If you are being prompted for a password, then you have not setup your DSA
key properly.
Double check that you can do the following:
ssh some_other_node uptime
and see the output of "uptime" from the other node without being prompted
for a password or a passphrase. When that works, you'll be able to
lamboot.
Consult the SSH documentation about how to setup the keys correctly.
