Re: [Gumstix-users] how to get automatic wireless status update

[said l. <sai...@gm...>]

Hi,

Your lucky guy, I completed it yesterday.

You need to write a script in */etc/init.d/* folder. You have the choice of
your script's name.
Then you run the command line *update.rc-d scriptName defaults* . It will
generate two files, which names begin by a 'K' or a 'S'. The K named files
are used when the system is shutting down or rebooting. The 'S' ones are for
starting.

Now let's see how to write this kind of script properly:

You can also define variables in your script but you have to report them as
well in a file with the same name as the script name (here *scriptName*) and
located in the folder : */etc/default/* .

Now you just have to read some files in your */etc/init.d/* and */etc/default/
*directories to know how to custom your scripts.

For managing your Wifi device :
if you use this command to start the wifi manager:

*wpa_supplicant* *-D **deviceType** -i **interfaceName** -c
/etc/wpa_supplicant/wpa_supplicant.conf -Bw *

*iwconfig* gives you the *deviceType*, (i think it's marvell) and also *
interfaceName*.

Most import you need to define the file *
/etc/wpa_supplicant/wpa_supplicant.conf.
*
This web site will help you in writing your *wpa_supplicant.conf:
*http://linux.die.net/man/5/wpa_supplicant.conf*

*
Hoping, it will interest you.
Nice day ;-) !!!
