rsync - Aug 2004 - without ssh prompt

When I ssh-keygen a passwordless key pair for root and give the public key 
to openssh server(sshsrv), then it is ok to 
	# ssh root@sshsrv

But when I generate a password key pair for root and give the public key 
to openssh server(sshsrv), then I fail to 
	# echo "rootpasswd" | ssh root@sshsrv
and get the follow message:
	Pseudo-terminal will not be allocated because stdin is not a terminal.
	Enter passphrase for key '/root/.ssh/id_rsa':

How can I login into ssh server automaticly, without getting the prompt?	

Best Regard

This is an ssh question, so you're better off asking it on the ssh
mailing list.  However, I think you're looking for the ssh-agent
command.  See also the keychain project for a way to maintain an
ssh-agent over multiple logins.

As for why the above command does not work:  ssh not prompt for a
password on standard input, so you can't pipe it a password on stdin
(standard input is being forwarded to the command that it runs on the
remote host).
