Thank you Carl, for your suggestion. You are correct. In this case, it would be possible to use mysqldump to create a file, then SSH to transfer it and then pipe it into the database.
However, I am interested in learning how to connect directly to the MySQL port, as in a second step of the project I am working on, various data from various servers will be handled. The 'dump to a file' approach, while fine in my little example below, will no longer be manageable in step two. Do you have any experience with stunnel or indeed, any other method of securely transferring data between 2 MySQL servers??
