-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.
