The RHN Package Manager is a command line tool that allows an organization to serve local packages associated with a private RHN channel through the RHN Proxy Server. If you want the RHN Proxy Server to update only official Red Hat packages, do not install the RHN Package Manager.

To use the RHN Package Manager, install the rhns-proxy-package-manager package and its dependencies.

Only the header information for packages is uploaded to the RHN Servers. The headers are required so that RHN can resolve package dependencies for the client systems. The actual package files (*.rpm) are stored on the RHN Proxy Server.

The RHN Package Manager uses the same settings as the Proxy, defined in the /etc/rhn/rhn.conf configuration file.
