[Nut-upsuser] Synology NAS is shutting down Ubuntu servers after very brief power outage (fwd)

[Todd Benivegna]

upsmon.conf on server:  https://pastebin.com/z4CrUTxb
nut.conf on server:  https://pastebin.com/540ShZH7
Permissions for /etc/nut:  https://hastebin.com/qecolodapi.diff

On the Synology (I didn’t edit any of these files):
ups.conf:  https://hastebin.com/dedereqizi.shell
upsd.conf:  https://hastebin.com/pupeseweda.css
upsd.users:  https://hastebin.com/ocenamecex.cs

I don’t think I am able to run that script.  If you can, I wouldn’t know how.

Please let me know what you think.

Thanks for all the help!

Todd

I then installed NUT on all three servers. In nut.conf I changed MODE to "MODE=netclient".  I then added my MONITOR line in upsmon.conf. on all three.  Looks something like this:
