In the client-server architecture used by the SSH protocol, a client can authenticate by providing a tunneled clear text password or by using a public/private key pair: this is called public key authentication. A user who logs in in via a public key on a remote machine has complete access to the command line; in certain situations, however, it may be useful to associate a public key to a single specific command, for security reasons.

Creating a bootable USB drive is often necessary when you want to install or repair an operating system. This guide provides detailed steps on how to create a bootable USB drive for Windows 10 or 11 using Linux (both Debian and RPM-based distributions).Our handy script does all the heavy lifting, making this task a breeze. The script operates by formatting the USB drive, and then copying the ISO file to the USB drive.

YouTube is home to most of the world’s video content these days. The YouTube website does not give users an easy way to download videos, since its in their best interest that users continually return to the site any time they want to watch a video. However, it is sometimes better to download videos for offline use, so users can archive content that is at risk of disappearing from online, or just so they can continue watching without an internet connection.

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.

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.

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.

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.

In order to have a logical separation for different groups of resources, Kubernetes gives us the namespaces feature. It is also convenient when you have a big environment that is managed by multiple users or teams, and each one needs their own “space” for the resources that they are assigned to manage and administer. This is a much better solution than creating numerous Kubernetes clusters just to facilitate different groups of services or deployments, and to isolate teams to their own space.

In the rapidly evolving world of software development, GitOps has emerged as a game-changing approach, garnering significant attention and adoption across the industry. This paradigm shift seamlessly marries the power of Git, a widely-used version control system, with the principles of DevOps, revolutionizing the way development teams manage and deploy their applications.

Bash script loops are an essential component of any developer’s toolkit for automating repetitive tasks and streamlining workflows.

Flatpaks represent a relative new, cross-distribution way of distributing software on Linux: applications are packaged together with their dependencies and runs in a sandbox, isolated from the rest of the system, except for some specific areas they need to access to work correctly. The system resources a flatpak needs to access are visible when it is installed from the command line; with Flatseal we can inspect and manage them graphically.

ShellCheck is a free and open source static analysis tool which can be used to check and improve shell scripts. It is able to highlight both common and edge-case errors, and suggest the appropriate fixes. ShellCheck can be used as an online or system utility, but can also be integrated as a linter in various text editors.
