Thank Pablo for quickly reply,
I think I am misunderstanding something. I have rewritten my script as your
advice but I still error. Here is my short script:
#!/usr/bin/env python
import dbus
bus = dbus.SystemBus()
proxy = bus.get_object("org.freedesktop.NetworkManager",
"/org/freedesktop/NetworkManager")
proxy_prop = dbus.Interface(proxy, "org.freedesktop.DBus.Properties")
manager = dbus.Interface(proxy, "org.freedesktop.NetworkManager")
settings = dbus.Interface(proxy, "org.freedesktop.NetworkManagerSettings")
#active connection
connections = proxy_prop.Get("org.freedesktop.NetworkManager",
"ActiveConnections")
print "%d" % proxy_prop.Get("org.freedesktop.NetworkManager",
"WirelessHardwareEnabled")
print "%d" % proxy_prop.Get("org.freedesktop.NetworkManager",
"WirelessEnabled")
print "%d" % proxy_prop.Get("org.freedesktop.NetworkManager", "State")
for con in connections:
print "xxxx %s" % con
con_obj = bus.get_object("org.freedesktop.NetworkManager", con)
print "list connection "
connections =
manager.ListConnections(dbus_interface="org.freedesktop.NetworkManagerSettin
gs")
for con in connections:
print "%s" % con
It till say:

Please help.

Hi all,
After reading DBus API
http://projects.gnome.org/NetworkManager/developers/spec-07.html#org.freedes
ktop.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.NetworkManagerSettin
gs")
Best regards,
