  • What's new in Red Hat Enterprise Linux 8.3? Enhanced container tools, more system roles and new cloud admin tools just for starters

    Red Hat Enterprise Linux (RHEL) 8.3 will be available in the coming weeks. In this post we'll take a look at some of the highlights and important new features that are planned for RHEL subscribers.

    A RHEL release has many constituencies. RHEL has to meet the needs of system administrators who crave system stability and predictability, and developers who want flexibility and new language and software choices. With new system roles, a major RHEL container tools update, cloud administration updates and more, RHEL 8.3 delivers for those who depend on enterprise open source to run today's businesses.

    The third update since RHEL 8's release in early 2019, RHEL 8.3 continues the six-month cadence of minor releases. By offering a predictable, time-based release cycle we help drive new features in a timely fashion without compromising the reliability of RHEL that our users and customers depend on.

  • Collect JDK Flight Recorder events at runtime with JMC Agent - Red Hat Developer

    JDK Flight Recorder, or JFR, is an event-based production environment profiler available from OpenJDK 8u272 forward. Being a HotSpot-native feature, JDK Flight Recorder performs with extremely low overhead in terms of how it uses both space and time.

    While JDK Flight Recorder collects basic Java runtime information by default, it is also possible to use JFR’s Event API to collect custom events. Developers who want to collect application-level events must actively define and instantiate them in their application source code.

    In this article, we’ll show you how to use JMC Agent and the JMC Agent Plugin to instrument your application classes with event-emitting code. When you use JMC Agent with the JDK Flight Recorder Event API, you do not need to shut down the JVM and recompile the application code.

  • New custom metrics and air gapped installation in Red Hat 3scale API Management 2.9 - Red Hat Developer

    We continue to update the Red Hat Integration product portfolio to provide a better operational and development experience for modern cloud– and container-native applications.

Among other features, we have updated the 3scale API Management and Gateway Operators.

    This article introduces the Red Hat 3scale API Management 2.9 release highlights, including air-gapped installation for 3scale on Red Hat OpenShift and new APIcast policies for custom metrics and upstream mutual Transport Layer Security (TLS).

RHEL 8.3 updates target digital transformation

  • RHEL 8.3 updates target digital transformation

    With an eye toward easing digital transformation projects, the latest version of Red Hat Enterprise Linux includes improved container tools, new security profiles and the addition of several System Roles, including ones for kernel settings, SAP HANA and NetWeaver.

    Red Hat also improved RHEL performance, adding updates to Tuned, which is a set of pre-configured profiles. Tuned allows IT shops to take better advantage of Red Hat's multi-architecture, enabling software to run faster across a number of different hardware architectures. Also, Red Hat Insights continues to remain available by default for RHEL systems. As part of version 8.3, Red Hat added administrator views specifically for SAP HANA deployments.

    System Roles makes both common and complex RHEL configurations more consistent and accessible to a wider range of IT skillsets in large organizations.

Red Hat Enterprise Linux (RHEL) 8.3

    Exactly three months after the beta release of Red Hat Enterprise Linux (RHEL) 8.3, the Red Hat team has now announced a new stable version of the RHEL 8 platform called RHEL 8.3.

    The latest stable release aims to deliver more stability with cloud-native innovation by introducing new security profiles, enhanced performance capabilities, and updated container tools.

RHEL 8.3 Released With TSX Disabled By Default

  • RHEL 8.3 Released With TSX Disabled By Default To Avoid Mitigation Overhead

    Red Hat Enterprise Linux 8.3 is out today as the latest release of the RHEL8 platform.

    The latest stable release of Red Hat Enterprise Linux 8, RHEL 8.3, is focused on expanded Red Hat System Roles support, updates to Tuned, new SCAP profiles, updated Application Streams, and other enterprise-minded stability enhancements. Some specific changes to note with Red Hat Enterprise Linux 8.3 include:

    - RHEL 8.3 is now disabling Intel Transactional Synchronization Extensions (TSX) by default. Disabling of TSX by default is done in the name of security and to remove the performance penalty of having TSX Asynchronous Abort mitigations for Xeon Cascade Lake processors. TSX can be enabled with the "tsx=on" kernel parameter.

    - New module streams for Ruby 2.7, Nginx 1.18, Perl 5.30, and Node.js 14. The streams for Python 3.8, PHP 7.4, and HTTPD 2.4.

Identical in most respects to 8.2, the new version adds pre-packaged configuration, compliance and container options to ease the daily toil of devops in the modern IT environment.

    There are new Red Hat System Roles, which guide and automate OS configurations to speed installation by what RH charitably describes as those with ‘a wider range of skill sets’. New roles now include kernel settings, log settings, SAP HANA, SAP NetWeaver and management.Tuned, a set of pre-configured, architecture-aware performance profiles, has also been updated.

  • Capturing Decrypted TLS Traffic with Arkime - NETRESEC Blog

    The latest version of Arkime (The Sniffer Formerly Known As Moloch) can now be fed with a real-time stream of decrypted HTTPS traffic from PolarProxy. All that is needed to enable this feature is to include "pcapReadMethod=pcap-over-ip-server" in Arkime's config.ini file and start PolarProxy with the "--pcapoveripconnect 127.0.0.1:57012" option. PolarProxy will then connect to Arkime's PCAP-over-IP listener on TCP port 57012 and send it a copy of all TLS packets it decrypts.

Making the Switch to elementary OS

It all started with an upgrade. In October, 2020 version 20.10 of Ubuntu came out. As I usually do, I duly clicked the button to start the process. That upgrade seemed to go smoothly — everything installed quickly with no conflicts or error messages. I walked away to make a cup of white tea, and when I came back the installation had finished and my laptop rebooted. It was then that I noticed a problem. A fairly big one. Instead of a login screen, I saw a field of aubergine (the colour, not the vegetable). I thought that my laptop was sleeping, so I pressed some keys to try to wake it up. It didn't work. I rebooted, but I was faced with the same problem. Read more
