eavesdropping, the use of java development.

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.

能让捕获IP层的网络封包-can capture IP network layer packet

文档，教你如何循序渐进使用WINPCAP-Document, teach you how to use step-by-step WINPCAP ..

一个网络监控的源代码，vb语言编写，非常好，共享给大家-A network monitoring the source code, vb languages, very good, to share to everyone

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

c# 的源码，ip包的过滤。还不赶快下！-the source, ip packet filtering. Upshot under!

这是一个比较完善的网络协议包的捕获和解析的源码数据包。网络数据包的捕获采用libpcap。非常不错的，大家共同学习进步-This is a relatively perfect network protocol packet capture and analysis of the source packets. Capture network packets using libpcap. Very good progress in learning the common U.S.
