基于 Raw Socket 的 数据包捕获程序。支持 TCP/UDP/ICMP,支持端口及IP 过滤。-Raw Socket-based packet data capture process. Supports TCP / UDP / ICMP, IP and port support filtering.

In this article, I will explain how to create UDP packets and then send them to a remote server through the Internet using WinPCap for Windows. The code has been tested to work with Windows XP SP2 and Vista SP1 on Linksys routers, and on Toshiba mode

UDP扫描原理与TCP扫描原理不同，UDP扫描是通过向对方UDP端口发送数据，然后根据对方ICMP返回数据进行判断。接收ICMP数据包只能采用RAW Socket接收到所有的数据包，然后从中过滤出哪一个数据包是对方返回的，进而判断出对方端口是否处于开状态。-UDP scanning principle and TCP scanning works differently, UDP port scans are sent via UDP to the other data, and then re
