Oh, and by the way... Do you have two physical, separate ethernets?
Because otherwise you might be in even more trouble, as you have two
ethernet interfaces defined on MOE, and they both see LARRY. If you
actually have two ethernet networks between the two machines, then
everything is fine. Otherwise you are actually very messed up.
