Uhm, see if ssh-agent is running on ernie. Also, you could have
simplified this by using:
$ ssh-keygen -t dsa
$ ssh-copy-id -i ~/.ssh/id_dsa.pub jack@ernie
That would have done steps 3-6 you did manually. See "man ssh-copy-id"
for details. You do know you only have to do the "ssh-keygen" once and
use the same id_dsa.pub on all your remote machines, right?
