Hello folks,

I'm new to NetworkManager, getting familiar with D-bus interface etc.
I'd like to create a high level Python interface for nm, but I have trouble
with insufficient documentation resources (or my Google skills).

Is there any tutorial or D-bus code example for e.g. creating a bond device
with defined IP? I've found plenty of 'list devices' but nothing like this.

What's wrong with this project https://github.com/seveas/python-networkmanager ?


See also,
http://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/examples/python/dbus which are examples for 
using Python to access the D-Bus interface directly.


then there is also
http://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/examples/python/gi
which uses libnm via gobject introspection. If you want something quick,
this might be better. If you want to implement the best possible python
NM library, you might don't want to use it.

Note that libnm will always be installed together with NetworkManager,
so the additional dependency is not that cumbersome.
But libnm was only introduced with nm-1-0, so if you want to support
older NM (too), you must use the now deprecated libnm-utils library.
http://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/examples/python/gi?h=nm-0-9-10
The deprecated library libnm-utils also works with NM 1.0 and newer, but
it is... deprecated.


The D-Bus API for NM is quite stable, so if you are using D-Bus
directly, you should easily be able to support various version of
NetworkManager.



I didn't look at python-networkmanager, but that might be worth using
(and improving) instead of adding yet another wrapper.
