Yeah, I checked for nmapfe on synaptic right after reading your initial
report.  ;-)  I can't make heads or tails of the user interface yet, but
I'm working on it.  Traditional problem of documentation applies.

Got any pointers (or pointers to a list of pointers, perhaps)?

Well, I have an additional layer between what my machine exposes to the
world and the actual world.  My external router exposes precisely two
ports to the outside world -- I've verified this with an intensive port
scan both from within and without my local net -- and those two ports
are shipping to an application I know reasonably well and can monitor
the behaviour of anyway.  It is otherwise stealthed to the outside
world.  (I'm a newbie to Linux security, not to security in general.)  

This gives me a bit of breathing room in learning Linux security (I
hope).

Oh.  And I have the dubious "comfort" of the Great Firewall.  That
doesn't add a lot of security, though, for anybody.  ;-)
