On Thursday, July 30, 2015, Red Hat will be presenting a free webinar for system administrators, engineers, and architects to learn what’s new with Red Hat Enterprise Linux.
During this webinar Red Hat curriculum manager and Red Hat Certified Architect, Michael Jarrett, will teach you about the new and changed features in Red Hat Enterprise Linux 7. He’ll focus on system administration topics that have changed significantly or are particularly important in Red Hat Enterprise Linux 7. He’ll also discuss the skills and expert knowledge needed to measure and influence performance on these systems.
Then Pete Hnath, director of curriculum, will show you how easy it is to train on Red Hat Enterprise Linux 7 and update your skills with the new Red Hat Learning Subscription, a year-long, all-access pass to more than 30 online learning courses.
With the release of Red Hat Enterprise Linux 6.7, we’re happy to also announce general availability of Red Hat Access Insights, a new hosted service from Red Hat designed to help customers proactively identify and resolve issues that could impact business operations.
Given the complexity and scale of modern IT environments, we recognize that it can be increasingly complicated to monitor, maintain, and secure enterprise infrastructure. By tapping into Red Hat’s collective experience

What are user namespaces? Sticking with the apartment complex analogy, the numbering of users and groups have historically been the same in every container and in the underlying host, just like public channel 10 is generally the same in every unit in an apartment building.
But, imagine that people in different apartments are getting their television signal from different cable and satellite companies. Channel 10 is now different for for each person. It might be sports for one person, and news for another.
Historically, in the Linux kernel, there was a single data structure which held users and groups. Starting in kernel version 3.8

The promise of Docker is that it simplifies application deployment, allows greater application density on hosts, and features a portable format that offers unparalleled flexibility over standard packaging. But one thing Docker doesn’t get you is the simplicity of `yum install foo` to install an application. Nor can Docker define or process a directed graph of container orchestration dependencies. We aim to change that.

Today, we are pleased to announced the general availability of Red Hat Directory Server 10, the latest version of Red Hat’s open source, network-based registry server. Built on the technologies delivered by the 389 Directory Server project, Red Hat Directory Server offers a Lightweight Directory Access Protocol (LDAP)-compliant server that centralizes critical application information, simplifies user management and enhances security across an entire organization.
As a tool for building business applications, Red Hat Directory Server provides

Two-factor authentication, or 2FA, is not something new. It has existed for quite some time and in different forms. What is a ‘factor’? A factor is something you have, something you know, or something you are. For example, if we combine a PIN that you know, with your fingerprint, we get a 2FA based on biometrics. In practice, biometric solutions are not often used because it’s not especially difficult to steal someone’s fingerprint (…and it is quite hard to revoke or replace your finger). The more practical approach to two-factor authentication is to combine something you know, a PIN or password, with something you have.
Something you have often comes in form of

Identity Management (IdM) in Red Hat Enterprise Linux includes an optional Certificate Authority (CA) component. This CA is the same CA included with the Red Hat Certificate System (RHCS). If they’re the same, what is the relationship between IdM and RHCS? Is there a secret plan to replace one with another? This post reviews some of the details associated with each of the offerings and explores different use cases – indicating where you might choose to use one solution over the other.

In the identity management server space Red Hat has two offerings: Identity Management (IdM) in Red Hat Enterprise Linux and Red Hat Directory Server (RHDS). This article is dedicated to helping you understand why there are two solutions and how to chose the best one for your environment.
Before diving in too deep

As many specialists in the security world know – the RSA Security Conference is one of the biggest security conferences in North America. This year it was once again held in San Francisco at the Moscone Center. Every year the conference gets bigger and bigger, bringing in more and more people and companies from all over the world.
If you attended – you may have noticed that Red Hat had a booth this year. Located in the corner of the main expo floor (not far from some of the “big guys” like: IBM, Microsoft, EMC, CA Technologies, and Oracle) we were in a great location – receiving no shortage of traffic. In fact, despite staffing the booth with six Red Hatters we didn’t have any “down time” – everyone seemed to be interested in what Red Hat has to offer in security.
Over the course of the conference I made a few interesting observations…

With every new Intel Xeon processor generation, the benefits typically span beyond simple increases in transistor counts or the number of cores within each processor. Things like increased memory capacity per chip or larger on-chip caches are tangible and measurable, and often have a direct effect on performance, resulting in record-breaking scores on various standard benchmarks.
There is, however, more to every new processor family launch than meets the eye. These new chips often send a ripple of innovation throughout our ecosystem of partners, forcing them to re-evaluate and re-visit existing performance results and break the status quo. The ability to support these partners is of paramount importance to Red Hat and, as a result, Red Hat Enterprise Linux is often being selected by our partners to support their ongoing benchmarking efforts.
Yesterday, Intel launched the Intel Xeon E7 v3 processor family with several new world record industry-standard benchmarks. Red Hat Enterprise Linux was used in nearly one-third of all results. The following table captures these leading results
