I am trying to protect our IBM mainframe FTP service with SSL. The IBM people say that all FTP connections must be passive (initiated by the client). I have tried to set up CoreFTP that way and this is what I get. At the 227, I get a popup that says 'Cannot retrieve directory listing (server not responding). Would you like to try the directory listing in the opposite mode (active/pasv)?'. When I click Yes, I get this log. When I click No, it quits.
Has anyone been able to successfully connect to an IBM mainframe that has its FTP service implicitly protected by SSL?
