Step-by-step instructions[Bearbeiten | Quelltext bearbeiten]
Create network certificate[Bearbeiten | Quelltext bearbeiten]
To use OpenVPN, you must first install a personal network certificate.
If you use the WLAN "eduroam", the certificate is already installed on your computer.
Configuring VPN on Linux[Bearbeiten | Quelltext bearbeiten]
Download the configuration file, select the VPN you want to connect to and click on Download.
Normally "Uni-VPN (Standard)" should be the right choice, but if you have problems with the connection, try "Uni-VPN-TCP" again.
At least version OpenVPN 2.4 is required.
Connection via the network manager of Ubuntu[Bearbeiten | Quelltext bearbeiten]
There is also the possibility to set up the connection via the network manager of Ubuntu.
To use the network manager, the previously created network certificate must be unpacked:
$ 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 two new files are copied to a secure location in the user directory with the network certificate.
To do this, the necessary packages must first be installed via terminal:
# sudo apt-get install openvpn network-manager-openvpn network-manager-openvpn-gnome
With the help of the Network Managers (network connections) a new VPN connection can be create. To do this, click on "Add".
In the next window the connection type OpenVPN must be selected.
Afterwards the just unpacked certificates must be selected. The CA certificate field should be filled automatically.
If the CA certificate field is not filled in automatically, the configuration file "openvpn-upb-ng-lin.ovpn" should be renamed to "openvpn-upb-ng-lin.pem" and additionally placed in the folder with the certificates. Then you can select the file as a CA certificate.

After saving, the VPN connection can be activated via the upper system bar.
