Today we're going to go over the use of SSH keys. How to use them, setting them up and why they're preferred! We'll go through creating different keys for different uses, adding public keys to a remote server, setting up an SSH config file for management and more! Helpful reference: Code: GENERATE KEY: ssh-keygen -t ed25519 -C "comment" -f /path/to/key COPY TO SERVER: ssh-copy-id user@server CONFIG FILE (~/.ssh/config): Host nickname HostName server.com User username... https://www.linux.org/threads/how-to-set-up-and-manage-ssh-keys-on-linux.59673/
Now we can continue learning about Python by Binding Keys and Events. If you have not read the previous article, then you definitely need to read it since this article continues and builds on all of it. Some of the following examples may contain material from the first article. Mouse : MouseWheel You need to use the 'MouseWheel' event on objects that can scroll. Let's look at an example where we have a global variable to keep count, called 'counter'. When you turn the wheel while... https://www.linux.org/threads/python-series-part-20-binding-keys-and-events-part-2.57751/
Just recorded/released a new screen tutorial .. check it out, subscribe! There's a lot of reasons to use screen. Mostly it's because you want to make sure you can re-connect to the session that you started on that other server. This video goes over how to use it so you can get your stuff done. https://www.linux.org/threads/screen-video-tutorial.59592/
In following the modularity of Linux, we will look at the Bootloader. A Bootloader is software that the hardware loads the Linux kernel into memory. The system Bootloader is the bridge between the hardware powering up and the Operating System (OS) taking over. NOTE: If you continue with installing any of these Bootloaders, you need to disable Secure Boot in your UEFI settings. There are two folders to be aware of for Bootloaders. The Boot folder is where the actual kernel and... https://www.linux.org/threads/linux...and-configuring-refind-limine-and-grub.57750/
Most systems these days use the Unified Extensible Firmware Interface (UEFI). This is an interface between the hardware on a PC and the Operating System (OS). When the hardware begins, there is firmware that is loaded and starts initializing the hardware. Once the UEFI has initialized the hardware, it then loads the boot manager, and then loads the OS through the boot manager. Examples of Boot Managers are GRUB, rEFInd, Limine and others. The Boot Manager is the same as a Bootloader. There... https://www.linux.org/threads/linux-boot-management-with-efibootmgr.57749/
In the article on Tkinter Buttons, I mentioned binding keys to allow a key press to activate a button. Of course, other widgets have this ability as well. For buttons, we use an ‘underline’ feature to underline a character to show a user can access it with a key press instead of clicking it with the mouse. We can use the key binding process more later when we get to the article on ‘menus’. We will also cover a lengthy list of Events that can occur, because binding keys is creating an... https://www.linux.org/threads/python-series-part-19-binding-keys-and-events-part-1.57438/
Fun bit of Linux history: On Thanksgiving Day 2011, Linus Torvalds released Linux 3.2-rc3 kernel with this delicious recipe: "One quarter arch updates, two quarters drivers, and one quarter random changes. Shake vigorously and serve cold.." He even joked about the timing, saying "And maybe the rest of the world can try to make up for the lack of any expected US participation? Hmm?" while Americans were in their food-induced turkey comas. November has been a significant month in Linux... https://www.linux.org/threads/happy-thanksgiving.59185/

I came across this issue when using VirtualBox. I know you may be thinking that this is something simple. All you need to do is press the HOST key and 'F' for full screen, but this is a completely different way without losing the windowed screen. Personally, I prefer to leave it with the window so I have access to the minimize, restore and close buttons in the top right corner. It also leaves my menu at the top left, while the hardware information is at the bottom right. Somehow, I just... https://www.linux.org/threads/custo...-with-xrandr-virtualbox-friendly-guide.57437/
When Linux boots, it goes though all the stages of booting, loading the kernel, initializing the initramfs and devices, system initialization and target execution to the Operating System (OS) loaded. The Greeter appears to allow the user to log into the OS. The Greeter not shows the prompt to allow the user the ability to enter a username and password, but also lets the user select a Desktop Environment. You can choose the Accessibility options. As we've been going over articles about the... https://www.linux.org/threads/choos...ddm-slim-lightdm-gtk-and-gdm-explained.57436/
I've covered installing Arch Linux on a system, but installing it on VirtualBox is a bit more tricky. Technically, there is only one very important aspect of installing on it on VirtualBox that is different. I have tested this quite a bit for installations and cloning a machine also works well. Download To start, you need the ISO file for the installation. The website is at ‘https://archlinux.org/download/’. Towards the bottom of the page is a listing that is sorted by... https://www.linux.org/threads/installing-arch-linux-in-virtualbox.57435/
In two previous articles, Gentoo OpenRC Installation and Bash 02 – Variables and Such, I mentioned the use of the Prompt String 1, 'PS1', to change the prompt for the Command-Line Interface (CLI). Let's look at this in more detail to get your prompt to be more specific to what you want it to be in the terminal. Configuration... https://www.linux.org/threads/terminal-prompt-customization.57149/
In a previous article, SD Card Basics, I covered the different SD Cards and their abilities. The member 'aeiou' commented that the SD Card Association has an SD Card Formatter for Linux. There is one for Windows and Mac as well, but we'll look at the Linux version. The page for the Formatter is here. Keep in mind that this is a command-line... https://www.linux.org/threads/sd-card-formatter-for-linux.57148/
Everyone who has used a computer or even a phone or tablet know what a button is in a Graphical User Interface (GUI). A button is a clickable object that causes something to happen or start processing. In this article, we can cover buttons on Tkinter. Keep in mind that if you have read the article on Labels, then most of this you should know since most options are the same for almost all widgets. Text The string used for the ‘text’ option is displayed on the button. Let’s look at a... https://www.linux.org/threads/python-series-part-18-working-with-buttons-in-tkinter.57146/
