Newbie question

[David Lambert <dave lambsys com>]

I am a newbie to NetworkManager/dbus and in order to learn the interface 
am attempting to run the python script:

http://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/examples/python/nm-state.py

I get the error:

dlambert@development:~/Desktop$ python nm-state.py
Device eth0 is activated
Traceback (most recent call last):
  File "nm-state.py", line 58, in <module>
    con_details = con_iface.GetSettings()
  File "/usr/lib/pymodules/python2.6/dbus/proxies.py", line 68, in __call__
    return self._proxy_method(*args, **keywords)
  File "/usr/lib/pymodules/python2.6/dbus/proxies.py", line 140, in

    **keywords)
  File "/usr/lib/pymodules/python2.6/dbus/connection.py", line 620, in

    message, timeout)
dbus.exceptions.DBusException: org.freedesktop.DBus.Error.UnknownMethod: 
Method "GetSettings" with signature "" on interface 
"org.freedesktop.NetworkManager.Settings.Connection" doesn't exist


Any pointers as to where I can get details of the Python API or a 
tutorial would be appreciated.


Regards,

Dave.
