Nas326 Clean CLI Shutdown

Mijzelf

Thanks again. Thought about the serial interface but I'd have to set up a console.

I'll have a look at your code, ta ... and I hadn't thought of telneting from the box itself :-) Worth a play.

And while I was contemplating my fate I knocked up a "Network Monitoring Box" on an old RaspberryPI 1B that was sitting idle in my bits box. I put "raspbian stretch lite" on, apt installed loads of network tools. I wrote a small service that pings the network boxes and WOLs & telnet halts my Zyxels on "network idle". It only took a couple of hours to knock up and it could be a fun tool. And I would be able to remove my WOL daemon from all boxes and my watch&start code on the router (for the TV's - no WOL on a TV!).

I put a listing at the end for a hoot! Surprisingly it worked!! After 3.5 decades in the business (& retired for 10 - yup I'm an IT dinosaur!) I never trust my own quick code to do that!!

I'll still like to know what the disk issue is ... may be its some form of incompatibility with the hard drives? 2 * 6tb Seagate ST6000VN0033 IronWolf Nas. As I say the same code is fine on a NAS325v2. Same USB stick model but different hard drives. The firmware is updated of course (eg PHP is not complete on the 325 - no PDO, but ok on 326!) so it may be an issue in the 326 firmware.

# Rodina.Dum Network Monitor Service
# This service pings the Rodina.Dum Network Ip address for media and
# pc clients in the range 192.168.11.30-192.168.11.59
# When any of these clients appear on the network the server will
# initaiate a WakeOnLan pings for the 3 NAS servers at
# 192.168.11.20 192.168.11.21 & 192.168.11.22
# If no IP addresses in that range respond within a 10 minute session
# WOL pings will be stopped  and the NAS boxes closed.
# Note that 192.168.11.20 & 192.168.11.21 are Zyxel Nas boxes
# and require manual closing via a telnet command. 192.168.11.22 is a
# Buffalo server and self closes when WOL pings are not received
