Re: nmap-7.60 on Mac OS X - ssh-publickey-acceptance not working

[Daniel Miller <bonsaiviking () gmail com>]

As we determined today on IRC, the private key file was
passphrase-protected. It is a shortcoming of the current libssh2 bindings
that we do not return any sort of error information after a failure. In the
meantime, I've just added the ability to supply passphrases in the
script-args for ssh-publickey-acceptance in r36982. Hopefully we'll be able
to get error reporting added soon.
