You're missing a call to SSL.File()->accept(), otherwise SSL.File won't 
know if it is supposed to be the client or the server. Considering that 
your code seems to be using blocking I/O, you probably want to call 
set_blocking() (SSL.File defaults to nonblocking mode) as well.

     ssock->set_blocking();
     ssock->accept();

And here you need the corresponding call to SSL.File()->connect().

      ssl->set_blocking();
      ssl->connect();

You may want to take a look at the code in SSL.https and SSL.Port.
