能让捕获IP层的网络封包

Windows 2000下IP地址过滤源码-under Windows 2000 source IP address filtering

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
