Why are you still messing with trying to SSH your books into eReader now that they offer their personal content uploading system?
But for what it's worth, there's also another way to do it if you have a computer and a wireless network.
Get some kind of simple web server application for your OS (or enable the web server your OS may already have built in). Put your pre-compiled eReader files on that web server, then do the "add" thing in eReader, choose "Another site," and enter the URL, using the LAN IP address for the computer. For instance, "192.168.2.101/my_ebook.pdb". It'll download it to your system just like any other e-book.
