You might want to look at the "rex" service in SUN's RPC package.
This is something quite similar to rexec(3) and rsh(1).
What I mean is : it also doesn't provide a virtual terminal for your remote
processes.

If you have access to SUN manuals, look at on(1c), rexd(8c), and rex(3r).
If not, you could get the idea by looking in the RPCSRC 3.9 package,
which was recently posted to the net (comp.sources.???).
It is also accessible via anonymous ftp and via Email from the archives of
Sun-Spots.

If you need better authentication than BSD's r*, I think this may do :
the rex-system uses the same "UNIX-style authentication" that the entire RPC
package uses.
If you have a SUN or a 4.3 system from Mt.Xinu, you should be able to use it
right away.
