Thanks. We'll let you know when a new response is added.

Last I knew V5R1 was the minimum release level for secure FTP.

You may have to upgrade or look at other means.

    From the V5R1 Information Center:

    • New for V5R1, the File Transfer Protocol (FTP) server provides enhanced security while sending and receiving files over a untrusted network. FTP server uses SSL to secure passwords and other sensitive data during an information exchange. FTP supports either SSL or TLS protected sessions, including client authentication and automatic sign-on. Most SSL-enabled applications connect a client to separate TCP ports, one port for "unprotected" sessions and the other for secure sessions. However, secure FTP is a bit more complex. A client can choose a secure FTP port (usually TCP port 990), where the session is set up with SSL initially. However, a client can also connect to a non-encrypted TCP port (usually TCP port 21) and then negotiates authentication and encryption options. V5R1 FTP provides for both of these options.
    So, V5R1 would be the earliest to provide "secure FTP". But by now IBM i 7.1 is the earliest release that is available to upgrade to. I don't think that there are any systems capable of running anything as old as V4R3 that are also capable of upgrading to i 7.1.

    Other than "secure FTP", you could install the OpenSSH function if you were as recent as V5R3. That would provide ssh, scp, sftp and some other options. It's not at all clear if there is any way to get V5R3 on your system, though, unless (1) it's new enough to be capable of handling it and (2) you were regularly ordering the upgrades over the years and have the necessary series of upgrade media on hand.

    Thank you V5R1 is correct.  I finally found it yesterday from IBM software manuals search.  I am going to post this question next. I need to know how much it would cost to upgrade.  We have 49 that need upgrading 1 V4R2, 17 V4R3 and 31 V4R5.  Would you happen to know that answer?
