Sniffer relies on the libpcap library to capture user-level packets hence you need to have it installed first. And sniffer manipulates the API provided by gopsutil directly on Windows. On macOS, the lsof command is invoked, which relies on capturing the command output for analyzing process connections information. But both need to aggregate and calculate the network traffic of the process by matching the inode information under /proc/$/fd. Since that approach is more efficient than reading the /proc/net/* files directly. ![]() On Linux, sniffer refers to the ways in which the ss tool used, obtaining the connections of the ESTABLISHED state by netlink socket. ![]() sniffer combines the advantages of those two projects also adhering a new Plot mode. Another one is nethlogs, which supports BPF filters, but can only view data by process, without connections or remote address perspective. 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. gopacket wraps the Golang port of libpacp library, and provides some additional features. Sniffer manipulates gopacket to sniff the interfaces and record packets' info. By the way, the TUI of it is responsive that can fit with terminals of all sizes automatically. It can be started at any time to analyze the processes or connections causing increases in network traffic without loading any kernel modules. Sniffer is designed for network troubleshooting. A modern alternative network traffic sniffer inspired by bandwhich(Rust) and nethogs(C++).
