Offline updates - best practice?
Here's the situation:
We have a RHEL server running in an environment with no internet access. I would like to keep this server updated but am obviously unable to connect it to RHN.
What is the best practice for performing remote/offline updates? Do I just build another server that has internet access and download all required updates? And how can I determine what updates I need without connecting the server to RHN?
And how will this work with subsriptions? I mean, I have 1 subsription, but building another RHEL server to download the updates would require another subscription right?
What have other people done? Thanks for the advice in advance.
