Re: Or a simpler (than SSH) solution
"65536 to be precise.
So as a password it is comparable to a 3 to 4 digit numerical PIN"
Not quite sure the point you are making. I've already said that moving ports doesn't stop a determined attacker. After all in ~12 years of having sshd open on a unusual port I have had 1 attempt that found that port. Any number of attacks go for port 22. I take that as reasonable evidence that shifting ports has a noticeable effect.
I was merely pointing out that much of what we call security is in fact by obscurity. and passwords are no exception - that's why they need to be long and non-obvious.
Almost everything helps confuse or slow an attacker - hence I use a very unusual username and very hard password* , just one account is available and then for a couple of hours a day
*Example would be QspSbitjfphxtfjt1eUu which is never written down or remembered but generated from a memorized passphrase by a little c program and pasted. Of course I only use that sort of thing for important passwords like banking or ssh.
