You can update your Red Hat Linux system at anytime, adding new applications or
enhancements to packages you already have installed. Installing new software
files, or RPMs, is simple. This chapter explains three ways you can update
your system: by using Red Hat Network, by going to http://www.redhat.com/apps/support/updates.html and checking the errata
list, and by getting packages from the installation CD that you did not
initially install.
Red Hat Network gives you two ways to update your system: the Web interface, known as
Software Manager and
Red Hat Update Agent. Software Manager is an online tool that
lets you manage up to five systems at once. Red Hat Update Agent is a standalone tool
that manages one system only.
Updating from the errata list involves going to the Red Hat website, looking through the
latest errata list, and downloading and installing the errata you
want. Installing additional packages from the installation CD involves
selection and installation from the GUI that appears on your desktop after
you insert the CD in your CD-ROM drive.
