  3. How to Ping a Port Number in Linux - Unixcop the Unix / Linux the admins deams

    Ping is a computer network administration software utility used to test the reachability of a host on an Internet Protocol (IP) network. It is available for virtually all operating systems that have networking capability, including most embedded network administration software.

    Port numbers belong to transport layer protocols, such as TCP and UDP. Port numbers help identify where an Internet or other network message forwarded when it arrives.

    So Pinging ports is one of the most effective troubleshooting technique in order to see if a service is alive or not.

    In this tutorial, we will show you how to ping a port in Linux using three different tools.

  4. How to install Apache Cassandra with Podman – NextGenTips

    Apache Cassandra is a free and open-source, distributed, wide-column store, NoSQL database management system designed to handle large amounts of data across many commodity servers, providing high availability with no single point of failure.

    Linear scalability and proven fault-tolerance on cloud infrastructure make it the perfect platform for mission-critical data.

  5. Force SSH Client to Use IPv4 or IPv6 - Putorius

    In this Linux quick tip we will discuss using command line options to force the SSH client to use IPv4 or IPv6 specifically. We will also show you how to set which IP protocol you would like to use in your SSH client configuration file.

  6. How to Install Zoom on Linux - Make Tech Easier

    “Can I install Zoom on Linux?” was the first question that came to mind when my bosses informed me that we would be working from home and using Zoom for remote meetings and one-on-one interactions with fellow employees and clients. The answer to that first question is yes, you can install Zoom on Linux. Let’s look at how to download and install the Zoom client on four different Linux distributions: Fedora, Manjaro (Arch), OpenSUSE, and Ubuntu/Debian.

  7. How to upgrade from Fedora 34 to Fedora 35 | FOSS Linux

    The official stable release of Fedora Workstation 35 was made available for download on November 2, 2021, after being pushed back to resolve some outstanding bugs. You can now install or upgrade to Fedora 35 Desktop, Fedora cloud, Fedora Servers, or any spin or labs that come with any new release cycle.

    If you prefer a fresh installation, you will have to download the latest ISO, create a bootable USB and perform a fresh install. I prefer an upgrade of the Fedora 34 system to Fedora 35. An upgrade will retain any existing files and all installed applications.

    The article is a step-by-step guide on how to upgrade to Fedora 35 via GUI (GNOME software) and the CLI method.

Okular PDF digital signature improvements coming "soon" thanks to NLnet

Starting on January I will be working on a project named "Improve Okular digital signature support" that has received a grant from the NLnet foundation as part of the NGI Assure fund. This will allow me to work part time on Okular (in case it's not clear I work on Okular on a "when I have time-hobby" basis right now), the planned improvements are: 1. Support for signing unsigned signatures. I know it sounds confusing, think about it like something like the old "sign here" boxes on printed paper forms. Read more

FPGA SoC modules gain networking carrier and new PolarFire SoC model

Enclustra’s “Mercury+ PE3” carrier for its FPGA/SoC Mercury/Mercury+ modules can act as an SBC or plug into a PC via PCIe x8. It offers QSFP+, 4x SFP+, FireFly, and 2x GbE. We also examine a new “Mercury+ MP1” module based on the RISC-V based PolarFire SoC. In May, Switzerland based Enclustra announced a Mercury+ ST1 baseboard for its FPGA/SoC powered Mercury and Mercury+ compute modules. These include a Xilinx Zynq UltraScale+ MPSoC based Mercury+ XU6 module that was announced at the same time. Now the company has unveiled a more feature-rich Mercury+ PE3 board for the Mercury/Mercury+ product line. Farther below, we report on a similarly “in development” Mercury+ MP1 module based on Microchip’s based PolarFire SoC, which includes RISC-V based CPU cores and Microchip’s PolarFire FPGA. Read more

  • IBM applauds Knative’s application to join the Cloud Native Computing Foundation

    Today, Knative applied to become an incubating project at the Cloud Native Computing Foundation. Today’s news is a major step in the right direction for the future of Knative. Knative adds the necessary components that enable Kubernetes users to more quickly deploy and manage their workloads on Kubernetes — but without the need to become Kubernetes experts. Additionally, Knative adds “serverless” runtime semantics, allowing users to reap the benefit of features such as quick load-based scaling and scaling to zero when idle.

  • 3 ways to optimize Ansible Automation Platform for scale and performance | Enable Sysadmin

    Try these settings to optimize performance with Ansible Automation Platform on a massive scale.

  • Introduction to Ansible prompts and runtime variables

    This tutorial is part of a series we dedicated to Ansible. Previously we talked about the Ansible basics, then we focused on some Ansible modules we can use to perform some very common administration tasks, and we also talked about Ansible loops. In this article, instead, we learn how to create interactive prompts we can use to ask for user input and how to pass variables at runtime.

  • MIXAL on Fedora | Adam Young’s Web Log

    The examples in The Art of Computer Programming (TAOCP) are in the MIXAL programming language. In order to see these examples run, I want to install the tools on my Fedora box. They are packaged as RPMS, so this is trivial. Here are the steps to run and debug a sample program in MIXAL.

  • Fedora Contributor Annual Survey Data Set Available – Fedora Community Blog

    Over the summer of 2021, the Fedora Council held the first annual Contributor Survey. The survey received 800 complete responses, which exceeded the goal of 500. We have processed the data, which are available for download. Coordination of the survey was a wonderful community effort. Fedora Council member Aleksandra Fedorova proposed and led the survey effort with support from Marie Nordin (FCAIC). Many teams across the Fedora Project contributed, including: the Mindshare Committee, the Outreach Revamp Team, the Design Team, the Websites & Apps Team, and the Community Platform Engineering Team. Aleksandra and Marie presented a session at Nest with Fedora which goes further into the process and outcomes. Over the last couple months, the work of cleaning up the dataset has been underway. This has been a slow process as there are just a couple of people working on that regularly. An example of “cleaning” would be folks who chose “Other”, filled in “idk”, when the option “I don’t know” existed. Those answers need to be integrated in order to have a more accurate dataset. We removed fill-in answers due to the fact that some people identified themselves, intentionally or not. As we process the data, we are noting feedback to improve the survey for 2022.
