Re: rsh equivalent

Unix has a near-equivalent of the RSH protocol in rexec(). One difference
is the port number (rexec() uses 512, RSH uses 514). The other is that
rexec() always requires a password, where RSH has no mechanism for one.

We include a client program for rexec() in our DOS PC package, and I wrote
a primitive client program for Unix (that uses the library function). It
amounts to about 50 lines of code. We support the PC version because we
feel the security hole gets even worse when single-user PCs are involved.

As far as RFCs go, I don't know of any equivalent simple remote execution
protocol described by an RFC, and the only documentation for the 4BSD
protocols that I know of is in the man pages.
