The Secure Shell protocol used by Tectia Server for IBM z/OS provides mutual authentication – the client authenticates the server and the server authenticates the client user. Both parties are assured of the identity of the other party.

The Secure Shell server host can authenticate itself using either traditional public-key authentication or certificate authentication.

The Secure Shell client users can authenticate themselves using password, public-key, keyboard-interactive, or host-based authentication. These authentication methods can be combined or used separately, depending on the level of functionality and security you want.

This chapter gives instructions for setting up non-interactive authentication for server and users using public keys. For information on the other authentication methods, see Tectia Server for IBM z/OS Administrator Manual.

Most of the examples in this chapter are executed from Unix shell (for example, OMVS shell), but the same commands can also be run in JCL using BPXBATCH.
