Re: WPA (was: OpenZaurus Wiki (http://wiki.openzaurus.org/) down?)

Hi all,
I'll wait for the openzaurus wiki to be available again; but for the
impatient; that's what I'll post there:

The following I created out of various source (listservers, howtos ...
nothing in here is

my invention) - unfortunately I did not note the origins in my notes; so
I can not pay

credits to those who would deserve it.
----
= configure hostap driver =
For Prism based cards we'll have to use the hostap drivers to be able to
use WPA; on my

collie by default the orinoco drivers were installed. The file you need
to edit to switch

drivers is /etc/pcmcia/hermes.conf. I added these lines @ top of the file:

***
device "hostap_cs"
 class "hermes"
 module "hostap", "hostap_cs"
***

Then find the definition for your card (further down in that file) and
change the

"orinoco_cs" reference to "hostap_cs". The definition for my card nows
looks like this:

***
card "Orinoco or Intersil Prism 2 Wireless"
  manfid 0x0156,0x0002
  bind "hostap_cs"
***

If you're not sure which entry is for your card, use 'cardctl ident' and
search in

/etc/pcmcia/hermes.conf for the "product info" it reports.

After editing /etc/pcmcia/hermes.conf, eject your card and restart the
PCMCIA services:
#> cardctl eject 0
# remove the card now ...
#> /etc/rc.d/init.d/pcmcia restart
# insert the card again

You can test if it has worked by running lsmod:
#> lsmod
Module     Size Used by Tainted: P
hostap_cs 45896 1
hostap    85568 0 [hostap_cs]
...
= install wpa_supplicant =
Use ipkg to install the wpa_supplicant packages; then add the following
section to

/etc/wpa_supplicant.conf:
***
network={
        ssid="the_networks_ssid"
        psk="the_secret_password"
        priority=5
}
***

= update firmware =

To be able to use WPA the card's firmware must be >= 1.7.4.
We can update the firmware (which was necessary in my case) with the
hostap-utils; for

this you'll have to install the following packages: prism3-firmware,
hostap-utils

/etc/pcmcia should now contain an updated RAM image for prism cards
(rf010804.hex).

= configure the interface =
Next you'll have to modify "/etc/network/interfaces" wlan0 section in
the following way:

***
# Wireless interfaces
iface wlan0 inet dhcp
        wireless_essid any
        wireless_mode Auto
        pre-up iwpriv wlan0 reset 1
        pre-up prism2_srec -r wlan0 /etc/pcmcia/rf010804.hex
        pre-up wpa_supplicant -B -w -i wlan0 -c /etc/wpa_supplicant.conf
        post-down killall -q wpa_supplicant
***

=> now WPA encription should work :-)

Tested with OZ 3.5.4 ib SL-5500G

hope this is helpful,
with kind regards,
