>Description:
rsh commands to 2.2.7-RELEASE machines that can handle more input
will terminate immediately
>How-To-Repeat:
        rsh 2.2.7HOST /etc/rmt
        rsh 2.2.7HOST /bin/cat
        rsh 2.2.7HOST /bin/sh
        rsh 2.2.7HOST dd ...

basically any remote shell that can accept more input.
