利用ARP协议获得局域网内活动主机物理地址

Sniffer原理及开源代码,包含几个文档的说明，源码，简单易懂！-Sniffer principle and the open source code, contains several documents that source, easy-to-read!

需要实现的功能目标是： 1． 网卡、适配器的显示和选择 2． 获取局域网内活动主机 3． 数据包的接收 4． 数据包的解析 5． 选择活动主机列表中一个或多个主机 6． 捕获数据包并进行概要信息显示 7． 显示IP流量统计信息 -Need to achieve functional objectives are: 1. Card, adapter display and option 2. Activities within the LAN hosts to obtain 3. Packet reception 4. Packet parsing 5. Select list of active hosts one or more hosts 6. Capture data packets and carry out summary information display 7. Show IP Traffic Statistics

该软件能很好的对网络的流量进行查看,功能很好,但是有些小问题在下没有能解决,希望各位大哥能给小弟好的建议-The software will be good for the network traffic for a look and function very well, but some minor problems can be resolved without the next, I hope the younger brother can give good advice

udpcapture。利用winpcap编程实现抓取以太网上的UDP报文，并打印报文长度和时间，以及UDP报文的源IP和目的IP。这是利用winpcap编程的比较简单的例子，在此基础上修改源码可以实现所要求的复杂功能-udpcapture. Programming using WinPcap crawl Ethernet UDP packet, and print message length and time, as well as the UDP packet

该程序捕获所有的数据包，并分析以太网头部、IP头部和TCP头部。-capture all of the procedures of data packets, and analyze Ethernet head, the head of IP and TCP head.

C语言版的HTTP包头解析，符使用实例。-C language version of the HTTP header parsing, address the use of examples.

VC中利用钩子记录中文字符 -VC hook records the use of Chinese characters

winpcap 测试程序, 一个简单的winpcap小例子, 仅供学习参考-WinPcap test procedure, a simple WinPcap small example, only the reference study
