Scanning for WiFi activity.

[gwl]

Hi,

I'm using my WL500G in client mode to connect to a remote AP.
In order to scan for avaliable wireless AP's, I run this:
> wl scan; wl scanresults;
which works quite well.

However, I would like to go one step further and check for activity in the current channel. (not the data transfer! just the MAC of the users...)
i.e.: Who else is using the same channel?

is it possible?

thanks,
:rolleyes:

Yes, use kismet.

Hi,

I've followed the instructions on the forum to get kismet running on the WL500.
Then I compiled the client part for cygwin, following this page: http://www.renderlab.net/projects/wardrive/wrt54g/kismetonwindows.html

It's working... :) but, when I run kismet on the router, I get:


[admin@g5 kismet]$ /tmp/kismet/bin/kismet_drone

if I run:


[admin@g5 kismet]$ wl monitor 1


and then:

If I try to connect from the laptop, with kismet client (cygwin), I do manage to connect (and kismet works!!), but I always get the "prism0: Invalid argument" from the telnet session.

Kismet drone works, but always reports: "prism0: Invalid argument"
What's wrong?

Is it possible to run the kismet client in the router? (and access it via telnet?)
