Installation guide
Network bandwith is important for communication among Satellites, Proxies, and Clients.
To accomodate high volume traffic, Red Hat recommends a high bandwidth on a network
capable of delivering packages to many systems and clients. As a guide, Red Hat provides
a set of estimates for package transfer from one system to another over various speeds.

Red Hat recommends at least a 100Mbps network speed for minor and major releases. This
avoids timeouts for transfers longer than 10 minutes. All speeds are relative to your network
setup.
Red Hat recommends that the system running the code should not be publicly available. Only system
administrators should have shell access to these machines. All unnecessary services should be
disabled. Use ntsysv or chkco nfi g to disable services.
