take a recent phpBB worm Santy for an example. worm seaches
automatically targets via google - it searches
viewtopic.php. if, for an example, you change that file name to
something else (and also all the referrings inside the phpBB so that
everything still works), then Santy does not find you phpBB as a
target. this is only an illustration to my point.

i wrote my post because you say "the non std port advice is not worth
much". i have lot of cases, when non standard configuration reduces
first impact greatly. of course you shouldn't rely only to non
standard ports/configuration, but it is not totally worthless - it
often helps you a lot.
