ARP模拟程序：本程序分为两个子程序，分别是arpsrc ,arptarget ；arpsrc用来模拟一台主机用来发送一个ARP的询问包，arptarget用来模拟接受ARP包的主机，对不同的ARP询问包进行处理。-ARP simulation program: This program is divided into two subroutines, namely arpsrc, arptarget arpsrc used to simulate a host to send an ARP inquiry packet, arptarget used to simulate the acceptance of ARP packet the host, asked whether the different ARP packet for processing.

snort有三种工作模式：嗅探器、数据包记录器、网络入侵检测系统。嗅探器模式仅仅是从网络上读取数据包并作为连续不断的流显示在终端上。数据包记录器模式把数据包记录到硬盘上。网路入侵检测模式是最复杂的，而且是可配置的。我们可以让snort分析网络数据流以匹配用户定义的一些规则，并根据检测结果采取一定的动作
