Don't have any ports open that you don't need, avoid DROP (use DENY),
leave yourself pingable.  If you don't need to be running a service,
don't do it.

Hack you?  Impossible.  Crack?  Depends on how well you make yourself
look undesirable.  (Please learn the difference between hacking and
cracking, it's a very important distinction.  You can look it up in
the jargon file, http://ursine.dyndns.org/jargon/)

Do not buy a cable modem off Ebay under any circumstances.  These
things are brutally easy to fry with line surge off the cable line,
especially if you're in a lightning prone area.  If you still want to
buy your own cable modem, get a 3Com OfficeConnect.  This modem should
work on most cable systems.  Call your cable operator to see if they
can provision this modem beforehand.  If this particular model isn't
available or your cable operator can't handle it, you're better off
leasing a modem from them.
