In this tutorial we will show you how to set up OpenVPN 3 Linux, but first let’s see what are our requirements.
In order to set up the OpenVPN you will need:
Open the terminal by hitting CTRL + ALT + T
To become a root user, run:
and input your password.
Ensure that your apt supports the https transport:
apt install apt-transport-https -y
Install the OpenVPN repository key used by the OpenVPN 3 Linux packages:
apt-key add openvpn-repo-pkg-key.pub
Now you need to install the proper repository. Replace $DISTRO with the release name depending on your Debian/Ubuntu distribution.
In my case it is “focal”:
wget -O /etc/apt/sources.list.d/openvpn3.list https://swupdate.openvpn.net/community/openvpn3/repos/openvpn3-$DISTRO.list
Install the OpenVPN 3 package:
apt install openvpn3 -y
Download the OpenVPN configuration files:
wget -O /etc/openvpn3/CactusVPN-OpenVPN-Config.zip https://billing.cactusvpn.com/downloads/openvpn-configs/CactusVPN-OpenVPN-Config.zip
Unzip the OpenVPN configuration files:
Go to /etc/resolv.conf by running:
and add this line:
at the top.
Hit CTRL + o to save the changes and CTRL + x to exit the file.
To connect to a VPN server, we need to know the name of its corresponding configuration file. For example, Nuremberg TCP configuration file name is DE-Nuremberg-CactusVPN-TCP.ovpn.
To connect to Nuremberg TCP, run:
openvpn3 session-start --config DE-Nuremberg-CactusVPN-TCP.ovpn
Type the VPN username and password.
You can find them in your account on our website, by going to Settings. Make sure you use your VPN username and password and NOT the client area credentials (What is the difference?).
After providing the correct credentials you will get the Connected message.
To check if your IP address was changed, run:
To display any active VPN connection, run:
To close the Nuremberg TCP VPN connection run:
openvpn3 session-manage --config DE-Nuremberg-CactusVPN-TCP.ovpn --disconnect
