Installing nagios

We will probably be using RHEL5 or RHEL6 for online computers behind a firewall. I tried installing nagios on Linux box somov-l1 which was on the 36-subnet. The installation using sudo yum install nagios failed because RHEL5 does not include nagios. Then I downloaded an RPM epel-release-5-4.noarch.rpm and installed it, which added Fedora EPEL repositories to the /etc/yum.repos.d directory on somov-l1 Linux-box. But because there was not access to the Fedora mirror list or the mirrors I was not able to do the installation.

Well, the RPM installation worked.
