Re: [Airo-linux-general] Aironet 340 and Redhat 7.3 woes

[Kevin <lei...@ne...>]

Hi,

I just went through a lot of this on Mandrake 8.2 with 2.4.18 and later 
kernels, I have the 350 card, I'll tell you what I know.  

My experience was, when compiling w/o kernel pcmcia, and using pcmcia-cs 
instead (which is supposed to work per readme)  the airo-linux driver 
appears not to compile correctly on the current stable kernel 2.4.18,
and the project maintainer hasn't communicated if he intends to resolve 
this.

I tried on 3 different systems and 2 distributions, serveral versions of 
pcmcia-cs, same problems throughout.

Anyway, it appears that promisc mode is only available once the wifi 
interface was introduced.

You'll notice on the CVS that the wifi interface wasn't introduced in 
airo.c until CVS rev 1.35

http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/airo-linux/airo-linux/kernel/airo.c

When I try to compile CVS rev 1.35-1.37 it will compile, but depmod 
complains of unresloved symbols, and promisc mode doesn't work if I 
actually use the driver.

When I try to compile airo.c CVS rev 1.38-1.41 I get errors complaining 
about the EXPORT_SYMBOL( ) macros introduced in 1.38+.

The good news is I discovered a gentleman who's made a variation of the 
airo-linux driver for his Airtraf software.  Promisc mode DOES work for 
me using that driver, though it does
complain of unresolved symbols from depmod, the driver works fine for me.

http://prdownloads.sourceforge.net/airtraf/airo-linux-mod-airtraf.tar.gz

I've read in some places that one has to listen on wifi0 once the card 
is in promisc mode.  I don't know if that's true with other variations 
of the driver but for me using airtraf I have listen on eth1 (eth0 being
my land line) , wifi0 doesn't seem to work.

Post back if you discover anything more on this if you would, this list 
isn't real active it's hard to dig up info on these. I think they're 
great cards, I hope the support base grows.  
I'm hoping we see a way to put these in AP mode at some point as well.

A couple links that may be useful though some info is out of date
http://www.goonda.org/wireless/aironet/

hope that helps.
