Ahhh - that's a good question.  The truth is I am not sure.  It is a Maxtor 
Shared Storage device that is running a version of Linux as firmware, but 
have no idea which kernel version, nor what version of samba.  Is there 
anyway to remotely query the device to find out?  There is no telnet/ssh 
access to the unit - just a simple web interface that doesn't give any 
version information.

The firmware dates back to 2006-02-01, so I can be sure that it is based on 
technology older than that, but no ideas what version it might be.

Any hints on how to find out?

Tx,
