A CLI for displaying network utilization by process, connection, and remote host ↦
bandwhichsniffs a given network interface and records IP packet size, cross referencing it with the
/procfilesystem on linux or
lsofon MacOS. It is responsive to the terminal window size, displaying less info if there is no room for it. It will also attempt to resolve ips to their host name in the background using reverse DNS on a best effort basis.
This looks much better than me fumbling through
lsof’s man page for ten minutes and then giving up.
