> In this tutorial, we will show you how to install FreeRADIUS on Ubuntu 22.04 LTS. In the rapidly evolving landscape of technology, network security is of paramount importance. To safeguard sensitive information and ensure secure access to resources, organizations need robust authentication and authorization systems.
> VirtualBox, a powerful open-source software, allows you to run nearly any operating system (OS) on a single machine without the need for dual booting or partitioning. One such OS that you can run within VirtualBox is CentOS Stream, an innovative platform that serves as the upstream (development) branch of Red Hat Enterprise Linux (RHEL). It is designed for developers who need a rolling-release distribution to stay on the cutting edge of Enterprise Linux development.
> In this comprehensive article, you will learn what Snap is in Linux, discovering its remarkable features, intriguing history, and the controversies that surround it.
> In Linux systems, including Debian 12, the sudo group grants users the ability to execute administrative commands. This provides them with the privileges to install, update, and delete software, modify system configurations, and more.
> Administrative permissions are vital for maintaining and controlling the operating system. They allow you to perform tasks that regular users cannot, ensuring security and overall system health.
> This article is intended for system administrators, advanced users, or anyone responsible for managing Debian 12 systems.
> Learn how to run specific commands without sudo password in Linux. Understand the benefits, risks, and best practices for secure implementation.
> Tailscale is a lightweight, yet powerful decentralized Virtual Private Network (VPN) service. It allows you to connect multiple devices across different connections in a single logical network. As a result, you can use Tailscale to host any local service across the internet without forwarding any ports.
> This article will show you how you can set up Tailscale and route traffic between two Ubuntu Linux machines.
> You don't need a powerful computer system to use AI. We show what it takes to benefit from AI on the Raspberry Pi and what tasks the small computer can handle.
> When I run apt update on my Ubuntu laptop it prints a stream of errors about W: target packages/repos/DEP-11 being ‘configured multiple times’. These errors do not prevent apt from working (so it’s not an issue in that sense) but the lengthy printout looks messy, is annoying to see, and clearly (since I’m being told about it) is something I should fix.
> Imagine a city buzzing with life, a web of highways humming with vehicles during peak rush hour. Without warning, an urgent call reverberates through the air: “Everyone stop what you’re doing! We have to fix a pothole!”
> In this tutorial, we will show you how to install Django on Debian 12. For those of you who didn’t know, Django, a powerful Python web framework, empowers developers to build dynamic and sophisticated web applications with ease.
> If you don't want to receive updates for a software that is not installed on your system anymore, you need to remove its repository from your system.
> To remove a repository on OpenSUSE is quite simple. You can remove a repository by using the terminal, and by using
> Managing the flow of network traffic in and out of a Linux system is vital for maintaining system security. This can be achieved through various tools that are bundled within most Linux distributions, including iptables, UFW (Uncomplicated Firewall), and firewalld.
> Warpinator is a tool that you can use to share files between computers on the same network. It allows you to share files easily without having to upload your files on a third party cloud hosting.
> PHP (Hypertext Preprocessor) is a widely-used scripting language that is especially suited for web development. It's an essential component in a typical LAMP (Linux, Apache, MySQL, and PHP) stack. Knowing your PHP version is critical, especially when installing new software or troubleshooting compatibility issues, as different applications may require specific PHP versions to function correctly.
> Virtualization allows you to run multiple operating systems simultaneously on a single computer, providing an environment for testing, development, and partition-free system upgrades. Two popular software choices for creating virtual machines (VMs) are VirtualBox and VMware Player.
> Secure Shell (SSH) is a protocol used to securely connect to remote systems, and ssh-agent is a crucial part of this process. ssh-agent is a program that holds your private keys used for SSH authentication, providing a secure and convenient method of accessing these keys when connecting to an SSH server.
