portop is an htop-style terminal UI for the TCP and UDP sockets on a machine. For every port it shows the process, its systemd unit or Windows service, its Docker, Podman or Kubernetes container, who can reach it and what the firewall does with it, and it lets you inspect or stop the owner from the keyboard. It runs on Linux, macOS and Windows, in the terminal, in a browser or inside Cockpit. See
