Problems capturing packets

03-09-2002

Hi,

I also have a problem with capturing packets.
My setup is very small - only one AP and one Laptop on which the following software is installed.
- wlan-ng-0.1.13
- kismet 1.4

OS=RedHat 7.2
wlan-card=D-Link 650

The D-Link card works fine if I just build up a connection to my AP. It seems, that there is also no problem if I activate the promicuous mode on wlan0: "wlanctl-ng wlan0 lnxreq_wlansniff channel=11 enable=true" returns the resultcode = success

If I now start kismet, my connection to the AP is broken - no more connectivity. Also I can't see any network or AP in the kismet console.

Do you have an idea ?

Thanx

Hi,
You the connection to your AP would be broken. As you've enabled monitor mode, the card will only receive and not transmit (hence it's called monitor :P).

Have you changed the capture type in the kismet configuration file (kismet.conf)? It should be like this -

captype=prism2

as your using a prism2 card (default is pcap AFAIK).

You are setting the card to listen on Channel 11 - Is this definatley the channel that your AP is operating on?

Perhaps if you post your configuration file we might be able to spot the problem ;-).

--Bovine.

Thanks Bovine,

channel 11 was ok. Only this stupid thing "captype" was missing. Sometimes it's usefull to read the config files too ;-)

Thanks a lot
