Hi Daniel
I haven't yet used wireless on Debian but the general idea, I think,
is once you have the wireless thing running then you may be able to
pick up a list of wireless access points out there.  I have no idea
what package provides this.

These access points will use DHCP to allocate an IP address to your
wireless interface.   Any DNS will be sorted out at this time.

Most will not allow access - they will be protected in some way e.g.
password, MAC address restriction but iyou should be able to connect
to public access points.

I have no idea what iwspy does - the man page is unclear to me but it
looks like it is for access points.  iwlist might be more useful to
discover nearby access points.
