  • How to Secure the SSH Server in Ubuntu 20.04 from Basic to Advanced – Linux Hint

    Just like all other servers, the SSH server is also prone to unauthorized access attempts. Therefore, whenever you wish to use an SSH server, you must have considered securing it first to save yourselves from any unwanted situation in the longer run. Generally, the term “securing a server” is also known as “hardening a server.” This can be done by taking multiple measures. These measures depend upon the level of security that you require.
    The measures of securing the SSH server range from basic to advanced, and as we said earlier, you can pick them up according to the level of security that you need. You can skip any of the prescribed measures if you have sufficient knowledge about the consequences and if you are in a good position to face them. Also, we can never say that a single step will ensure 100% security, or a certain step is better than the other.

    It all depends upon which type of security we actually need. Therefore, today we intend to give you a very deep insight into the basic and advanced steps for securing an SSH server in Ubuntu 20.04. Apart from these methods, we will also be sharing with you some additional tips for securing your SSH server as a bonus. So let us get started with today’s interesting discussion.

  • Sebastian Kügler: Bringing light to life

    Some of you may be wondering what I have been up to lately since I took a break from my work in the KDE community. Well, it was time for a change, a change towards family, friends and a more local life. The result is a more balanced, a more grown up me. These changes in my life lead to me having a small family and a group of new friends, both of which I spend a lot of time with. They brought more light into my life, one could say.

  • If you want to go far, together is faster (II).

    If you work in an environment where Continuous Delivery is the norm, those behind the execution will understand which actions have a positive correlation between throughput and stability. Your job will only be associated to link those actions with the ones you are familiar with in the community health and collaboration space. If not, you work will be harder, but still worth it.

    For our particular case, you might find for instance, that a simple measure to digest the increasing number of commits (bug fixes) can be to scale up the build capacity if you have remaining budget. You might find though that you have problems doing so when reviewing acceptance criteria because you lack automation, or that your current testing-on-hardware capacity is almost fixed due to limitations in the system that manage your test benches and additional effort to improve the situation is required.

    Establishing experiments that consider not just the collaboration side but also the software delivery one as well as translating into production those experiments that demonstrate a positive correlation of the target metrics, increasing all of them, might bring you to surprising results, sometimes far from common knowledge among those focused on collaboration aspects only, but closer to those focused in execution.

  • OSI Seeks to Hire Executive Director [Ed: More evidence that the Open Source Initiative is collapsing after Microsoft took over much of it.]

    It is with great pride and excitement that I announce that OSI, as of today, is embarking on a search for an Executive Director.

    This is the culmination of many years of work and dedication on the part of countless individuals, and should be taken as a sign that OSI is maturing as an organization. We are following in the footsteps of many organizations that have come before us: nonprofits often start as a scrappy band of volunteers, which then hire staff for day-to-day operations, and eventually the staff are empowered to lead the organization.

  • Transparency

    Technology must be transparent in order to be knowable. Technology must be knowable in order for us to be able to consent to it in good faith. Good faith informed consent is necessary to preserving our (digital) autonomy.

    Let’s now look at this in reverse, considering first why informed consent is necessary to our digital autonomy.

    Let’s take the concept of our digital autonomy as being one of the highest goods. It is necessary to preserve and respect the value of each individual, and the collectives we choose to form. It is a right to which we are entitled by our very nature, and a prerequisite for building the lives we want, that fulfill us. This is something that we have generally agreed on as important or even sacred. Our autonomy, in whatever form it takes, in whatever part of our life it governs, is necessary and must be protected.


    As long as the source code that powers computing technology is proprietary and opaque, we cannot truly know whether backdoors exist and how secure we are in our digital spaces and even our own computers, phones, and other mobile devices.

        . does not chown existing directories.
      - Removed function up_to_date_p in lib/Automake/
        We believe this function is completely unused.
      - Support for in-tree Vala libraries improved.
  • TOP500 Expands Exaflops Capacity Amidst Low Turnover

    The 56th edition of the TOP500 saw the Japanese Fugaku supercomputer solidify its number one status in a list that reflects a flattening performance growth curve. Although two new systems managed to make it into the top 10, the full list recorded the smallest number of new entries since the project began in 1993.

    The entry level to the list moved up to 1.32 petaflops on the High Performance Linpack (HPL) benchmark, a small increase from 1.23 petaflops recorded in the June 2020 rankings. In a similar vein, the aggregate performance of all 500 systems grew from 2.22 exaflops in June to just 2.43 exaflops on the latest list. Likewise, average concurrency per system barely increased at all, growing from 145,363 cores six months ago to 145,465 cores in the current list.

  • Daniel Silverstone: Withdrawing Gitano from support

    Unfortunately, in Debian in particular, libgit2 is undergoing a transition which is blocked by gall. Despite having had over a month to deal with this, I've not managed to summon the tuits to update Gall to the new libgit2 which means, nominally, I ought to withdraw it from testing and possibly even from unstable given that I'm not really prepared to look after Gitano and friends in Debian any longer.

  • The 20 Best Scala Books For Beginner and Expert Developers

    Scala is an elevated level language that joins object-oriented and practical programming in one succinct. Certain static kinds of Scala help us dodge bugs in complex applications; moreover, its JVM, and JavaScript runtimes let us manufacture elite frameworks with simple admittance to colossal biological systems libraries. In the field of software, Scala is a very unique and multidimensional language. To learn Scala programming is not an easy job for someone new to this field, and therefore, a perfect set of Scala books is inevitably important for accurate guidance.

  • Comparing a new language for tiny machines

    Upstream seemed surprised that I was writing real programs in Cowgol, so I'm led to believe I might be the only one using the language. But that's fine. Let's write a simple program in C and in Cowgol so that we can compare them. Even if you're not going to use Cowgol, comparing programming languages I find to be a fun exercise and it might help you think about your own language choices, no matter what languages you choose to use.

  • macOS Leaks Application Usage, Forces Apple to Make Hard Decisions

    Last week, users of macOS noticed that attempting to open non-Apple applications while connected to the Internet resulted in long delays, if the applications opened at all. The interruptions were caused by a macOS security service attempting to reach Apple’s Online Certificate Status Protocol (OCSP) server, which had become unreachable due to internal errors. When security researchers looked into the contents of the OCSP requests, they found that these requests contained a hash of the developer’s certificate for the application that was being run, which was used by Apple in security checks.[1] The developer certificate contains a description of the individual, company, or organization which coded the application (e.g. Adobe or Tor Project), and thus leaks to Apple that an application by this developer was opened.

    Moreover, OCSP requests are not encrypted. This means that any passive listener also learns which application a macOS user is opening and when.[2] Those with this attack capability include any upstream service provider of the user; Akamai, the ISP hosting Apple’s OCSP service; or any hacker on the same network as you when you connect to, say, your local coffee shop’s WiFi. A detailed explanation can be found in this article.

  • Microsoft developing ‘Pluton’ security chip for Windows

    Microsoft will work with Intel, Advanced Micro Devices Inc. and Qualcomm Inc. to help them build Pluton into their personal computer processors. Firmware updates to CPU-integrated Pluton chips will be released by Microsoft as part of Windows updates.

  • Microsoft's new 'Pluton' security processor gets buy-in from Intel, AMD

    Advocates of the new security chip, known as Pluton, say it will cut off a key vector for data-stealing attacks: a communication channel between a computing system’s central processing unit (CPU) and another piece of hardware known as the trusted platform module (TPM). In one example of that type of attack, researchers from security company NCC Group in 2018 showed how an attacker could undermine the booting process for “a large number of TPM-enabled computing platforms.”

    The Pluton chip will be built into Windows computers through “future chips” made by AMD, Intel and Qualcomm, Microsoft said. It’s unclear when, exactly, all of that hardware will be on the market. Microsoft would only say that the work is ongoing.

  • Apple Reduces App Store Commission for Small Businesses

    Apple has been getting hit by app developers lately for its commission policy of taking 30 percent of all purchases. It has made a change that makes it seem like it will benefit smaller businesses, but critics say it really doesn’t mean much.

  • Apple spins better than Warnie as it backs down on AppStore commission

    The fact that even a company valued at US$2 trillion (A$2.7 trillion) has to sometimes heed public sentiment has been aptly illustrated by Apple announcing overnight that it would be lowering its take on apps sold from its App Store to 15% for small businesses that pull in less than a million.

  • Nordea [crackers] face prison and hefty fines, court rules [iophk: Windows TCO]

    Ostrobothnia District Court on Tuesday sentenced two men to prison terms as well as fines and compensation payments after finding the pair guilty of [cracking] into Nordea Bank's computer system in an attempt to steal several million euros.

  • The M1 Macs

    Apple, in its keynote last week, emphasized that the M1 MacBook Air has no fan. (Intel-based MacBook Airs most definitely do. The defunct 12-inch no-adjective MacBook was Apple’s only fanless Intel Mac.) Apple’s point there was to brag that the M1 runs so cool that a high-performance MacBook could be designed without one. Some Mac users, I think, mistakenly took this to mean that the Air had an advantage over the M1 MacBook Pro, in that the fanless Air would always run silently, if sometimes slower. I think this assumption was wrong: the M1 MacBook Pro is, to my ears, always silent as well. Whatever its active cooling system is doing, it isn’t making even a whisper of noise.

    No Intel-based laptop with vaguely comparable performance to these machines can possibly match that silence. If you care about noise, the game is already over.

  • Security updates for Thursday

    Security updates have been issued by Arch Linux (chromium and firefox), CentOS (bind, curl, fence-agents, kernel, librepo, libvirt, microcode_ctl, python, python3, qt and qt5-qtbase, resource-agents, and tomcat), Debian (drupal7, firefox-esr, jupyter-notebook, packer, python3.5, and rclone), Fedora (firefox), Mageia (firefox, nss), openSUSE (gdm, kernel-firmware, and moinmoin-wiki), Oracle (net-snmp), SUSE (libzypp, zypper), and Ubuntu (c-ares).

  • We can’t move forward by looking back – Open Source Security

    For the last few weeks Kurt and I have been having a lively conversation about security ratings scales. Is CVSS good enough? What about the Microsoft scale? Are there other scales we should be looking at? What’s good, what’s missing, what should we be talking about.

    There’s been a lot of back and forth and different ideas, over the course of our discussions I’ve come to realize an important aspect of security which is we don’t look forward very often. What I mean by this is there is a very strong force in the world of security to use prior art to drive our future decisions. Except all of that prior art is comically out of date in the world of today.

    An easy example are existing security standards. All of the working groups that build the standards, and ideas the working groups bring to the table, are using ideas from the past to solve problems for the future. You can argue that standards are at best a snapshot of the past, made in the present, to slow down the future. I will elaborate on that “slow down the future” line in a future blog post, for now I just want to focus on the larger problem.

    It might be easiest to use an example, I shall pick on CVSS. The vast majority of ideas and content in a standard such as CVSS is heavily influenced by what once was. If you look at how CVSS scores things, it’s clear a computer in a datacenter was in mind for many of the metrics. That was fine a decade ago, but it’s not fine anymore. Right now anyone overly familiar with CVSS is screaming “BUT CVSS DOESN’T MEASURE RISK IT MEASURES SEVERITY”, which I will say: you are technically correct, nobody cares, and nobody uses it like this. Sit down. CVSS is a perfect example of the theory being out of touch with reality.

  • Christopher Davis: Glade Not Recommended

    If you are starting out with GTK development, you may have heard of a tool called Glade. Glade is a UI designer application for GTK projects, that allows you to create, modify, and preview UI files before writing code. In that sense, Glade is a very useful tool for GTK apps.

    With that said, I must implore that you do not use Glade.

    Why? Glade was built for it’s own format, before the advent of
    GtkBuilder. It does not know certain properties, does not know
    of certain features, and does not know modern GTK practices.

  • Ventoy 1.0.29 - Neowin

    Ventoy is an open source tool to create bootable USB drive for ISO/WIM/IMG/VHD(x)/EFI files. With Ventoy, you don't need to format the disk over and over, you just need to copy the ISO/WIM/IMG/VHD(x)EFI files to the USB drive and boot them directly. You can copy many files at a time and ventoy will give you a boot menu to select them. Both Legacy BIOS and UEFI are supported in the same way. Most type of OS supported (Windows/WinPE/Linux/Unix/Vmware/Xen...)

  • Chat On Telegram From libpurple-Based IM Programs (Pidgin, Etc.) Using The New tdlib-purple

    tdlib-purple is a new libpurple plugin for Telegram, considered the successor of telegram-purple. With this you can chat on Telegram from chat clients that support libpurple, like Pidgin, Finch, Bitlbee, etc. There are binaries for Linux and Microsoft Windows.

    This libpurple plugin supports most Telegram features, from basic things like sending and receiving images and documents, and receiving stickers, to 2FA login, kick users, secret chats (support for this was added recently), and more.
    As for things that are missing, tdlib-purple doesn't support video calls, renaming groups / channels, self-destruct timers, you can't delete messages, send or receive polls, you can't send stickers, and you can't interact with bots beyond plain text messages. The application also opens muted chats and doesn't allow muting chats from the interface.

  • 8-MOSFET solid-state power driver works with Raspberry Pi, Arduino, ESP32 and other maker boards (Crowdfunding)

    Using inexpensive relays to switch AC or DC loads work well in most cases, but those relays will be quickly damaged when faced with high DC voltages, fast switching times, or other endurance requirements for which MOSFET’s are better suited, and that’s why MOSFET power supplies are found in 3D printers. Sequent Microsystems has made a habit to provide specialized Raspberry Pi HAT with relays or terminals for resistance temperature detectors that are stackable to supports a larger number for I/O or sensors. The company is now back at it with the 8-MOSFET stackable, DIN-rail mountable board that works not only with Raspberry Pi SBC, but also popular Arduino, ESP32, and other maker boards.

    Last week, we wrote about Raspberry Pi 4 Vulkan project status and future plans, and one person commented they are currently trying to get dxdk to work Box86, and that CNX Software should write about the latter. Cool, but what does that mean? dxdk is an open-source Vulkan-based implementation of D3D9, D3D10, and D3D11 for Linux, and Box86 is a Linux userspace x86 emulator that works on 32-bit Arm targets like the Raspberry Pi SBC.

    I've been playing around with the Raspberry Pi Zero W lately and having so much fun on the command line. For those uninitiated it's a tiny Arm computer running Raspbian, a derivative of Debian. It has a 1 GHz processor that had the ability to be overclocked and 512 MB of RAM, in addition to wireless g and bluetooth.


    I wanted the camera and Pi Zero W mounted on the dashboard and to be removed with ease. On boot it should autostart the RamDashCam (RDC) and there should also be 4 desktop scripts,,, Also create and a folder named video on the Desktop for the older video files. I also needed a way to power the RDC when there is no power to the vehicle's usb ports. Lastly I wanted it's data accessible on the local LAN when the vehicle is at home.

    In addition to AMD and Xilinx bringing ROCm to FPGAs, another interesting open-source/Linux milestone for the company being acquired by AMD is their publishing of the AI Engine open-source kernel driver with ambitions for upstreaming it. 

    This is a Linux kernel driver for supporting the Xilinx AI Engine, the acceleration engine providing high compute density for vector-based algorithms. The AI engine allows for custom compute and data movement and can interface with the FPGA fabric.

  • Radeon RX 6800 "Sienna Cichlid" Firmware Added To Linux-Firmware.Git

    The last piece of the puzzle to the open-source AMD Radeon RX 6800 / RX 6800 XT driver support is now upstream in its respective location.

    The Sienna Cichlid firmware binaries were just merged into linux-firmware.git, the repository where all of the firmware files for hardware devices on Linux are collected and in turn packaged up by the various Linux distribution vendors for shipping as part of their platforms.

    As with prior generations, the Sienna Cichlid firmware is necessary for any level of open-source driver support. Up until now these blobs were not public and for those yesterday wanting launch-day support or in our pre-release testing meant first extracting the firmware files from the Radeon Software for Linux 20.45 package. Or I have also heard of AMD distributing the firmware updates privately and directly to some software distribution partners for updating their packages in a timely manner as well.

    For a number of years now, we have been working hard to update and secure one of the oldest parts of the Internet, the Domain Name System (DNS). We passed a key milestone in that endeavor earlier this year, when we rolled out the technical solution for privacy and security in the DNS – DNS-over-HTTPS (DoH) – to Firefox users in the United States. Given the transformative nature of this technology and our mission commitment to transparency and collaboration, we have consistently sought to implement DoH thoughtfully and inclusively. Therefore, as we explore how to bring the benefits of DoH to Firefox users in different regions of the world, we’re today launching a comment period to help inform our plans.

  • Finding common ground through open source and conversation

    As Mark Twain once said, "let us make a special effort to stop communicating with each other, so we can have some conversation." We are bombarded with communications all day, from social media and video chats to advertisements and the news. But how much of that communication do you walk away from feeling rejuvenated or inspired?

    For the last five years, Red Hat has produced documentary films as part of our Open Source Stories series, covering education, healthcare, agriculture, the arts, citizen science, sustainability, and more. We’ve delved into stories about how open source can create meaningful change. Open Source Stories began as a conversation so it’s only fitting that in its latest evolution we’re focused on just that, conversation.

    Launching today, "Common Connections," is a series of conversations between makers featured in our films that have never met before. Scholars, CEOs, educators, and engineers will come together to find the common threads in their work, explore the potential for future open source innovation and build unexpected connections.

  • What’s new in the world of ChRIS?

    In the spring of 2018, Red Hat, together with the Massachusetts Open Cloud (MOC) and the Fetal-Neonatal Neuroimaging and Developmental Science Center (FNNDSC) at Boston Children’s Hospital, announced a collaboration to further develop and deploy the ChRIS Research Integration System. ChRIS was originally developed by the FNNDSC’s Advanced Computing Group to bring sophisticated (but often complex and hard-to-use) medical imaging, such as MRI and CT scans, analysis into the front lines to better inform clinical care. It is built on Red Hat OpenShift and Red Hat OpenStack. ChRIS has since evolved into a powerful general purpose, open source distributed data and computation platform.

  • Automate your tasks with this Ansible cheat sheet |

    Ansible is one of the primary tools in the world of automation and orchestration because of its broad usefulness and flexibility. However, those same traits are the very reason it can be difficult to get started with Ansible. It isn't a graphical application, and yet it also isn't a scripting or programming language. But like a programming language, the answer to the common question of "what can I do with it?" is "everything," which makes it difficult to know where to begin doing anything.

    Here's how I view Ansible: It's an "engine" that uses other people's modules to accomplish complex tasks you describe in a special "pseudo-code" text format called YAML.

  • Making an AppImage in Nitrux

    AppImages are the focus of our Linux distribution. We already include several AppImage-related tools that improve their user experience in our distribution, from desktop integration to sandboxing and management. Also, we include one conversely important AppImage by default, Wine (see Using Wine in Nitrux).

    In today’s tutorial, we will make an AppImage file using a tool called appimage-builder. appimage-builder makes it very easy to create AppImages of your favorite applications. appimage-builder works by using files called recipes; these are simple text files in the YML format that contain the information from which appimage-builder will make our AppImage.

    One of the main features of appimage-builder is building an AppImage from existing, pre-compiled traditional packages like Debian packages, RPM packages, etc. Currently, only Debian packages are supported; however, more package managers will be supported in the future, such as Pacman.

    Egosoft are continuing to expand their absolutely massive space simulator X4: Foundations, with a Beta now available for the free 4.0 update that will release properly early in 2021.

    It's an absolutely massive update both in terms of features and technical overhauls, so they're quite right to say that it's the "biggest free update so far" and shows just how committed they are as a studio to make X4 the best in the series.

    This update will bring in at least one major graphical upgrade with volumetric fog, although they said there will be several other wide-ranging visual improvements. The way they've implemented it sounds great too, and it sure does look good with soft layers of fog throughout space that will interact with light directly too.

Arch Linux is one of the most popular Linux distributions that’s made a name for itself for its customizability and software repositories that are replete with bleeding edge software. Arch adheres to a rolling release model, which means you can install it once and keep updating it till eternity.

For all its advantages, Arch remains one of the most cumbersome distros to configure and install. In fact, even though the installation process is one of the best documented ones, it’s elaborate and involved enough to scare away everyone except hardcore geeks.

Xfce Virtual Machine Images For Development

The openSUSE distributions offer a variety of graphical desktop environments, one of them being the popular and lightweight Xfce. Up to now there was the stable tested branch available in Tumbleweed already during install. Furthermore, for interested users the development OBS repository xfce:next offered a preview state of what’s coming up next to Tumbleweed. Xfce Development in openSUSE Thanks to the hard work of openSUSE’s Xfce team there is a third option: Xfce Development Repository aka RAT In a playful way, a rat is meant to represent the unpolished nature of this release: a rat is scruffy looking compared to a mouse (the cute and beloved mascot of Xfce). And the RAT repository provides packages automatically built right from the Git Master Branch of Xfce upstream development. The goal of this project is to test and preview the new software so that bugs can be spotted and fixed ahead of time by contributing upstream. The packages pull in source code state on a daily basis and offer a quite convenient way to test and eventually help development. So this is where the team builds and tests the latest and unstable releases of Xfce Desktop Environment for openSUSE. Read more

Radeon RX 6800 Series Performance Comes Out Even Faster With Newest Linux Code

Last week we delivered AMD Radeon RX 6800 / RX 6800 XT Linux benchmarks and the performance was great both for Linux gaming as well as the OpenCL compute performance. But for as good as those Big Navi numbers were on the open-source Linux graphics driver stack, they are now even better. That launch-day testing was based on the Linux state in the second-half of October when the cards arrived and initial (re-)testing began in preparing for the Radeon RX 6800 series reviews -- not only the Radeon RX 6800 series but re-testing all of the other AMD Radeon and NVIDIA GeForce graphics cards for the comparison too. Thanks to the rate of the open-source graphics driver progression and the newest code always being available, now just days after launch the numbers are even more compelling for Linux gamers with the slightly newer Linux 5.10 and Mesa Git compared to just weeks ago. In particular were the last minute NGG fixes and other Big Navi tweaks along with an important Radeon RX 6800 (non-XT) fix. There has also been other RADV improvements and more that accumulated in Mesa 21.0-devel this month. On the kernel side, Linux 5.10 is still at play. Both the old and newer Mesa snapshots were also on LLVM 11.0. Read more Also: Intel: AMD Gimps On Battery-Powered Laptop Performance - But DPTF On Linux Still Sucks - Phoronix
