Expect for Ruby

Hi everyone,

I've been assigned the task of automating one of our applications' intallation. One of the requirements is that this "automation script" should reside on a centralized location and should be able to remote connect to different boxes and run the installation package in each of them (via ssh for example). We want this script to work on UNIX.

I'm planning on learning Ruby to do this :-) The question I have is, do I need expect to automate the SSH connection so the user doesn't have to put in the usr and pwd? or ruby does that in the parameters of function that opens an ssh connection?

Many thanks in advance
