Red Hat Update Agent
The
Red Hat Update Agent
is your connection to Red Hat Network on Red Hat Enterprise Linux 4
It enables you to register 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 2, The
rhn_register
Client
for instructions, then return to this chapter for
Red
Hat Update Agent
instructions.
Important
You must use
Red Hat Update Agent
Version 2.5.4 or higher to upgrade your kernel
automatically. It installs the updated kernel and configures LILO or GRUB to boot the new

version, execute the command

installed, this command updates it.
