      • ByteXDHow to Check, Open, and Close a Port on Ubuntu - ByteXD

        What is a port? In simple words: a door to a program running in your operating system. Or: application-specific or process-specific software construct used as a numeric identifier of a particular connection between two applications.

        Port numbers is a 16-bit unsigned integer that range from 0 to 65535. Applications listen for ports to achieve a successful communication from the outside.

        When dealing with a well-known distribution as Ubuntu, there are multiple tricks and features that check for, close or open ports.

        So as an alert Linux user, it’s imperative to be aware of probe for open ports in your system, which ones are open by default, closing open ports and allowing exceptions. If not, securities holes and system’s vulnerabilities would be the least of your problems, not to mention bandwidth and resource consuming connections.

      • Linux CapableHow to Install WineHQ on Linux Mint 20

        Wine is the open-source compatibility layer that allows you to run Windows applications on various operating systems, including macOS and Linux. It translates each system call your application makes into an equivalent POSIX function used across all three platforms – something which can be very helpful if one doesn’t have access or need specific features available only in Microsoft’s OSs!

        Another feature of using Wine is the Wine AppDB, a database containing lists of tested and confirmed applications that can be run under Wine. This program saves the trouble for Linux users who want to use Windows-based programs on their UNIX systems, but not all programs will work in this way; some may have strange bugs or crashes when run with no errors beforehand (even though it’s possible).

        In the following tutorial, you will learn how to install and configure Wine on Linux Mint 20 LTS release series using the command line terminal by importing the official WineHQ repository and installing the latest stable or next release titled development for those eager to try the latest bleeding-edge version of Wine for your windows compatibility needs.

      • Linux CapableHow to Install VirtualBox 6.1 on Linux Mint 20

        VirtualBox is a free and open-source hypervisor for x86 and x86-64 virtualization, which the Oracle Corporation develops. The software targets users wishing to create virtual environments for servers and desktops that allow users and administrations to run multiple guest operating systems on a single computer for either testing methods or production use. VirtualBox may be installed on Windows, macOS, Linux, Solaris, and OpenSolaris.

        In the following tutorial, you will learn how to install VirtualBox on Linux Mint 20 by importing the official virtual box repository and installing the most up-to-date version using the command line terminal. The extra benefit for users using this method is that you will receive them instantly from the VirtualBox repository when updates drop.

      • Linux CapableHow to Install/Upgrade Git on Linux Mint 20

        Git is a mature, actively maintained open source project initially developed in 2005 by Linus Torvalds, the famous Linux operating system kernel creator. Git is designed for developers that need a pretty straightforward version control system. Most software is collaborative efforts and sometimes can have hundreds of people with commits working on software development projects. Tracking these commits customarily done in branches in most projects is essential before merging into the master for release. It is easy to review and track down any incorrect commits and revert, leading to a much easier development if anything goes wrong.

        The following tutorial will teach how to install Git on Linux Mint 20 LTS release series desktop or headless server using the command line terminal and basic Git commands of everyday use.

          As the title, this is a spin-off of my last post in which I’ll talk about on Files list view instead of grid view.

          But before that, a brief summary of what happened in-between.

          Legitimate succession

          In my last post we were at the interregnum: Files grid view was temporarily managed by GtkFlowBox. Since then the switch to GTK4 has happened and with it came GtkColumnView to claim its due place.

          Despite that, GNOME 42 couldn’t ship the GTK4-based Files app (but it still benefited from it, with the new pathbar and more). Can you guess whose blame it was?

    • Remembering and Honoring Marina Zhurakhinskaya, Founder of Outreachy

      It is with great sadness that we write about the death of one of the most significant contributors to Free and Open Source Software, Marina Zhurakhinskaya. Marina was a force for change and leaves a profound legacy of diversity, inclusion, equity and justice. It is impossible to imagine what Software Freedom Conservancy and Outreachy would be like without Marina.

      Born in Kyiv, Ukraine, Marina moved to the United States after completing high school. She was accepted at the Massachusetts Institute of Technology after less than a year in the United States and graduated from MIT with a Bachelor’s and Master’s degree in Computer Science. After working at the MIT Lincoln Laboratory for several years, she joined Red Hat, a company focused on open source solutions for the enterprise market. While at Red Hat, Marina began to contribute to the GNOME desktop, working as a developer on GNOME Shell, and then became active in the GNOME community.

    • AntipopeBooks I will not write: BIGGLES!!

      It's been a long time—a couple of years—since I last posted a blog entry describing a book I will not write, because mostly I either wrote them or I just stopped having so many wasteful ideas.

      But I had a mild case of COVID19 in late May ("mild" belongs in scare quotes; it kicked my ass worse than influenza, and the lingering gastric effects are horrible, but I didn't need antivirals or hospital treatment, so yay vaccines?), and I downed tools and haven't gotten back to work yet, which is annoying to me but continuing an existing project while cognitively impaired is a really bad idea. (You generally end up spending twice as long untangling the mess you created as you spent making it in the first place.) I expect to get back to work later this week: but in the mean time, my Muse made an unexpected and unwanted house call, screamed at me for a while, and left me with an incoherent pile of notes.

      The proximate trigger for this car-crash of a story idea was the blog of another author, Rachel Manija Brown, who is currently discovering the joy of Biggles for the first time, and blogging about the books. Biggles is James "Biggles" Bigglesworth, ace pilot and adventurer, the most famous fictional creation of W. E. Johns, writing as Capt. W. E. Johns (although he only made it to Flying Officer in the RAF). They say "write what you know," and Johns clearly knew more than was strictly healthy about dogfighting during the first world war, having been there. So over 45 years or so, he wrote boys' adventure novels—lots of them.

      • IT WireMicrosoft patches 55 flaws, Follina fix finally released

        Microsoft has released patches for 55 vulnerabilities on its monthly Patch Tuesday, with the June flaws including three that were rated critical, while the remainder were classified as important.

        Nearly half the vulnerabilities detailed allowed for remote code execution, while a fifth allowed escalation of privilege.

        Claire Tills, senior research engineer at security firm Tenable, said: "Microsoft addressed CVE-2022-30136, a remote code execution vulnerability in the network file system that can be exploited by an unauthenticated attacker, assigning a CVSSv3 score of 9.8.

        "This vulnerability does not affect versions 2 and 3 of Network File System (NFS). In terms of mitigation, Microsoft has proposed disabling NFS version 4.1. However, this may have adverse effects on systems, particularly for organisations that have not applied the May 2022 security update for CVE-2022-26937. Whenever possible, organisations are strongly encouraged to update with the most recent patches."

        {loadposition sam08}Tills added that patches for CVE-2022-30190, the zero-day known as Follina that was disclosed in late May, were also included in this month’s release.

The experts criticise the plans of the EU Commission as well as the way governments of the EU member states disregard the rulings of the EU Court of Justice, especially in Belgium, Denmark, Germany, France, Ireland, Portugal and the Czech Republic. The experts elaborate on how a new generation of data retention laws threatens citizens’ fundamental rights and freedoms.

          CITIC the Chinese coal mining juggernaut churns out $8bn in revenue from its suite of Australian coal mines, gets government subsidies, but pays almost no tax and actually faxes in its one financial report to regulators. What’s the scam?

          The scam is that audit standards are bust. How do they even find a fax machine, and why do they and their auditors PwC still fax (see image below)? Perhaps because faxes fudge and are unreliable – just like the audit profession. PwC Australia has signed off on a set of accounts which shows tax paid by CITIC Australia Pty Ltd last year was just $756,000.

        In PowerDNS Recursor 4.6.0 we introduced DNS over TLS (DoT) support for outgoing connections. Starting with that version, DoT is used by default for (forwarded) connections to port 853 and for a configurable list of authoritative servers. On the client-resolver side there has been developments to make DoT discovery easy. In this post we will discuss the DoT discovery from the resolver to authoritative server perspective. PowerDNS Recursor 4.7.0 has an experimental feature implementing this.
