Telnet can go over ports 992, SSL. You’ll need to set up the certificate for the telnet server, then change the telnet server to only use SSL (or both 23 and 992 if you so desire) Been that way for quite some time.

I really haven't been paying much attention, but am I to understand that the latest IBM Midrange hardware has SSH capability?

It has an SSH Server and possibly an SSH client

Including 5250 over SSH?

No. This was and stays a telnet-only thing. Ssh is solely giving you access to a UNIX style shell on IBM i, akin to qsh, but without the limitations of 5250 in regard to something coming from a character based world instead of a forms based.

You can use the port forwarding facility of ssh to forward an insecure telnet (23) port to a remote client over an ssh secured channel, though.

:wq! PoC
