Red Hat Update Agent
The
Red Hat Update Agent
is your connection to Red Hat Network. It enables you to reg-
ister your systems, create System Profiles, and alter the settings by which your organization
and RHN interact. Once registered, your systems can use the
Red Hat Update Agent
to
retrieve the latest software packages from Red Hat. This tool allows you to always have
the most up-to-date Red Hat Enterprise Linux systems with all security updates, bug fixes,
and software package enhancements.
Remember, this tool must be run on the system you wish to update. You cannot use the
Red Hat Update Agent
on the system if it is not entitled to an RHN service offering.
Warning
Only systems running Red Hat Enterprise Linux 3 and later can use the
Red Hat Update
Agent
to register with RHN. Systems running Red Hat Enterprise Linux 2.1 must use
Red Hat Network Registration Client
before starting the
Red Hat Update Agent
. Refer
to Chapter 5
Red Hat Network Registration Client
for instructions, then return to this
chapter for
Red Hat Update Agent
