linux sock_raw原始套接字编程
sock_raw原始套接字编程可以接收到本机网卡上的数据帧或者数据包,对与监听网络的流量和分析是很有作用的.一共可以有3种方式创建这种socket 1.socket(AF_INET, SOCK_RAW, IPPROTO_TCP|IPPROTO_UDP|IPPROTO_ICMP)发送接收ip数据包 2.socket(PF_PACKET, SOCK_RAW, htons(ETH_P_IP|ETH_P_ARP|ETH_P_ALL))发送接收以太网数据帧 3.socket(AF_INET, SOCK_PACKET, htons(ETH_P_IP|ETH_P_ARP|ETH_P_ALL))过时了,不
