  • The Differences between Su, Sudo Su, Sudo -s and Sudo -i - Make Tech Easier

    There are many different ways to get a root session in the Linux terminal. This can create some confusion, as most beginning users who are looking to gain root privileges might not be familiar with how each command can gain root access, how they are different and when these differences matter. Here we take apart each of the many different commands used to gain root access in a terminal, explain how they gain root, when to use them, and everything in between.

  • Looking at your Linux system's network interface with ethtool | Network World

    The ethtool utility on Linux allows you to view and change some of your network-driver and interface-card settings, especially for wired devices. These include their speed, whether the interface uses auto-negotiation, and whether it runs in half- or full-duplex mode. Ethtool also provides an easy way to view or troubleshoot your network interface.

  • Instructions: Encrypt home directories under Linux with Gocryptfs

    Confidential data on notebooks, shared PCs and servers in third-party data centers require special protection – through encryption. This should be done as transparently as possible so that it does not interfere with the usual work. A Linux system completely encrypted with Cryptsetup, for example, protects the contents of the data media from outside parties, but not from other users or the system administrator. Individually encrypted home directories do this. If users log in with their login password, they simultaneously unlock the master key, which only gives access to their personal directory. If you log off again, the files are only available in encrypted form. They cannot be viewed even with root rights.

  • Linux: manage software packages with Bauh

    Package managers are a fine thing: They install all the components of an application in the correct directories, keep the components up-to-date and, if necessary, clean them from the hard drive without leaving any residue. A program can be found and installed quickly using the search function. While packages from the distribution repositories have so far dominated Linux, applications are now also reaching many Linux systems from sources other than Flatpak, Snap or AppImage. The advantages are obvious: libraries and runtime environments are included in the correct version, the programs can be updated independently of the system, are easy to set up and work on most Linux systems.

    While you can set up Snap packages with Ubuntu directly via the software management, applications in Flatpak format are available, for example, via the Flathub repository. AppImages, on the other hand, can often be found directly on the project website of an application. The package manager Bauh offers more direct access: its graphical user interface can be used to conveniently find, install, update, delete and start applications in various package formats. The name Bauh (pronounced Ba-uh) comes from the Brazilian Portuguese and means something like chest or box.

  • 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.

  • 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.
