Glossary

Registered System

A system that is registered with Red Hat Network. Also known as a client system.

Red Hat Network Daemon

The RHN client daemon (

rhnsd

) that periodically polls Red Hat Network for updates and noti-

fications.

Red Hat Network Registration Client

The RHN client application (

rhn_register

) that collects information about the client system,

creates a

System Profile

and

Digital Certificate

, establishes a connection with the Red Hat

Network servers, and registers the system with Red Hat Network.

Red Hat Update Agent

The RHN client application (

up2date

) that allows users to retrieve and install all updated pack-

ages for the client system on which the application is run. Use the

Red Hat Update Agent

Configuration Tool

to configure its preferences, including whether to install the packages after

they are downloaded.

RPM

A software package manager that was developed by Red Hat. It can be used to build, install,

query, verify, update, and uninstall software packages. All software updates from RHN are de-

livered in RPM format.

RPM Database

Each Red Hat Enterprise Linux system has an RPM database that stores information about all

the RPM packages installed on the system. This information includes the version of the package,

which files were installed with the package, a brief description of the package, the installation

date, and more.

RPM Update

Red Hat Network option to deliver the RPM packages based on the

Errata Alert

list to a client

system without user intervention. If this feature is selected, packages are delivered through the

Red Hat Network Daemon

running on the client system.
