Why does ssh require a password on new machine?

[stan]

I jst installed a new FreeBSD STABLE box, and it seems to insist on a
password when I ssh from an existing machine. I've added the (I think)
appropriate entry to the ~/s.ssh/known_hosts fiel on the new machine.

Here is ssh -v on a mcahine that works:
