You will have no luck that way. rshd expects the already opened socket
connection on stdin/stdout/stderr. This is what inetd does for it's
child processes. rshd isn't intended as a stand-alone daemon.
On the other hand: What problems do you encounter? Are you using
the latest version (1.3.2-8)? It contains a fix for rshd which avoids
a possible crash on startup.

That's the same. `args' begins counting with 0.

You may do this. Some applications work different when they are
started with another argv[0]. `rsh' for example expects to be named
`rsh' (aka argv[0] == "rsh"). Otherwise it treats argv[0] as the
name of the host it should connected to.
