How to enable SSH access using a GPG key for authentication

Linux
Security
HowTos

Many of us are familiar with Secure Shell (SSH), which allows us to connect to other systems using a key instead of a password. This guide will explain how to eliminate SSH keys and use a GNU Privacy Guard (GPG) subkey instead.

Using GPG does not make your SSH connections more secure. SSH is a secure protocol, and SSH keys are secure. Instead, it makes certain forms of key distribution and backup management easier. It also will not change your workflow for using SSH. All commands will continue to work as you expect, except that you will no longer have SSH private keys and you will unlock your GPG key instead.

  • The Free Software Directory needs you! IRC meetups every Friday

    The Free Software Directory is an essential catalog of free software online. The Directory is maintained by countless volunteers dedicated to the promotion of software that respects your personal liberty. As with any group composed of volunteers, the informal Directory team has people who come and go, and right now, it could really use some fresh new members to kick our efforts into high gear.

    Tens of thousands of people visit the Directory every month to discover free software and explore information about version control, documentation, and licensing. All of this information is also exported in machine-readable formats, making it a valuable source of data for the study of trends in free software. The Directory is powered by MediaWiki, the same software used by Wikipedia.

  • Builder 3.33.1

    Our first 3.33 release has landed as we move towards 3.34. There is a lot to do this cycle in case you’re interested in contributing. The best way to get started is to dive into the code. We can help you with that on IRC.

    Lots of this release is code behind the scenes, so screenshots won’t do them justice. But there are some visible goodies too.

    We got a DBus Inspector inspired by D-feet. The long term goal is to merge that new code into D-feet itself.

  • GtkSourceView moved to Meson

    The master branch of GtkSourceView (what will become 4.4) has moved to meson for development. I branched gtksourceview-4-2 for patch releases of 4.2.x which will remain autotools. Today’s release of gtksourceview-4.3.1 contains both autotools and meson. However 4.3.2 will remove autotools entirely.

  • Acquisition roundabout sees Zend Framework spun off to Linux Foundation

    The Zend Framework is to get a new name and a new home, under the auspices of the Linux Foundation, just a few months after its parent co was itself swallowed whole.

    Zend – as was – is an open source, object-oriented web application framework implemented in PHP 7. It was synonymous with Zend Technologies, which was taken over by Rogue Wave Software in 2015. Rogue Wave Software was itself acquired by private equity outfit Clear Lake Capital earlier this year.

    According to the website for the new organisation, “To take it to the next step of adoption and innovation, we are happy to announce that we are transitioning Zend Framework and all its subprojects to an open source project hosted at the Linux Foundation.”

  • Five RESTful web service client examples for developers

    How do you access a RESTful web service? That depends on what you're trying to accomplish.

    If you just want to test connectivity, a terminal-based utility like curl is a great RESTful web service client. If you want to inspect the JSON a service returns to you, a browser-based plugin will probably be a better fit. And if you are in the midst of application development, you'll likely need to use JAX-RS, Spring or a similar framework.

  • 5 Best Reasons to Opt for PHP Web Development

    Many companies now are choosing PHP web development to realize their IT needs. According to research, almost 83 percent of web services are using PHP, and it is the preferred choice of industry stalwarts such as BlaBlaCar, Slack, and Spotify. PHP is open source and comes with a great community, and it is continuously upgrading. There is no doubt about the same.

  • It’s Complicated: Mozilla’s 2019 Internet Health Report

    The Report paints a mixed picture of what life online looks like today. We’re more connected than ever, with humanity passing the ‘50% of us are now online’ mark earlier this year. And, while almost all of us enjoy the upsides of being connected, we also worry about how the internet and social media are impacting our children, our jobs and our democracies.

    When we published last year’s Report, the world was watching the Facebook-Cambridge Analytica scandal unfold — and these worries were starting to grow. Millions of people were realizing that widespread, laissez-faire sharing of our personal data, the massive growth and centralization of the tech industry, and the misuse of online ads and social media was adding up to a big mess.

    Over the past year, more and more people started asking: what are we going to do about this mess? How do we push the digital world in a better direction?

    As people asked these questions, our ability to see the underlying problems with the system — and to imagine solutions — has evolved tremendously. Recently, we’ve seen governments across Europe step up efforts to monitor and thwart disinformation ahead of the upcoming EU elections. We’ve seen the big tech companies try everything from making ads more transparent to improving content recommendation algorithms to setting up ethics boards (albeit with limited effect and with critics saying ‘you need to do much more!’). And, we’ve seen CEOs and policymakers and activists wrestling with each other over where to go next. We have not ‘fixed’ the problems, but it does feel like we’ve entered a new, sustained era of debate about what a healthy digital society should look like.

Mesa Graphics: AMD and RADV

  • RADV Vulkan Driver Lands FreeSync/Adaptive-Sync For Mesa 19.1

    While on the kernel-side there has been FreeSync support with the AMDGPU DRM driver since Linux 5.0 and for the OpenGL driver with RadeonSI there has been this functionality in Mesa 19.0 when paired with a supported kernel, the Mesa Radeon Vulkan driver has missed out on this action until now. But landing just in time for the Mesa 19.1 feature freeze is now the FreeSync/Adaptive-Sync enablement for RADV.

  • A Decade Later, Mesa Wiring In Support For Qualcomm/AMD's ATC Texture Compression

    Adding to the list of Mesa 19.1 changes is now AMD_compressed_ATC_texture being plumbed into Mesa/Gallium3D primarily with a focus on the Freedreno driver.

    AMD_compressed_ATC_texture is the extension worked on a decade ago by AMD/Qualcomm for ATC compressed texture formats. ATC was AMD's proprietary compression algorithm with a focus on mobile devices for power and memory bandwidth savings. That was right around the time ATI/AMD Imageon IP was sold off to Qualcom to form the Adreno graphics processors for the company's SoCs.

  • How hacking threats spurred secret U.S. blacklist

    U.S. energy regulators are pursuing a risky plan to share with electric utilities a secret "don't buy" list of foreign technology suppliers, according to multiple sources.

    The move reflects the federal government's growing concern that hackers and foreign spies are targeting America's vital energy infrastructure. And it's also raised new questions about the value of top-secret U.S. intelligence if it can't get into the hands of power industry executives who can act on it to avoid high-risk vendors.

    Joseph McClelland, director of the Federal Energy Regulatory Commission's Office of Energy Infrastructure Security, told a Department of Energy advisory committee last month that officials are working on "an open-source procurement list" for utilities to use when deciding where to source their software and equipment.

  • Why AI + consumer tech?

    After talking to nearly 100 AI experts and activists, this consumer tech focus feels right for Mozilla. But it also raises a number of questions: what do we mean by consumer tech? What is in scope for this work? And what is not? Are we missing something important with this focus?

    At its simplest, the consumer tech platforms that we are talking about are general purpose internet products and services aimed at a wide audience for personal use. These include things like social networks, search engines, retail e-commerce, home assistants, computers, smartphones, fitness trackers, self-driving cars, etc. — almost all of which are connected to the internet and are fueled by our personal data. The leading players in these areas are companies like Google, Amazon, Facebook, Microsoft and Apple in the US as well as companies like Baidu, TenCent, and AliBaba in China. These companies are also amongst the biggest developers and users of AI, setting trends and shipping technology that shapes the whole of the tech industry. And, as long as we remain in the era of machine learning, these companies have a disproportionate advantage in AI development as they control huge amounts for data and computing power that can be used to train automated systems.

Devices: Airtop3 With Linux Mint and Debian's Jonathan McDowell Studies a PCB

  • Airtop3 Manages A Passively-Cooled Core i9 9900K + Quadro RTX 4000

    CompuLab today announced the Airtop3, the latest in their series of industrial-grade, excellently built fanless PCs. The CompuLab Airtop we benchmarked back in 2016 while showing its age now with the Core i7 5775C Broadwell processor is still running strong with its original design and even after what's been hundreds if not thousands of hours of benchmarking workloads still is running strong. Then again, that isn't too surprising as we continue to be improved by their build quality now after benchmarking their systems with Linux for the past decade.

  • Fanless mini-tower runs Linux Mint on up to 5GHz octa-core i9-9900K

    Compulab’s passively cooled, Linux-friendly “Airtop3” mini-tower builds on a 9th Gen, octa-core Intel Core i9-9900K with Quadro RTX 4000 graphics plus up to 128GB DDR4, NVMe and SATA storage, triple displays, 2x GbE, 6x USB 3.1, and -40 to 70°C support.

    Compulab has launched a redesigned Airtop IoT edge server that accomplishes the challenging task of passively cooling Intel’s high-end, 9th Gen Core i9-9900K processor. The Airtop3 is “nearly” twice as powerful as the 7th Gen Kaby Lake based Airtop2 mini-tower while maintaining the fanless, embedded-oriented design, says Compulab. Linux Mint and Windows 10 Pro are available.

  • Jonathan McDowell: Making my first PCB

    I then started to notice I was getting JLCPCB ads while web browsing, offering 10 PCBs for $2. That seemed like a good deal, and I thought if I did things right I could find the right case and then make sure the PCB fitted in it. I found a small vented white case available from CPC. This allows me to put a temperature sensor inside for some devices. KiCad seemed like a good option for trying to design my basic schematic and lay it out, so I installed it and set to work trying to figure out what I wanted to put on the board, and how to actually drive KiCad.

    As the core I chose an ESP-07 ESP8266 module. I’ve used a few of them before and they’re cheap and convenient. I added an LDO voltage regulator (LD1117) so I could use a 5V PSU (and I’m hoping with a heatsink I can get away with a 12V supply as well, even if it’s more inefficient). That gave enough to get a basic schematic once I’d added the necessary pull-up/down resistors for the ESP8266 and decoupling capacitors. I included a DC barrel jack for the PSU, and pin headers for the serial port, SPI pins and GPIO0 for boot selection. One of my use cases is to make an LED strip controller, so I threw in a screw terminal block for power + control - the board is laid out to allow a MOSFET for a simple white 12V LED strip, or the same GPIO taken straight to the terminal block for controlling a WS2812 strip. By including a couple of extra pull-up resistors I added the option of I2C for further expansion.

    After I had the basic schematic I moved to layout. Luckily Hammond provide 2D CAD files for the case, so I figured I would import them into KiCad’s PCB layout tool to make sure things would fit. That took a little bit of effort to go from DWG to DXF and trim it down (I found a web tool to do the initial conversion and then had to strip out the bits of the case that weren’t related to the PCB size + mounting points). I wasn’t confident enough that the edge cuts layer would include the mounting holes, so I manually placed some from KiCad over the right spots.

  • Why Hybrid Cloud is About to Get a Whole Lot Easier

    It seems like analysts, vendors and IT decision makers have been talking about “hybrid cloud” for the longest time. The concept has been around for at least a decade – and that’s a really long time in the IT industry. Is it still important? Absolutely.

  • Intel Iris Gallium3D Picks Up Conservative Rasterization Support
    On top of Intel's new open-source OpenGL driver seeing some hefty performance optimizations, the Iris Gallium3D driver has picked up another OpenGL extension ahead of the Mesa 19.1 branching.  Iris Gallium3D now supports INTEL_conservative_rasterization alongside the existing support in the i965 driver. INTEL_conservative_rasterization is the several year old Intel extension for seeing if all fragments are at least partially covered by a polygon rather than the default rasterization mode of including fragments with at least one sample covered by a polygon.
