Most tools tell you what traffic exists on a system.
RustNet shows you which process created it.
RustNet is a real-time terminal-based network monitor written in Rust that maps:
• Processes → network connections
• Protocols (HTTP, DNS, QUIC, TLS, etc.)
• Connection states
• Live interface bandwidth
It performs deep packet inspection to identify application protocols and hostnames, making it useful for troubleshooting unexpected outbound traffic or bandwidth-heavy processes.
If you like terminal-based tooling, this one is worth checking out.

RustNet is a great real-time network traffic analysis tool that's part of the open-source ecosystem.
