Hi y'all,

i just downloaded and installed ipw2200 drivers and firmware, no
problems, even scanning works. But my network is protected by WPA-PSK,
so i need wpa_supplicant (or is there any other way?). I downloaded the
sources, created the config file like this:

CONFIG_DRIVER_IPW=y
CONFIG_DRIVER_WEXT=y
# CONFIG_DRIVER_BSD=y
# CONFIG_DRIVER_NDIS=y
CONFIG_WIRELESS_EXTENSION=y
CONFIG_IEEE8021X_EAPOL=y
CONFIG_EAP_MD5=y
CONFIG_EAP_MSCHAPV2=y
CONFIG_EAP_TLS=y
CONFIG_EAP_PEAP=y
CONFIG_EAP_TTLS=y
CONFIG_EAP_GTC=y
CONFIG_EAP_OTP=y
# CONFIG_EAP_SIM=y
# CONFIG_EAP_AKA=y
CONFIG_EAP_PSK=y
CONFIG_EAP_PAX=y
CONFIG_EAP_LEAP=y

and compiled it, then copied the binaries to /usr/local/bin. This is my
/etc/wpa_supplicant.conf:

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0

eapol_version=1
ap_scan=1
fast_reauth=1

### Associate with any open access point
### Scans/ESSID changes can be done with wpa_cli
network={
ssid="ssid"
scan_ssid=1
proto=WPA
key_mgmt=WPA-PSK
psk="topsecret"
}

But when i enter

wpa_supplicant -B -i eth1 -c /etc/wpa_supplicant.conf -D ipw -w -dd

it only prints "Daemonize.." and the command prompt appears again,
while nothing is changed in iwconfig. Am i doing anything wrong? Been
searching around forums, but haven't found anything else. Can someone
help me pls? TIA

This part is normal, given that you're running wpa_supplicant as a
daemon. Are you able to confirm that wpa_supplicant remains running?

> while nothing is changed in iwconfig.

By this, I take it to mean that you see no sign of successful
association with the access point, correct?

Can you run wpa_supplicant in foreground mode, perhaps with debugging
output, and see if the ouput tells you anything helpful? Can you check
also the access-point's logs for anything that might help?

UPDATE:

I also tried the wpa_supplicant package found at
http://www.slackware.com/~alien/slac...4.7-i486-1.tgz,
but the outcome was the same: nothing happened. That might suggest the
problem isn't in supplicant after all, but where else? I'm quite sure
the ipw firmware and driver work ok. Any help appreciated.

Perhaps you haven't configured your pre-shared keys in wpa_supplicant?

("PSK" in "WPA/PSK" stands for "Pre-Shared Keys". That means both
wireless stations, access-point and client, have a set of common
encryption keys prior to associating ...)

> P.S. i know my ssid is published here... i don't care

Two points on that:

- Contrary to what a lot of wireless equipment manufacturers will have
you believe, your SSID is not any kind of secret. Any wireless
equipment within reception range of yours can pick up the SSID
(whether or not your access point broadcasts it in its beacons)
when the wireless link is being used. It's sent, in the clear,
as part of the overhead of every packet sent over the wireless link.

- If you're still concerned, (and the rest of what I'm going to say is
something that you very likely already know), the SSID is trivial
to change, unless you have a large number of client systems that
you don't manage yourself.

You may need to reconfigure your kernel, eliminating the default ieee80211
and ipw2200 modules from the kernel configuration. When I set this up, I
was using a Pentium M based laptop- so I had already configured the kernel
for that hardware, and that was one more tweak on top of it. You may not
need to do this, but I did. The kernel was using an out-of-date centrino
driver which needed to be replaced. I am not sure which version of the
driver is in the current kernel source.

Here was a kernel configuration that I used for 2.6.14.3
http://www.xmission.com/~ddmayne/sla...6.14.3m-acpi-7

Perhaps you could recompile the kernel, upgrading to 2.6.16.16 at the
same time. You could do "make old_config" for 2.6.16.9 (using the official
slackware config), then adjust for your hardware, and the wireless tweaks in my
configuration.

The last time I posted these instructions, these were "current" sources.
They may have been updated since then.

The driver:
http://prdownloads.sourceforge.net/i...2.tgz?download

The firmware:
http://ipw2200.sourceforge.net/firmware.php?fid=6

The ieee80211:
http://prdownloads.sourceforge.net/i...2.tgz?download

The wpa_supplicant:
http://hostap.epitest.fi/releases/wp...t-0.4.8.tar.gz

The libdnet:
http://prdownloads.sourceforge.net/l...ar.gz?download

The libpcap:
This was already on my system.

I also have a 2.6.15.4 kernel for Pentium M which is already compiled,
with modules, etc. I'll hold off posting that, unless you want it.

I use wpa_supplicant at home with wpa-psk, madwifi, and ndiswrapper,
config looks just a little bit simpler:

# cat /etc/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
eapol_version=1
ap_scan=1
fast_reauth=1

network={
ssid="xxxxx"
psk="xxxxxxxxxxx"
priority=5
}

IIRC the priority bit isn't necessary either. Also, I've upgraded my
wireless-tools package to version 28.pre13. There's a package of version
28 at

http://www.slackware.com/~alien/slac...ools/pkg/10.2/

Note that I'm only going on differences between config-files, not on
good knowledge of wpa_supplicant. But it can't hurt to try :-)

That's definitely not the case.

I know an awful lot about wpa and wpa-psk, no need to tell me, thx.

Thanks, i know all this too. The sole reason why i put the "P.S" was
that someone in this group (or was it you?) mentioned it's unwise to
publish compiled kernels, coz it might leak some personal info. Then i
got a feeling most of you are security freaks. Kinda sarcasm from my
part, sorry

Whoa, you've got a kernel to offer?? Of course i'd accept it!

Hope y'all won't ostracize me from now on, but not being able to use
wifi is for me by far the worst news in Linux. Far worse than hosed
graphics. I need it functioning ASAP to surf the Net comfortably from
Slack, bowse howtos and forums (and post requests

Back to the kernel: yes please, post it. TIA

Cut and paste from a previous posting:
These are the instructions. These are the approximate steps to follow.
Use at your own risk. Linux kernel is GPL. GPL license applies also:
http://www.xmission.com/~ddmayne2/kernel/COPYING

Compiled with gcc version 3.4.5
md5sums:
http://www.xmission.com/~ddmayne2/ke...6.15.4/md5sums

kernel 2.6.15.4:
http://www.xmission.com/~ddmayne2/ke...-acpi-2-dm.tgz

kernel modules:
http://www.xmission.com/~ddmayne2/ke...-acpi-2-dm.tgz

Firmware:
Read and accept license before using:
/lib/firmware/LICENSE
http://www.xmission.com/~ddmayne2/ke...rmware-2.4.tgz

Includes:
alsa-driver 1.0.10 (with minor patch)
ieee80211-1.1.6
ipw2200-1.0.7
Intel firmware 2.4

So, to install this kernel:
0. Download and verify (md5sums) the packages linked above.
1. installpkg kernel-2.6.15.4m-acpi-2-dm.tgz
2. installpkg kernel-modules-2.6.15.4m-acpi-2-dm.tgz
2.a. Fix link to /etc/rc.d/rc.modules
(maybe not necessary if you are already running a 2.6 kernel)

# cd /etc/rc.d
# mv rc.modules rc.modules.save
# ln -s rc.modules-2.6.15.4m-acpi-2 rc.modules

3. installpkg ipw2200-firmware-2.4.tgz
4. Fix boot loader to reflect new kernel per usual drill.
4.a. Look in /boot for the vmlinuz file to load.
5. Reboot with new kernel.
6. Run alsaconf to configure sound.
7. Test if wireless is working.*
8. Test if processor scaling and acpi are working, etc. **

* Beyond the scope of this post.
** Suspend features may or may not work. They are not working
correctly (yet) on the Dell D610. YMMV.

Also, remember, these files compiled by me. Use at your own risk.
