It did not take me long, ok less than a day to get under the hood of the new NAS enclosure. D-Link was nice enough to run Linux on the box. As part of the boot process, the NAS executes can execute a script called /Volume_1/fun_plug.
A german developer has done all of the heavy lifting. He packaged up a shell script and additional software to make everyone’s life a bit easier. This includes allowing ssh access to the device and some handy applications including rsync.
