I don't know how you come to the 3x conclusion, but looking at the code
I'd suggest that USED_NONSSH_PORTS as well as USED_PORTS either be
turned into a function or get updated within the while-loop. That should
reduce the amount of failures.

Considering the amount of perl  and code duplication we should consider
putting that into a function and sourcing it or rewriting the whole
thing in perl. Unfortunately currently time is very scarce for me.
