  • How the ping program works in Linux

    Ping is a computer program for network administration used to check the availability of active devices on the Internet or local networks. The name ping comes from sonar terminology. Ping works on the principle of echo, sending a message via ICMP protocol to a remote computer. The message contains a “request” for a response from the host. In this process, the time from the transmission of the message to the time of its receipt by the original computer (two-way) is measured and any packet loss is recorded. The test results are printed on the screen in the form of statistical messages.

    Let’s start with an example to check the connection to the google.com host. To do this, we just need to type in a terminal ping google.com, but because the program will not stop the ping alone we have to do stop it manually. To do this we must use the keyboard shortcut Ctrl + C.

  • Deploying the Mosquitto MQTT message broker on Red Hat OpenShift, Part 1 - Red Hat Developer

    Mosquitto is a lightweight message broker that supports the Message Queuing Telemetry Transport (MQTT) protocol. Mosquitto is widely used in Internet of Things (IoT) and telemetry applications, where a fully-featured message broker like Red Hat AMQ would be unnecessarily burdensome. Mosquitto also finds a role as a message bus for interprocess communication in distributed systems. Because it avoids complex features, Mosquitto is easy to tune and handles substantial application workloads with relatively modest memory and CPU resources.

    There are essentially two stages to making Mosquitto available on Red Hat OpenShift. First, you need to containerize the application in a way that is broadly compatible with OpenShift. Part of containerization involves installing the container image in a repository, from which OpenShift can download it. Second, you need to deploy the containerized image in a pod, providing whatever properties and configuration are necessary for the specific installation. The first half of this article shows how to build Mosquitto into an image suitable for use in a container. The second half will show you how to configure and deploy the Mosquitto image on OpenShift.

  • Use the DNF local plugin to speed up your home lab - Fedora Magazine

    If you are a Fedora Linux enthusiast or a developer working with multiple instances of Fedora Linux then you might benefit from the DNF local plugin. An example of someone who would benefit from the DNF local plugin would be an enthusiast who is running a cluster of Raspberry Pis. Another example would be someone running several virtual machines managed by Vagrant. The DNF local plugin reduces the time required for DNF transactions. It accomplishes this by transparently creating and managing a local RPM repository. Because accessing files on a local file system is significantly faster than downloading them repeatedly, multiple Fedora Linux machines will see a significant performance improvement when running dnf with the DNF local plugin enabled.

    I recently started using this plugin after reading a tip from Glenn Johnson (aka glennzo) in a 2018 fedoraforum.org post. While working on a Raspberry Pi based Kubernetes cluster running Fedora Linux and also on several container-based services, I winced with every DNF update on each Pi or each container that downloaded a duplicate set of rpms across my expensive internet connection. In order to improve this situation, I searched for a solution that would cache rpms for local reuse. I wanted something that would not require any changes to repository configuration files on every machine. I also wanted it to continue to use the network of Fedora Linux mirrors. I didn’t want to use a single mirror for all updates.

  • Play a fun math game with Linux commands [Ed: Those who GNU programs, but Linux commands. But Jim Hall, the author of this piece, is participating in the campaign of hate against the FSF.]

    Like many people, I've been exploring lots of new TV shows during the pandemic. I recently discovered a British game show called Countdown, where contestants play two types of games: a words game, where they try to make the longest word out of a jumble of letters, and a numbers game, where they calculate a target number from a random selection of numbers. Because I enjoy mathematics, I've found myself drawn to the numbers game.

    The numbers game can be a fun addition to your next family game night, so I wanted to share my own variation of it. You start with a collection of random numbers, divided into "small" numbers from 1 to 10 and "large" numbers that are 15, 20, 25, and so on until 100. You pick any combination of six numbers from both large and small numbers.

  • LFCA: Learn Binary and Decimal Numbers in Network – Part 10

    In Part 9 of the LFCA series, we covered the basics of IP addressing. To better understand IP addressing, we need to pay more attention to these two types of IP address representation – binary and decimal-dotted quad notation. As mentioned earlier, an IP address is a 32-bit binary number that is usually represented in decimal format for ease of readability.

    The binary format uses only the digits 1 and 0. This is the format that your computer comprehends and through which data is sent across the network.

    However, to make the address human-readable. It is conveyed in a dotted-decimal format which the computer later converts into binary format. As we stated earlier, an IP address is made up of 4 octets. Let’s dissect the IP address 192.168.1.5.

  • Ubuntu Blog: Should you ever reinstall your Linux box? If so, how?

    Broadly speaking, the Linux community can be divided into two camps – those who upgrade their operating systems in-vivo, whenever there is an option to do so in their distro of choice, and those who install from scratch. As it happens, the former group also tends to rarely reinstall their system when problems occur, while the latter more gladly jump at the opportunity to wipe the slate clean and start fresh. So if asked, who should you listen to?

    The question of system management in Linux is a complex one, with as wide a range of answers as there are distributions. In this blog post, we discuss the concept of reinstall, and whether it’s necessary. Then, we address several other closely related ideas like system imaging, full disk encryption, and data backups.

    [...]

    System problems are an unfortunate side effect of software usage. With some luck and operational discipline, you can avoid most of them. When they do happen, you want to know what to do. Reinstalling your Linux system is always an option, but it’s usually not necessary, even for various difficult, complex problems.

    Even if you do decide to reinstall, you should consider using a live session to inspect the system or perform any last-minute backups, have a solid backup procedure in place regardless, and weigh the benefits of encryption against your day-to-day needs and risks. System images can also help you reduce the hassle of getting back to speed when you do decide to “reset” your distro. That’s all we have on Linux reinstallations. If you have any comments or suggestions, please join our forum, and let us know your thoughts.

  • Timelapse: inking a comic page in Krita (uncommented)

    An uncommented timelapse while inking this page 6 of episode 34 of my webcomic Pepper&Carrot ( https://www.peppercarrot.com/ ). During the process, I thought about activating the recorder and I even put a webcam so you can see what I'm doing on the tablet too. I'm not doing it for everypages; because you can imagine the weight on disk about saving around 10h of videos like this; and also how it is not multi-tasking: when I record, you don't see me open the door to get the mail of the postman, you don't see me cleaning temporary accident of a cat bringing back a mouse at home, you don't see me typing to solve a merge request issue to merge a translation of Pepper&Carrot.

Kernel Leftovers

  • [Intel-gfx] [RFC 00/28] Old platform/gen kconfig options series
  • Patches Resubmitted For Linux With Selectable Intel Graphics Platform Support

    Back in early 2018 were patches proposed for selectable platform support when building Intel's kernel graphics driver so users/distributions if desired could disable extremely old hardware support and/or cater kernel builds for specific Intel graphics generations. Three years later those patches have been re-proposed. The patches then and now are about allowing selectable Intel graphics "Gen" support at kernel configure/build time so that say the i8xx support could be removed or other specific generations of Intel graphics handled by the i915 kernel driver. This disabling could be done if phasing out older hardware support, seeking smaller kernel images, or other similar purposes. The patches don't change any default support levels but leaves things as-is and simply provides the knobs for disabling select generations of hardware.

  • Hans de Goede: Logitech G15 and Z-10 LCD-screen support under Linux

    A while ago I worked on improving Logitech G15 LCD-screen support under Linux. I recently got an email from someone who wanted to add support for the LCD panel in the Logitech Z-10 speakers to lcdproc, asking me to describe the process I went through to improve G15 support in lcdproc and how I made it work without requiring the unmaintained g15daemon code.
