How to Set Up a Secure VPN on Windows Server 2022

on

Introduction

Setting up a Virtual Private Network (VPN) on Windows Server 2022 can enhance your network's security by encrypting data and providing remote employees secure access to your company's network. This tutorial will guide you through the process of installing and configuring a VPN using Windows Server 2022’s built-in roles and features.

Step 1: Installing the Remote Access Role

First, you need to install the Remote Access role. Log into your server and open the Server Manager dashboard. Click on 'Add roles and features' and proceed through the wizard until you reach the 'Roles' screen. Here, select 'Remote Access' and then 'Next'. On the 'Role Services' page, check 'DirectAccess and VPN (RAS)' and also select 'Routing'. Continue with the installation and click 'Finish' once completed.

Step 2: Configuring the VPN Service

After installing the necessary role, open the 'Routing and Remote Access' console from the Tools menu in Server Manager. Right-click your server’s name and select 'Configure and Enable Routing and Remote Access'. Choose 'Custom configuration', then select 'VPN access'. Follow the wizard to completion and start the service.

Next, you need to configure your network to allow VPN connections. This involves setting up a new interface for inbound VPN connections. Go back to the 'Routing and Remote Access' console, right-click 'Ports', choose 'Properties', and ensure that there are ports available for SSTP, PPTP, and L2TP. This configuration depends on which protocols you intend to use for your VPN.

Step 3: Configuring User Access

VPN users need permission to connect remotely. Go to the 'Active Directory Users and Computers' console, and find the user account you want to grant VPN access to. Right-click the account, select 'Properties', and navigate to the 'Dial-in' tab. Here, check 'Allow access' under 'Network Access Permission'. This step is crucial for enabling individual user access.

Step 4: Setting Up Firewall and Security

Security is a critical aspect of VPN services. Make sure your firewall settings are configured to allow VPN traffic. Typically, you need to allow traffic on port 1723 for PPTP or port 500/4500 for L2TP over IPsec. Also, ensure that your VPN server has a static IP address to avoid connection issues.

Additionally, consider integrating additional security measures such as SSL certificates for SSTP or using stronger authentication methods like RADIUS or Active Directory instead of simple username-password authentication.

Conclusion

Setting up a VPN on Windows Server 2022 can seem daunting, but following these steps will help you create a secure environment for remote access. Regularly update your server and monitor VPN usage to maintain security and efficiency. With these steps, your organization can benefit from the enhanced security and flexibility that a VPN provides.

Install Ollama and Open WebUI on Ubuntu 24.04 with NVIDIA GPU Acceleration (Step-by-Step)

Overview Running a local large language model (LLM) is easier than ever thanks to Ollama and Open WebUI. Ollama handles model downloads and inference, while Open WebUI gives you a clean, chat-style interface in your browser. In this tutorial, you'll install both on Ubuntu 24.04 (works on 22.04 too), enable NVIDIA GPU acceleration, and deploy them with Docker Compose. The result is a fast, private AI stack you control. What You'll Need - Ubuntu 24.04 or 22.04 (fresh or existing server/desktop). - An NVIDIA GPU with recent drivers (Turing/RTX or newer recommended). - Root or sudo access. - Open ports 3000 (Open WebUI) and 11434 (Ollama) on your firewall if you access remotely. Step 1: Install NVIDIA Drivers and Verify CUDA First, update your system and install the recommended NVIDIA driver. On Ubuntu Desktop you can use Additional Drivers, but the CLI route is reliable: sudo apt update && sudo apt -y upgrade sudo ubuntu-drivers autoinstall sudo reboot After reboo...

Install Ollama + Open WebUI on Ubuntu 24.04 with NVIDIA GPU Acceleration (Step-by-Step)

Overview This guide shows you how to install Ollama and Open WebUI on Ubuntu 24.04 with NVIDIA GPU acceleration. You will get a fast local AI stack that can run modern large language models (LLMs) like Llama 3 on your own hardware, secured and accessible in a web browser. We will cover GPU driver setup, Docker with the NVIDIA Container Toolkit, Ollama installation, Open WebUI deployment, basic security, and troubleshooting. Prerequisites - A machine running Ubuntu 24.04 (fresh or updated). - An NVIDIA GPU with at least 8 GB VRAM recommended for 8B models (more is better). - Internet access and sudo privileges. Step 1: Install the NVIDIA GPU Driver Install the recommended proprietary driver so CUDA becomes available to both Ollama and containers. sudo apt update && sudo apt install -y ubuntu-drivers-common sudo ubuntu-drivers autoinstall sudo reboot After reboot, verify the GPU is recognized: nvidia-smi You should see a driver version and your GPU model. If not, check...

Install a Local AI Chatbot on Ubuntu 24.04 with Ollama and Open WebUI (Step-by-Step)

Running a fast, private AI chatbot on your own computer or server is easier than ever. In this guide, you will install Ollama (a lightweight local LLM runtime) and Open WebUI (a modern web interface) on Ubuntu 24.04 . You will be able to chat with models like Llama 3 or Mistral without sending data to the cloud, and with optional GPU acceleration if you have an NVIDIA card. What you will need : an Ubuntu 22.04/24.04 machine (VM, bare metal, or WSL), at least 8 GB RAM (16 GB recommended for larger models), 15–30 GB free disk space for models, Internet access, and optional NVIDIA GPU drivers for acceleration. Why Ollama + Open WebUI? Ollama manages local large language models (LLMs) with simple commands and sensible defaults. Open WebUI gives you a clean, chat-style interface with features like prompt history, file uploads (for some models), and model switching. Together, they are a simple, reliable stack for a self-hosted AI experience. 1) Update Ubuntu and install basics First, ...

Recovering from Btrfs Boot Failures Using GUI Tools on Fedora

on
By the end of this guide the reader will be able to identify a Btrfs‑based Fedora installation, boot from a live USB, list and restore snapshots using the graphical utilities btrfs‑assistant and snapper, and verify that the system returns to a functional state without resorting to the command line. Understanding the Btrfs Layout Used by Fedora Fedora Workstation and Fedora KDE install the root filesystem as a single Btrfs partition that contains two default sub‑volumes. One sub‑volume holds the traditional “/” hierarchy, while the second is dedicated to /var/lib/machines . The latter exists to keep container images out of snapshot operations; it remains empty on systems that do not run virtual machines. Because Btrfs stores data in sub‑volumes rather than separate partitions, a snapshot captures the state of an entire sub‑volume at a point in time. The installer (Anaconda) automatically registers these sub‑volumes with the snapper service. Snapper maintains a series of read‑only ...
