How to Set Up a Secure VPN on Windows Server 2019

on

Introduction

Setting up a Virtual Private Network (VPN) on Windows Server 2019 is essential for businesses seeking to secure their data communications and provide remote access to their network. This tutorial will guide you through the process of installing and configuring a VPN using Routing and Remote Access Service (RRAS) in Windows Server 2019.

Step 1: Install the RRAS Role

First, you need to install the RRAS role. Open the 'Server Manager', click on 'Manage', and then choose 'Add Roles and Features'. Proceed to the 'Roles' section and select 'Remote Access'. Then, in the 'Role Services' section of the installation wizard, check 'Routing' and 'Remote Access Services' > 'DirectAccess and VPN (RAS)'. Click 'Next' and then 'Install' to add these features to your server.

Step 2: Configure RRAS

After installation, open 'Routing and Remote Access' from the 'Tools' menu in 'Server Manager'. Right-click your server and select 'Configure and Enable Routing and Remote Access'. In the wizard that appears, choose 'Custom Configuration', then select 'VPN access', and follow the prompts to complete the configuration. Restart the RRAS service to apply changes.

Step 3: Configure Authentication and Network Policies

For security, it's crucial to configure authentication methods. Go to the RRAS console, right-click your server, and choose 'Properties'. Navigate to the 'Security' tab and click 'Authentication Methods'. Here, you can enable Microsoft CHAP Version 2 (MS-CHAP v2) for encryption. Next, configure network policies in the 'Network Policy Server' under 'Policies'. Ensure you specify conditions and settings that align with your security requirements.

Step 4: Set Up VPN Users

In 'Server Manager', go to 'Tools' > 'Computer Management' and navigate to 'Local Users and Groups'. Here, you can create new users or configure existing ones to access the VPN. Right-click 'Users', select 'New User', and fill in the details. Ensure each user has a strong password. After creating users, ensure they have permission to connect to the VPN via their user properties under the 'Dial-in' tab.

Step 5: Configure Client Machines

To connect to the VPN from client machines, configure the VPN client settings on each machine. Go to 'Network Settings' > 'VPN' and click 'Add a VPN connection'. Use 'Windows (built-in)' for the VPN provider, input the server's name or IP address, and select 'Secure Socket Tunneling Protocol (SSTP)' as the VPN type. Enter login credentials and connect to the server using the established VPN connection.

Conclusion

Setting up a VPN on Windows Server 2019 enhances your network's security and allows remote access to your resources. By following these steps, you can ensure that your VPN is properly configured for secure and efficient operation. Remember to regularly update your system and check the security settings to maintain optimal protection.

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 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, ...

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.

Homogeneous Nucleation on Mars: A Textbook Process Finally Observed in Nature

By the end of this piece, you will understand what the Arsia Mons Elongated Cloud is, why it resisted explanation for several years after its first observation, and what the newly published model reveals about a physical process that has never been directly confirmed on any planet's atmosphere. The cloud that broke the model Every morning during Martian spring and summer, a thin, extremely long cloud forms near the Arsia Mons volcano and gradually elongates until it stretches to more than 1,000 miles before dissipating. The cycle then repeats for several months. The formation was first recorded by a probe in 2018, and from that point onward it became a persistent puzzle for atmospheric scientists working with Mars data. The cloud's geometry, its timing, and its seasonal recurrence all pointed to a real and reproducible physical process, yet no existing model could reproduce it. For a technical audience familiar with simulation work, the situation is analogous to a product...
