本项目基于libtins构建，支持节点网卡IPv4/IPv6下行、上行和上行&下行等数据包的嗅探工作，目前支持TCP、UDP、ICMP和ICMPv6等上层协议。Based on libtins, I built this project. It supports the sniffing of iPv4/IPv6 downstream、upstream and upstream & downstream packets of node network card, and currently supports upper-level protocols such as TCP, UDP, ICMP and ICMPv6.
