trombik.ntopng

ansible role for ntopng.

Notes for Ubuntu users

ntopng from the official distribution package repository and one from the ntop.org has differences. The major one is the path to ntopng.conf: /etc/ntopng.conf for the former and /etc/ntopng/ntopng.conf. The default of the role is /etc/ntopng/ntopng.conf.

This variable is used for overriding defaults for startup scripts. In Debian variants, the value is the content of /etc/default/ntopng. In RedHat variants, it is the content of /etc/sysconfig/ntopng. In FreeBSD, it is the content of /etc/rc.conf.d/ntopng. In OpenBSD, the value is passed to rcctl set ntopng.
