Hi Neririn:
The 'best' way, at least to build and share the results, is to use a RH 7.3 box with the devel packages to compile. They do NOT come on SME in the stock install and present major security risks esp on a SME used as a web server as well as devel (not a good idea).
As far as the specific requires(from nagios.org): "System Requirements
The only requirement of running Nagios is a machine running Linux (or UNIX variant) and a C compiler. You will probably also want to have TCP/IP configured, as most service checks will be performed over the network.
You are not required to use the CGIs included with Nagios. However, if you do decide to use them, you will need to have the following software installed...
A web server (preferrably Apache)
Thomas Boutell's gd library version 1.6.3 or higher (required by the statusmap and trends CGIs)"
http://nagios.sourceforge.net/docs/1_0/about.html#requirementsIf you get the plugin package to compile, please let me know. I would like to complete a contrib for SME of Nagios.
