Openvpn - How to install Openvpn Access Server on Ubuntu 16.04

Getting Started
Confirm that you have the following before you follow this guide: • 1 Node (Cloud Server or Dedicated Server) running Ubuntu 16. • Root access to the node or one sudo non-root user

Setup
You’ll need to download the latest OpenVPN AS package for Ubuntu 16.04. Packages can be found at https://openvpn.net/index.php/access-server/download-openvpn-as-sw.html.

Having downloaded the correct package, it must now be installed. Here we’ll take care of that.

You’ll want to change the password for the openvpn user so it is unique. Without performing this step, anyone familiar with the default OpenVPN AS password can use your server without authorization. Pick a good password and keep it stored in a secure place.

You can now access the OpenVPN AS interface with the username “openvpn” and the password you just set.

You’ll want to familiarize yourself with OpenVPN AS’ various web interfaces. Start with the administrative UI available at http://your_ip:943/admin.

There is also the client UI, available at http://your_ip:943/.
