Hi, I am working as a wireless LAN developer at LANCOM Systems, Germany.
I am currently working on transforming one of our access points into a wireless sniffer, and I found the AVS capture frame format (as defined on http://www.shaftnet.org/~pizza/software/capturefrm.txt) suitable as format to store the capture results. For the moment, I have created a small 'dummy' test file with just a single frame, and have used Ethereal 0.9.14 to display it. The display works fine, with a small problem: the frame's signal strength is interpreted as an unsigned value, and not as signed as the format definiton states - which looks rather weird if one has signal strength values smaller than 0 dBm 8-) I have taken a look into 'packet-wlancap.c' and after changing the definition of the 'ssi_signal' field from signed to unsigned (lines 163+246), ethereal's dump looked as I expected it. I'm not entirely sure whether this is actually a bug or the header definition I have is outdated, I just thought I should mention it. Best regards Alfred Arnold LANCOM Systems GmbH, Germany
