【Python】测试dpkt解析pcap
1、前言
本想借助dpkt解析mail、dns、http来辅助分析pcap包进行分析，查阅资料学习却发现并不如使用scapy那么方便。
dpkt是一个python模块，可以对简单的数据包创建/解析，以及基本TCP / IP协议的解析，速度很快。
dpkt 手册
看官方手册发现DPKT是读取每个pcap包里的内容，用isinstance判断是不是有IP的包，再判断是属于哪个协议，对应的协议已经封装好API如果发现可以匹配某个协议API就输出来相关值。
想要扩展这个源码还需要去学习一下协议相关的字段含义。
API调用：
https://dpkt.readthedocs.io/en/latest/api/api_auto.html#module-dpkt.qq
在手册中找到了在Github中部分API的示例代码，具备参考价值。
2、手册例子
以下代码是手册中的例子，通过查询发现inet_pton无法直接使用，按照网络上的解决方法修改了一下。
打印数据包
使用DPKT读取pcap文件并打印出数据包的内容。打印出以太网帧和IP数据包中的字段。
