Just for grins and giggles, I created an SSH private key/public key
pair. I can now use PuTTY to logon to Linux without using my Linux
password. Instead, I must use a "Passphrase". What have I gained? I did
replace my password with a passphrase, but how is that more secure? I
don't see a way to say: "This passphrase must be used when doing an SSH
from that incoming IP address." Am I missing something? (very likely). I
could use a different private/public key for each server that I use SSH
with, I guess. But I've only got one server, so far.

Oh well, it was a "learning experience", I guess.
