Requirements and preparation
To follow the steps in this How-to, the following requirements must be met. Please see the corresponding documentation if you need help with any of these:
- OpenVPN is installed
- You have root access to your computer
- You have a valid Perfect Privacy account
- You have downloaded the Perfect Privacy configuration and added the files to /etc/openvpn
#!/bin/bash # # This script can be used as an up and down script for OpenVPN. # It adds and removes the routes required for a VPN connection # cascaded over multiple Perfect Privacy VPN servers.
Get the script on the left, save the file as updown.sh in you /etc/openvpn/ directory and make it executable with chmod +x /etc/openvpn/updown.sh.
Change into the /etc/openvpn/ directory and issue the following command to establish the connection to the first hop as shown on the left. In this example it will connect to london.perfect-privacy.com:
sudo openvpn --config London.ovpn --script-security 2 --route remote_host --persist-tun --up updown.sh --down updown.sh --route-noexec
After the connection to the first hop has been established, the script will display the necessary command with all parameters to connect to the second hop. You can copy and paste this line but will need to change <config.ovpn> for the corresponsing configuration file of the server for the next hop.
Now open a new terminal and paste the connection line displayed by the script. Before you press enter, make sure that you replace <config.ovpn> with the location you want to connect to. In this example the second hop is Rotterdam.perfect-privacy.com.
To add a third hop, repeat the previous steps in a new terminal window. In this example we’re continuing the cascade with Reykjavik.perfect-privacy.com.
If you want, you can add even more hops by repeating the pervious steps once more.
