Red Hat Network Satellite Server

RHN Satellite Server allows organizations to utilize the benefits of Red Hat Network without having to provide public Internet access to their servers or other client systems. System Profiles are stored locally on the customer's RHN Satellite Server. The Red Hat Network website is served from a local Web server and is not accessible from the Internet. All package management tasks, including Errata Updates, are performed through the local area network.
