New Subscription Management for RHEL

28 Mart 2011 11:56 AM - Duyuru / omer.sen

With RHEL 5.7 and 6.1 Red Hat has changed the way that it manages subscription on RHN site. As Endersys we wanted to inform you about this

Background

When you make a purchase from Red Hat, you are buying a subscription. A subscription gives you the right to access particular Red Hat services for a period of time on one computer. Once it is applied to a computer, the “right” becomes an “entitlement”. The services you receive include easy access to Red Hat’s software downloads, security and errata updates, access to knowledge resources such as in-depth technical papers, videos and knowledgebase articles, and access to a certain level of technical support — all through our Customer Portal.

You need one subscription for each computer you expect to use Red Hat software or services on. To designate which computer you plan to access Red Hat services from, you must first register that computer, and then you must assign an subscription to that computer directly — a process called Entitling. During the Entitlement process, an Entitlement Certificate is created on your computer. When you download software to your computer from the Red Hat Content Delivery Network, the Entitlement Certificate authenticates and authorizes the computer to receive the requested software services.

Changes to Subscription Management

Prior to this change, Red Hat has used a “pool model” for counting subscriptions, in which we track the total number of subscriptions a customer has purchased, the total number of the customer’s systems that are using subscriptions, and the difference between the two numbers. This model, which will now be called RHN Classic Subscription Management, is simple and effective, but has limitations, including an inability to link a specific subscription with a specific system.

As our product range expands, we’ve needed to change the way we track the subscriptions that our customers purchase and use. Our new model, called RHN Certificate-Based Subscription Management, keeps track of specific subscriptions assigned to specific computers using x.509 certificates.

Collaboration and Online Groups at Red Hat

22 Mart 2011 11:32 PM - Duyuru and Red Hat / omer.sen

Red Hat added collaboration functionality to access.redhat.com with Online User Groups. Subscription customers will be able to interact directly with other Red Hat users to share content and build knowledge. The Online User Groups will create a forum for customers and partners to:

* Post directly to user forums
* Benefit from direct access to more industry experts
* Access and rate user-generated content

With collaboration and communities being the DNA of Red Hat, this project will be an important addition to our knowledge repository.
