HAW Hamburg VPN under Linux

Since CISCOs AnyConnect VPN doesn't support Linux, we need to use an open source implementation. I suggest to use openconnect.

Under Arch Linux you might download it via. pacman -S openconnect. After you downloaded it, you might connect with sudo openconnect <address>;. The programm will ask you for your A-Label and your password. These are the same credentials you use for your helios and e-mail access on haw-mailer.haw-hamburg.de/owa.

Here is an example how it looks like:

sudo openconnect connect.haw-hamburg.de
[sudo] password for user: 
POST https://connect.haw-hamburg.de/
Attempting to connect to server 141.22.5.20:443
SSL negotiation with connect.haw-hamburg.de
Connected to HTTPS on connect.haw-hamburg.de
XML POST enabled
Please enter your username and password.
