PCAP Capture File Format 2023 介绍 在19世纪80年代后期,Van Jacobson, Steve McCanne 和其他人在位于Lawrence Berkeley National Laboratory的Network Research Group中开发了tcpdump——用来捕获和分析网络流。读取网络流,然后通过libpcap写入到文件。 常规文件结构 一个pcap文件由一个文件头组成,后续跟着0填充或者多个...
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。
capinfos-c<文件名> 对应在wireshark页面的统计(Statistics)-->捕获文件属性(Capture File Properties),也有这部分信息: 2)显示捕获文件的大小(-s) 以字节为单位,统计包文件大小: 代码语言:bash AI代码解释 capinfos-s<文件名> 如图,File size即为文件大小字段,如果文件过大会自动进行单位转换。 3)显示所有数据...
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...
