Raspberry Pi: Hands-on with Kali, openSUSE, Fedora and Ubuntu MATE Linux

Filed under
Linux
Red Hat
SUSE
Ubuntu

It has been nearly two years since I tried Fedora, Manjaro and Ubuntu MATE on the Raspberry Pi 2 & 3, and there have been a lot of changes since then. Most for the better, such as the introduction of the Pi 3B+, but a few for the worse, such as the end of the Manjaro Pi development. So I think it's time to take a fresh look at this.

But, first, why would anyone even want to do this, when Raspbian Linux is available, free, and supports all the special features, quirks and capabilities of the Raspberry Pi hardware?

Well; the most common reasons seem to be that users want to work with a "familiar" distribution, meaning one that they are already using on a PC, such as Ubuntu. Another common reason is that companies have "standardized" on a specific version of Linux for servers, desktops and laptops; this is frequently the case with SUSE and Fedora, for example. Yet another reason might be a specific use of the Raspberry Pi; for example, Kali Linux for penetration testing. Finally you might just be curious (or masochistic) like me, and want to see how (or if) all of this works together.

The D in Systemd stands for 'Dammmmit!' A nasty DHCPv6 packet can pwn a vulnerable Linux box

Filed under
Red Hat
Security
Web

A security bug in Systemd can be exploited over the network to, at best, potentially crash a vulnerable Linux machine, or, at worst, execute malicious code on the box.

The flaw therefore puts Systemd-powered Linux computers – specifically those using systemd-networkd – at risk of remote hijacking: maliciously crafted DHCPv6 packets can try to exploit the programming cockup and arbitrarily change parts of memory in vulnerable systems, leading to potential code execution. This code could install malware, spyware, and other nasties, if successful.

The vulnerability – which was made public this week – sits within the written-from-scratch DHCPv6 client of the open-source Systemd management suite, which is built into various flavors of Linux.

Fedora and Red Hat: Fedora 29 Next Week, PHP Builds, and Red Hat's Ramblings

Filed under
Red Hat
  • Fedora 29 Is Cleared For Release Next Tuesday

    After it was delayed last week, the beautiful Fedora 29 will greet the world next week. 

    Fedora 29 has ended up being another great release that's running well and looking great from the Fedora Workstation perspective. It's also exciting on the Fedora Silverblue front for replacing what was Atomic Workstation. There's also new features on the server front too. All around, there's plenty of new features in Fedora 29.

  • PHP version 7.1.24RC1 and 7.2.12RC1

    Release Candidate versions are available in remi-test repository for Fedora and Enterprise Linux (RHEL / CentOS) to allow more people to test them. They are available as Software Collections, for a parallel installation, perfect solution for such tests (for x86_64 only), and also as base packages.

  • Knative: Configuration, Routes and Revisions

    In Part-1 of this series, you were introduced on how deploy your first serverless service using Knative Serving and in Part-2 you were able to understand how to build the serverless services using Knative Build.

  • This is not the root cause you're looking for

    The IT industry is going through a paradigm shift from monolithic to microservices systems. Microservices provide a huge benefit allowing rapid software development and decreasing time to market (TTM), but it also requires a shift in processes and mindsets as we have seen. Adapting to microservices’ needs is crucial and delaying your adaptation will just increase your technical debt, and if there is one thing we have learned throughout past years is, technical debt finds a way to be repaid, but with interest.

  • Welcome Apache Kafka to the Kubernetes Era!

    We have pretty exciting news this week as Red Hat is announcing the General Availability of their Apache Kafka Kubernetes operator. Red Hat AMQ Streams delivers the mechanisms for managing Apache Kafka on top of OpenShift, our enterprise distribution for Kubernetes.

    Everything started last May 2018 when David Ingham (@dingha) unveiled the Developer Preview as new addition to the Red Hat AMQ offering. Red Hat AMQ Streams focuses on running Apache Kafka on OpenShift. In the microservices world, where several components need to rely on a high throughput communication mechanism, Apache Kafka has made a name for itself for being a leading real-time, distributed messaging platform for building data pipelines and streaming applications.

    A leader in the traditional infrastructure deployments, Apache Kafka was missing pieces to be a easily usable container-native citizen in the new Kubernetes era. As a result, a team grouped in 2017 to create the upstream Strimzi project. This team worked to apply the new operator pattern to solve the gaps. With the development of new components deployed along the traditional Apache Kafka broker, these new Kubernetes operators are now able to manage cluster wide resources as well as entities as topics and authentication users.

  • GCC 8 and tools now in beta for Red Hat Enterprise Linux 6 and 7

    We are pleased to announce the immediate availability of Red Hat Developer Toolset 8 beta for Red Hat Enterprise Linux 6 and 7.  

  • How Red Hat is addressing the digital woes of APAC’s financial services sector

    Several financial institutions across the Asia Pacific have adopted Red Hat hybrid cloud architectures and practices, in a concerted effort to become more agile while reducing costs and more effectively managing risks.
    The regional banks that have adopted the open source vendor’s technology include Malaysia’s AmBank Group, Indonesia’s PT Bank Tabungan Pensiunan Nasional Tbk, Indonesia’s Bank BRI, China’s China Merchants Bank, Taiwan’s Cathay United Bank, and Japan’s Fukuoka Financial Group.

  • Red Hat, NVIDIA regulate on open source offerings to accelerate emerging workloads like artificial intelligence

    Red Hat announced on Tuesday that it is collaborating with NVIDIA to bring a new wave of open innovation around emerging workloads like artificial intelligence (AI), deep learning and data science to enterprise data centers around the world.

    Driving this effort is the certification of enterprise Linux platform, Red Hat Enterprise Linux, on NVIDIA DGX-1 systems. This certification provides a foundation for the rest of the Red Hat portfolio, including Red Hat OpenShift Container Platform, to be deployed and jointly supported on NVIDIA’s AI supercomputers.

    As NVIDIA DGX-1 systems enter the datacenter to provide powerful AI platforms, IT teams will often want to manage and maintain these systems within their existing operations, which frequently are Red Hat Enterprise Linux-based.

  • Red Hat Certifies Linux for NVIDIA AI Boxes

    Red Hat cozied up even further with NVIDIA yesterday, certifying its Enterprise Linux platform on the GPU vendor’s DGX-1 machine learning boxes.

    The announcement makes it easier for enterprises to manage their machine learning training on their own premises, the Linux vendor said.

    Under the deal, existing Red Hat Enterprise Linux subscriptions are eligible for use on DGX-1 systems. It also opens up certified applications developed for Red Hat’s Linux system to DGX-1 users. Red Hat is going beyond certification by optimizing its Linux for DGX-1 using tuned profiles for the NVIDIA platform. This draws on the tuned package that it released in Red Hat Enterprise Linux 6. The company has said in the past that tuned profiles can boost performance in the double-digit percent range.

  • Fedora Magazine: 4 cool new projects to try in COPR for October 2018

    COPR is a collection of personal repositories for software that isn’t carried in the standard Fedora repositories. Some software doesn’t conform to standards that allow easy packaging. Or it may not meet other Fedora standards, despite being free and open source. COPR can offer these projects outside the standard set of Fedora Fedora packages. Software in COPR isn’t supported by Fedora infrastructure or signed by the project. However, it can be a neat way to try new or experimental software.

  • Thunderbolt ports & bolt update

    Not every USB-C port is a Thunderbolt 3 port. Watch out for the logos!

    [...]

    In related news: bolt 0.5 is out (since about a month now) and will be shipped with Fedora 29. Have a look at the release notes for a complete list of changes, but the most important one I want to highlight here is the new force power D-Bus API. What is it and why do we need it? The Thunderbolt controller can be in two different modes: one in which it is constantly powered (native enumeration mode) and one in which it is controlled by the BIOS. In the latter mode, if nothing is plugged into the Thunderbolt port the controller is completely powered down and it looks as if there is no Thunderbolt hardware present at all. This is great because it saves battery, but there are two problems: 1) boltd wants to know what security level the Thunderbolt controller is in, and more importantly 2) the firmware update daemon (fwupd) wants to know the firmware version of the Thunderbolt controller, so that it can check if there are updates available (and if so, show them in GNOME Software). Luckily, newer kernel versions have (on supported platforms) a sysfs interface that can be used to "force-power" the Thunderbolt controller. Both boltd and fwupd have support for that, which is great, but also the root of a race: the force-power interface is not reference counted and also write only (you cannot ask for the current status). Now if boltd force-powers the controller, uevents will be generated which, in turn, will be processed by fwupd and it will try to read the firmware version. If, in the meantime, boltd is done with its thing and powers the controller down again but fwupd is not yet done reading the firmware, then that read will fail. Or the other way around: fwupd powers the controller, boltd gets started due to the uevents, but meanwhile fwupd is powering the controller down again, boltd might e.g. hang reading the boot-acl.

Fedora Toolbox ready for testing!

Red Hat

As many of you know we kicked of a ambitious goal to revamp the Linux desktop when we launched Fedora Workstation 4 years. We wanted to remove many of the barriers to adoption of Linux as a desktop and make it a better operating system for all, especially for developers.

To that effect we have been pushing a long range of initiatives over the last 4 years ago, ranging from providing a better input stack through libinput, a better display system through Wayland, a better audio and video subsystem through PipeWire, a better way of doing application packaging and dependency handling through Flatpak, a better application installation history through GNOME Software, actual firmware handling for Linux through Linux Vendor Firmware Service, better manageability through Fleet Commander, and Project Silverblue for reliable OS updates. We also had a lot of efforts done to improve general hardware handling, be that work on glvnd and friends for dealing with NVidia driver, the Bolt project for handling Thunderbolt devices better, HiDPI support in the desktop, better touch support in the desktop, improved laptop battery life, and ongoing work to improve state of fingerprint readers under Linux and to provide a flicker free boot experience.

Mozilla: Firefox, Reps, Encryption and Testday Results

  • Firefox Ups the Ante with Latest Test Pilot Experiment: Price Wise and Email Tabs
    Over the last few years, the Test Pilot team has developed innovative features for Firefox desktop and mobile, collaborating directly with Firefox users to improve the browser – from reminders to return to a tab on your desktop to a simple and secure way to keep track of your passwords. Today, just in time for the holiday shopping season, the Firefox Test Pilot team is introducing Price Wise and Email Tabs — the latest experimental features designed to give users more choice and transparency when shopping online. These game-changing desktop tools are sure to make shopping a breeze with more options to save, share, track and shop. We’ve also made a few updates to the Test Pilot program itself to make it even easier to become a part of the growing Firefox users testing new features.
  • Let Price Wise track prices for you this holiday shopping season
    The online shopping experience is really geared towards purchases that are made immediately. Countless hours have been spent to get you checked out as soon as possible. If you know what you want, and you’re happy with the price, this is great. On the other hand, sometimes you want to take your time, and wait for a deal. For those times, we have our new Test Pilot experiment, Price Wise.
  • Sharing links via email just got easier thanks to Email Tabs
    If your family is anything like ours, the moment the calendar flips to October, you’re getting texts and emails asking for holiday wish lists. Email remains one of the top ways people save and share online, so you likely do what we do: help make everyone’s life easier by diligently copy and pasting the URLs, titles and descriptions into a list. What if Firefox could make that process easier? Thanks to our new Test Pilot experiment Email Tabs, it can.

  • As far as I'm concerned, email signing/encryption is dead
    A while back, I used to communicate a lot with users of my popular open source project. So it made sense to sign emails and let people verify — it’s really me writing. It also gave people a way to encrypt their communication with me. The decision in favor of S/MIME rather than PGP wasn’t because of any technical advantage. The support for S/MIME is simply built into many email clients by default, so the chances that the other side would be able to recognize the signature were higher.
  • Firefox 64 Beta 8 Testday Results

Latest Games for GNU/Linux

  • Little Misfortune is a sweet looking adventure, should hopefully get Linux support
    From the same developer who made Fran Bow (which supports Linux), Little Misfortune is what they're calling an interactive story. With a focus on exploration and the characters, including sweet and dark elements with choices that have consequences. With that in mind, when I spoke to the developer in regards to a Linux build they said "We will try to have it, yes! :)". Not solid, but a very positive response especially since they've supported Linux before.
  • Luna and the Moonling is a sweet puzzle game that's now available on Linux
    Luna and the Moonling from Greyborn Studios is a colourful puzzle game with an aim to put a new spin on block-pushing puzzle gameplay. Note: Key provided by the developer. For those who aren't aware, some of the people from Greyborn Studios previously worked on some pretty major titles like System Shock 2, Thief, Skylanders, Red Faction and quite a few more. "From the moment we released in early access last year we’ve had requests from Linux gamers to support the platform," said Michael Ryan, CTO & Technical Director of Greyborn Studios. "We’re big fans of the platform ourselves and were happy to oblige. We really hope Linux users enjoy the game, and welcome them to the Greyborn community," Ryan said.
  • Odd Realm is a sandbox settlement builder inspired by Dwarf Fortress and Rimworld with Linux support
  • Valve gave out more details about Artifact, including some public APIs and pre-order is up
    Artifact, the multi-lane card game from Valve is closing in on release and so Valve have given out a bunch of new details on what to expect. Firstly, it's now up for pre-order on Steam for £15.99/$20 and for that price you will get 10 card packs, 5 event tickets, and two complete starter decks. Considering how much such packs cost for real-life card games, that price is actually quite reasonable I think. Additional packs of cards will be $1.99, each pack has 12 random cards. You will also be able to buy and sell cards on the Steam Market.
  • Zeon 25, a retro-inspired hardcore shoot 'em up is now in Early Access
    The Doom-inspired UI bar along the bottom looked quite amusing, haven't really seen many games do something like that in recent years. Looks like it could be worth a shot, the action looks intense enough to keep me interested for sure. While it's in Early Access, they're hoping to add a co-op mode along with new maps, new enemies, new levels and so on. The full release is currently scheduled for Q1 2019 although that may change depending on how much feedback they get during development.
  • Neuroslicers is a narrative driven, online competitive cyberpunk RTS that will have Linux support
    Neuroslicers from developer Dream Harvest seems like a very interesting title. A narrative driven, online competitive cyberpunk RTS and it will be coming to Linux.
  • Feral Interactive have put out the system requirements for Total War: WARHAMMER II, due on Linux this month
    Ready your swords and your axe as Total War: WARHAMMER II is heading to Linux this month and Feral Interactive have now put up the system requirements.
  • Here's What You Need to Play Total War: WARHAMMER II on Linux and macOS
    UK based video games publisher Feral Interactive revealed today the official system requirements of the Total War: WARHAMMER II video game for Linux and Mac systems. In mid-June, Feral Interactive teased Linux and Mac gamers with the upcoming release of the Total War: WARHAMMER II port for their beloved platforms, the sequel to the critically acclaimed Total War: WARHAMMER video game released more than two years ago. The company said that the Linux and macOS port is coming in November. Well, November is here, and now Feral Interactive has revealed the official system requirements for playing the Total War: WARHAMMER II video game on Linux and macOS-powered computers, saying that the port will be available on these two platforms later this month.
  • Warhammer: Vermintide 2 ‘Back to Ubersreik’ DLC Remasters Three Maps From The First Game
    Warhammer: Vermintide 2, Fatshark’s first person rat-murdering action game, will be getting another DLC next month. The Back to Ubersreik DLC takes players to the setting of the first Vermintide game, and will feature remasters of three maps seen in the original Vermintide.
  • Dungeon crawler Ebony Spire: Heresy has a rather nice Anniversary Update that's worth a look
    After managing to sell a few thousand copies, the dungeon crawler Ebony Spire: Heresy has a great update now available. For those who missed the story, the developer Bearded Giant Games initially failed to really get anywhere with the game. They wrote a post on Gamasutra about it, where they said it had been a "a soul crushing experience". A pretty sobering reading, as game development has become so much harder in the past few years with stores being flooded with new games. Anyway, many months later they managed to hit over 6,000 sales and so this update is a thank you for keeping the developer going.

IBM/Red Hat: Moving, Supercomputing and How IBM and Red Hat Will Impact Your Cloud Strategy

  • Moving house and moving applications are not the same. Or are they?
    As a Solution Architect I see my job as many things, from supporting customers in adopting Red Hat technology, educating organisations about using open source technologies and the benefits it brings, to thinking of ways to solve business challenges using technology and culture change. However, these are all generally in the space of “green field” app development. But what about all the systems keeping the business going today? The challenges businesses face in dealing with these “legacy” systems are complex, multi-faceted, involve many teams, and often businesses face knowledge gaps in how everything works together. In the public sector, where I work, this problem of legacy systems is arguably larger and more challenging, with the need for organisations to share information, outlined by things like Digital Service Standard. But, it’s worked that way for years, so why change it?
  • Red Hat at Supercomputing 2018: Bringing open source innovation from high performance computing to the enterprise
    All supercomputers on the coveted Top500 list run on Linux, a scalable operating system that has matured over the years to run some of the most critical workloads and in many cases has displaced proprietary operating systems in the process. For the past two decades, Red Hat Enterprise Linux has served as the foundation for building software stacks for many supercomputers. We are looking to continue this trend with the next generation of systems that seek to break the exascale threshold. SC18, a leading supercomputing conference, begins today. Red Hat hopes to hold conversations and share our insights on new supercomputers, including Summit and Sierra, nascent architectures, like Arm, and building more open computing environments that can further negate the need for proprietary and monolithic implementations. The updated Top500 list is an excellent example of how open technologies continue to proliferate in high performance computing (HPC) and highlights how the ongoing software optimization work performed on these systems can benefit their performance.
  • New TOP500 List Lead by DOE Supercomputers
    The latest TOP500 list of the world’s fastest supercomputers is out, a remarkable ranking that shows five Department of Energy supercomputers in the top 10, with the first two captured by Summit at Oak Ridge and Sierra at Livermore. With the number one and number two systems on the planet, the “Rebel Alliance” vendors of IBM, Mellanox, and NVIDIA stand far and tall above the others.
  • How IBM and Red Hat Will Impact Your Cloud Strategy
    Barring a heavy-handed approach to the recent acquisition, IBM and Red Hat can do some amazing things in the market. IBM is a long way from making physical machines. That part of the business went with Lenovo several years ago. So, what has been their focus ever since? Software and services. And, among those software pieces and services has been the cloud. Until today, you may have heard little about IBM’s cloud presence. Although I can assure you it’s there, it was really struggling to compete with the likes of AWS, Azure, and even GCP. Now, with predictions like those from Gartner stating that by 2020, 90% of organizations will adopt hybrid infrastructure management capabilities and that the market in general could be worth $240 billion or more – this was as good a time as any to really take a dive into the cloud management and delivery ecosystem.
