Portspegling
Det finns olika sätt att få den speglade trafiken till ntop.
- vSwitch: Promiscuous mode
- dvSwitch: Distributed Port Mirroring
- Fysisk switch: SPAN/RSPAN/ERSPAN
Listener Port
echo "auto eth1" | sudo tee -a /etc/network/interfaces echo "iface eth1 inet manual" | sudo tee -a /etc/network/interfaces
NetFlow
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, se även Cisco NetFlow.
sudo nprobe --zmq "tcp://*:5556" -i none [eth0] -n none --collector-port 2055 & sudo ntopng -i tcp://127.0.0.1:5556
