Hello I have nagios 2.0b6 installed on SUSE 10 with apache2. When I try to access the page from the local machine it works great using either “http://serverip/nagios” or “http://localhost/nagios” but when I try to access the machine from another computer with serverip/nagios I get a page cannot be displayed error and not even the apache error page.
Might we see your Apache conf relevant to Nagios?
Firewall is on? Turn it off until you figure out how to enable it and still allow nagios web access.
