From There to Here (But Not Back Again)

Red Hat

Red Hat Product Security recently celebrated our 15th anniversary this summer and while I cannot claim to have been with Red Hat for that long (although I’m coming up on 8 years myself), I’ve watched the changes from the “0day” of the Red Hat Security Response Team to today. In fact, our SRT was the basis for the security team that Mandrakesoft started back in the day.

In 1999, I started working for Mandrakesoft, primarily as a packager/maintainer. The offer came, I suspect, because of the amount of time I spent volunteering to maintain packages in the distribution. I also was writing articles for TechRepublic at the time, so I also ended up being responsible for some areas of documentation, contributing to the manual we shipped with every boxed set we sold (remember when you bought these things off the shelf?).

What is the GRUB2 boot loader?

Filed under
Red Hat

There are various things that make up an operating system. In any operating system, one of the most critical parts is powering on the machine. During this process, the computer will execute a small program in read-only memory (ROM) to begin initiating the startup process. This small program is known by many names, but most often called a boot loader. In almost every Linux distribution, including Fedora, GRUB2 (or GRand Unified Bootloader 2) is the default boot loader. Even though it is a critical piece of the operating system, many people aren’t aware of the boot loader, all that goes into it, or how it can be customized.

  • Rivals Red Hat, Mirantis Announce New OpenStack Partnerships

    The cloud rivals both announce new telco alliances as competition in the cloud market heats up.
    Red Hat and Mirantis both announced large agreements this week that bring their respective OpenStack technologies to carrier partners. The news comes ahead of the OpenStack Summit that kicks off in Barcelona, Spain, on Oct. 24.

    Red Hat announced on Oct. 19 that it has a new OpenStack partnership with telco provider Ericsson.

    "Ericsson and Red Hat recognize that we share a common belief in using open source to transform the telecommunications industry, and we are collaborating to bring more open solutions, from OpenStack-based clouds to software-defined networking and infrastructure, to customers," Radhesh Balakrishnan, general manager of OpenStack at Red Hat, told eWEEK.

    In this presentation I will introduce Flatpak and how it changes the software distribution model for Linux. In short it will explain the negatives of using packages, how Flatpak solves this, and how to create your own applications and distribute them for use with Flatpak. This presentation was given at the GNOME 3.22 release party, organized by the Beijing GNOME User Group.

  • The who in the where?

    The job is like many other roles called “Community Manager” or “Community Lead.” That means there is a focus on metrics and experiences. One role is to try ensure smooth forward movement of the project towards its goals. Another role is to serve as a source of information and motivation. Another role is as a liaison between the project and significant downstream and sponsoring organizations.

    In Fedora, this means I help the Fedora Project Leader. I try to be the yen to his yang, the zig to his zag, or the right hand to his right elbow. In all seriousness, it means that I work on a lot of the non-engineering focused areas of the Fedora Project. While Matthew has responsibility for the project as a whole I try to think about users and contributors and be mechanics of keeping the project running smoothly.

  • Red Hat – the open source conglomerate

    As successful companies grow, they accumulate products; new ones are developed and additional ones are acquired. Managing diverse portfolios is a challenge, not least when it comes to putting it all together on a single presentation slide to make it appear there is an overall coherent product strategy.

  • Ericsson Embraces Red Hat OpenStack Platform

    Ericsson and Red Hat today announced a broad alliance to work together on network functions virtualization (NFV) products. And the telco infrastructure provider will now support the Red Hat OpenStack Platform.

    Ericsson already has a longstanding distribution partnership with Red Hat that includes Red Hat Enterprise Linux and Red Hat JBoss Middleware. The existing distribution partnerships define not only commercial terms, but also joint support models, co-engineering and certification testing, and joint go-to-market collaboration.

  • keepalived: Simple HA

    We have been using keepalived in Fedora Infrastructure for a while now. It’s a pretty easy to use and simple way to do some basic HA. Keepalived can keep track of which machine is “master” for a IP address and quickly fail over and back when moving that IP address around. You can also run scripts on state change. Keepalived uses VRRP and handles updating arp tables when IP addresses move around. It also supports weighting so you can prefer one or another server to “normally” have the master IP/scripts.

  • What does Factory 2.0 mean for Modularity?

    This blog now has a drop-down category called Modularity. But, many arteries of Modularity lead into a project called Factory 2.0. These two are, in fact, pretty much inseparable. In this post, we’ll talk about the 5 problems that need to be solved before Modularity can really live.

    The origins of Factory 2.0 go back a few years, when Matthew Miller started the conversation at Flock. The first suggested names were “Fedora Rings”, “Envs and Stacks”, and Alephs.

  • varnish-5.0, varnish-modules-0.9.2 and hitch-1.4.1, packages for Fedora and EPEL

    The Varnish Cache project recently released varnish-5.0, and Varnish Software released hitch-1.4.1. I have wrapped packages for Fedora and EPEL.

    varnish-5.0 has configuration changes, so the updated package has been pushed to rawhide, but will not replace the ones currently in EPEL nor in Fedora stable. Those who need varnish-5.0 for EPEL may use my COPR repos at They include the varnish-5.0 and matching varnish-modules packages, and are compatible with EPEL 5, 6, and 7.

Linux users urged to protect against 'Dirty COW' security flaw

Filed under
Red Hat

Organisations and individuals have been urged to patch Linux servers immediately or risk falling victim to exploits for a Linux kernel security flaw dubbed ‘Dirty COW'.

This follows a warning from open source software vendor Red Hat that the flaw is being exploited in the wild.

Phil Oester, the Linux security researcher who uncovered the flaw, explained to V3 that the exploit is easy to execute and will almost certainly become more widely used.

"The exploit in the wild is trivial to execute, never fails and has probably been around for years - the version I obtained was compiled with gcc 4.8," he said.

  • The Point Of Docker Is More Than Containers
    Spending time with Docker during Cloud Field Day about a month ago opened my eyes to the larger ecosystem that Docker is building, and that others are building around it. There is so much more to Docker than just the idea of immutable containers. For a start, Docker made using containers easy. That’s no small feat for a tricky piece of technical infrastructure. Making it easy, and specifically easy for developers, to use removed a lot of friction that was no small contributor to the pain of other, earlier methods. It gave developers are really simple way to create a fully functional development environment, isolated from all other dependencies, with which to work.
  • What are the Top NFV Risks for Carriers?
    What are the risks of network functions virtualization (NFV)? As with any emerging technology, moving fast or picking the wrong components can do more harm than good. Let’s spend some time breaking down the NFV risks in building a virtual network. I have spent the few months gathering feedback from various service providers to get their view on whether NFV and its cousin software-defined networking (SDN) are ready for prime time. Even though many service providers expressed optimism that NFV technology is moving toward maturity, there are definitely cautionary tales on what to look out for. This article serves as an introduction to the challenges of NFV component selection – later articles will refer in more detail to the challenges in selecting NFV hardware and software components such as OpenStack and Open vSwitch.

  • TNS Guide to Serverless Technologies: The Best Frameworks, Platforms and Tools
    Even if you don’t need the servers themselves, serverless technologies could still require plenty of supporting software. Frameworks are needed to codify best practices, so that everyone is not out to reinvent the wheel, especially when it comes to interfacing with various languages such as Go, JavaScript and Python. And platforms are needed to help people avoid spending too much time on configuring the underlying infrastructure, perhaps by handing the work off to a service provider. Just in time for the Serverless conference in London, this post highlights some of the most widely used frameworks and platforms, as well as other supporting tools, that make successful serverless-based workloads happen.

  • Why Is The Penguin Tux Official Mascot of Linux? Because Torvalds Had Penguinitis!
    The official mascot of the Linux kernel developed by Linus Torvalds is a penguin named Tux. You might have thought about the probable reasons why a penguin has been used as the face of the Linux kernel. Some people believe that Torvalds was bitten by a penguin that’s why he chose one to represent his kernel.
  • SafeEyes – An Useful Linux Utility That Prevents Eye Strain
    Working in Computer for long hours is pain, and it will definitely affect your eyes. You must take some breaks for your eyes at regular intervals. There are numerous utilities available out there to remind you to take breaks. The one we are going to discuss now is SafeEyes. It is a free and open Source Linux alternative for EyeLeo, a MS Windows-only app. As the name suggests, SafeEyes will protect you from Eye Strain by reminding or forcing you to take breaks after a particular period of time. During the break, it will suggest you some simple exercises like walking for a while, rolling your eyes etc., to relax yourself. If you are a hardcore user who work on computers for long hours, I recommended you to use SafeEyes in your system.

  • Spotify for Linux – In the friendzone
    Spotify is arguably the most popular music streaming service out there. Apologies to any diehard fanboys who may have been offended by this statement. With 100 million users and tight social media integration, it sure plays in the big league. You can also go premium and this will render your interface ad-free and fidelity-high. But what about Linux? As it turns out, Linux has never been high on the list of priorities for the Spotify team, and at some point, the support was discontinued, then it was revived recently, which prompted me to give it a try. Seeking originality and uniqueness in my work, I opted for Fedora, only to learn that only builds for Debian-based distributions are available. In other words, Ubuntu and friends. Very similar to my experience with Sayonara. Anyhow, let’s see what gives.
