Hi all,

 

After reading DBus API http://projects.gnome.org/NetworkManager/developers/spec-07.html#org.freedesktop.NetworkManager

I try to list all connection setting by below interface specification

 

org.freedesktop.NetworkManagerSettings

The NetworkManagerSettings interface is provided by the service which provides connections to NetworkManager.

Methods:

ListConnections ( ) → ao

List the connections stored by this Settings object.

Returns

 

connections - ao

    List of connections.

 

Signals:

NewConnection ( o: connection )

Emitted when a new connection has been configured.

Parameters

 

connection - o

    Object path of the new connection.

 

Interface has no properties.

 

 

Without success. DBus service say:

 

Traceback (most recent call last):

  File "./python_dbus_client", line 21, in <module>

    connections = manager.ListConnections()

  File "/var/lib/python-support/python2.6/dbus/proxies.py", line 140, in __call__

    **keywords)

  File "/var/lib/python-support/python2.6/dbus/connection.py", line 622, in call_blocking

    message, timeout)

dbus.exceptions.DBusException: org.freedesktop.DBus.Error.UnknownMethod: Method "ListConnections" with signature "" on interface "org.freedesktop.NetworkManager" doesn't exist

That's because ListConnections is a method of the "org.freedesktop.NetworkManagerSettings" interface ;)

Try executing your method as:

connections = manager.ListConnections(dbus_interface="org.freedesktop.NetworkManagerSettings")

Best regards,
