dear nick,
Thank you very much for helping me to understand the structure of NM and
the relationship between NM and applet.
I have some more questions about NM and wish you can help me again.Today I met
a problem on DHClient.
(1) The log is like "localhost dhclient: Can't create
/usr/local/var/run/dhclient-wlan0.pid: Permission denied".
I downloaded dhclient-3.0.6 src code but still did not find how to change
"path_dhclient_db". Maybe it is not printed from dhclient.c.
I still have some questions about NM.
(2) Can I interpret the relationship between NM and applet like following
diagram?
|------------- src
--------------| |- libnm -|
NIC_Driver<->wpa_supplicant<->NetworkManager <-> NMManager <->
NMClient <-> Applet
(iwctrl) (dbus) [NM
database] (dbus sig) [NMA database]
(3) I could not find the place applet emits a signal "DeviceAdded", so how does
applet create a NMClient?
(4) I will be so glad to know the calling history about "the wireless device
has scanned a new network/ap".
I means how NM informs Applet to add a new network.
(5) Also I would like to know the calling history about "user select an ap to
associate".
I means how Applet informs NM to perform joining things.
(6) Last question :Connection is for a device or an ap?
Sorry to have bothered you so much.
sincerely,
Jeanne
