If you are talking about a situation where you are unable to use 
passwordless login like Peter suggested, there is a way to do it.

It is not trivial (i.e. `echo PASSWORD | ssh ...´ does not work) because 
`ssh´ tries to prevent this kind of thing because it is insecure; you 
have to trick `ssh´ into thinking its input comes from a terminal.  One 
such solution is provided by `sshpass´:
<http://sourceforge.net/projects/sshpass/>.

Use this script with care, if you have to.  If you can, use the proper 
"ssh-keygen / ssh-copy-id" method.
