It’s a simple process. I followed the steps outline in the free room at TryHackMe called OpenVPN. Here is how I connected to TryHackMe’s servers through Linux:

Go to TryHackMe’s access page.

Download the configuration file from the server closest to you. E.g., I’m in Canada, so I picked the only US server available.

Install OpenVPN

sudo apt install openvpn

Run the config file that you downloaded

sudo openvpn [filename.ovpn]

Refresh the access page and confirm you’re connected with a green checkmark under OpenVPN Access Details.

Then verify you’re connected by starting a TryHackMe machine and punching the machine’s IP address into your web browser. If successful, you’ll get a happy response from OpenVPN.

To start the service again, just run that second bit of code.
