VPN installation on Linux

According to a recent statement of the computing centre, VPN clients but Cisco Anyconnect are no longer able to establish VPN connections with university hamburg

The Computing Centre has instructions (in German), how to install the Cisco Anyconnect Client under Linux (Ubuntu). However, we recommend rather to use OpenConnect, which in most Linux distributions can be installed directly from the package sources.

For Debian / Ubuntu and derivatives, please enter the following in the command-line:

sudo apt-get install --install-recommends network-manager-openconnect-gnome
sudo service network-manager restart

After installation click on the network-symbol, choose in the menu “VPN-Connctions” → “Configure VPN”.
In the new window, click the button “Add”, and you will see a new window “Choose Connection Type”.

Choose in the dropdown-list to the entry “Cisco AnyConnect compatible VPN-Connection (openconnect)” and click the button “Create”.

In the VPN-Configuration window choose as connection name for example “UHH-VPN”. Enter the following in the Tab “VPN”:

Gateway: vpn.rrz.uni-hamburg.de
CA-Certificate: /etc/ssl/certs/Deutsche_Telekom_Root_CA_2.pem

Leave the standard-settings in the remaining fields and click the button “Save”.

To login to the VPN please provide your UHH-Account-Name: e.g. fmnv165, followed by your RRZ-Password (same password as for your email-account).
