Hi,

I have a APC back-UPS connected to Network device and would like to connect from Centos 6.9 to this device.
I managed to install the application but I don’t know how to configure the apcupsd.conf correctly to connect via the network to the network device which is connected to the UPS.


My OS: CentOS release 6.9 (Final)

Version apcupsd: 3.14.14

The model and UPS cable you are using: back-ups es 700 APC, NO UPS cable, connection via network.

I try to configure it but I am getting this error:

service apcupsd start
Starting UPS monitoring:apcupsd FATAL ERROR in apcconfig.c at line 672
Terminating due to configuration file errors.


Kind Regards,

Rob

Is there any reason for not reading APCUPSD's manual (which is excellent IMHO)? It explains all details, including running multiple APCUPSD instances where only one of them actually has access to a UPS, and shows sample configurations.

You said this was a backup es connected to the computer with a cable, so
the net driver would definitely be the wrong driver to use.

Please confirm the UPS model number, and describe exactly the cable
you are using, and any numbers on the cable ends (they will be black
raised letters on a black cable so they won't stand out you will have
to look for them) and describe the port on the PC that you are plugging
the cable into.

Hi,


I have a APC back-UPS connected to Network device (Synology NAS) and would like to connect from Centos 6.9 to this device (Synology NAS).
I managed to install the application but I don’t know how to configure the apcupsd.conf correctly to connect via the network to the network device (Synology NAS) which is connected to the UPS.


My OS: CentOS release 6.9 (Final)

Version apcupsd: 3.14.14

The model and UPS cable are : back-ups es 700 APC

I am trying to connect over the network.

When I look at another connection. Synology to Synology I see this.

tcp 0 0 <ip address, Synology with UPS>:3493 <ip address, Synology without UPS, over the network:60126 ESTABLISHED 4707/upsd

So the port must be 3493




Kind Regards,

Rob

Please re-read the instructions Ted gave in the second paragraph of his post, and follow them step by step. Tell us exactly what cable you are using to connect the UPS to your NAS, in particular if this is the genuine APC cable that came with the UPS, and if yes, tell us the numbers which are imprinted onto the connectors at both ends of the cable. After having done so, consider the following recommendation:

Generally, you are putting the cart before the horse. The first step is to make the UPS work correctly *on the device it is attached to*. Login to your NAS (preferably using SSH and getting a command line, or by connecting a keyboard and a monitor to your NAS (if possible) and getting a command line) and check if apcupsd *ON THE NAS* correctly recognizes the UPS. The easiest way to do so would be either studying the log files or using the apcaccess and apctest tools (they are both part of apcupsd - no need to install them separately). Please read apcupsd's manuals to learn how to use these tools.

On the Synology NAS: USB port: 940-0127E


UPS, dataport: AWM E101344 style 2725 VW-1 60 C 30V SPACE . SHUTTLE

The dataport is like a RJ-45 connector.

The Synology NAS with the UPS connected has a graphical interface where you can configure some settings. Another Synology NAS is successfully connected to the Synology NAS.
I checked the Synology NAS and I cannot discover the apcupsd running.

The mentioned tools apcaccess and apctest I cannot find either.

I found a program: apcsmart

Network UPS Tools - APC Smart protocol driver 3.1

I installed APCUPSD on the centos 6.9 OS. Not on the Synology NAS which has the APC UPS connected.
So, if you can't install apcupsd on the device where the UPS is attached
to, then you can't monitor the UPS via network. Pretty clear, isn't it?
Synology says it is not supported, apcupsd. I don’t know yet if it can be done unsupported. I am trying to find out which implementation is done on the Synology NAS.

Rob
Unfortunately, there is no announced plan to support this feature at the
moment. I apologize for your inconvenience. However, I have passed this
message to our developers and product management group. They will have
more research on such feature. Thank you for bringing this issue to our
attention.
If I want this to work I suppose APCUPSD has to be installed on the
Synology NAS. But no support from Synology.
Please forgive me, but it seems I don't get it.
In your first post, you have written: "I managed to install the
application ...". How did you mean this?
Of course, you have to install (and correctly configure) apcupsd on the
device *where the UPS is attached to* before another instance of apcupsd
(on another device) can connect to the apcupsd instance on the first device.
So, if you can't install apcupsd on the device where the UPS is attached
to, then you can't monitor the UPS via network. Pretty clear, isn't it?

Binarus

So it should be obvious, you need to connect the APC UPS to the system with Centos 6.9 OS installed. Other systems in your network (but probably not the Synology NAS) can then network connect to the Centos system.

Centos system.
You are right provided that he has his CentOS system besides his
Synology NAS. But chances are that the NAS is in a separate room, i.e.
the NAS is "far" away from his CentOS system. Since he obviously wants
to protect his NAS against power failures, connecting the CentOS system
to the UPS would be complicated then:

- He could place the UPS besides his NAS and connect the NAS power input
to the UPS's power outlet. Then he could connect the UPS's data port to
his CentOS system. This would probably mean making his own data cable
because the genuine data cable probably is not long enough.

- He could place the UPS besides his CentOS system and connect the UPS's
data port to the CentOS system using the genuine cable. But then he
would have to lay a power cable from the UPS's power outlet to his NAS's
power input, possibly over a long distance.

Both variants might not be possible at all because he eventually can't
lay cables over long distances in his apartment / house.

Furthermore, to have the NAS actually shut down in case of power
failures, he would need some tricky scripts (for example, he could have
apcupsd on his CentOS box run a script in case of a power failure, where
the script logs into his NAS via SSH and then issues a shutdown command
there - I have done such things in similar situations).

Finally, there might be problems due to grounding if the data port of
the UPS is connected to a device whose power input is not connected to
the UPS's power outlet as well. Thus, to be on the safe side, he would
have to connect both devices' power inputs to the UPS power outlet in
every case.

Usually, the NAS OS is some Linux variant, possibly modified by the
vendor. Chances are that there is a compiler on your NAS, so you
eventually can log in (via SSH), load apcupsd's source code onto the NAS
and compile it yourself.

If this is not possible, I would advise you to use another "open"
firmware for your NAS, like Pavel already has suggested.

I didn’t have a reply yet from the Vendor.


The machine running CentOS, the UPS and the Synology NAS are very close together. The are also on the same subnet.

Yes, the Synology NAS I want to protect against power failure with the highest priority. But preferable also other devices. For example the device running CentOS.

The Synology NAS has an USB port in front which is used for connection with the dataport on the APC UPS.
The NAS power input is connected to the UPS’s power outlet.
The CentOS device power input is connected to the UPS’s power outlet.

The CentOS device has also USB interfaces. So it is possible to connect the CentOS device via USB with the dataport on the APC UPS. But then the Synology NAS is not connected via the dataport. It is still connected via the NAS power input to the UPS’s power outlet.

Via a script running on the Synology ( via SSH) to shutdown the CentOS machine would possible be an option. I have to find out what will trigger the script from running and shutdown the CentOS device.
Or when the CentOS device is connected with the UPS via the dataport to shutdown the Synology NAS.

I have got a reply back from Synology:

Yes, we implement by NUT version 2.7.2.

So they have implemented NUT. I suppose I have to try first to connect via a NUT client to the Synology NAS which is running NUT and attached to the UPS.

Ppl usually deal with this by replacing proprietary Linux distribution by
some open-source like OpenNAS, FreeNAS etc. I however suggest studying those
first, some of them do not support apcupsd either (or it is very
problematic) in favor of NUT (which has great support for Eaton, or vice
versa, from Eaton, but generaly very bad for APC products).

This is an important information which we will need later.

This is the reason why I recommended using the command line. I know exactly
nothing about Synology NASes, so I can't help out until you are ready to
investigate things using the command line. I never have heard of the tool
"apcsmart". On the other hand, apcaccess and apctest are standard tools for
investigating problems or getting the status from apcupsd, and since they
are part of apcupsd, I am quite sure that they are on your NAS. But they are
command line tools, so you probably can't operate them using the graphical
interface.

Please let us know when you have managed to get a command line via SSH on
your NAS where the UPS is attached to. Then we can discuss the further
steps. Google for "Synology SSH" if you are new to this.

In the meantime, please show us the apcupsd.conf which you have on the NAS
where the UPS is attached to (I suppose the apcupsd.conf you already have
posted is the one from your other NAS).

Regards,

Binarus

Synology says it is not supported, apcupsd. I don’t know yet if it
can be done unsupported. I am trying to find out which implementation
is done on the Synology NAS.
I found a program: apcsmartÂ
Network UPS Tools - APC Smart protocol driver 3.1
http://networkupstools.org/

Looks like apcupsd may be available as a package on Synology devices...

|from https://www.google.com/search?q=apcupsd+synology+nas|

|"ipkg install apcupsd"


Hope that helps.
