Web interface. The communication with the clients is performed through the 

up2date

 application and several daemons running on the client.

Concepts

In this section we describe some of the concepts used in the RHN/satellite 

server. These concepts include:

System

System group

System set

Entitlement

Channel

Errata

Action

Activation key

We describe each of these concepts in some detail in the satellite server context. 

Some of these same terms exist as a concept in ZENworks as well, but might 

have a slightly different meaning.

System

A system can be any Red Hat Linux installed machine with 

up2date

 configured 

and connected to the satellite server. The connection to the satellite server is 

done using a user ID. This user ID is created in the satellite server and is the 

initial administrator for the new system.

System group

A system group is an entity in the satellite server that can contain systems. When 

created, the container is empty. Systems can be added to the system group. The 

system group is used in the satellite server to perform actions for multiple 

systems (the ones in the group) simultaneously.

System set

Where the system group is more or less fixed, the system set can be used to 

construct a selection of systems to perform an action on. These systems can be 

picked individually or on a group level or based on some property of the system.
