Needs Docker. Host networking lets the container see your interfaces. Replace eno1 with your interface.
docker run -it --net=host ntop/ntopng:stable -i eno1
Replace eth1 with your interface name (run ip a).
Get the traffic to ntopng: a switch mirror port, your firewall (pfSense or OPNsense), or NetFlow from your router.
Then open http://YOUR-IP:3000 (admin / admin) and check Hosts, Flows and Alerts.
