Debian, also known as “the universal operating system”, is one of the oldest Linux distributions. At any point in time there are always three main Debian releases: stable, testing and unstable. The “stable” release represents the official Debian release: it is rock solid, ready for production, and contains packages which doesn’t change much. The “testing” release contains packages which are on their road to be accepted into stable, and finally, the “unstable” release is the one with the most updated versions of software, used for the distribution development.
How to skip the installation of rpm weak dependencies
RPM is the acronym for Red Hat Package Manager: we use it to reference both the software package format and the low-level package manager used by the Red Hat family of distributions. Since version 4.12 of the latter it is possible to declare packages “weak dependencies”, which are installed by default, but not strictly required.
How to locate and set JAVA home directory on Linux
The Java home directory is the installation directory for the Java Runtime Environment and Java Development Kit (see: Java JDK vs JRE. This directory contains all of the files that come with Java and are used to run Java programs or compile them. The location for this directory can change depending on your system (Linux, MacOS, Windows, etc.) and the version of Java that you have installed.
How to create a custom Fedora live image with Lorax
Fedora is one of the most popular Linux distributions: it is sponsored by Red Hat, but its development is community-driven. While the default version of Fedora ships with the GNOME desktop environment (it is probably the ideal choice if you want to use a vanilla version of the latter), there are many alternative spins available, which allows us to try a variety of desktop environments such as XFCE or KDE Plasma. In few easy steps it is even possible to build and try a custom Fedora live image.
How to show software/package installation date
In case you are wondering when a software package was installed on your Linux system, the information is stored by the package manager and can be accessed via the command line. This can come in handy for a number of reasons, such as when troubleshooting issues that started on a certain date, to see if any packages installed at that time could be causing the problem. In this tutorial, you will learn how to show the installation date for a software package on all major Linux distributions.
How to kill process by port
Processes that utilize the network connection of your Linux system will occupy a port whenever they are uploading or downloading data, or listening for incoming connections. A common example present on many Linux servers would be the SSH protocol, which listens for and accepts incoming connections on port 22 by default. Ordinarily, administrators can kill a process using the PID number, or by specifying the process name. But in some cases, we may want to kill a process according to which port number it is using.
Getting started with Toolbx
Fedora Silverblue is an immutable variant of Fedora Workstation: every installation of this distribution is identical to the others, which is ideal for testing and predictability. On Fedora Silverblue, flatpaks are used as the primary method of installing software together with rpm-ostree which basically creates an additional layer over the immutable filesystem each time an rpm is installed. The toolbx utility is included in Fedora Silverblue as a way to create isolated, mutable environments using podman and the containers technology, allowing the user to install development tools and libraries without touching the main system. Toolbx can be used also on regular Fedora versions.
How to convert JPG to PDF
PDF documents are used for just about anything these days, and are usually considered to be a very professional way to send important data such as contracts or terms for businesses and other formal entities. If you have a JPG image – perhaps the scan of a signed document, for example – you can convert this to a PDF document, which would be a more formal file extension to use for such a matter. In this tutorial, you will learn how to convert a JPG image to a PDF document on a Linux system via command line and GUI.
Linux IP forwarding – How to Disable/Enable using net.ipv4.ip_forward
It may be necessary to configure Linux IP forwarding on a Linux system in certain scenarios. If the Linux server is acting as a firewall, router, or NAT device, it will need to be capable of forwarding packets that are meant for other destinations (other than itself). Linux uses the net.ipv4.ip_forward kernel variable to toggle this setting on or off.
How to check NVIDIA driver version on your Linux system
The objective of this tutorial is to show how to check the NVIDIA driver version installed on your Linux system. There are few places you may have a look to check what NVIDIA driver you have installed on your Linux system. This will allow you to check that you have the latest version installed and optionally upgrade to a new NVIDIA driver for better support and features.
How to setup GNOME using Ansible
GNOME (GNU Network Object Model Environment) is probably the most used graphical environment in the Linux ecosystem, if only because all major Linux distributions such as Fedora, RHEL, Debian and Ubuntu ship with it as the default desktop. GNOME strives for simplicity and ease of use, and for this reason, not without some criticisms by a part of the Linux community, tends to be less customizable than other desktop environments such as KDE Plasma or XFCE. Instead of using plaintext configuration files, GNOME stores its settings in the dconf database, which can be manipulated using the “dconf-editor” GUI, or from the command line using the “dconf” utility.
How to deploy a self-hosted Vaultwarden instance
Everyone, nowadays, has several accounts and credentials to take care of, that’s why everyone needs a decent and possibly open source password manager. When it comes to managing passwords there are many choices available on Linux: in the past, for example we talked about “pass”, a great, command line oriented, password-manager based on standard tools such as GPG and git. In this article we explore an alternative which can be the ideal solution for individuals and small organizations: Vaultwarden.
