How to debug "Auth fail for methods 'publickey,password'"

So no matter to which host I try to connect, I always get `Auth fail for methods 'publickey,password'`. Even for hosts that do not require a password.

Are there any debugging / logging facilities? E.g. like the `-v` option for the SSH client?

Start with clj-ssh's authentication path and its JSCH connection setup. Reproduce the failure against hosts with and without passwords, then determine whether logging or a verbose debugging facility is available; done means the authentication failure can be diagnosed through documented output or a clearly defined debugging path.
