#1 summary of open ports

[Hannes]

what I am missing in this wonderful software is a
summary of open ports.
this would be handy, if you know that software X needs
port Y and you have no idea, to which protocol this
port belongs.

a concrete example: I installed a lan-browsing
software. and its docu said that certain ports
(137,138, and whatever) had to be open. if I hadn't
known that this belongs to the smb-protocol, i would've
had to check every of the guarddog protocols for the
mentioned ports.
