On 30/03/2023, the certificates for the VPN service were updated. You can use VPN only if you have installed the current configuration file. You do not need to install a new user certificate.
VPN (Virtual Private Network) is needed if you want to use your computer from outside the university to access services that are only accessible within the university network. VPN guarantees secure access to the university network through other networks (dial-up via other providers, external company or university networks).
This guide is based on Ubuntu 22.04.2 LTS. Other distributions may work similarly. We cannot provide a guide for every distribution.
What needs to be done?[Bearbeiten | Quelltext bearbeiten]

Check VPN[Bearbeiten | Quelltext bearbeiten]
You can check your VPN connection by visiting:
Advanced[Bearbeiten | Quelltext bearbeiten]
- OpenVPN 2.4 or newer is mandatory.
- You can setup VPN via the network manager.
- The certificates need to be unpacked first:
$ openssl pkcs12 -in Network_Certificate.p12 -out Network_Certificate_OPVPN.crt.pem -clcerts -nokeys$ openssl pkcs12 -in Network_Certificate.p12 -out Network_Certificate_OPVPN.key.pem -nocerts -nodes
The network certificate and the config file need to be stored in a secure area of the user directory.
- Under OpenSSL 3.0.2 maybe an additional parameter is necessary:
-legacy - It my be necessary (e.g. Arch) to install the "openssl-1.1" package and run the prompts above with "openssl-1.1" instead of "openssl".
You need to install the required packages via terminal:
# sudo apt-get install openvpn network-manager-openvpn network-manager-openvpn-gnome
