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? ---

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 Len S.
