OS/2 provides secure telnet to AS400, but setting it up is a little hard. I'm finding directions for the i-Series, but some of the rest isn't obvious. Like a lot of things in the era, Java 1.1 seems to be a requirement.
\IBMGSK40 is required, too. (Ever wondered what it was for?)
Mensys has moved a critical file from \IBMGSK40 to \ecs\bin\GSK4IKM.CMD, so that needs to be moved back.
Has anyone done it? I'm not really familiar with AS400.
