Secure FTP in an SSH environment is available on the IBM i.
I would start with reviewing information on Scott Klements site, especially the presentation he did at the NEUGC conference. That can be found at
Then I would download the Redpaper “Securing Communications with OpenSSH on IBM i5/OS”. With the use of these resources I have been able to setup file transfers between an IBM i5 and a Unix server in a automated/scheduled fashion.
Hope this helps,
Since secure FTP (FTPS or FTP over SSL) and SFTP (SSH File Transfer Protocol) are two very different things, you need to make very certain your understanding of what is needed.
FTP over SSH can be tricky and is different from the two possibilities above. It involves tunneling an otherwise normal FTP session through a SSH connection. Since FTP may use multiple ports, it isn’t straightforward.
However, straight SFTP can be easier using the advice that Bill gave previously.
The fundamental need is to know for certain what is being asked for. Perhaps the single most important piece of information will be the port that will be required. That will help determine which of the possible interpretations of “secure FTP” is the right one.
