keeping systems updated

I have several RHEL systems that are on an isolated network so I can't run up2date or yum directly on them.

What is the best way to keep these systems updated and patched?

Thanks

The only way I can think of is to burn a CD/DVD with the updates and use that. In the YUM repo's there is Centos-Media.repo that looks at cd/dvd's for updates. I would use a re-writable cd/dvd for this.

You could also create an "update depot" server that can be accessed by the isolated systems...set it so that all it does is download the update files into a repository directory...then point the servers to that system. That assumes you can cross subnets when needed.

i agree with above make a central repro but depends on the number of servers

If you're willing to buy the licenses, Redhat sells a software product called "Satellite Server" which will serve as an update server. You can run up2date from your individual servers against that, or you can remotely update your servers from the Satellite.
