assumption 1: the private key is .ssh/id_rsa.priv (on the starting machine).
assumption 2: you have to tell ssh (actually the ssh agent) which key to use.
assumption 3: .ssh/id_rsa.priv is readable only by the user.
assumption 4: someone has not configured the other machine to disallow keyed login (nuts, but could
happen. PubkeyAuthentication no?).
have you done
`ssh-add .ssh/id_rsa.priv`
before you ssh?
what does
ssh-add -L
and
ssh-add -l
give?
