IP头,TCP头,UDP头,MAC帧头定义 一、MAC帧头定义/*数据帧定义,头14个字节,尾4个字节*/ typedef struct _MAC_FRAME_HEADER { char m_cDstMacAddress[6]; //目的mac地址 char m_cSrcMacAddress[6]; //源mac地址 short m_cType; //上一层协议类型,如0x0800代表上一层是IP协议 ...
第二个字段"IP",是数据包的协议。 第三个字段"192.168.27.129.46255",是source IP Address joined with the source Port。 第四个字段"192.168.27.2.53",是destination IP Address joined with destination Port and then some information about the packet. 2、-v -vv -vvvverbose, very verbose, very very...

Capture, analyze, and troubleshoot network traffic with tcpdump. Monitor performance, enhance security, and resolve connectivity issues effortlessly
without a directional prefix. The MAC address support seems to give a syntax error unless "ether hh:hh:hh:hh:hh:hh" is preceeded by "src" or "dst". I assume that I could get the desired result with something like "src ether hh:hh:hh:hh:hh:hh or dst ether hh:hh:hh:hh:hh:hh...
2).ARP欺骗完成后,网关的ARP记录会有两记录的MAC地址是相同的,分别 是:192.168.1.11(11-11-11-11-11-11)和192.168.1.77(11-11-11-11-11-11),这样可能会比较明显,可以把A自己在网关的ARP缓存改了:192.168.1.11(01-10-01-10-01-10,乱写一个),但这样会有两个问题:一个是这个MAC是乱写的,局域网内根本...
