The purpose is to allow (some) access to servers, e.g. MATLAB license server, using a VPN (Virtual Private Network).

Install (Ubuntu/kubuntu)

Install the following packages: 

sudo apt-get install openconnect vpnc

Open connection

UPDATE: 2023-11-09, Use extra flag --useragent=AnyConnect

UPDATE: 2021-12-06, New VPN server with address https://vpn.dtu.dk, use extra flag --os=win

Run the following command: 

sudo openconnect --os=win --useragent=AnyConnect --script /etc/vpnc/vpnc-script https://vpn.dtu.dk/

or 

sudo openconnect --os=win --useragent=AnyConnect --script /etc/vpnc/vpnc-script https://extra-vpn.ait.dtu.dk/

(supply password for SUDO, and your logon credentials to campusnet when prompted)

NOTE: On newer versions of Ubuntu Linux the vpnc scripts are in the folder: /usr/share/vpnc-scripts/vpnc-script

Now you have a new network connection, check with ifconfig: 

ifconfig

If you installed MATLAB as described in http://downloads.cc.dtu.dk/# then you should now be able to run MATLAB using your DTU license.
