First start the USB over Network Server:
$ sudo /opt/ftusbnet/sbin/ftusbnetd
Normally, the server starts in a non-debug mode and is not daemonized. In this mode you can stop the server by pressing+ in your terminal window.
To start server in daemon mode use -d option. You will normally need this option in shell scripts (e.g. if you'd like to start the server every time on system boot). To learn how to run the server automatically on system start please refer to your Linux distribution manual.
To see the list of all supported options, run:
$ /opt/ftusbnet/sbin/ftusbnetd -h
Daemon settings initialization can be done with a configuration file. Further daemon management can be done via the graphical user interface application or command line utility.
