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

Run the following command:

sudo openconnect --script /etc/vpnc/vpnc-script https://vpn.ait.dtu.dk/

eller

sudo openconnect --script /etc/vpnc/vpnc-script https://extra-vpn.ait.dtu.dk/

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

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

ifconfig
eth1     Link encap:Ethernet  HWaddr 00:1c:c0:81:cc:dd  
         ...
lo       Link encap:Local Loopback  
         inet addr:127.0.0.1  Mask:255.0.0.0
         ...

         inet addr:10.13.28.17  P-t-P:10.13.28.17  Mask:255.255.255.255

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.
