This manual page documents the nutop command.

Nutop is to be used by administrators willing to view users activity on a NuFW server, in real time. The display is designed to look a lot like the well known top command, as far as general layout is concerned.

The default configuration file (containing SQL connections parameters) is located at /etc/nufw/nutop.conf. If decided to customize it to their needs, care should be taken about file permissions on that file, as it might let any user of the system access to the NuFW connection tracking database.
