  • How to Use the Rsync (Remote Sync) Command in Linux with Examples

    talking and exchanging data, establishing communication among themselves in bits, zeros and ones, making up all the great content we get off the internet.

  • Add User to Sudoers in Ubuntu - ByteXD

    In most modern operating systems, there are various levels of authorities a user can have, which governs who have the power to access files on the system.

    The user with the highest authority in Linux operating system is the root user, and as the root user you can do anything to the files in the system (some of those files govern the hardware in turn) from execution to deletion, this power is only limited to the root user to prevent risky actions, or even prevent actions that expose the system to catastrophic consequences (i.e., attacks).

    Sometimes you need to execute a command as the root user (or as another user without logging-out and logging in again!), but in this case you should have the authority to do so! If you can’t that means you are not in the sudo group, neither you are in the sudoers file!, in this article, we are going to explain both ways to grant a user that authority. (Note: sudo is the acronym for Super User DO).

  • Getting Started with Alpine Linux Apk Command Examples

    Every Linux distribution has its package manager that plays a role in the installation and management of software packages. For Debian/Ubuntu we have an apt package manager.

    For RHEL and modern RedHat distributions such as CentOS, Rocky Linux, and AlmaLinux, the package manager is DNF. Of course, we have universal package managers such as snap and flatpak.

    In Alpine Linux, APK, short for Alpine Package Keeper, is the package management tool. It retrieves packages and information about the packages from online repositories.

  • Enable Browsing with DNS Over TLS (DoT) on Ubuntu Made Easy

    Today we increasingly saw the importance of privacy and security in computing. This includes our browsing activity, which now needs protection even more than before. This tutorial will help you enable DNS over TLS (DoT) on Ubuntu using Quad9 service, an alternative technology to DNSCrypt or DoH, that helps preventing anybody to wiretap and/or hijack what website you are visiting on web browser. This feature is already built-in on Ubuntu 22.04 LTS Jammy Jellyfish and we do not need to install additional software.

  • Managing logs with Logrotate on Ubuntu – VITUX

    The performance of a computer or server environment very much depends upon the system memory and disk usage. If something is consuming more disk space then it will lead to a system error. Likewise, increasing log file size must be controlled to reduce such risk.
    Logrotate was introduced as a system utility that rotates, compresses the log files, and mails system logs. Such management of log files reduces disk space usage and prevents system errors.

    In this article, we are going to discuss the installation process and the configuration of logrotate on Ubuntu 20.04 LTS server.

  • Linux Fu: An Odd Use For Fork() | Hackaday

    If you are a Star Trek fan, you’ll probably remember the phrase “You have to learn why things work on a starship.” The truth is, in most episodes, knowing how to override another ship’s console or make gunpowder didn’t come in very handy, but boy when it did, it really saved the day. Linux is a lot like that. There are a few things you probably don’t need to know very often, but when you do need to know, it makes a huge difference. In this particular post, I want to look at an odd use of the fork system call. For many purposes, you’ll never need to know this particular irregular use. But when you need it, you are really going to need it.

    This is actually based on an old client of mine who used Unix to run a massive and very critical report every day. The report had a lot of math since they were trying to optimize something and then generate a lot of reports. In those days, the output of the report was on old green-bar paper on a line printer. The problem was that the report took something like 14 hours to run including the printouts. If someone discovered something wrong, there was no time to run the report again because the next day’s report would have to start before the second run would finish.

  • 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.
