I knew I should have mentioned something about that :) Yes, I could use SSH, but then I'm back to the whole interactive thing. I could have my script basically do an expect with ssh and login (but that kind of defeats the whole security thing), or I could have shared keys that allow them to not enter a password (I saw a good, short discussion on this topic here as I was looking for ideas). I guess I'd like for the end user to click a button and have it dial.
And yes, rsh is BAD and ssh is definately GOOD.
