Setting up the Assessment VPN

Installation and configuration of OpenVPN

Our assessment team may utilise OpenVPN to provide access to your machines and we have developed the process below for the installation of the required software.

Download and Install OpenVPN

Open a terminal window on your Linux Distro

For ease, elevate your session to SUDO with the sudo -i command or prefix all other commands shown here with sudo

sudo -i

Either enter your password (if you are a member of the SUDO group) or use the su command to access an elevated terminal session with another SUDO user

su root

You should then see your access change, for example, here, we can see we are now a root user

As always, we recommend ensuring your system is up-to-date before installing any software applications, so consider running a check before you start with the relevant update commands for your distro, for example apt-get update && apt-get install -y

apt-get update && apt-get install -y

You now need to install the OpenVPN software using the process specific for your Linux Distro, for example apt-get install openvpn

apt-get install openvpn

Select "Y" to confirm the installation which will then complete

You will then need to download the configuration file from the Assessment Platform Website using a browser, you can log in here

NOTE: LOGIN NAME/PASSWORD is case sensative

Once you have logged in, you need to download the Yourself (autologin profile) file

The file will be saved to your Downloads folder

From a non SUDO terminal, access the Downloads folder - note capital "D"
(If you are in SUDO session, you will not see your own users Downloads folder)

cd Downloads

Check you are in the correct directory with the pwd command


And list the files in the directory to ensure the client.ovpn file is there with the ls command


Then copy the client.ovpn file into the /etc/openvpn folder but renaming it to cts.conf

sudo cp client.ovpn /etc/openvpn/cts.conf

Check the file has copied correctly into the /etc/openvpn folder with the ls command

ls /etc/openvpn

We then need to edit the openvpn configuration file /etc/default/openvpn

sudo nano /etc/default/openvpn

Locate #AUTOSTART="all" and remove the #

When you have finished editing, press CTRL + X, confirm "Y" to save the file and press "ENTER" when asked about the filename.

From the non-sudo command prompt you need to move into the /etc/openvpn folder

cd /etc/openvpn

Confirm you are in the correct location with the pwd command


You can now test the VPN connection by executing OpenVPN with the cts.conf file as the parameter

sudo openvpn cts.conf

OpenVPN will then execute and will consume the terminal (not providing a prompt return and staying resident)

You can press CTRL + C to terminate the OpenVPN connection

You can then set the OpenVPN connection to start automatically (saving a manual start) by additing this as a service.

First add openvpn with the cts.conf as a service

sudo systemctl enable openvpn@cts.service

Then reload the daemon

sudo systemctl daemon-reload

Then start the OpenVPN service

sudo service openvpn@cts start

You are now connected to our assessment platform, please reach out to one of our assessors who will be able to confirm that you have a live connection.
