Wireshark · Ethereal-users: Re: [Ethereal-users] wlan : PCMCIA Cisco Aironet 340 Control Frame Capture

[P Laurent <laup_no@xxxxxxxx>]

 

I use now a Prism2 card (Compaq WL100) with the wlan-ng driver.

I use the following command to put the card in rfmon:

wlanctl-ng wlan0 lnxreq_wlansniff channel=[#channel i want to analyse] enable=true wlanheader=true and then I run ethereal

...and it looks like i still do not get control frames as I should.

is this command ok?Is there another way to put the card in monitor mode? or..?

Some drivers and/or card firmware will not pass the control frames to
libpcap for processing. I know that the orinoco_cs drivers will report
everything but control frames while in RFMON, while the wlan-ng and
hostap drivers will report both management and control frames.

Not sure about the Cisco drivers, but if you really want control frames,
I'd go with a Prism2 wireless card and the wlan-ng drivers.
