yes except for the fact that i don't have a fax machine and the number
is incorrect anyway :D

ok this is really neat!
we did the scan and found what the open ports are.
so the first one we changed was the ssh.
then a friend said he assigns ports that are not used in /etc/services,
so i presume this means for instance if we change the http port, we'll
have to tell our http server to do business on that port?
is this what you mean by ensuring that the program listening on a port
is properly secured? or is there something else?

ok we'll look into this further. we really don't have too many web
forms and the forum software we use is punbb which i think they
(rickard et al) take good care of.

i think this is such a situation. i think the person thought i'd be
astonished that he was able to pull my first and last name as well as
my address out of a whois search and show them to me :D
and by showing me that he can use words like backdoor and BSD, no doubt
i should step back and bow to his level of expertise!
still, i see this as an opportunity for my son and myself to learn
something we really haven't paid much attention to, so we're going to
do it!
thx for your help bill!
