If you're having trouble starting kismet from the menu try editing
/usr/local/etc/kismet.conf.backtrack
it starts up as I would expect now on my BT3b HD install.
Originally I put my source line in kismet.conf and it ran from command line but when I tried the menu link it removed my source line from kismet.conf - I assume my kismet.conf was being overwritten (with kismet.conf.backtrack) when kismet was being started from the menu. Not really looked into it as putting my source line in kismet.conf.backtrack solved it for me.




good luck
