wireless howto[s] indepth ???
Michael D. Schleif
We have been tasked to analyze several expansive wireless networks for
functional, performance and security issues. So, we are investigating
how far we can go with debian-based laptops?
Yes, I have done several apt-cache search's, and found several
applications that may serve us well.
What we have not found is any website or howto that compares/contrasts
any of these apps, or goes into detail as to what to do and what not to
do.
What do you think?

Our capacity for understanding is inversely proportional to how much
we think we know. The more I know, the more I know I don't know . . .

Here's a good example of our confusion:

Should airsnort work with this configuration? I keep getting this
message:
`Could not set monitor mode'
Google is decidedly silent about this error ;<
Or, kismet, another example, does not appear to like the orinoco gold
card:
# sudo kismet_monitor
Using //etc/kismet/kismet.conf sources...

We have seen reference to some `snax' patch; but, I have not found
anything debian about it.
Elsewise, there are the linux-wlan-ng-modules-*, all of which apparently
require kernels 2.4.20 and above; which, of course, begs the question:
is full wireless support a function of the kernel?
Moreover, are stock debian kernels adequate to all wireless tasks? Or,
need we compile our own?
We are confused and no brighter for our research . . .

Secondly, the orinoco_cs driver is only recently becoming half decent
(although still not there, IMHO). The recent kernels (2.4.21 and .22-pre
releases) all use the latest orinoco 0.13 driver, which is likely not
available in 2.4.18-bf2.4. If you want to stay with the orinoco driver,
try a more recent kernel release, or try compiling your own orinoco
drivers from
http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Orinoco.html.
After many hassles with the orinoco driver (it still fails under heavy
load) I switched to the linux-wlan-ng drivers, which haven't failed me
yet. The installation is very straightforward and simple (if you have
already got kernel sources installed - for pcmcia-cs). The driver for
11Mbs cards is at:
ftp.linux-wlan.org/pub/linux-wlan-ng
Lastly, although I have never seen your airsnort error message, I have
successfully used airsnort with the linux-wlan-ng drivers.
