We are installing Ngaios XI on RHEL5 update 3, we dont have RHN subsription for this.

Then when we are installing ./fullinstall getting the below error. Please help us on this. Thanks in advance.

Nagios XI Full Installer
========================

This script will do a complete install of Nagios XI by executing all necessary sub-scripts.

IMPORTANT: This script should only be used on a 'clean' install of CentOS or RedHat. Do NOT use this on a system that has been tasked with other
purposes or has an existing install of Nagios Core. To create such a clean install you should have selected ONLY the 'Base' package in the OS installer.

RHN registration is a requirement for XI installation on Redhat. If you're not able to register your copy of Redhat, we recommend using CentOS.

Thanks for your Reply, But is there way we can edit the script to not ask for the RHN registration.

No.

You could edit the script to not ask, but then it would fail because it couldn't install required components.

[ukggupta]

yes, you can change the 0-yum script and comment registration related lines.

Thanks

Yes, but then there will be several subcomponents in XI that will not work because the prerequisites aren't being installed. We're not putting that sanity check in the RHEL installer just because we want you to register. The install will be BROKEN from day one.
