  • How to use etckeeper to manage /etc in OpenSUSE Leap 15

    Etckeeper is a simple, easy-to-use, modular and configurable collection of tools to let /etc be managed using version control. It allows the contents of /etc to be stored in a Version Control System (VCS) repository such as git. Thus allowing you to use git to review or revert changes that were made to /etc, in case of a mistake.

    In Linux/Unix, the /etc directory is where host-specific system-wide configuration files and directories are located; it is a central location for all system-wide configuration files. A configuration file is a local file used to control how a program works – it must be static and cannot be an executable binary.

    To keep track of changes to system configuration files, system administrators normally make copies (or backups) of configuration files before modifying them. That way if they directly modified the original file and made a mistake, they can revert to the saved copy.

    In this guide, we will learn how to Install and configure etckeeper in Opensuse Leap 15.

  • Install NotePad++ on Ubuntu 22.04 LTS Linux using SNAP - Linux Shout

    Learn the simple steps to install NotePad++ on Ubuntu 22.04 LTS Jammy JellyFish Linux using the command terminal for writing programs.

    Free Notepad++ is based on the Windows Notepad Editor but functionally for writing programs. Therefore, we cannot install Notepad++ on the Linux system simply using its package manager such as APT. In such a situation, we have to take the help of Wine – a free and open-source compatibility layer to run Windows applications.

    On one hand, notepad.exe on Windows is suitable for making short notes, the Notepad++ program goes beyond. Any person who writes code would already know about this app. It offers functions such as syntax highlighting, which highlights certain entered code blocks in color. This improves the overview.

    In addition to TXT, there are entries for Batch, C++, C#, JavaScript, PHP, PostScript, Windows PowerShell, Python, R, the Windows Registry (*.reg), Ruby, Swift, and Visual Basic. Users just need knowledge of the programming languages, Notepad++ makes things easier, but does not take away your know-how here.

  • How to Use RSYNC to Backup Data on Ubuntu – OSNote

    Loss of valuable data and not being able to recover it is the most painful incident that can happen to any of us. To take precautions against this problem, a backup copy of the data needs to be created. A data backup is a copy of valuable data kept on your devices, such as computers, phones, or tablets, that is used to recover the valuable data that has been lost. Data loss is caused in a variety of ways, including failure of hard drives, ransomware, and even human error. Whatever the disaster, a backup of data could provide the relief you need to restore the data on your devices. It’s usually kept in a safe, different location from the original device, such as the cloud. One of the approaches we use in Linux to back up our data is using “rsync”. In this article on Ubuntu 20.04, we use the rsync approach to back up data.

  • Neat uses for a backlit keyboard

    I bought myself a new keyboard last November, a Logitech G213. True keyboard fans will tell me it’s not a real mechanical keyboard, but it was a lot cheaper and met my requirements of having some backlighting and a few media keys (really all I use are the volume control keys). Oh, and being a proper UK layout.

    While the G213 isn’t fully independent RGB per key it does have a set of zones that can be controlled. Also this has been reverse engineered, so there are tools to do this under Linux. All I really wanted was some basic backlighting to make things a bit nicer in the evenings, but with the ability to control colour I felt I should put it to good use.

  • Scan for SSH private keys without passphrase | Ganneff’s Little Blog

    So for policy reasons, customer wanted to ensure that every SSH private key in use by a human on their systems has a passphrase set. And asked us to make sure this is the case.

    There is no way in SSH to check this during connection, so client side needs to be looked at. Which means looking at actual files on the system.

    Turns out there are multiple formats for the private keys - and I really do not want to implement something able to deal with that on my own.

  • How to Install and Configure Puppet 7 Server on Ubuntu 20.04

    In this guide, we are going to install Puppet 7 Server Open Source in Ubuntu 20.04. We will set up a Puppet server and an agent and install Nginx using puppet manifests.

    Puppet is a software configuration management tool which includes its own declarative language to describe system configuration. It is a model-driven solution that requires limited programming knowledge to use. Puppet operates in an agent-master architecture, in which a master node controls configuration information for a fleet of managed agent nodes.

    Puppet is distributed in several packages. These include puppetserver, puppet-agent and puppetdb. Puppet Server controls the configuration information for one or more managed agent nodes. PuppetDB is where the data generated by Puppet is stored.

  • 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.
