The MD87050 has a RS323 connection on the processor board close to the hard disk USB B socket. The labelling of the pins seems to be switched, at least in my version.


The MD87050 has a telnet server running which is accessible from its own WLAN and the WLAN it is connected to if any.


The root credentials are as follows:

  • User name: root
  • Password: 20080826

To back up all the devices insert a fat formatted SD card in the slot and run the following commands.

As seen in the list of MTD devices above mtd0 contains all data. Analysing mtd0.img with binwalk confirms this:
