文章摘要
这篇文章主要分析了一段名为`FTPFinal.pcap`的Pcap文件内容。该文件包含44个数据包,总大小为3710字节,其中包含3555个有效数据字节。捕获时间为2007年3月22日04:37:11.513913至04:37:46.007335,持续时间为34.493秒。文件使用`Wireshark.tcpdump`格式捕获,数据包被Ethernet封装。
文章还提到了文件的哈希值(SHA256、RIPEMD160、SHA1)以及数据传输速率(字节速率103 B/s,比特率824 bps)和平均包大小(80.80字节)。此外,文件的统计信息显示只有一个捕获接口,且所有数据保持严格的时序顺序。
