When I try to run nmap on my Zaurus (pdaX r198, Ambicom WL1100C wireless, custom-built pcap), it says

Starting Nmap 4.20 ( http://insecure.org ) at 2007-10-14 12:14 UTC
pcap_open_live(wlan0, 104, 0, 200) FAILED. Reported error: live packet capture not supported on this system.  Will wait 5 seconds then retry.
caught SIGINT signal, cleaning up

What causes this? Kismet works fine. Do I need to put the card into monitor mode or something (it's just connected to my wireless now).

Strace could take the guesswork out of what's going wrong because you can see the calls and all from just before it messes up.

Have you used it before? I tend to increase the output string when I run it to make sure it doesn't cut off anything important. My strace for this would look something like:

strace -f -v -s 200 -o /mnt/card/nmap.strace nmap &

You could have it put the results wherever you wanted and call the output file after -o whatever you want, I put mine on SD card. The number after -s is the length of each diagnostic string. If a line is longer than that, it gets truncated and I think the default is something like 30 characters IIRC.

Just try it...you could post the last 50-100 lines of output to get help interpreting?
