If you have to use a password, you will need the input to ssh connected to a
tty. The easiest way is to use Expect or Perl/Expect to handle the transfer.
Both of these create a pseudo TTY that the ssh command gets.
The reason your getting the prompt when piping is ssh reads from the tty instead
of stdin for security reasons. It is the same problem you would get is you
tried piping input into the passwd command.
