SSH SFTP connection + command + SSH Password



SSH SFTP connection + command + SSH Password

This is my first time connecting from WinSCP to a SFTP server and I have a few problems/questions.

Firstly I've got the process running when there's no SSH auth and the user just needs a password.

Now I'm running into a problem when SSH auth is required.

Also note that I can connect with FileZilla using a private key and the same user.

So I connect via the command script below:

option batch abort
option confirm off
open sftp://[user]@[domain] -hostkey="[hostkey]"
get -delete *.txt D:\Temp\*.txt

I know the username and domain are right as I can connect without SSH auth and the hostkey is right as I have matched it to the one in the log below.

Here's the log when I connect (a lot of info removed):

. 2014-02-05 10:54:26.703 Session name: [user]@[domain] (Modified site)
. 2014-02-05 10:54:26.703 Host name: [domain] (Port: 22)
. 2014-02-05 10:54:26.703 User name: [user] (Password: No, Key file: No)

. 2014-02-05 10:54:27.875 Disconnected: Unable to authenticate

Now my question is with regards to the lines:

. 2014-02-05 10:54:26.703 User name: [user] (Password: No, Key file: No)


. 2014-02-05 10:54:27.875 Prompt (7, SSH password, , &Password: )

First of all, should Key file be Yes if it requires an SSH key?

Secondly, is the password prompt for the user on the SFTP server or a passphrase for the SSH key? I turned off password required for the user in the SFTP software and when I generated my key on the server I didn't use a passphrase.

I've also loaded a public key against the user in the SFTP software, so how do I go about sending through the key from the WinSCP command line? I've added both the public and private keys to my .ssh dir.

Thanks in advance.
