捕获ip数据包的小程序源码，可以指定数据包的源地址，协议，目的地址等等。...

Ethernet帧的封装与解析 帧的封装：用户输入任意一段信息，以回车作为结束。然后程序将这段信息作为帧的数据字段封装到数据帧中。并相应填充帧的其他字段。 帧的解析：从用户输入的文件中读取帧，并对其进行解析。通过重新计算CRC-8校验和，判断该帧是否会被接受。最终在终端输出帧的相关信息。 -Ethernet Frame CRC-8

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.
