How to Set Up a Secure VPN on Windows Server 2019

on

Setting up a Virtual Private Network (VPN) on a Windows Server 2019 is crucial for businesses seeking secure remote access and data protection. This tutorial guides you through the steps to configure a VPN using the Routing and Remote Access Service (RRAS) in Windows Server 2019, ensuring secure communication over the internet.

Step 1: Install the Routing and Remote Access Role

Begin by logging into your Windows Server 2019. Open the 'Server Manager' dashboard, navigate to 'Manage' and select 'Add Roles and Features'. Follow the wizard until you reach the 'Roles' page. Check the 'Remote Access' role and then proceed to 'Features'. Here, ensure 'Routing' is selected, then continue and complete the installation.

Step 2: Configure RRAS

Once the role installation is complete, go back to the 'Server Manager'. Under 'Tools', select 'Routing and Remote Access'. Right-click your server’s name and choose 'Configure and Enable Routing and Remote Access'. Opt for 'Custom configuration', select 'VPN access', and finish the configuration wizard. Restart the RRAS service to apply changes.

Step 3: Configure Authentication and Network Policies

Authentication is a key element in VPN security. Navigate to the 'Routing and Remote Access' console, right-click on your server, and select 'Properties'. Go to the 'Security' tab, choose 'Authentication provider' as 'RADIUS Authentication', and set up your RADIUS server if required. Next, under the 'Policies' node, define new network policies that suit your organization's security requirements.

Step 4: Set Up User Accounts and Permissions

User management is essential for maintaining VPN security. In the 'Computer Management' window, under 'Local Users and Groups', set up user accounts that will have VPN access. Assign permissions and set password policies to enhance security. It’s also advisable to create user groups for better management and scalability.

Step 5: Configure Client Computers

On each client computer that will connect to the VPN, set up a VPN connection in the 'Network & Internet' settings. Use the public IP address or domain name of your Windows Server as the server name or address. Ensure that the VPN type matches the settings specified on your server and enter the necessary credentials.

To finalize, it's important to test the VPN connection from a client computer to ensure everything is functioning correctly. Verify that the network resources accessible via the VPN are working as expected without compromising security.

By following these detailed steps, you can set up a robust and secure VPN on Windows Server 2019, enhancing your organization's network security and remote access capabilities.

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 ...
