Re: Some new SSH exploit script?

I totally agree the the last statement.

Full port scan + a banner grab... you then know it's an SSH server... whatever the port it is runningon

I think the point being made was that by moving the port that standard ssh/port 22 brute forcers and scanners would not hit you unless they did a full scan which I would expect a real hacker or targeted attack to do.

So yes in the sence of 'real' security it doesn't gain you anything. However in the sense of annoying script kiddies or bot bets it saves you the harrassment factor.

Running a service on a non-standard port yields zero increase in
security. That was my point.

I usually don't engage with ad hominems, but I'll attribute your tone
to a lapse in judgement. Prudent maintenance and hardening against
common vulnerabilities are of course necessary.

We've never been hacked, thanks. We use authenticated firewall traversal
for any non-public services. Public services are hosted in a DMZ.
