  • How do you handle system maintenance during a crisis? | Enable Sysadmin

    Back in the mid-1990s, a particular vendor's training classes that I was taking always began the same way: "It's not IF a failure is going to happen, it's WHEN." It's annoying to have someone repeat this mantra, no matter how true it is, at the beginning of every class. It develops an unhealthy paranoia about hardware, software, and careless sysadmins. It also helps sell more classes but that's another story.

  • Labeling all resources and objects - Linux Concept

    When SELinux has to decide whether it has to allow or deny a particular action, it makes a decision based on the context of both the subject (who is initiating the action) and the object (which is the target of the action). These contexts (or parts of the context) are mentioned in the policy rules that SELinux enforces.

    The context of a process is what identifies the process to SELinux. SELinux has no notion of Linux process ownership and does not care how the process is called, which process ID it has, and what account the process runs as. All it wants to know is what the context of that process is, represented to users and administrators as a label. Label and context are often used interchangeably, and although there is a technical distinction (one is a representation of the other), we will not dwell on that much.

  • How to organize files in Linux by classifying them into different directories

    As a technical writer, I deal with a lot of files in my job - sometimes I'm cropping images, other times I'm playing with .zip and .deb files. Not to mention PDFs and other document types we all deal with in our daily computer work.

    At present my Downloads directory contains over a thousand items, including directories, files, and images. So, I was looking for a tool that could organize at least files by classifying them into different directories. And I found one - Classifier.

    In this article, we will discuss how to install the tool and how you can use it. But before we do that, it is worth mentioning that all commands and instructions mentioned in this article have been tested on Ubuntu 20.04 LTS.

  • How to use FreeDOS as an embedded system | Opensource.com

    An embedded system is basically a very minimal system that is dedicated to run a specific task. You might think of embedded systems today as part of the Internet of Things (IoT) including sensors, thermostats, and doorbell cameras. Many embedded systems today run on Linux.

    But once upon a time, embedded systems either ran on a custom, proprietary platform or ran on DOS. Some of these DOS-based embedded systems still run today, such as cash registers or phone private branch exchange (PBX) systems. In one example as recently as 2017, trainspotters discovered a Russian electric train control system (Russian: САВПЭ) running FreeDOS with special software to control and monitor the route of suburban trains and to make passenger announcements.

  • 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.
