View source for Access DTU campus network using VPN from Linux

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==

<i>UPDATE: 2023-11-09, Use extra flag</i> <tt>--useragent=AnyConnect</tt>

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

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)

<i><b>NOTE:</b> On newer versions of Ubuntu Linux the vpnc scripts are in the folder:</i> <tt>/usr/share/vpnc-scripts/vpnc-script</tt>

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.
