openconnect on Ubuntu

To be able to work freely you have to build up a VPN connection to this university.
Proceed as follows:

unlock universe sources:
- open System Settings
- System
- Software & Updates
- Ubuntu Software
- select Community-maintained free and open-source software (universe)
- Close
- Finaly answer "Reload" on the question if you want to update the cache
install the following pakages:
- Ubuntu/Debian:
  - network-manager-openconnect
  - network-manager-openconnect-gnome
  for example in the terminal with sudo apt-get install network-manager-openconnect network-manager-openconnect-gnome
- openSUSE 13.2:
  - NetworkManager-openconnect-0.9.10.0-2.1.4.x86_64
  - openconnect-6.00-3.1.3.x86_64
- Arch Linux
  - networkmanager-openconnect
- open the Network-Manager
  - Add and choose a Connection Type ⇒ Multiprotocol-VPN-Client (openconnect), not ~~Cisco-Compatible VPN-Client (vpnc)~~
  - Connection name: TUHH-VPN (arbitrary)
  - General:
    - Gateway: any1.rz.tuhh.de
    - CA-Certificate: /etc/ssl/certs/T-TeleSec_GlobalRoot_Class_2.pem ( ⇒ Download )
  - Connect to TUHH-VPN
  - enter RZ username and password
- for the console: sudo openconnect any1.rz.tuhh.de
There is an alternative or secondary gateway: vpn.rz.tu-harburg.de
You can repeat the steps above to create an option against the failure of the main server.

Nur das TUHH Netzwerk durch dass VPN routen

Sie überschreiben hiermit lokal auf eigene Verantwortung die Routen / Strecken, sodass Sie beispielsweise für Verlage nicht aus der TUHH kommen und in offenen WLAN Netzwerken keine vollständige Verschlüsselung genießen.

Bearbeiten Sie die TUHH VPN Einstellungen und öffnen Sie den Reiter IPv4. Die Option Diese Verbindung nur für Ressourcen in deren Netzwerk verwenden verhindert das Setzen der Routing Regel mit der alle Pakete durch das VPN getunnelt werden. Die eigene Route / Strecke definiert dafür manuell das TUHH Netzwerk:

Adresse: 134.28.0.0
Netzmaske: 255.255.0.0
Gateway: 0.0.0.0
Metrik: 5

Die Routen sollten bei einer neuen Verbindung wie folgt aussehen:

$ route -n
Kernel-IP-Routentabelle
Ziel            Router          Genmask         Flags Metric Ref    Use Iface
0.0.0.0         0.0.0.0         0.0.0.0         U     50     0        0 vpn0
134.28.0.0      0.0.0.0         255.255.0.0     U     5      0        0 vpn0
