sniffer is designed for network troubleshooting.
It can be started at any time to analyze the processes or connections causing increases in network traffic without loading any kernel modules. By the way, the TUI of it is responsive that can fit with terminals of all sizes automatically.
sniffer manipulates gopacket to sniff the interfaces and record packets’ info. gopacket wraps the Golang port of libpacp library, and provides some additional features. One of the projects that inspired the sniffer is bandwhich, which has a sophisticated interface and multiple ways to display data, but it does not support BPF filters. Another one is nethlogs, which supports BPF filters, but can only view data by process, without connections or remote address perspective. sniffer combines the advantages of those two projects also adhering a new Plot mode.
sniffer depends on the libpcap library to capture user-level packets.
