    Today Discord has become a go-to app for team communications. One can create a Discord server and allow its members to use text or voice for sharing information. Or even create private channels to only allow certain members to join.

  • 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.

  • How To Change Timezone on Ubuntu 20.04 LTS - idroot

    In this tutorial, we will show you how to change the timezone on Ubuntu 20.04 LTS. For those of you who didn’t know, By default, when a server is provisioned a default timezone will get configured automatically with the Coordinated Universal Time (UTC). You can change the timezone later using the below method.

    This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step-by-step set or change timezone on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.

  • 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.

  • Create a git branch archive

    This week I needed to prepare some files for the buyers of my book Deployment from Scratch. I use various git repositories for the content and case studies, and I needed to create archives for the current release quickly.

    Luckily, I found out this is much easier than I made it to.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
