The latest whereami has some stuff for sniffing wireless networks in
it. It attempts to configure the WLAN to a particular SSID, waits 1
second, and then checks for that ssid with iwgetid.
This is kind of simple, and I would welcome some help extending the
handling of WLANs. I only have the one WLAN myself, so I wrote the new
script when I was at a conference recently where there were several
more.
Cheers,
Andrew.
