Steps for customizing the uucpd daemon

Before you begin: You need to set up the uucpd daemon to /etc/inetd.conf.

Example: Add the following lines to /etc/inetd.conf:
uucp  stream  tcp  nowait  omvskern  /usr/sbin/uucpd
uucpd -l0

If you want to have the uucpd daemon run with a user ID other than OMVSKERN (for example, UUCPD), you need to decide what the new user ID will be.

Perform the following steps to customize the uucpd daemon.

  1. Change the line in /etc/inetd.conf to:
    uucp  stream  tcp   nowait  uucpd  /usr/sbin/uucpd uucpd -l0

    _______________________________________________________________

  2. Define user ID UUCPD to RACF®.
    ADDUSER UUCPD 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. In this case, you are defining the UUCPD user ID without a TSO/E segment.

    _______________________________________________________________

When you are done, you have customized the uucpd daemon so that it runs with the UUCP user ID.
