Nagios Directory Index Forbidden by Options Directive
After installing Nagios on a Raspberry Pi 2 Model B by following these installation instructions, I ran into a irritating problem. When trying to connect to Nagios I got the authentication dialog, but after that I got an access error in my browser.
I searched around on Google but couldn’t find a solution. But after a lot of fiddling with Apache2 I found a solution. There’s a problem with the standard installation of the file in /etc/apache2/conf.d/nagios.conf created by make install-webconf
