It sounds like you haven't setup password-less communication between your
nodes.

Can you "rsh node1" or "ssh node1" and not be prompted? If not you need to
setup password-less rsh (usaully .rhosts) or ssh. You can tell which one
mpirun (or change it) is using by the value of RSHCOMMAND (at least in
the 1.2 version) in mpirun.
