Red Hat Update Agent
The
Red Hat Update Agent
is your connection to the Red Hat Network. 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 will allow you to always have the most up-to-date Red Hat
Linux systems with all security patches, 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 Linux 8.0 can use the Red Hat Update Agent to register with RHN.
Systems running Red Hat Linux 6.2 through 7.3 and Advanced Server will need to use the separate
Red Hat Network Registration Client before starting the Red Hat Update Agent . Refer to Chapter
7 for instructions. Then return to this chapter for instructions on using the Red Hat Update Agent .
Important
You must use Red Hat Update Agent Version 2.5.4 or higher to upgrade your kernel automatically.
It will install the updated kernel and configure LILO or GRUB to boot the new kernel the next time

up2date
. If you do not have the latest version installed, this command will update it.
