And don't bother with "Shields Up". If you want to do a portscan, use
something like nmap.

Since this is a basics list...

Now, let's qualify that a bit...  Not everyone is technically savvy
enough to know what to do with such a statement.  Nmap requires you
have a system to run it with/on.  That also requires (or should to be
somewhat valid/useful) that you have this run externally.  So you need
to have a friend outside of your own "personal network" to scan you
and provide you with the results.

Loading something on a PC in your own little network is good for
learnings, and you can definitely port scan systems in your own
internal network, but I think the goal should be to port scan outside
of your private network beyond your ISP access point so you know what
*everyone else* can see...

In the absence of this, using *something* is better than *nothing*...
