[`fddi' is actually an alias for `ether'; the parser treats them identically as meaning ``the data link level used on the specified network interface.'' FDDI headers contain Ethernet-like source and destination addresses, and often contain Ethernet-like packet types, so you can filter on the...
(See `ip proto' above for the meaning of protocol.) Note that this primitive chases the protocol header chain. ether broadcast True if the packet is an Ethernet broadcast packet. The ether keyword is optional. ip broadcast True if the packet is an IPv4 broadcast packet. It checks for both...
其实在pcap_create函数和pcap_activate函数之间还可以调用pcap_set_buffer_size函数设置内核缓冲区的大小,这个函数我们可以在opentest.c文件中看到它的调用方法。我也会在下文中进行讲解。 Libpcap源码为了支持多个操作系统,代码错综复杂,你搜一下pcap_create函数,有很多地方定义了该函数,但是我们是在Linux系统下进行源码...
True if the packet is an IPv4 or IPv6 packet of protocol type protocol. (See `ip proto' above for the meaning of protocol.) Note that this primitive does not chase the protocol header chain. ah, esp, pim, sctp, tcp, udp

* 0 from pcap_read() meaning "no packetsarrived before * the timeout expired", so we map it to-2 so you can * distinguish between an EOF from a savefileand a * "no packets arrived before the timeoutexpired, try * again" from a live capture. ...
* pcap_offline_read()meaning"end offile".*/return(p->read_op(p,1, pcap_oneshot,(u_char *)&s));}这个函数没有什么好说的,最终调用的函数也是read_op及pcap_read_packet函数,和上面的那2个函数类似。 Int pcap_loop(pcap_t *p, int cnt, pcap_handler callback,u_char *user){register int ...
需要注意的是,tcp,udp,icmp这些标识符同时也是关键字,所以必须当转义字符处理,类似C风格的\\,还有要注意的是:此原语不捕获协议头链 ip6 protoprotocol 当数据包是一个属于IPv6类型的协议的数据包时成立.注意这个原语是不能捕获协议报头链的 ip6 protochainprotocol ...
