openssh unix dev - Jan 2002 - Passing a password from a program to ssh

Hi all

Probably this question was asked before, but I didn't find anything 
in the FAQ or in the archives.

I've written an programm that connects to a SSH server and 
communicate over the SSH protocol with a SSH subsystem. SSH now shows 
a prompt where the password should be typed in. If an error occurs 
(protocol error or so) the programm must reconnect to the server and 
reestablish the connection. If I fork the SSH program again, it will 
require the password to be typed into the console again. But as 
daemon there is no shell and it will fail.

So, is there a possiblilty to pass the password e.g by using stdin or 
any other method which is secure?

Why not use ssh-keygen and use that so you don't have to worry about
entering passwords?

don't use password authentication or write
a ssh-askpass replacement and set SSH_ASKPASS
