{{Short description|Systems management service for Enterprise Linux}}

'''Red Hat Network''' (abbreviated to '''RHN''') is a family of systems-management services operated by [[Red Hat]]. RHN makes updates, [[Patch (computing)|patch]]es, and [[computer bug|bug]] fixes of packages included within [[Red Hat Linux]] and [[Red 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 these [[operating system]]s can then invoke the [[up2date]] or [[Yellow Dog Updater Modified|yum]] program to download and install updates from RHN. The updates portion of RHN is akin to other types of automatic system maintenance tools such as [[Microsoft Update]] for [[Microsoft Windows]] operating systems. The system requires a subscription to allow access to updates.

On June 18, 2008, Red Hat [[CEO]] [[Jim Whitehurst]] announced plans for the RHN Satellite software to be open-sourced following the Fedora/RHEL model.<ref name="linuxworld-news-061808">[http://www.linuxworld.com/news/2008/061808-red-hat-network-to-be.html?fsrc=rss-linux-news Red Hat Network to be open-sourced] {{Webarchive|url=https://web.archive.org/web/20080708102738/http://www.linuxworld.com/news/2008/061808-red-hat-network-to-be.html?fsrc=rss-linux-news |date=2008-07-08 }}, Chris Kanaracus, IDG News Service, 06.18.08.

Subsequently, project [[Spacewalk (software)|Spacewalk]] was launched.

== Architecture ==
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 a [[proxy server]] (Red Hat Network Proxy) that once installed at a site allows machines to securely download updates locally. Advanced [[Application lifecycle management|lifecycle 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}} the RHN Proxy Server costs $2,500 annually, and the RHN Satellite Server costs $13,500 annually, which includes the license for the embedded [[Oracle Database]].<ref>{{cite web|url=http://www.redhat.com/red_hat_network/faq/ |title=Network Satellite FAQs |publisher=Red Hat |date= |accessdate=2012-10-13}}</ref><ref>{{cite web |last=Gilbertson |first=Scott |url=http://www.redhat.com/magazine/010aug05/features/rhn_overview/ |title=What is Red Hat Network? |publisher=redhat.com |date=2005-08-10 |accessdate=2012-10-13 |url-status=dead |archiveurl=https://web.archive.org/web/20121014194650/http://www.redhat.com/magazine/010aug05/features/rhn_overview/ |archivedate=2012-10-14 }}</ref><ref>{{cite web|url=http://www.redhat.com/red_hat_network/architecture_comparison/ |title=Enterprise Linux management &#124; Compare architectures |publisher=Red Hat |date= |accessdate=2012-10-13}}</ref>
