OpenSSH Key Storage

[Nicolas Williams]

IMHO, the issue is dealing with forwarded sshd's. So the client really
ought to have a separate option for specifying the name of the expected
server host key separately from the host/port to which the client should
actually connect.

E.g.,

ssh -N the_server_I_want -l remote_user -p the_port the_host ...

No ambiguity.
