can't log in and don't know what I am doing?

I am trying to transfer files from my old computer to my new computer and can't get logged in and I am unsure on what I am doing?

How are you trying to login? Do you have an SFTP/FTP server installed/configured on the other machine? Can you login using any other client?

Maybe this can help you?
