How to connect to wireless AP with NM 0.7.1

[Scott Parker]

I'm creating a console application which needs to be able to identify 
and to connect to wireless access points.


So far I have been able to scan and parse the access point I wish to 
connect to but I'm having trouble understanding how to actually connect 
to it now. From reading the source for the applet I have been able to 
come up with this.


s_wireless = (NMSettingWireless *)nm_setting_wireless_new ();
ap_ssid = nm_access_point_get_ssid(ap);

g_object_set(s_wireless, NM_SETTING_WIRELESS_SSID, ap_ssid, NULL);
g_object_set(s_wireless, NM_SETTING_WIRELESS_MODE, "infrastructure", NULL);

connection = nm_connection_new();
nm_connection_add_setting(connection, NM_SETTING(s_wireless));

s_con = NM_SETTING_CONNECTION(nm_setting_connection_new());
g_object_set(s_con, NM_SETTING_CONNECTION_TYPE, 
nm_setting_get_name(NM_SETTING(s_wireless)), NULL);


nm_connection_add_setting(connection, NM_SETTING(s_con));
specific_object = nm_object_get_path (NM_OBJECT(ap));

g_assert(connection);
con_path = nm_connection_get_path(connection);
g_assert(con_path); /* FAILS HERE */

nm_client_activate_connection(app->priv->client, 
NM_DBUS_SERVICE_USER_SETTINGS,
  con_path, device, 
specific_object, activate_connection_cb, app);


After I filter and select the access point (unencrypted) that i want to 
connect to I'm unable to get the path of the NMConnection I have 
created. The nm-applet is not running.


Thanks

NM forgets CA certificate

[Matthew Saltzman]

I don't recall if I wrote before about this, but I don't think so.  I've
been thinking about it.

I have a PEAP connection that requires a separate CA cert from the usual
bundle.  The first time I connect after a reboot, the connection always
times out.  When the configuration dialog pops up, it shows "CA
certificate: (None)".  Opening the dialog allows me to select the cert
file and then the connection is fine (although the Wireless Security
config window shows no cert), even across movements to another network
and back, until the next boot or NM restart.

Also, it seems that I should be able to use the cert as I got it from
Entrust as a .cer or after conversion to a .der, but neither of those
works for me (although it does work for others).  I had to get someone
to send me a .der that we knew worked, and I use that.

Re: [PATCH] Adding OLPC Mesh device to libnm-glib library

Bother; found out that the olpc-mesh device Companion property should
really be an object path instead of a string, like the wifi device's
active-ap property is.  I'll need to fix up the NM side of this and then
you can respin this patch with the right bits to expose the companion
device as a real NMDeviceWifi object instead...

At least for PPP we can get traffic counts via ioctls.  I'd like to get
traffic counts for the other devices like ifconfig does, but last I knew
ifconfig got that by scraping /proc/net/dev which is just ugly.  We may
be able to get updated traffic counts from netlink somehow?

Re: Problem to add a broadband connection on NetworkManagerUserSettings

[Maxwell Chiareli Xandeco]

I'm using Ubuntu 9.10, with your code I don't get errors but a
connection is not added, nothing happens when I call AddConnection
method.

Follow my policy file:

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 ?
