Hi,

I did an nmap scan on my computer itself on thee ways and realized
that both the cups and nfs services are in fact listening on the
external interfaces (last case as MYCOMP.MYDOMAIN):

Previously I could successfully stop smtp/ssh/squid to listen on my
external interface; would you please have an advise, how to stop the
above two to do the same?! I'm not afraid too much, because the fire-
wall is on, but...

Thank you,
Pelibali
