To ensure that the GPG keys are installed, run: $ rpm -q gpg-pubkey The command should return the strings below: gpg-pubkey-fd431d51-4ae0493b gpg-pubkey-2fa658e0-45700c69 If the Red Hat GPG Keys are not installed, this is a finding.

To ensure the system can cryptographically verify base software packages come from Red Hat (and to connect to the Red Hat Network to receive them), the Red Hat GPG keys must be installed properly. To install the Red Hat GPG keys, run: # rhn_register If the system is not connected to the Internet or an RHN Satellite, then install the Red Hat GPG keys from trusted media such as the Red Hat installation CD-ROM or DVD. Assuming the disc is mounted in "/media/cdrom", use the following command as the root user to import them into the keyring: # rpm --import /media/cdrom/RPM-GPG-KEY

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
