windows下的，一个网络嗅探器的源码，有一定的借鉴价值，可以构写自己的嗅探器了...

捕获IP数据包的小程序 支持TCP和UDP等协议。-IP packet capture program to support small TCP and UDP protocols.

高级扫描(SYN刺探)的扫描器+源代码这是图形介面下一款基于高级扫描技术(SYN刺探)的扫描器。应广大编程爱好者的要求，现在公布它的源代码。它的扫描速度在同类安全软件中是比较快的。最快可以 1s 刺探接近500个IP(远程刺探),当然那和您的网速(N重要的一点)和机器的性能有关系，在测试版中没有本地扫描的功能，在1.0中加上了。它的优势最要在于大规模的扫描，经测试它的速度比SuperScan还要快，因为SuperScan并不是基于嗅探技术的。在扫描的同时还会留下日志。SYN刺探就不会。 -High scan (SYN spying) of the source code scanner is graphics-based interface under the High scanning technology (SYN spying) scanners. Should the majority of programming enthusiasts, now published its source code. Its scanning speed in a similar security software is quite fast. The fastest 1s can gather nearly 500 IP (remote spying), and then of course, your speed (N important point) and machinery related to the performance of the beta no local scanning feature, coupled with a 1.0.SuperScanSuperScan The scan also will stay log. SYN spying would not.

iphlpapi的一个很好的例子-iphlpapi a good example

IP包监听程序 -IP packet sniffer

着是易语言的源码-is easy with the source language

能够抓获到达本机网卡的所有报文，并对其进行了初步的协议分析。-Be able to capture all the cards to reach the native packet, and its agreement to conduct a preliminary analysis.

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.
