Errata

Errata is the name for the collection of all updates and patches. Red Hat 

distinguishes between three types of errata:

Security updates

Bugfix updates

Enhancement updates

These three sorts of errata each have their own priority for an application. 

Security updates should be applied immediately, Bugfix updates if necessary, 

and Enhancement updates when needed.

Activation key

An activation key is used to register the system, entitle the system to a service 

level, and subscribe the system to specific channels and system groups through 

the command line utility 

rhnreg_ks

. These keys can only be created for 

Management and Provisioning entitlements. The keys are generated in the 

satellite server.

First impressions

In this section we describe some standard actions in a satellite server. This gives 

a good first impression of how the tool works and what it can do.

The standard actions we describe are:

Adding a user in the satellite server

Connecting a client to the satellite server and configuring the system

Creating a system group 

Adding a system to a group

Adding a channel to the server

Performing a scheduled action on the client system

When logging onto the satellite server using the administrative user, one gets the 

page shown in Figure A 4 on page 169. This shows tabs at the top that take you 

to the different areas in the server. These areas are:

Systems   Here all modifications with respect to systems and system groups 

are performed.

Errata   Here packages that are relevant to the user's systems are listed and 

can be managed.

Channels   Here all channels are managed.

Schedule   All scheduled actions are available here.

Users   Satellite user management.
