Introduction to LVM thin provisioning
LVM (Logical Volume Manager) is a technology which allow us to create a layer of abstraction over physical storage devices, and implement flexible partitioning schemes where logical volumes are easier to shrink, enlarge or remove than classical “bare” partitions. While LVM “thick” provisioning requires the allocation of a fixed amount of storage space to a LVM logical volume at creation time, by using “thin” provisioning, storage is allocated only when needed.
Introduction to the Proxmox backup server: the web interface
Proxmox backup server is an enterprise-level solution to backup containers, virtual machines and physical hosts. In the first part of this series, we learned how to download and install the distribution. Although the system can be managed from the command line, just like any other Linux distribution, it comes also with a user-friendly, integrated web interface.
Configuring NTP on Ubuntu 24.04
Maintaining accurate system time is crucial for various network operations and synchronization tasks. In Ubuntu 24.04, setting up the Network Time Protocol (NTP) ensures your system clock remains synchronized with internet time servers. This guide provides a detailed walkthrough on configuring NTP on Ubuntu 24.04, ensuring your system’s timekeeping is precise and reliable.
Personalizing Keyboard Layouts in Linux
A keyboard has to be the most essential peripheral of any computer system. In order to make sure it works as intended, the correct keyboard layout must be loaded on the Linux operating system, so that the keys on your keyboard will correspond to the letters or symbols that are being typed on screen. This is why it is so important to personalize the keyboard layout of your system to work with your keyboard model. In addition, we can configure custom keyboard settings which makes life a little easier.
Introduction to Proxmox backup server
Proxmox backup server is a free and open source, enterprise-level backup solution. It is implemented as a dedicated Linux distribution based on Debian, and supports essential features like deduplication and encryption. We can use it as a solution to back up and restore virtual machines, containers and physical hosts.
How to Disable IPv6 on Ubuntu 24.04
Ubuntu 24.04, like its predecessors, supports IPv6 by default. However, there are times when you might need to disable IPv6, whether for compatibility reasons, testing purposes, or specific network requirements. This comprehensive guide will walk you through the steps to check if IPv6 is enabled on your system, how to disable it, and how to verify that it has been disabled.
Raspberry Pi vs Arduino: Which is Best for Your Project?
When it comes to single board computers and do it yourself projects, two of the most popular choices are the Raspberry Pi and Arduino. Both of these devices have their own unique advantages, and picking the right one for your project can make a big difference. In this tutorial, we will go over the Raspberry Pi and Arduino in fine detail, highlighting their pros and cons, and helping to guide you on making a decision between these single board computers for your project and its specific needs.
How to use curl to get public IP address
The curl command on Linux systems is commonly used to download and upload files to or from a remote server. Another interesting thing we can use it for is to determine the public IP address of our system. To do this, we can use curl to query websites that are configured to do nothing more than return the IP address of whichever system is connecting to it. This is one of the quickest and easiest ways to get your public IP address on the Linux command line. In this tutorial, you will see how to use the curl command to get your system’s public IP address.
Decoding Raspberry Pi: Which OS to Choose?
Users have many choices when it comes to operating systems for the Raspberry Pi. This was not always the case, like when the Raspberry Pi premiered over a decade ago, support for the device was quite limited. These days, many different Linux distributions have added support for ARM devices like the Raspberry Pi, and there are even a good number of Linux distributions that have been developed specifically for use on the Raspberry Pi.
How to install OpenMediaVault on Raspberry Pi
OpenMediaVault is software that transforms your computer into a NAS (network attached storage) server. Since it features support for the Raspberry Pi, it has become a popular choice for users that are looking to run a lightweight and inexpensive NAS operation. OpenMediaVault comes with a lot of the software and features you will need in order to manage multiple storage disks and share them out to other devices on your local network or even over the internet.
Change IP address on Ubuntu Server
You have two options when configuring the IP address on your Ubuntu Server, and that is either a static IP address or DHCP. A static IP address allows you to manually select your IP address by configuring it on the Linux system, whereas DHCP relies on the router or DHCP server to lease you an IP address – either a reserved one or the next available one that is currently free, depending on the setup.
