The reality is that only script kiddies start out by trying 22 (and I *do* mean script kiddies - I've seen attempts to ssh in that were obviously from warez, man, where they were too stupid to fill in ___ with a username, or salt. All the others, I figure they don't need to be major league, just someone with a clue, who'll run a scan; in fact, I'd expect them to run a scan just to see what IPs were visible, and I know that if I was writing a scan, I don't assume that I'm *so* brilliant that I'm the only one to think of scanning ports < 1k while looking for systems that I might hit. mark
