Although it is quite strange...i git cloned your cnetworkmanager and stuff like './cnetworkmanager -a' or './cnetworkmanger -d'  work just fine.

But the single piece of python you gave earlier doesn't.

-sh

Here is my output on your pyhton script:

---------------------------------------------
./nm-test.py 
Wifi enabled: org.freedesktop.DBus.Error.UnknownMethod: Method "Get" with signature "ss" on interface "org.freedesktop.DBus.Properties" doesn't exist

NetworkManager is not running
---------------------------------------------

So it definitely doesn't work for me.Oh and NM is running...your choice of printing "NM is not running" upon every exception is the fault.

Here the output of NetworkManager --no-daemon:

Although nothing related to dbus interface stuff.Were the past ended is exactly where i run the python script...but nothing related to it happens in NM's <info>.

The DBus error messages could be certainly improved, I think.

Here is code that works for me (extracted from
http://repo.or.cz/w/cnetworkmanager.git ).
