Nut upsuser - Jun 2017 - Apple Mac slave

> I see upsd and the first upsmon are running as "root".  They are

Apparently Synology has implemented it standard like this. 

Upsmon.conf on the Synology NAS:

RUN_AS_USER root

I suppose this needs to be changed from a security point of view.

completely, leading to a crash?
Good question and I don?t know the answer yet. 

This is what I can find about safe-mode means that all services are stopped and
volumes (unmounted). So I quess it is not completely shut down and wil draw
still power.

I have to examine this.

I don?t know where to search to answer this. The delayed UPS shutdown means that
Synology NAS will turn off the UPS after the delay?


ups.delay.shutdown Interval to wait after shutdown with delay command (seconds).
Shutdown of what?  I don?t know what is means.

On the Mac I have in upsmon.conf 

MONITOR ups@<ip address> 1 <user> <password> slave

2. On the NAS, use command

  upsrw -s battery.charge.low=80 -u upsmaster -s sekret UPS

to set the low limit very high during testing.  This will speed up your testing.
You can reset it to something else later.

When I run this command:

upsc ups at localhost:



battery.charge.low: 10


The commando upsrw cannot be found on the Synology NAS?

Yes, See the User Manual http://networkupstools.org/docs/user-manual.pdf 
chapter 6.3 "Configuring automatic shutdowns for low battery events".

The NUT documentation is not always clear, and it looks as if the Synology 
is even less clear.  You must distinguish carefully between "system 
shutdown" and "(delayed) UPS shutdown".  The UPS is turned off
_after_ the
system.  There is a delay between the moment the upsdrvctl shutdown 
command is given and the moment the UPS shuts down.  The default is 20 
seconds, but you may have to increase this.

I understand from 
https://tellini.info/2014/09/connecting-a-synology-diskstation-to-a-nut-server/ 
that the NUT configuration is hard coded into the NAS, and I suspect that 
the configuration is more or less broken.

You will need the utility programs upsrw and upscom which are part of NUT, 
but they should be available in the Mac.

I have read 6.3. I don?t see the delayed shutdown here, more about low battery
events

What I notice in the upsmon.conf on the Mac which is the slave:

POWERDOWNFLAG /etc/killpower 

I don?t think this is necessary? 

When I start on the Mac : sudo upsmon -D 

I can see: 

sudo upsmon -D
Network UPS Tools upsmon 2.7.4
kill: No such process
   0.000000	UPS: ups@<ip address> (slave) (power value 1)
   0.000791	Using power down flag file /etc/killpower
   0.001240	debug level is '1'
   0.013266	Trying to connect to UPS [ups@<ip address>]
   0.014898	Logged into UPS ups@<ip address>

There is also a message:

kill: no such process. what does it mean? 

Also I changed on the Mac, upsmon.conf :

SHUTDOWNCMD "/sbin/shutdown -h +0? which was before SHUTDOWNCMD
""

SHUTDOWNCMD ?? Didn?t make sense to me.

upsrw is available on the Mac:


upsrw -s battery.charge.low=80 -u upsmaster -s sekret UPS

I suppose I have to use -u for user? Which user? and -p  for password? 
What does -s sekret UPS means? -s means variable to be changed but I don?t know
which variable this is, sekret.


Kind regards,

Rob
