Remote update of systems - how do I block this?



Hi All,

I found out yesterday that there is an option to remotely update your system
with the latest Red hat patches.  What is the configuration for this and how
do I block it?  Specifically, what settings do I need to apply to our
corporate firewall to block the inbound connections?
