  • Linux 101: How to copy files and directories from the command line

    Are you new to Linux? If so, you've probably found the command line can be a bit intimidating. Don't worry--it is for everyone at the beginning. That's why I'm here to guide you through the process, and today I'm going to show you how to copy files and folders from the command line.

    Why would you need to copy files and folders this way? You might find yourself on a GUI-less Linux server and need to make a backup of a configuration file or copy a data directory.

    Trust me, at some point you're going to need to be able to do this. Let's find out how.

  • How to install Headless Dropbox on Ubuntu Server

    Dropbox can be termed as cloud-based file storage that makes your files available at any given time as long as you are connected to the internet. A local user accesses files by syncing to Dropbox. This aids to automatically update all removed and added files to your cloud-based storage. Most people are curious to know how the headless Dropbox can be installed on an Ubuntu Server. To learn more, follow the article below for detailed information, including screenshots of how the installation process is done.

  • Masterby Books by Michael W Lucas

    Look what was delievered a few days ago! Can’t wait to skill up in both SUDO and PAM modules.

    Michael W Lucas has written dozens of technical books on some of the most fascinating aspects of systems administration - I’ve read SSH Mastery book in the past and will someday try using FreeBSD for real just because Michael wrote so many books about this wonderful OS.

  • Cloud Native Patterns: a free ebook for developers

    Building cloud native applications is a challenging undertaking, especially considering the rapid evolution of cloud native computing. But it’s also very liberating and rewarding. You can develop new patterns and practices where the limitations of hardware dependent models, geography, and size no longer exist. This approach to technology can make cloud application developers more agile and efficient, even as it reduces deployment costs and increases independence from cloud service providers.

  • How to Install and Use the Etcher Tool on Ubuntu

    In most cases, when we’re trying out a new OS, we choose to install it on the main machine, a virtual machine, or to boot alongside another operating system.
    One of the upsides to using a Linux system is that we can boot using Live media, which makes it possible to test a specific distribution without altering the primary structure. Using bootable media such as USB drives, we can burn an iso image and boot from it or even use it to install the OS.

    Although there are various ways to create bootable media—UnetBootIn, dd (Unix), Rufus, Disk Utility, etcetera, —having a simple and cross-platform tool can be massively advantageous.

  • What is the difference between Paramiko and Netmiko?

    When it comes to networking, there is a wide range of perspectives, and one cannot master how to interact with all the devices in the real world. However, all networking devices share similar functionality that, when mastered, are automatable.

    As mentioned in my other tutorials, programmers are lazy and always looking to improve efficiency—thus doing the least work —, and when it comes to automating network-related issues, many often jump at the chance.

    In today’s quick guide, I’ll introduce you to automating SSH using two popular Python libraries: Paramiko and Netmiko. We will create simple python scripts using the two libraries to automate SSH and interact with network devices.

    I choose this approach because a guide primarily focused on the differences between Paramiko and Netmiko would be too short—a simple table would suffice—and no-concrete. By taking this approach, you’ll be better able to experiment with them and see which does what and how.

  • How to Use Unison to Synchronize Files Between Servers

    This tutorial will show you how to set up and use the Unison File synchronization tool on Debian systems. Using Unison, you can sync files between two different disks or directories in the same system or two other systems over the network.

  • How to detect the file system type of an unmounted device on Linux

    If you want to store data on a new hard drive or a USB memory stick, what you first need to do is to create a "filesystem" on it. This step is also known as "formating" the drive or the USB stick. A filesystem determines in exactly what format data is organized, stored and accessed on a physical device. It is often necessary to know the type of filesystem created on a hard disk or a USB thumb drive even before mounting it. For example, you may need to explicitly specify filesystem type when mounting a disk device, or have to use a filesystem-specific mount command (e.g., mount.aufs, mount.ntfs).

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • 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.
