That will not work because, however, ssh doesn't read the passwort from stdin 
(like ftp).

But there's a way to use ssh without a password-request:

On your local machine create a key with "ssh-keygen -t rsa" (use empty 
passphrase). After that copy the public part of the key (located in 
~/.ssh/id_rsa.pub) to your remote machine under ~/.ssh/authorized_keys).
Now your script should work.

Hope it helps,
Robin
