New CentOS installation giving problems - can't change

Hi all,

I’m new to Nagios, and installed it on CentOS 5.2 via “yum install nagios”, then logged into the web interface and want to change the configurations, but get the following error:

[code]
It appears as though you do not have permission to view the configuration information you requested…

If you believe this is an error, check the HTTP server authentication requirements for accessing this CGI
and check the authorization options in your CGI configuration file.[/code]

Can someone please tell me how to fix this?

You should not install nagios. Its not a package to do so. Its a tool. You follow the quick installation guide in the documentation part of www.nagios.org
