Before you can use openssh transfers (sFTP and rSync over ssh) you need to prepare the Home folder, and accept your server's host key.

(replace server.domain.net with the dns name / ip address of the server you want to use)

Open a command prompt, and browse to the Six Updater\tools\bin folder,for rSync, or Six Updater\tools\cygwin\bin for FTP, then:

ssh server.domain.net

If you receive an error like: Couldlike: Could not create directory '/home/SB/.ssh', press ctrl+c to cancel and manually create the folder mentioned after /home/,  into into the tools\home folder.for rSync, and tools\cygwin\home for FTP.

In In my case that means creating  Six Six Updater\Tools\home\SB

If the command is succesfull, the output should be as following:

The authenticity of host 'xx.xx.xx.xx (xx.xx.xx.xx)' can't be established.
RSA key fingerprint is xx.xx.xx.xx.
Are you sure you want to continue connecting (yes/no)? >>>>> ENTER yes  HERE <<<<<<<<<<

Warning: Permanently added 'xx.xx.xx.xx' (RSA) to the list of known hosts.

Enter yes, press enter, and press ctrl+c to cancel.

You're now ready to use the host: server.domain.net

Don't forget to specify your SSH private key in the software. For openSSH the private key should have NO file extension.
