[maemo-developers] Aw: [maemo-developers] Scanning WLAN problem

[From: Mathias Uebelacker]

Hello Kalle,

what is the exact szenario? For what kind of job do you need this informations?

I do something like that with kismet. Kismet connect a lot of information and write these Infos on mmc. You have two possible ways to get these Information:

1. Transfer these files via bluetooth
2.  Use the tools from kismet.

What ever all jobs like these are critical. You should disable all processes you do not need. If you dont close these processes the files of the collected datas will need all your free resources. Spend some thoughts to the legal or ethical aspect.

These works by moeving too. You can receive GPS coordinates of the found networks.

In my opinion the N770 works as a "collector" to get Informations for penetration test or like a sensor monitor for IDS IPS.

But always watch your borders - legal and hardware limitations!!!

Here are some usefull links:

But in my opinion the devices N770 and N800 could be powerful weapons no matter for which side you work. It should be the legal side :-)

regards
Mathias

Betreff: [maemo-developers] Scanning WLAN problem
Hi all,

I'm developing an application to Nokia 770 which scans available network
infomation and then sends collected infomation to server.

I'm using modifed wireless tools (
http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html) wlist
source which works fine and
I can get all WLAN netwok information I need, but I can't send them to
server because in order to get the scanning to work the current
working network connection must be disconnected.

If I use script to connect to network automatically the problem still
exists:

#!/bin/sh
source /usr/bin/connectivity_preload
.sh
./wifiscan

If I have network setup I cant perform scanning iwlist prints'Interface
doesn't support scanning'. This is because function iw_get_range_info in
iwlib.c
returns !=1.

My questions are:
1. Is there a way to get scanning to work while the network connection is
on?
2. If not what is the best solution to implement requested functionality
(scan network -> send information to server)?
3. How does N800 work in this scenario?

Any help would be appreciated.
Thanks in advance.

- Kalle
