# Requirements

  1. Confirmed collection of secret keys in Step 1 of onboarding process.

# 2.1 Install the VPN software

Windows

We use the open-source application OpenVPN to ensure encrypted communication between your local computer and us.

Download and install OpenVPN using the latest stable Windows Installer (Avoid beta versions) (opens new window)

Click on the link above, scroll down to the file named OpenVPN-<version-number>-i601-amd64.msi (Windows 10 users), download the file and follow the on-screen installation instructions.

NTNU users: Windows users from NTNU can install OpenVPN community edition using NTNU Software Center even without administrative rights.

WARNING

You will need administrative rights on your local computer to successfully install OpenVPN.

Click on the link below if you do not hold administrative rights on your local computer, or don't know if you have such rights.

Installing OpenVPN without administrative rights

You can check if you have administrative rights on your local computer by running net localgroup "Administrators" in a command prompt (opens new window) and see if your username is listed.

Request assistance from your local IT personnel if you do not hold administrative rights on your local computer and request that they:

(1) assist you in the OpenVPN installation, or

(2) grant you administrative rights on your local computer so you can install OpenVPN yourself.

For simplicity, we have outlined the steps they need to perform, which you can attach to your request: https://docs.hdc.ntnu.no/do-science/guides/openvpn-admin-group/

# VPN connection failed

If you received the notification VPN Connection Failed after 60 seconds, please check the following

  • Verify that you have an active internet connection.
  • Verify that the Private Key Password is correct.

# Could not read Private Key error
