 ====== OpenConnect (Linux) ======
-On Linux systems either the Cisco AnyConnect-Client or the free vpnc can be used to connect to the VPN.
+On Linux systems, both the Cisco AnyConnect-Client and its open implementation **OpenConnect** can be used to connect to the VPN.
-Since vpnc can be integrated in the NetworkManager and can automatically connect to the VPN if it is connected to a certain ssid e.g. GuestOnCampus it is more convenient to use vpnc if NetworkManager is used anyway.
+We encourage you to use OpenConnect.
