Ok, I'm using NetworkManager and found
http://people.redhat.com/dcbw/NetworkManager/NetworkManager%20DBUS%
20API.txt

I tried 

dbus-send --system --dest=org.freedesktop.NetworkManager
--print-reply /org/freedesktop/NetworkManager/Devices/eth1
org.freedesktop.NetworkManager.getActiveNetwork

but get the follwing error:

Error org.freedesktop.DBus.Error.UnknownMethod: Method
"getActiveNetwork" with signature "" on interface
"org.freedesktop.NetworkManager" doesn't exist

Thanks for your help!
