Step 1: Download Your OpenVPN Configuration File

Navigate to the Access section on TryHackMe. From there, click the “Download My Configuration File” button to get your unique .ovpn file.

This file allows your system to securely connect to TryHackMe’s network.

Step 2: Install OpenVPN (Linux)

To install OpenVPN on a Debian/Ubuntu-based system, open your terminal and run:

sudo apt update && sudo apt install openvpn -y

✅ You may need to enter your password to authorize the installation.

Step 3: Connect Using OpenVPN

In your terminal, execute the following command:

sudo openvpn yourfilename.ovpn

Replace yourfilename.ovpn with the actual name of your config file.

Once the connection is established, you’ll see the message “Initialization Sequence Completed” in your terminal.

This means you’re successfully connected to the TryHackMe VPN network.

SStep 4: Confirm VPN Connectivity

To verify your connection, type:

ifconfig

You should see a tun0 adapter listed. This confirms that your VPN is active and functioning correctly.

Step 5: Deploy a Machine on TryHackMe

Head back to TryHackMe and deploy a machine in any room that requires VPN access.

Once deployed, TryHackMe will assign an IP address to the machine:

Note: You might receive a different IP address each time you deploy a machine.

Step 6: Access the Deployed Machine

Use tools like ping, nmap, or netcat, or access web-based services using:

firefox http://<ip-address>

Replace <ip-address> with the one assigned by TryHackMe..

You should be able to access the machine’s web interface if everything was configured properly.

Congratulations – you’ve completed the OpenVPN setup challenge on TryHackMe!
