That's a bug then; I fixed one specific bug with nm-connection-editor
caused by an older version of the polkit-gnome packages.  We'd need more
logs, pointers to logs, stacktraces, or Launchpad links to figure that
out.  It's probably a bug, and we need to figure out more details before
we can fix it.

That's somewhat unfortunate, because for a variety of security reasons
programs themselves are not allowed to change network information via
the D-Bus interface.  You can however use GConf (see gconftool-2
--import) to do this if you really need to.

Re: Problem to add a broadband connection on NetworkManagerUserSettings

2010-01-21 Thread Maxwell Chiareli Xandeco 

Hi guys,

I tried with SystemSettings before use UserSettings and really works,
but when you create a connection with "SystemSettings", it's marked as
"Available for all users", and when you use this kind of connection, you
just can use once, the second time crashes the system, there is a lot of
issues opened on launchpad about it, because of that I need to use
UserSettings.

Happens for broadband and DSL connections, may be to wireless too, it's
not just about connections created with my own code, I tried with
nm-applet, if you check available for all uses, don't works.

If someone knows some workaround to get SystemSettings working, I can
use it.

Thanks guys for your help, and sorry again about the "Legal message",
it's not my faul, but I'll start use other email.

Maxwell

Right; mainly because it's user settings, allowing any program to add
connections isn't necessarily secure.  However, any program can write
GConf so it's mostly a misnomer.  In the future we do want to allow
this, subject to various security considerations or at least
notifications.  For now, only system settings allows connection addition
because it actually validates caller's via PolicyKit.

Actually, there is an error causing critical error (g_error_new (0, ...))

g_error_new (0, ...
(nm-applet:27425): GLib-CRITICAL **: g_error_new: assertion `domain != 0' 
failed
(nm-applet:27425): GLib-CRITICAL **: g_error_free: assertion `error != NULL'

The attached patch fixes that. D-Bus then returns an error message on 
AddConnection.

I've investigated it a bit and found out that AddConnection is not supported 
via D-Bus due to security reasons.
(src/gconf-helpers/nma-gconf-settings.c:add_connection() function)

If you use SystemSettings service instead of UserSettings, the connection 
adding will work (just keyfile plugin).

I'm using Ubuntu 9.10, with your code I don't get errors but a

The error says that you don't have permissions.
It's caused by not specifying interface which the method AddConnection should 
be called on.

so do:
sys_bus = dbus.SystemBus()
proxy = sys_bus.get_object("org.freedesktop.NetworkManagerUserSettings", 
"/org/freedesktop/NetworkManagerSettings")
iface = dbus.Interface(proxy, "org.freedesktop.NetworkManagerSettings")

iface.AddConnection(settings)

Btw, what distribution do you use and what policies do you have in 
/etc/dbus-1/system.d/nm-applet.conf ?

Problem to add a broadband connection on NetworkManagerUserSettings

2010-01-12 Thread Maxwell Chiareli Xandeco 
Hi all,

I trying to add a new broadband connection using dbus python API:

settings = dbus.Dictionary({dbus.String(u'connection'):
dbus.Dictionary({dbus.String(u'timestamp'): dbus.UInt64(1263301788L,
variant_level=1), dbus.String(u'autoconnect'): dbus.Boolean(False,

dbus.String(u'8a0e02d9-9b1a-463b-a089-7a68140bf4c3', variant_level=1),
dbus.String(u'id'): dbus.String(u'Vivo Default', variant_level=1)},
signature=dbus.Signature('sv')), dbus.String(u'ppp'):
dbus.Dictionary({}, signature=dbus.Signature('sv')),
dbus.String(u'gsm'): dbus.Dictionary({dbus.String(u'username'):
dbus.String(u'vivo', variant_level=1), dbus.String(u'band'):
dbus.Int32(0, variant_level=1), dbus.String(u'apn'):
dbus.String(u'zap.vivo.com.br', variant_level=1),

sys_bus = dbus.SystemBus()
proxy = sys_bus.get_object("org.freedesktop.NetworkManagerUserSettings",

proxy.AddConnection(settings)

When I run this code i get a access denied error:

dbus.exceptions.DBusException: org.freedesktop.DBus.Error.AccessDenied:
Rejected send message, 2 matched rules; type="method_call",

Does someone have any idea?
