Hi,

Two problems, possibly related:

 1) When I quit dstumbler I get an error message at the
bottom of the screen:
 "error: unable to ioctl device socket: Invalid argument"

 2) I can't seem to detect a simple WLAN consisting of two
PCs in Ad-Hoc mode, with 40-bit WEP. The dstumbler screen
stays blank. Yes, I understand that dstumbler relies on AP
broadcasts and Station discovery requests, but should it not
see some sort of activity?  (tcpdump works)

Where do I start digging?

Hi Louis,
On the first count - I don't know.
Second count:
Make sure you've made prism2ctl and issued the -m switch on your wireless
card.
