You changed directories into ‘data’, and are then trying to list a
‘data’ dir?

FWIW, all the above worked fine with me using Ruby 1.8.5 on Windows,
going to a known-working and accessible FTP server. Smells like either a
firewall/port-blocking issue, or a double-NAT issue. To be sure: can you
FTP from the command line/shell just fine?

all goes fine but at this point I have tried all of the following and
get the same errors

try

ftp.passive = true

files = ftp.list(‘data’)
files = ftp.dir(‘data’)
files = ftp.dir(dir = nil)
files = ftp.nlst(‘data’)

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’)

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.

Looks like a passive ftp mode problem versus standard ftp using port 20,
and 21. See if at the api you can turn passive mode on.

Hope that helps.

I’m sorry I retried the setting of passive and that DID fix the
problem.

I want to thank you all for your time and your help and I hope someday
to be able to help others out on this ng.

Thanks
