I see what your saying about the 'data' directory and I re-did it
without changing to the 'data' directory and get the same error.  See
sample code below;

irb(main):006:0> ftp.login('bruskeftp','35sumler75',nil)
=> "230 User bruskeftp logged in.\n"
irb(main):007:0> files = ftp.dir('data')
Net::FTPPermError: 500 Invalid PORT Command.

I hate to bring up the "P" word but I did the same thing using python
and had no problem.  Sample code below;

>>> ftp.login('bruskeftp','35sumler75')
'230 User bruskeftp logged in.'
>>> ftp.dir('data')

Unfortunetly, I am really new to Ruby, and really wanted to start using
it for some production stuff.

I want to thank you for your time and help if you happen to think of
anything else I will give it a shot.
