a 32-bit link layer type field.The link-layer type depends on the type of link-layer header that the packets in the capture file have: 以下是数据值与链路层类型的对应表 0 BSD loopback devices, except for laterOpenBSD1 Ethernet, andLinuxloopback devices 以太网类型,大多数的数据包为这种类型。
a 32-bit snapshot length" field;The snapshot length field should be the maximum number of bytes perpacket that will be captured. If the entire packet is captured, make it 65535; if you only capture, for example, the first 64 bytes of the packet, make it 64. 7、链路层类型:32位, 数...
PCAP协议,全称Packet Capture Data File Format,是一种用于存储网络数据包的文件格式,通常以.pcap或.pcapng为扩展名。PCAP协议的定义包括了数据包的结构、捕获时间、数据长度、协议类型等信息,并将这些信息以二进制格式进行存储。PCAP协议的核心原理是通过操作系统提供的抓包接口,如libpcap或WinPcap,对网络接口设备进行监...

细节1:Cooked Capture与Ethernet 如果说使用tcpdump -i any参数,我们不会看到标准的以太头信息,我们看到的是Cooked Capture,而不是Ethernet!关键的是,Cooked Capture描述的元信息长度是16字节而不是Ethernet的14字节。以下是Cooked Capture的头示例: 这个信息可以通过LinkType来获取。为什么会有这种Cooked Capture类型的数...
The wlanPCAPWriter object writes generated and recovered WLAN medium access control (MAC) packets to a packet capture (PCAP) or packet capture next generation (PCAPNG) file (.pcap or .pcapng, respectively).
