Red Hat Network (abbreviated toRHN) is a family of systems-management services operated byRed Hat. RHN makes updates,patches, andbug fixes of packages included withinRed Hat Linux andRed Hat Enterprise Linux available to subscribers. Other available features include the deployment of custom content to, and the provisioning, configuration, reporting, monitoring of client systems.
Users of theseoperating systems can then invoke theup2date oryum program to download and install updates from RHN. The updates portion of RHN is akin to other types of automatic system maintenance tools such asMicrosoft Update forMicrosoft Windows operating systems. The system requires a subscription to allow access to updates.
On June 18, 2008, Red HatCEOJim Whitehurst announced plans for the RHN Satellite software to be open-sourced following the Fedora/RHEL model.[1]Subsequently, projectSpacewalk was launched.
In the basic subscription model the information about a managed host is stored on Red Hat's servers, and updates get downloaded directly from those servers as well. For an organization that manages multiple machines this is inefficient bandwidth-wise. Red Hat offers aproxy server (Red Hat Network Proxy) that once installed at a site allows machines to securely download updates locally. Advancedlifecycle management; provisioning features, like bare metal PXE boot provisioning; and monitoring features (e.g. centralized CPU and disk usage) cannot be done over the Internet to the hosted RHN servers. These features require a RHN Satellite Server running locally. As of December 2009[update] the RHN Proxy Server costs $2,500 annually, and the RHN Satellite Server costs $13,500 annually, which includes the license for the embeddedOracle Database.[2][3][4]
