LinuxSecurity - Security Advisories

  • [$] Possible changes to Debian's decision-making processes
    The name Debian brings to mind a Linuxdistribution, but the Debian project is far more than that; it is anongoing experiment in democratic project governance. Debian's processescan result in a lot of public squabbling; one should not lose track,though, of the fact that those processes have enabled a large community tomaintain and grow a complex distribution for decades without the benefit ofan overseeing corporate overlord. Processes can be improved, though; arecent proposalfrom Russ Allbery gives an interesting picture of where the pain pointsare and what can be made better.

  • Security updates for Friday
    Security updates have been issued by Debian (squashfs-tools, tomcat9, and wordpress), Fedora (openssh), openSUSE (kernel, mbedtls, and rpm), Oracle (httpd, kernel, and kernel-container), SUSE (firefox, kernel, and rpm), and Ubuntu (linux-azure, linux-azure-5.4).

  • Ubuntu 21.10 (Impish Indri) released
    The latest release of the Ubuntu Linux distribution is out: Ubuntu 21.10, code named "Impish Indri". The release notes fills in all of the details for the new features in this version, but the announcement lists some as well:Ubuntu Desktop 21.10 makes wayland sessions available while using the Nvidia proprietary driver. PulseAudio 15 introduces support for BluetoothLDAC and AptX codecs, as well as HFP Bluetooth profiles providing betteraudio quality. The recovery key feature at installation time has beenimproved, with the recovery key now optional, stronger and editable.Ubuntu Desktop 21.10 includes GNOME version 40, with a new andimproved Activities Overview design. Workspaces are now arrangedhorizontally, and the overview and app grid are accessed vertically.Each direction has accompanying keyboard shortcuts, touchpad gesturesand mouse actions.
    Ubuntu Server 21.10 integrates recent innovations from key openinfrastructure projects like OpenStack Xena, QEMU 6.0, PHP8, libvirt 7.6,Kubernetes, and Ceph with advanced life-cycle management tools formulti-cloud and on-prem operations from bare metal, VMWare andOpenStack, to every major public cloud.

  • Devuan 4.0 (Chimaera) released
    Version 4.0 of the Devuan distribution has been released; it is code-namedChimaera. This release is based on Debian Bullseye, has improved desktopsupport, and benefits from more accessibility work. See therelease notes for details.

  • [$] A viable solution for Python concurrency
    Concerns over the performance of programs written in Python are oftenoverstated — for some use cases, at least. But there is no getting aroundthe problem imposed by the infamous global interpreter lock (GIL), whichseverely limits the concurrency of multi-threaded Python code. Variousefforts to remove the GIL have been madeover the years, but none have come anywhere near the point where they wouldbe considered for inclusion into the CPython interpreter. Now, though, SamGross has enteredthe arena with a proof-of-concept implementation that may solve theproblem for real.

  • Plasma 25th Anniversary Edition released
    The KDE project is celebrating its 25th anniversary with a special releaseof the Plasma desktop.
    This time around, Plasma renews its looks and, not only do you get a new wallpaper, but also a gust of fresh air from an updated theme: Breeze - Blue Ocean. The new Breeze theme makes KDE apps and tools not only more attractive, but also easier to use both on the desktop and your phone and tablet.
    Of course, looks are not the only you can expect from Plasma 25AE: extra speed, increased reliability and new features have also found their way into the app launcher, the software manager, the Wayland implementation, and most other Plasma tools and utilities.
    Lots of details can be found in thechangelog.

  • Security updates for Thursday
    Security updates have been issued by Mageia (golang, grilo, mediawiki, plib, python-flask-restx, python-mpmath, thunderbird, and xstream/xmlpull/mxparser), Oracle (389-ds-base, grafana, httpd:2.4, kernel, libxml2, and openssl), Red Hat (httpd), and SUSE (kernel).

  • [$] Scrutinizing bugs found by syzbot
    The syzbotkernel-fuzzing system finds an enormous number of bugs, but, since many of them may seem to be of a relatively low severity, they have a lower prioritywhen contending for the attention of developers. A talkat the recent Linux Security Summit North America reported on some research thatdug further into the bugs that syzbot hasfound; the results are rather worrisome. Rather than a pile ofdifficult- or impossible-to-exploit bugs, there are numerous, more seriousproblems lurking within.

  • Four stable kernels
    Stable kernels 5.14.12, 5.10.73, 5.4.153, and 4.19.211 have been released with importantfixes. Users of those series should upgrade.

  • OpenBSD 7.0 Released
    Long-time Slashdot reader ArchieBunker writes:  Everyone's favorite security focused operating system OpenBSD released version 7.0 Thursday. In addition to the usual bug fixes and performance enhancements, support for RISC-V processors has been added.   It's 26 years old, and still chugging along. One interesting feature highlighted by Phoronix:  Improving the ARM64 platform support with improved drivers for the Apple Silicon / Apple M1 but still not considered ready yet for end-users. OpenBSD 7.0 improvements on the Apple M1 include support for installing on a disk with a GPT and various Apple driver improvements for USB, GPIO, SPMI, NVMe storage, and other Apple M1 hardware components.   Also check out the 7.0 Song: "The Style Hymn" (part of an archive of all the OpenBSD release songs).

  • American Bumblebees Have Disappeared From 8 States and Could Face Extinction
    Long-time Slashdot reader phalse phace quotes USA Today:  The dwindling populations of the American bumblebee and their complete disappearance from eight states has led to a call for the bee to be placed under the Endangered Species Act before they face extinction.   Maine, Rhode Island, New Hampshire, Vermont, Idaho, North Dakota, Wyoming, and Oregon each have zero or close to zero American bumblebees left, according to a petition by the Center for Biological Diversity and Bombus Pollinators Association of Law Students...   Over the last two decades, the American bumblebee population has decreased by 89% across the U.S. New York had a decline of 99% and they disappeared from the northern part of Illinois that has seen a 74% decrease in population since 2004, the petition said. Climate change, pesticides, disease, habitat loss and competition from honey bees are listed as driving the bee to extinction...  The loss of the insect could cause serious repercussions to the environment and crop production due to them being essential pollinators in agriculture. If the American bumblebee is added to the endangered species list, it will join the rusty-patched bumblebee, and If granted federal protection, anyone found to have killed or harmed the bee could face up to $13,000 in fines.

  • Former 'Donkey Kong' Record Holder Billy Mitchell May Now Sue Twin Galaxies
    "Billy Mitchell always has a plan," said Billy Mitchell in the 2007 documentary about Donkey Kong high scores, The King of Kong.   And he tweeted the phrase again Wednesday. GameSpot explains why. "Billy Mitchell, the professional gamer and hot sauce purveyor who rose to fame for setting several retro video game high scores, is preparing for a return to court."   As reported by Axios, the U.S. appeals court gave Mitchell permission to proceed with his defamation suit against Twin Galaxies, the online video game leaderboard website. In case you missed the legal tussle, the whole saga began when Twin Galaxies and Guinness World Records stripped Mitchell of his several of world records for Pac-Man and Donkey Kong after he was accused of using emulation devices to earn his scores instead of authentic arcade machines, as was required for these world record attempts. While Guinness would later reverse its decision, Twin Galaxies has so far refused to reinstate Mitchell's records.   Mitchell would file a defamation suit against Twin Galaxies in 2019, while the site itself fought back with an "anti-strategic lawsuit against public participation" — more commonly known as a SLAPP motion — response, a legal move designed to have frivolous lawsuits dismissed from court and prevent parties from being silenced, as spotted by Kotaku. This week's ruling by the State of California's Second court has stated that Mitchell and his legal team have enough material to continue the lawsuit.   Whether Mitchell and his team actually stand a chance of winning the case is another matter entirely...   Mitchell also tweeted the exact wording of the court's decision, starting with the words "Because Mitchell showed a probability of prevailing on his claims, the trial court properly denied the anti-SLAPP motion."

  • Study Discovers Workers Maintained the Same Productivity With Shorter Work Weeks
    Bloomberg reports:  Even as the Covid-19 pandemic forced companies around the world to reimagine the workplace, researchers in Iceland were already conducting two trials of a shorter work week that involved about 2,500 workers — more than 1% of the country's working population. They found that the experiment was an "overwhelming success" — workers were able to work less, get paid the same, while maintaining productivity and improving personal well-being.   The Iceland research has been one of the few large, formal studies on the subject...   [Workers] were helped by their organizations which took concerted steps like introducing formal training programs on time-management to teach them how to reduce their hours while maintaining productivity. The trials also worked because both employees and employers were flexible, willing to experiment and make changes when something didn't work. In some cases, employers had to add a few hours back after cutting them too much...  Participants in the Iceland study reduced their hours by three to five hours per week without losing pay.

  • Proposed Change Could Speed Python Dramatically
    "One of Python's long-standing weaknesses, its inability to scale well in multithreaded environments, is the target of a new proposal among the core developers of the popular programming language," reports InfoWorld: Developer Sam Gross has proposed a major change to the Global Interpreter Lock, or GIL — a key component in CPython, the reference implementation of Python. If accepted, Gross's proposal would rewrite the way Python serializes access to objects in its runtime from multiple threads, and would boost multithreaded performance significantly... The new proposal makes changes to the way reference counting works for Python objects, so that references from the thread that owns an object are handled differently from those coming from other threads.   The overall effect of this change, and a number of others with it, actually boosts single-threaded performance slightly — by around 10%, according to some benchmarks performed on a forked version of the interpreter versus the mainline CPython 3.9 interpreter. Multithreaded performance, on some benchmarks, scales almost linearly with each new thread in the best case — e.g., when using 20 threads, an 18.1x speedup on one benchmark and a 19.8x speedup on another.

  • Bitcoin Tops $60,000, Rising 50% in 24 Days
    Less than a month ago Bitcoin's price was $40,683. Last night it reached $61,369 — a gain of more than 50% in just 24 days.   CNN attributes the October surge to "hopes that the Securities and Exchange Commission will soon approve a bitcoin futures exchange-traded fund." Bitcoin prices, which rose to nearly $62,000 Friday, are now only about 5% below their all-time high of just under $65,000 that they hit earlier this year. Investors are hoping that, in addition to approving a bitcoin ETF, U.S. financial agencies will continue to take a more measured approach to regulating cryptocurrencies. Federal Reserve chair Jerome Powell and SEC chief Gary Gensler have suggested that the US won't crack down on crypto as severely as China has done. "With recent confirmation from both the Fed's Powell and SEC's Gensler that although regulations are coming, there is no China style clampdown envisioned, this will provide comfort to the broader institutional market that [bitcoin] is here to stay," said Seamus Donoghue, vice president of strategic alliances at METACO, a digital asset infrastructure provider.

  • Amazon's Ring Doorbell Can Violate Your Neighbor's Privacy, a UK Judge Rules
    An anonymous reader quotes a report from Gizmodo: A judge in the U.K. has ruled that a man infringed on his neighbor's privacy by using Amazon's Ring doorbell without prior consent. According to The Guardian, Jon Woodard had installed a Ring doorbell camera on the front of his home and another security camera facing the side yard to help deter burglars after a string of car break-ins. However, Woodard failed to disclose the cameras to his neighbor, Dr. Mary Fairhurst. Fairhurst reported being "alarmed and appalled" when she realized Woodard had recordings featuring her and her voice available on his smartphone. Fairhurst eventually moved out of her home after the two had altercations about the cameras.   Judge Melissa Clarke of Oxford county court ruled that Woodard had violated UK General Data Protection Regulation rules and the Data Protection Act of 2018, which states that "owners and residents of domestic premises must be consulted if domestic premises border the intended area to be viewed." Clarke also ruled that the video and audio captured by the Ring doorbell and cameras were Fairhurst's data and that the security devices contributed to harassment. On his part, Woodard maintained his only intention behind installing the cameras was to ward off would-be burglars. His overall fine could be up to [...] nearly $137,000. "Amazon told the Guardian that it strongly encourages its customers to respect their neighbor's privacy and 'comply with any applicable laws' when using a Ring product," adds Gizmodo. "As a general courtesy, if your cameras are pointed outwards toward someone else's property -- enough that your neighbor's faces and car license plates are occasionally in the frame -- you should let them know."

  • China Launches 6-Month Crewed Mission, Cements Position as Global Space Power
    "China launched a three-person crew into space in the early hours of Saturday," reports CNN, calling it "a major step for the country's young space program, which is rapidly becoming one of the world's most advanced..."  They will dock at China's new space station, Tiangong (which means Heavenly Palace), six and a half hours after launch. They will live and work at the station for 183 days, or just about six months... "This will certainly be their longest mission, which is quite impressive when you consider how early it is in their human spaceflight regimen," said Dean Cheng, senior research fellow at the Davis Institute for National Security and Foreign Policy.   This is the second crewed mission during the construction of the space station, which China plans to have fully crewed and operational by December 2022. The first crewed mission, a three-month stay by three other astronauts, was completed last month. Six more missions have been scheduled before the end of next year, including two crewed missions, two laboratory modules and two cargo missions. "For the Chinese, this is still early in their human spaceflight effort as they've been doing this for less than 20 years ... and for fewer than 10 missions," Cheng added. "In the past, the Chinese put up a crewed flight only once every two to three years. Now, they're sending them up every few months."  "If the Chinese maintain this pace ... it reflects a major shift in the mission tempo for their human spaceflight efforts...."   China successfully landed an exploratory rover on the moon last December and one on Mars in May. The first module of the Tiangong space station launched in April. Just last week, an international team of scientists released their findings from the moon rocks China brought back to Earth... "The European Space Agency, Russia, India, and Israel have suffered Moon or Mars probe failures in recent years; China succeeded with both on the first tries," David Burbach, associate professor of national security affairs at the US Naval War College, told CNN via email. Though the US still has the world's leading space program, he said, "there's no doubt that China is the world's Number 2 space power today."   China's ambitions span years into the future, with grand plans for space exploration, research and commercialization. One of the biggest ventures will be building a joint China-Russia research station on the moon's south pole by 2035 — a facility that will be open to international participation... Chinese astronauts have long been locked out of the International Space Station due to US political objections and legislative restrictions — which is why it has been a long-standing goal of China's to build a station of its own...   One reason space research cannot be divorced from terrestrial politics, and why the issue is so complicated, is because "the Chinese space program is heavily influenced, and its human and lunar programs are overseen, by the Chinese military," Cheng said. "Cooperating with China in space means cooperating with the Chinese military."

  • Russian Spacecraft's Thrusters Tilt the International Space Station - Again
    "Unplanned thruster firings by a Russian spacecraft briefly knocked the International Space Station off-kilter Friday, the second such incident in less than three months," reports  The spacecraft involved today was the Soyuz MS-18, which is scheduled to bring cosmonaut Oleg Novitskiy, film director Klim Shipenko and actor Yulia Peresild back to Earth early Sunday morning (Oct. 17)... "Within 30 minutes, flight controllers regained attitude control of the space station, which is now in a stable configuration," NASA officials wrote in an update this afternoon. "The crew was awake at the time of the event and was not in any danger."   The orbiting lab briefly tilted from its normal orientation this morning by 57 degrees, according to the Russian news agency Interfax, which cited communications between Novitskiy and Vladimir Solovyov, the flight director of the station's Russian segment.   Space station managers don't yet know what caused the anomalously long firing... It's also unclear why the MS-18's thrusters stopped firing, though the station's handlers have some ideas. "We think — and we haven't got confirmation — we think the thrusters stopped firing because they reached their prop[ellant] limit," NASA flight director Timothy Creamer told agency astronauts shortly after the thrusters shut down, according to The New York Times. "Moscow is checking into it and doing their data analysis."

  • Epic Says It's 'Open' To Blockchain Games After Steam Bans Them
    Epic tells The Verge that it's "open to games that support cryptocurrency or blockchain-based assets" on its game store, unlike its competitor Valve which has banned games that feature blockchain technology or NFTs from Steam. From the report: When we asked about allowing games that featured NFTs, Epic told us there'd be some limitations, but that it's willing to work with "early developers" in the "new field." Epic says that the games would have to comply with financial laws, make it clear how the blockchain is used, and have appropriate age ratings. It also says that developers won't be able to use Epic's payment service to accept crypto; they would have to use their own payment systems instead. Epic's CEO Tim Sweeney has said that the company isn't interested in touching NFTs, but that statement now appears to only apply to its own games. Epic tells The Verge that it will clarify the rules as it works with developers to understand how they plan to use blockchain tech in their games.

  • How Microsoft reduced Windows 11 update size by 40%
    Microsoft delivers the latest Windows security and user experiences updates monthly. Updates are modular meaning that, regardless of which update you currently have installed, you only need the most recent quality update to get your machine up to date. With the fast pace of Windows security and quality fixes, distributing this large amount of updated content takes up substantial bandwidth. Reducing this network transfer is critical for a great experience. Moreover, users on slower networks can struggle to keep their machines up to date with the latest security fixes if they cannot download the package. This is the kind of grunt work that doesnt get flashy slides in a presentation or a mention in a commercial, but its awesome work nonetheless.

  • First Windows 11 patch tuesday makes Ryzen L3 cache latency worse, AMD puts out fix dates
    Shortly after Windows 11 launch, AMD and Microsoft jointly discovered that Windows 11 is poorly optimized for AMD Ryzen processors, which see significantly increased L3 cache latency, and the UEFI-CPPC2 (preferred cores mechanism) rendered not working. In our own testing, a Ryzen 7 2700X Pinnacle Ridge! processor, which typically posts an L3 cache latency of 10 ns, was tested to show a latency of 17 ns. This was made much worse with the October 12 patch Tuesday! update, driving up the latency to 31.9 ns. Thats one hell of a regression. It seems fixes are incoming soon, though.

    Another month has passed, so time for another monthly update from the Haiku team. This time around, we get two for the price of one. First, the regular monthly activity report, where we can read that work on the ARM64 and RISC-V ports continues, and while these ports are nowhere near complete, they serve an important function both in discovering bugs and issues, as well as in getting Haiku ready for future architecture transitions. Tracker also received thumbnail support, but this is disabled by default for now, and of course, theres a lot of low-level work being done, too. The second update comes from waddlesplash, Haiku Inc.s actual paid full-time developer. In his report, he details his work on fixing two Haiku bugs that caused frequent crashes in WebKit, as well as extensive work on the USB stack  more specifically, improving USB 3.0 support. On top of that, he also details a lot of his low-level work over the month of September.

  • The insane innovation of TI calculator hobbyists
    In the mid-to-late 2000s, you either knew, or were, that kid in grade school. You know. The one who could put games on your graphing calculator. You may be surprised to learn that some of these people didn’t exist totally in a vacuum. There was in fact a thriving scene of hackers who had bent these calculators to their will, writing games, math software, and more generally hacking on the platform just for the sake of it. True to my interests, it’s all deeply embedded, pushing the limits of platforms that were obsolete when they were released. I’ll take you through some of the highlights of Texas Instruments calculator hacking done over the past two and a half decades, along with an explanation of why these projects are so technically impressive. A friend of mine and I at high school bought the data transfer cable for our graphing calculators so we could play multiplayer Bomberman on them in class. Good times.

  • 7 Important Linux Commands for Every Linux User
    by Suparna Ganguly    Linux might sound scary for first-time Linux users, but actually, it isn’t. Linux is a bunch of open-source Unix operating systems based on Linux Kernel. These operating systems are called Linux distributions, such as Fedora, Debian, Ubuntu, and Mint.
    Since its inception in 1991, Linux has garnered popularity for being open-source. People can modify and redistribute Linux under their own brand. When using a Linux OS, you need a shell to access the services provided. Also, it’s recommended to run your Linux OS through a CLI or command-line interface. CLI makes time-consuming processes quicker.
    This article presents a guide to 7 important Linux commands for every Linux user to know. So, let’s begin.
    cat Command  cat is the shortened form of “concatenate”. It’s a frequently used multi-purpose Linux command. This command is used to create, display, and copy a file content on the standard output.
    Syntax   cat [OPTION]... [FILE]..  To create a file, type:
     cat >   // Enter file content  To save the file created, press Ctrl+D. And to display the file content, execute:
     cat   cd Command  The cd command is used to navigate through the directories and files in Linux. It needs either the entire path or the directory name depending on the current directory.
    Syntax   cd [Options] [Directory]  Suppose you’re in /home/username/Documents. You want to navigate to a subdirectory of Documents which is Photos. To do that, execute:
     cd Photos  To move to an entirely different directory, type cd and then the directory’s absolute path.
     cd /home/username/Movies  The above command will switch to /home/username/Movies. Apart from this, the commands, cd.., cd, and cd- are used to move one directory up, to go to the home folder, and to go to the previous directory respectively.
    Reminder: Linux’s shell is case-sensitive. So, make sure you type the name’s directory as it is.
    echo Command  The echo command displays a line of text or string passed as an argument. It’s used for the purpose of debugging shell programs in the Linux terminal.
    Syntax   echo [Option] [String]  Other examples of the echo command are:
      echo "String": This displays the string within the quotes.
        echo -e "Learn \nBy \nDoing": Here the ‘-e’ tag allows the echo command to understand the backslash escape sequences in the argument.

  • In PuTTY, Scripted Passwords are Exposed Passwords
    by Charles Fisher   
    PuTTY is one of the oldest and most popular SSH clients, originally for Windows, but now available on several platforms. It has won corporate support and endorsement, and is prepared and bundled within several third-party repositories.

    Unfortunately, the 0.74 stable PuTTY release does not safely guard plain-text passwords provided to it via the -pw command line option for the psftp, pscp, and plink utilities as the documentation clearly warns. There is evidence within the source code that the authors are aware of the problem, but the exposure is confirmed on Microsoft Windows, Oracle Linux, and the package prepared by the OpenBSD project.

    After discussions with the original author of PuTTY, Simon Tatham developed a new -pwfile option, which will read an SSH password from a file, removing it from the command line. This feature can be backported into the current 0.76 stable release. Full instructions for applying the backport and a .netrc wrapper for psftp are presented, also implemented in Windows under Busybox.

    While the -pw option is attractive for SSH users who are required to use passwords (and forbidden from using keys) for scripting activities, the exposure risk should be understood for any use of the feature. Users with security concerns should obtain the -pwfile functionality, either by applying a patch to the 0.76 stable release, or using a snapshot release found on the PuTTY website.
    The psftp, pscp, and plink utilities are able to accept a password on the command line, as their usage output describes:

  • How To Pick a Linux Distribution for Non-Techies
    by Ujjwal Anand    I have suffered from distrohopping. Now that I have settled for the last two years, here are some tips to save your time.
      All distros run the same operating system at their core, Linux. They are more similar than different. Hence, the marginal cost (time) of looking for a better distro is much more than the marginal benefit of it.
        Say no to distributions made for specific purposes like Kali, CentOS, and OpenSuse. OpenSuse is great, but it is made for enterprise use. An everyday user won't ever need most of its features. To maintain it would be a waste of time. The same goes for the RedHat family.
        Instead of trimming Suse, you better pick a distro made for everyday people, such as AntiX and SolusOS. Read their descriptions and target users on Distrowatch.
        Avoid technical distributions like arch, its forks, and Gentoo. They are for the programmer types. If you are not one, you will likely break it. Updates tend to be massive and very frequent. And you can't install a new package without updating first. You don't want to deal with this. If you want it only for AUR, just learn to compile a little bit.
        Say no to most desktop environments (DEs) besides LXDE and LXQT. Prefer window managers (WMs) for maximum performance. DEs can be buggy and cause distraction. They increase boot time and update size. It may be reasonable to rule out all distros that don't come with a window manager so you don't have to do the work post-installation. Know the rule; the less stuff you have, the fewer things you can break, the fewer problems you will face. Keep it minimal. Don't allow the bling-bling to distract you.
        Try out different Init systems. Ever since systemd was adopted, Linux has started to feel like Windows, complex and out of hand. I do have it on Manjaro (but I did have to mask a couple of unneeded services to lower the boot time). A particular init system might work better on your specific hardware. Try some isos on a virtual machine.
        Avoid forks because they simply are not different enough. In addition, they tend to carry their parent distro's issues on top of their own issues. Developers can do only so much about it. Independent distributions can fix issues more quickly because they can. Prefer original and independent distros.
        Don't worry about software availability. Every distro hosts tools to help you install packages not present in their repos. Furthermore, package managers like Appimage and Flatpak allow you to install packages on all distros. Avoid snap. It slows down bootup and doesn't allow you to control app updates. This may change in the future though.

  • What’s New in Debian 11 “Bullseye”?
    Debian is a preferred choice of millions of Linux users for some of the most popular and powerful operating systems, like Ubuntu and its derivatives are based on Debian.
    Debian 11has finally been released, finally, after a long development work of two years. Bullseye – that’s the name given to this latest Debian Linux distro. So what are the updates and upgrades? In this article, let’s check out what’s new in Debian 11.
    Debian 11’s Architecture  Debian supports a good range of hardware architectures. 
    Supported Architectures
    ARM EABI (armel)  ARMv7 (EABI hard-float ABI and armhf)  64-bit ARM (arm64)  32-bit PC (i386)  64-bit PC (amd64)  Little-endian MIPS (mipsel)  64-bit little-endian PowerPC  64-bit little-endian MIPS  IBM System z (s390x) Not Supported Hardware
    Old MIPS 32-bit CPUs Linux Kernel Information  Debian 11 supports the Linux Kernel 5.10 LTS. Debian 10 Buster, the earlier version to Debian 11, used Linux Kernel 4.19 while released. A newer kernel means a new set of bug fixes, new hardware support, and improved performance.
    This is the perfect kernel for Debian bullseye considering the Debian lifecycle.   
    Supports exFAT  exFAT is the shortened form of the Extensible File Allocation Table. It’s a filesystem used for flash memory, such as SD cards and USB flash drives.
    Now Debian 11 provides support for the exFAT. For mounting the exFAT filesystem, you don’t need the filesystem-in-userspace implementation provided by the exfat-fuse package additionally anymore. Thanks to kernel 5.10! exFAT comes in handy with it. Tools for checking and creating an exFAT are given in the exfatprogs package.
    Bauhaus Movement Inspired Theme & Wallpaper  Debian features cool wallpapers and a default theme for each of the major releases. Debian 11’s theme is inspired by the Bauhaus movement. Bauhaus means “building house” and it was an art and design movement from 20th century Germany. The Bauhaus movement revolved around abstract, geometric style featuring little emotion or sentiments. 
    Its modern aesthetic still is immensely influential for designers, architects, and artists. You can see this theme all through Debian 11 whether it’s the installer, login window, or the Grub menu.
    Newer Desktop Environment Versions  Debian 11 offers newer desktop environment versions. Desktop flavors you get here are, KDE Plasma 5.20, GNOME 3.38, LXDE 11, LXQt 0.16, Xfce 4.16, and MATE 1.24. Debian prefers stability and it’s quite clear from the desktop environments. You might not get the latest cutting-edge distributions like Fedora or Arch/Manjaro.
    Updated Packages  Debian 11 consists of more than 11,294 new packages out of 59,551 packages. It also reduced over 9,519 “obsolete” packages and removed 42,821 that were updated. A total of 5,434 packages remained as they were.
    A good number of software applications and package updates are included in Debian bullseye, such as Apache 2.4.48, Calligra 3.2, Emacs 27.1, LibreOffice 7.0, Inkscape 1.0.2, Linux kernel 5.10 series, Perl 5.32, PHP 7.4, Vim 8.2, PostgreSQL 13, and the list goes on. All these ready-to-use software packages are built with over 30,000 source packages.
    With this huge selection of packages and wide architecture support, Debian has always stayed committed to its aim of being The Universal Operating System.
    Improved Printer and Scanner Features  Debian 11 presents a new ipp-usb package. It is built with a vendor-neutral IPP-over-USB protocol that is supported by many latest printers. So, many modern-day printers will be supported now by Debian. And you won’t need the drivers for that.
    SANE driverless backend lets you use scanners without any trouble.
    Endnotes  Want to try Debian Bullseye? Get it from here. You can also check “bullseye” with Live Images without installing it on your PC. This will load and run the entire OS in read-only mode. These live images are available for the i386 and amd64 architectures in the form of USB sticks, DVDs, and netboot setups. Debian Live has a standard image. So you can try a basic Debian without any GUIs.
    And that’s the ending of this article. Hope you find our Debian 11 guide helpful.

  • In Search of Linux Laptops? Check these 6 Places to Get Your Laptop in 2021
    by Suparna Ganguly    Are you in search of Linux laptops? This article takes you through 6 different places that offer the best Linux laptops. So get prepared to choose your Linux laptop in 2021.
    Dell  When it comes to laptops, the first name that comes to my mind is Dell. For over 20 years Dell has been selling high-end Linux laptops. In a Dell store, you can get Ubuntu and Redhat Enterprise Linux laptops. These laptops are built to meet the needs of developers, businesses, and sysadmins.
    For developers, who travel a lot, XPS 13 Developer Edition would be the confirmed best choice. Dell XPS comes at an expensive cost of around $1,000. So, if you’re in search of something less expensive, you can check Dell Inspiron laptops. Dell’s Precision workstationswith RHEL or Ubuntu are designed for small business owners or CG professionals.
    Side Note: Dell doesn’t have a separate section for Linux laptops. Type Ubuntu in the search to get a view of all its laptops with Linux preinstalled.
    Slimbook  Slimbook is well known for its thin, rigid, and light durable laptops starting at a reasonable price of €930 (approx $1,075). These come with a nice screen, solid battery life, powerful CPU, and very good speakers.
    This brand is from Spain. Slimbook came ahead of its competitors launching the first KDE laptops.
    Slimbook brings laptops with a good variety of popular Linux distros, such as KDE Neon, Ubuntu, Ubuntu MATE, Linux Mint, Kubuntu. Additionally, their laptops have two Spanish Linux distros – Max and Lliurex. You can choose Windows OS as well with their laptops, but for that, additional costs are there.
    Slimbook offers desktop systems too. So, if you ever need desktops, check it here
    System76   System76s Linux laptops are very well built, powerful, and extremely portable. If you are a software developer, you travel a lot, and you’re in search of a laptop with 32G RAM and 1T SSD, then go for System76.
    System76 laptops used to be Ubuntu-powered, initially. Later on, in 2017, this US-based company released their own Linux distro, called the Pop! OS. Pop OS is designed using Ubuntu. After that, Pop became the default OS with Ubuntu being still available.

  • Q&A trip to Linux’s Black Hole - /dev/null
    by Nawaz Abbasi    As per NASA, “A black hole is a place in space where gravity pulls so much that even light can not get out”. Something similar exists in the Linux universe as well - it discards anything written to it and when read, just returns an EOF (end-of-file). It’s a special file which is also referred to as null device - /dev/null
    So, it’s just a file?  Yes and most of the things in Linux is a file but /dev/null is not a regular file – lets dig deeper.

    c in crw-rw-rw- tells us that it's a character special file, which means it processes data character by character. This can be checked using test -c as well:

    What are the contents of the file?  Let’s check that using the cat command:

    As stated earlier, it just returns an EOF (end-of-file) when read. So, it's empty!
    What more can we know about the file?  Let’s find out using the stat command:

    This tells us that its size is 0. Also, it’s good to note that the file’s read and write permission is enabled for everyone but it doesn't require execute permission. 
    What happens to the file’s size when we write data to it?  Let’s try that:

    The cat command returned nothing and as per the stat command, its size did not change.
    As stated earlier, it discards anything written to it. You may write any amount of data to it, which will be immediately discarded, so its size will always remain 0 – Singularity?
    In other words, you cannot change /dev/null

  • Download These 7 Cool Apps on Your Linux Machine to Make Life Easier
    by Suparna Ganguly    Not only the Linux distros are open-source but the apps for Linux are also free. Though some business apps come with a cost, most of the apps created for individuals don’t have any charges.
    Want to know about some of the cool apps to download on your Linux machine?
    This article walks you through 7 apps to download on Linux to make your life easier. Head over to the next section!  
    Ulauncher  Before downloading any other application on Linux, we recommend getting Ulauncher. That’s because you can launch any application via Ulauncher just by using the keyboard.
    Try adding Ulaucher extensions to get the most of this app inspired by Alfred for Mac. You can extend capabilities with the extensions, such as looking up dictionary definitions, launching web searches, finding and copying emojis to a clipboard, and lots more.
    Ulaucher runs smoothly and allows searching files and apps using hotkeys. Ulaucher features include built-in themes, customizable shortcuts, Fuzzy search, a wide variety of plugins, searching on Google, Stack Overflow, and Wikipedia.
    Thunderbird  Thunderbirdby Mozilla is an open-source email client. Some Linux distros offer Thunderbird installed. If it’s not, hop onto your App Center or Software Center and get it installed. You can download the app from their website as well.
    The setup wizard guides you through the process of creating your own email address. Thunderbird provides email settings for most of the common email application providers. So, an existing email account can be added too. Attach multiple email accounts as per your needs.
    Want to make Thunderbird look cool? Add-ons, such as themes, Lightning extension, sorting out Mail folders, are some of the features to try out.
    Steam  Looking for gaming clients on Linux? Use Steam from Valve. Steam is, admittedly, the best games distribution store for top OSs like Linux.
    From Shadow of the Tomb Raiderto DiRT 4, and from DOTA 2 to Warhammer – Steam boasts many thousands of indie hits, retro-flavored, and AAA titled games for Linux

  • Improve The CrowdSec Multi-Server Installation With HTTPS Between Agents
    by Manuel Sabban    Prerequisites  This article is a follow-up from the Crowdsec multi-server setup. It applies to a configuration with at least two servers (referred to as server-1 and one of server-2 or server-3).
    Goals  To address security issues posed by clear http communication in our previous crowdsec multi-server installation, we propose solutions to achieve communication between Crowdsec agents over encrypted channels. On top of that, the third solution allows server-2 or server-3 to trust server-1 identity, and avoid man-in -the -middle attacks.
    Using self-signed certificates  Create the certificate  First we have to create a certificate. This can be achieved with the following one-liner.
     openssl req -x509 -newkey rsa:4096 -keyout encrypted-key.pem -out cert.pem -days 365 -addext "subjectAltName = IP:"  For now crowdsec is not able to ask for the passphrase of the private key when starting.  Thus we have the choice to decipher by hand the private key each time we start or reload crowdsec or store the key unencrypted. In any way to strip the passphrase one can do:
     openssl rsa -in encrypted-key.pem -out key.pem  Then, the unencrypted key file can be safely deleted after Crowdsec is started.
    Configure crowdsec for using a self-signed certificate  On server-1 we have to tell crowdsec to use the generated certificate. Hence, the  tls.cert_file and tls.key_file option in the api.server section of the following /etc/crowdec/config.yaml excerpt set to the generated certificate file.
     api:   server:   log_level: info   listen_uri:   profiles_path: /etc/crowdsec/profiles.yaml   online_client: # Crowdsec API credentials (to push signals and receive bad    tls:   cert_file: /etc/crowdsec/ssl/cert.pem   key_file: /etc/crowdsec/ssl/key.pem  On the client side configuration changes happen in two files. First we have to modify /etc/crowdec/config.yaml to accept self-signed certificates by setting the insecure_skip_verify to true.
    We have to change http for https in the  /etc/crowdsec/local_api_credentials.yaml file too in order to reflect the changes. This small change has to be done on all three servers (server-1, server-2 and server-3).
