ssh without password

[Matt Patterson]

I think what you might be looking for is a key agent (ssh-agent). I had 
a job where we logged into the cvs server via ssh without passwords. We 
were assigned key pairs that we placed in our home folder and run an ssh 
agent. It seemed like ssh new to talk to the agent and authentication 
was handled.

I dont know much, but hopefully this points you in hte proper direction.
