Subject:Unable to capture any packet
Date:13:18:23 07/02/2008

Hi,

I am not able to capture any packet using kismet-2006-04-R1.

My setup is -

Gateworks BSP 0.7
Buildroot
madwifi-r3008
Linux-2.6.21.4
Senao radios

When I run kimset_server I am getting -

Gathering packets...
<< after some time >>
Didn't detect any networks, unlinking CSV network list.
Kismet exiting.

Please note that I used the same kismet version successfully with -
madwifi-0.9.2
Debian sarge 3.0
Linux-2.6.18

With the OS migration it is no more working.
I can not change the kismet version as I have some enhancements on it for my project.

When I debugged the code I found it breaks (returns) for every packet captured, at -

In pcapsources.cc -
if (callback_header.caplen < hdr->it_len) {
packet->len = 0;
packet->caplen = 0;
return 0;
}

I printed both the numbers and found callback_header.caplen = 133 and
hdr->it_len = 5888.

Anybody has any pointers, please share with me.
Thanks for your time.
Regards,
Saurav
