pstat监视网络来往包
监视网络来往包，纪录收到的包，需要pcap支持，可工作在windows和linux下。
可根据对方端口和ip来过滤，过滤方式有包含和不包含两种方式可选，纪录方式有裸数据、流量和文本。
本程序可用来做端口流量统计，或者详细的web请求日志，用于事后分析。
用法:
pstat [-f <defaults file>] [-i <local nets>] [-d <data dir>] [-e] [-g <core>] [-n mode] [-i <iface|pcap file>] [-d <path>]
[-v] [-x ] [-C] [-p] [-w] [-B <filter>] [-A <mode>] [-c <ip>] [-s <length>]
Options:
[--interface|-i] <interface|pcap> | Input interface name (numeric/symbolic)
| or pcap file path
