Moving Users from one box to another

[Monkey Monkey Monkey]

I am building a brand new linux box, and I need to move all the users and passwords from an old box. Is there some tool that will do this, or do I have to do it by hand?

If I have to do it by hand, what files do I move. Both machines are running Mandrake 7.1

thanks
