Apache running but not serving pages.
I have just done a clean install of apache on RedHat. In the httpd.conf file, I have changed the ServerName to the IP address of the computer. From the command line, when I use xdg-open I cannot view the test page from the apache server (when using the public IP in the address bar), however I can see it when I open 127.0.0.1. I have a rule in my firewall to allow traffic on port 80.
Is there a way to debug this?
