ntopng as Flow Collector

In ntopng flows are collected through nProbe that act as probe/proxy. The communication between nProbe and ntopng happens though ZeroMQ that decouples ntopng from nProbe.

OBS nprobe kräver licens

sudo nprobe --zmq "tcp://*:5556" -i none [eth0] -n none --collector-port 2055 &
sudo ntopng -i tcp://127.0.0.1:5556
