In the other ssh, this means that host2 does not accept your
credentials, and is in the position of asking for a password/passphrase.
That is, if you ssh first to host1, and then try to either ssh or scp
from there to host2, you'll see an interaction.  Since there is no
controlling tty when doing dereferenced scp's (as above), the process
fails.

Perhaps it's time for you to try ssh-agent, along with installing the
authorized_keys on affected servers.
