This is a simple daemon for the D-Link DNS-320L NAS system.
It was developed on knowledge gained from reverse-engineering and spying on the original D-Link system software. Parts of this work are based on fan-daemon.py by Lorenzo Martignoni.

On bootup, dns320l-daemon is executed and runs as a deamon. On startup, the daemon can optionally read the RTC and set the system time to the RTC time. It also sends the DeviceReady command to the MCU so that the Power LED stops blinking. Afterwards, it goes to fan control loop.
If the daemon is killed (e.g. during system shutdown), it sends the DeviceShutdown command with a timeout of 10 seconds to the MCU. After 10 seconds, the MCU kills power.
For normal operation a socket server on port 57367 is provided. You can connect with any telnet client to this port and work with the device. Just type "help" for a list of available commands.
Either compile the software on your NAS by typing "make" or cross-compile it from your host computer. Put the binary to /usr/bin and the config file to /etc. Adapt the parameters to your needs, leave to defaults if unsure. A systemd unit is provided which can be copied to /etc/systemd/system and enabled by running "systemctl enable dns320l-daemon"
