Hello,

John Leach did mention starting to write a GNOME client for Kismet in
Python:

    http://johnleach.co.uk/words/archives/date/2004/08/

I don't know how far his work as gone into making Kismet's data available
from Python, but at least it looks like it's possible in theory.  It looks
like Kismet provides a server architecture that we might be able to take
advantage of.  In fact, there's already a project in Perl for this called
'gkismet':

    http://gkismet.sourceforge.net/

and there's nothing really tricky in there (most of the stuff in
Connection.pm and PacketWindow.pm look pretty straightforward).

gkismet reads very well --- they've abstracted things cleanly --- and
their source code makes it pretty clear how things work.  Once Kismet's up
and running, they open a regular socket to Kismet (looks like Kismet's
server runs on port 2501, perhaps?), and then start doing regular socket
communication.

There's a good Python socket HOWTO here:

    http://www.amk.ca/python/howto/sockets/

There's probably not much (except for human motivation) that stops one
from using Kismet from Python.  It would make an interesting project for
someone with time.  *grin*


Hope this helps!
