  • How To Install Multimedia Codecs In OpenSUSE

    This brief guide explains the steps to enable Packman repository in openSUSE and how to install multimedia codecs in openSUSE Leap and Tumbleweed editions from Packman repository.
    Installing codecs is one of the essential things to do in your openSUSE desktop system after doing a clean installation. Many multimedia codecs are non-free, so they are not included in the openSUSE default repositories due to legal reasons. This is why we need to add some third-party repositories like Packman, which provides various non-free packages, restricted codecs and libraries.

    Packman is the largest external repository that offers various additional packages for openSUSE. It contains all essential multimedia codecs, many audio and video player applications, games and also network related applications. Without Packman, you may not able to play many online or offline multimedia content.

    Before adding a third-party repository, you must remember that the packages hosted in a third-party repository are neither tested nor supported by openSUSE development team. Use it at your own risk.

  • How to install Deb Package on OpenSUSE Leap or Tumbleweed

    There are two ways to install Debian packages on OpenSUSE Leap or Tumbleweed, one is using SNAP to get Ubuntu-specific packages and the other by converting .Deb files into .RMP using Alien package convertor. We will show how to use both of them, here.

    OpenSUSE uses the YMP file extension but also allows the installation of RPM packages, thus we can convert easily the Debian packages that are not available to install on this Linux. However, converting packages from one format to another is one thing, and installing the same is another. I am saying this because there is no guarantee that the converted packages will get installed without any error. In such a situation, Snapcraft can help a lot because it creates an isolated environment to install packages thus doesn’t depend on the type of Linux system you are using. All the available software on its repository are installable on OpenSUSE. If you don’t want to use SNAP the Flatpak is there, however, the numbers of software packages in it are low as compared to SNAP.

  • What Is the Linux /etc/shadow File and What Does It Do?

    Poking around in your Linux system files, you might have come across a file in the /etc directory named shadow. It may sound creepy, but it's really a safe, necessary, and useful file for system administration.

    Today we'll take a closer look at the contents of the /etc/shadow file and what it can tell you about your system.

    [...]

    The shadow file really isn't mysterious at all. Remember, however, that if you want to change passwords and password rules, you should avoid editing the shadow file directly and instead opt to use tools designated for that purpose.

    Whenever you add a new user to your Linux system, the /etc/shadow file is automatically modified to store the authentication information about the user.

  • 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.
