With

val settings = SSHOptions( host = "localhost", username = "flyrev", identities = List(SSHIdentity("/home/flyrev/conf/ssh_keys/id_rsa")) )

SSH.once(settings) { ssh => print(ssh.execute("""echo "Hello World from hostname" """)) } }

Any idea what's wrong?

So there was a problem with authorized_keys. I guess the confusing thing was that it insisted on trying with a password. Is there a way of disabling that altogether, giving me "public key authentication failure" instead of that other message?
