rsh reads from its tty, not from stdin. You can work around this by
using a program called `pty'; it opens a pseudo tty and runs the program
given on its command line on it. The source comes with Stevens' book
_Advanced Programming in the Unix Environment_. Unfortunately I don't
have my modified rsh anymore that worked on Solaris, as the stock rsh on
at least 2.6 had some quirks that prevented it from functioning.
Disclaimer: the above is all from memory, and it's been a while since
I last had to do this. The major problem I had to solve was rsh not
wanting to run without a pty (i.e., from cron).
Good luck,
