== Using Algo VPN to Access SDNOG Infrastructure ==

=== Introduction ===
Algo VPN is a tool that simplifies the process of setting up a secure VPN server on various platforms. This guide will walk you through the steps to install and configure Algo VPN on a local Ubuntu server to access SDNOG infrastructure.

=== Prerequisites ===

* An Ubuntu server (18.04 or later)
* Sudo privileges on the server
* Basic knowledge of command-line operations
=== Step-by-Step Guide ===

==== 1. Update Your System ====
Before installing Algo VPN, ensure that your system is up-to-date. Open a terminal and run the following commands:
<pre>
sudo apt update
sudo apt upgrade -y
</pre>
==== 2. Install Dependencies ====
Algo VPN requires certain dependencies to be installed. Use the following commands to install them:
<pre>
apt-get install git apparmor build-essential python3-dev python3-pip python3-setuptools python3-virtualenv libffi-dev libssl-dev -y
</pre>
==== 3. Clone the Algo VPN Repository ====
Clone the Algo VPN repository from GitHub to your local server:
<pre>
git clone https://github.com/trailofbits/algo.git
cd algo
</pre>
==== 4. Create and Activate a Python Virtual Environment ====
Create a Python virtual environment and activate it:
<pre>
cd algo
python3 -m virtualenv --python=/usr/bin/python3 .env
</pre>
==== 5. Install Algo VPN ====
Install Algo VPN and its dependencies using pip:
<pre>
python3 -m pip install -U pip virtualenv
python3 -m pip install -r requirements.txt
</pre>

==== 6. Configure Algo VPN ====
Run the Algo VPN setup script to create a configuration file:
<pre>
./algo
</pre>
Follow the prompts to configure your VPN. You will need to provide details such as:

The VPN server's public IP address or domain name
Your preferred VPN protocol (e.g., WireGuard or IPsec)
User accounts for VPN access

==== 7. Deploy Algo VPN ====

Once the configuration is complete, deploy Algo VPN with the following command:
<pre>
./algo
</pre>
The deployment process will set up the VPN server according to the configuration you provided.

==== 8. Access SDNOG Infrastructure ====
To access SDNOG infrastructure via the VPN, you need to configure your local machine to connect to the VPN server. Download the VPN client configuration files from the Algo VPN setup and import them into your VPN client.

For WireGuard, you can use the wg-quick tool to connect:
<pre>
sudo wg-quick up /path/to/your/configuration.conf
</pre>
For IPsec, follow the instructions specific to your operating system to import the configuration and connect.

=== Troubleshooting ===
If you encounter issues during installation or configuration:

Check the Algo VPN documentation for troubleshooting tips.
Ensure that your firewall rules allow VPN traffic.
Verify that your VPN client is correctly configured.
=== Conclusion ===
By following these steps, you should have a functioning Algo VPN setup on your local Ubuntu server, providing secure access to the SDNOG infrastructure. For more advanced configurations and additional features, refer to the Algo VPN GitHub repository.
