I've also had problems making nagios work under Apache 2.4. When I click on
any sidebar link, instead of executing the CGI I'm presented with the
download dialog to download the CGI file. I guess CGIs have stopped working
after upgrading. I think mod_cgi does not exist for Apache 2.4, and none of
the similarly-named mods (mod_fastcgi, mod_proxy_fcgi, mod_fastcgi) seems
to be a drop-in replacement for mod_cgi.

What is the recommended way to run CGIs, specifically those needed for the
Nagios web interface, under Apache 2.4?
