 可以看到源地址和目的地址-Both a simple network sniffer can see the source address and destination address

网络数据包帧听程序，大家不要用来干坏事啊。- The network data packet frame listens to the procedure, everybody do not have to use for to do the misdemeanor.

监控本地网络，捕获一段时间内以本机为源或目的地址的IP数据包，统计IP数据包的信息，列出本机到相同目的地址或同一源地址到本机且数据包协议类型相同的数据包的数量。-local network monitoring, capture for some time to the plane of the source or purpose of the IP addresses of packets, Statistics IP packet information, for this machine to the same destination address or addresses to the same source for the data packet agreement with the same type of data packets quantity.

一个完整的抓包及分析程序,对于掌握sniffer技术以及数据包结构的程序开发都非常有好处,文件好不好,请大家评论.这是有关书籍光盘里的源码:)-A complete capture and analysis procedures for the master packet sniffer technology and structure are very good developers, good documentation, please comment. This is the book CD-ROM source code :)

利用代码获得本机MAC地址。-use the access code for the MAC address.

一个很好的sniffer.基于Winpcap开发的-a good sniffers. Based on the development of the Winpcap

北京大学网络信息安全课件,段云所教授写．在这里和大家分享.-Beijing University of network information security courseware, of the cloud was taught. Here we share.

A basic exemple on how-to use "Winsock2" with Visual-C++ 6 to sniff the network without Winpcap. Also you can see how is the implementation of "WSAIoctl()" with the SDK2003. In this code, we analyse the TCP trame and show information about the ip header and contained data.-A basic exemple on how-to use "Winsock2" with Visual-C++ 6 to sniff the network without Winpcap.

在实际生活中，人们所使用的网络通信软件功能均是基于SOCKET套接字作为通信桥梁实现的。一个创建TCP服务器和客户端的程序，在VC的平台中。可以实现客户端与服务器间点对点的数据传输功能。
