Usage

Container is using network host mode.

If you want to build from sources:

docker-compose build

using docker-compse.yml, notpng and redis volumes are persistent:

mkdir -m 777 /var/lib/ntopng/
docker-compose up -d

• navigate to 0.0.0.0:27833
• set admin password ( default login/pwd is admin/admin)

env value NTOP_UID and NTOP_GID are available to match user and group of local mounted volumes (./data/notpng, ./data/redis)

Note that with netplan.io, it is not possible to set an interface in promiscous mode, ie you can't monitor all flows, but only flows from or to the host. if anyone knows how to do with netplan, please let me know.

This command may help to set the interface to promiscuous mode: ip set link <interface> up promisc on
