With all this talk regarding port scanning, I was wondering what people are
using to monitor the unused ports on their firewalls.  I can visualize the
program which would do it, or even how to configure inetd to do the
monitoring, but puting ~65000 entries in my inetd file does not "light my
candle".

Perhaps an inetd like utility (anti-inetd) which reads the inetd.conf as
"don't watch on these ports" instead of watch on these ports as inetd does.
