sure, but 99% of the time the machines attacking your server are zombies
that do not care to do a full portscan. i suppose the purpose is to
find other misconfigured, easy-to-hack computers on the network. by
putting your services on non-standard ports you get rid of these
mindless drones and don't pollute log files with useless garbage.

now if somebody _does_ actually target your server in particular then
this is definitely not the solution.

anywayz, putting things on non-standard ports helps a lot, and is
one of the first and easiest security measures an administrator
may consider.
