Customizing the rlogind daemon

The rlogind daemon validates rlogin requests. If you choose to have the rlogind daemon run with a user ID other than OMVSKERN, you will have to customize it.

Example: To customize the rlogind daemon so that it runs with a user ID other than OMVSKERN (for example, RLOGIND), issue the following:

ADDUSER RLOGIND
DFLTGRP(OMVSGRP) OMVS(UID(0) HOME('/')
PROGRAM('/bin/sh')) NOPASSWORD

The NOPASSWORD option indicates that this is a protected user ID that cannot be used to enter the system by using a password or password phrase. The user ID will not be revoked due to invalid logon attempts.

Tips:

For all the other setup steps required for rlogin, see Setting up for rlogin.
If you are writing or porting your own command to process login requests, the shell interface to rlogin is the FOMTLINP module, which is documented in Modules for the login and logout functions. FOMTLINP has many parameters that can be used to tailor the rlogin processing. FOMTLINP is the login function and FOMTLOUT is the logout function.
