You can use Ubuntu configuration files from https://www.cactusvpn.com/downloads/ to setup OpenVPN.

How to setup OpenVPN client for CactusVPN:

1. Update configuration files.
2. Start OpenVPN as /etc/init.d/openvpn start or make it start at boot as /etc/init.d/openvpn enable.

You can also start OpenVPN client manually as follows:
