At layer 4, socket, it is the "shell" service rexecd "shell 514/tcp cmd".

At layer 7, application, it is the rmt application originally designed for
rdump, ufsdump and so on.

So you must have the shell service turned in (x)inetd and the rmt
application installed (it is by default on most systems), the permissions
opened so you can do "rsh HOSTNAME pwd", and the target .cshrc not broken
so the response is nothing but the home directory without any errors or
other output.
