Access a Ruby server application

For security reasons, Ruby server applications are accessible only when using 127.0.0.1 as the hostname. To access the application, it is necessary to create an SSH tunnel by forwarding port 3000 on the Ruby server to port 3000 on the local host.

Refer to the FAQ for platform-specific instructions to create the SSH tunnel. An example of configuring the SSH tunnel using PuTTY on Windows is displayed below.
