Red Hat Network (abbreviated to RHN) is a family of systems management services operated by Red Hat that makes updates, patches, and 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 systems can then invoke the up2date or 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. In Fedora, updates are provided by Red Hat's free yum and Advanced Packaging Tool repositories.
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. Subsequently, project Spacewalk was launched.

Famous quotes containing the words red, hat and/or network:
“He gives the impression of a strong mind which is composed and wise. His brown eye is exceedingly kindly and gentle. A child would like to sit in his lap and a dog would sidle up to him. It is difficult to associate his personality and this impression of kindness and gentle simplicity with what has occurred here in connection with these purges and shootings of the Red Army generals, and so forth.”
—Joseph Davies (1876–1958)
“Few colors last; with their eternal thirst, time and light suck on them, and they bleach the black doctor’s hat until it’s grey like a dunce’s cap.”
—Franz Grillparzer (1791–1872)
“A culture may be conceived as a network of beliefs and purposes in which any string in the net pulls and is pulled by the others, thus perpetually changing the configuration of the whole. If the cultural element called morals takes on a new shape, we must ask what other strings have pulled it out of line. It cannot be one solitary string, nor even the strings nearby, for the network is three-dimensional at least.”
—Jacques Barzun (b. 1907)
