Welcome to the nsca-ng package for Debian GNU/Linux! You can contact the nsca-ng maintainers at: pkg-nagios-devel@lists.alioth.debian.org Enabling the daemon ------------------- To enable the daemon set NSCA-NG in /etc/default/nsca-ng-server to "yes". Using nsca-ng ------------- If you are missing your command socket it is a good idea to read /usr/share/doc/icinga2/markdown/14-features.md.gz (the "External Commands" section). The daemon is bound to localhost by default, you probably want to change this in "/etc/nsca-ng/nsca-ng.local.cfg" when you are done with your configuration.
