Hi oxygen8,
I had a chance to study your website and the instruction:
* I failed to enable ssh access using the GUI tool (I can execute all steps without error, but somehow got ssh "connection refused"), so I tried the hard way below.
* I tried to use the command line tool, but for some reason I failed to change the sshd_config. I tried to "cat /etc/sshd_config" and the config remains unchanged
* I use the command line tool to do smartctl command on all HDDs and I don't see anything strange from the output. The output seems truncated though
* What should I do next? Should I run the smartctl test? I didn't do it because the NAS is in the checking mode.
BTW, when the NAS is still powered on, it's running some kind of diagnostic mode with blinking purple LED. The NAS page says "RAID Array 1 | Status: Checking ( 2.0 % Complete)".
I never see it complete 100% because after a while (few minutes, sometimes few hours) it powers off by itself.
Thanks a lot!
