    Not to mention that you already mentioned that an rsh without a command works,
    so that is a suspect solution...

    Have you tried any other commands besides 'date'? Try 'rsh aixbox /bin/ps' or
    something else with a fully qualified path. You may also want to try
    redirecting stderr to stdout: 'rsh aixbox /bin/ps 2>&1'. If your remote user
    runs (t)csh or bash or some other shell that sources a dot file with rsh (korn
    shell does not), it may be an issue with your dot file(s).

    User name and correct .rhosts/hosts.equiv entries are what matters - the
    password is not used and neither is the UID (until AFTER the connection is
    established).
