Ansible — configuration management system: getting to know it

Thu, 07 Nov 2024 00:00:00 +0000

In this note we will get acquainted with a popular open source configuration management system with the telling name — Ansible 🎻. We’ll perform the installation and configuration 🛠, put together an inventory 📋, learn how to run playbooks 🚀, talk about Ansible facts 🗂, find out what Ansible console 🖥 is, and write a playbook 📝 that fixes the sshd config and copies files to the server. It’s going to be informative 😉!

Linux command line, privilege escalation: su, sudo commands

Wed, 11 Sep 2024 00:00:00 +0000

Greetings!

We continue studying the Linux command line. Today we’ll learn how to properly run commands on behalf of another user, including the root user. We’ll get familiar with the su and sudo commands, and also learn how to correctly grant limited privileges to users and groups.

Along the way, let’s figure out why sudo su is like saying: “Open the door for me,” and then demanding again: “And let me in right now!"😁.

Native upgrade from Linux Mint 21.3 to Linux Mint 22

Wed, 07 Aug 2024 00:00:00 +0000

Greetings!

A new release of the Linux Mint 22 distribution (based on Ubuntu 24.04) codenamed Wilma has just come out. And just recently the developers prepared instructions and a tool for a native (without reinstalling the OS) system upgrade, from Linux Mint 21.3 to Linux Mint 22. In this short note I’ll demonstrate this simple process 😉

I’d like to note that my test system has been upgraded this way since Linux Mint 20. Still alive so far)

Linux command line, introduction: command types, plain text, file system, shell prompt

Greetings!

I present to your attention the first (introductory) part of a series of posts devoted to working in the Linux command line. This post is a kind of foundation for future entries on this topic. It will be followed by posts with descriptions and practical examples of using popular console utilities.

I’ll give one recommendation right away. If you want a comprehensive resource on the Linux command line, I recommend reading William Shotts’ book with the simple title: The Linux Command Line. This book is an excellent source that lets you thoroughly study the basics of working in the Linux console. Material from this book will also be used and quoted in this and future posts about Linux.

Greetings!

We continue the gradual transition to free Linux-based operating systems.

To refresh your memory, or in case you missed them, here are two previous articles:

So, we tried Linux Mint 20 in Windows using virtualization technology, then installed it as a second OS side by side with Windows. And now it’s time for the initial setup of the Linux Mint operating system.

Installing Linux alongside Windows

⚠️ Warning

Right away, I want to point out that everything described in this guide, you do at your own risk. If you have experience reinstalling or restoring Windows systems, then you have nothing to worry about. But just in case, before you start, back up your important files to another partition, or better yet, to a removable drive.

Customizing the browser home page

Sat, 15 Jan 2022 00:00:00 +0000

Greetings!

In this post I’ll tell and show you how you can customize the browser’s home page.

I’ll be showing this using the Firefox browser as an example, but the tool I’m using (the browser extension Tabliss) is also available for Chrome and its derivatives (Yandex browser, Microsoft Edge, Opera, etc.). I haven’t tested those, but I’m sure everything will work similarly.

Try Linux Right Inside Windows

Wed, 15 Dec 2021 00:00:00 +0000

Greetings!

Today I’ll tell and show you how you can try Linux right inside Windows. To do this, we’ll need to take a few steps, the hardest of which will be entering the UEFI/BIOS.

To run another operating system inside the current one, the so-called virtualization technology is used, hardware support for which is implemented in practically every more or less modern processor. Whether it’s a solution from AMD (AMD-V) or Intel (Intel VT). You can read more about virtualization, as usual, on Wikipedia.
