We have rolled out a first, simple VPN again. You currently have access to various services via this, including ZFS1, Exchange, ticket system and various others.

Note: Please understand that this is a very simple VPN and that it is still a long way from providing "familiar" access as before. We will continue to work on this in the near future.

Prerequisites

  • Access to the two-factor authentication system (Note: The 2FA system is only accessible within the university for security reasons)
  • eduVPN client

Step 1

Download the eduVPN client for your operating system at https://www.eduvpn.org/client-apps/.

Step 2

Auswahl der TU Bergakademie Freiberg

Select TU Bergakademie Freiberg among the institutions

  • Access to the institute: Access to the campus data network (Attention: "Institute" here means TUBAF as a whole and does not describe an individual institute. We therefore recommend this selection for employees and students)
  • Secure Internet: Encrypted (secure) connection, without access to the campus data network

Step 3

Login mittels Shibboleth

A browser window now opens with the Shibboleth login screen with MFA.

TOTP Token Verifizierung

After you have entered your central user data, you will be asked for the second factor. Enter the second factor accordingly.

Genehmigung des VPN Clienten durchführen

Afterwards you can approve the process

TCP Connection zur Fehlerbehandlung nutzen

You are now connected to the VPN.

Reset eduVPN client

SURF-Verzeichnis löschen

There is no option to end a session in the VPN client. However, if this should become necessary for any reason, you must manually remove the existing configuration data on your end device. You can then log in again if required.

Step 1: Exit the eduVPN client

Please exit the eduVPN client first.

Right-click on the connection icon in the taskbar and select "Exit".

Step 2: Delete login data

Windows users

Start Windows Explorer (e.g. Win+E). Enter %LOCALAPPDATA% in the address bar.

You will now be taken to the C:\Users\Username\AppData\Local\ directory. This directory contains all environment variables. Search for the SURF directory. This was created by the eduVPN client and contains the old login data.

Now delete the SURF directory completely.

When you restart the eduVPN client, you can enter the new configuration data.

Linux users

You can delete the configuration data with the following command:

rm -fr .config/eduvpn

When you restart the eduVPN client afterwards, you can enter the new configuration data.

Troubleshooting

TCP Connection zur Fehlerbehandlung nutzen

If no data transfer is established despite an active connection, the WireGuard tunnel could not be set up.

In this case, please click on Settings at the top right and tick "Prefer TCP connection" or "Force TCP".

Note: This step is not necessary for Linux users as the client already supports an automatic fallback to TCP/OpenVPN.
