 - At the moment, SSHTunnel uses only the password authentication methods. Therefore, it is currently not possible to use e.g. a certificate, etc. Nevertheless, the implementation of this feature is possible.
 - The configuration must be provided by using the command-line arguments. It is currently not possible to use e.g. a configuration file.
 - You can avoid the password argument if you prefer to provide the password on demand.
