I followed the steps in this video
https://www.youtube.com/watch?v=QoQ-GS57sQE
I connected to my VPS using putty and ran all of these commands (my VPS is running Ubuntu 18.04)
1. Update the software download lists:
apt-get update
2. Upgrade the software on your server:
apt-get upgrade
3. Download the OpenVPN auto-installer script:
wget
https://raw.githubusercontent.com/Nyr/openvpn-install/master/openvpn-install.sh
4. Make sure the script has the right permissions:
chmod 777 openvpn-install.sh
5. Run the OpenVPN installer script:
bash openvpn-install.sh
all of those steps ends up opening "OpenVPN Roadwarrior installer"
it ask for OpenVPN protocal I selected UDP
I kept the default listening port of 1194
it ask which DNS i would like to use, I choose "google"
I then get to name the OpenVPN Client certificate
and BAM it installs on the sever automatically.
I am able to use FileZilla to connect to the server and grab the OVPN config file and import it into Pritunl (OpenVPN Client) to connect.
Hope this helps
