Is using Red Hat site for documentation legal?
If I understand correctly you have to be a customer of Red Hat to be allowed to use their bandwidth:
“2. Terms Applicable to Red Hat Content. In order to access a Red Hat Portal and Red Hat Content, you must be a current Customer of Red Hat or its affiliates
6. Use of Content. Red Hat grants you a personal, non-assignable license to use Red Hat Content for your own internal use while you are a Red Hat Customer (as defined in Section 2 above). Distributing any portion of Red Hat Content to a third party, using any Red Hat Content for the benefit of a third party, or using Red Hat Content in connection with software other than Red Hat Software under an active Red Hat subscription are all prohibited. Red Hat authorizes you to display on your computer, download, play, and print the Red Hat Content provided: (a) the copyright notice is not removed, (b) Red Hat Content is not be altered, (c) Red Hat Content is used only for your personal, educational, and non-commercial use in support of your active valid subscriptions to Red Hat products and services and in accordance with your Customer Agreement, (d) you do not further redistribute or copy Red Hat Content, and (e) you comply with any Additional Terms. In the event of a conflict, inconsistency, or difference between this Section 6 and the terms of a License or Customer Agreement, the License or Customer Agreement will control
(for example, for Red Hat Content licensed under a Creative Commons License, you will have the rights set forth in the applicable Creative Commons License).”
