6. Solution:
Before applying this update, make sure all previously released errata relevant to your system have been applied.
To update all RPMs for your particular architecture, run:
rpm -Fvh [filenames]
where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs.
Please note that this update is also available via Red Hat Network. Many people find this an easier way to apply updates. To use Red Hat Network, launch the Red Hat Update Agent with the following command:
up2date
This will start an interactive process that will result in the appropriate RPMs being upgraded on your system.
7. Verification:
MD5 sum Package Name

These packages are GPG signed by Red Hat, Inc. for security. Our key is available at:
http://www.redhat.com/about/contact.html
You can verify each package with the following command: rpm --checksig filename
If you only wish to verify that each package has not been corrupted or tampered with,
examine only the md5sum with the following command: rpm --checksig --nogpg filename
Note that you need RPM >= 3.0 to check GnuPG keys.
