# c4lab-server Share UPS status across machines
###### tags: `c4lab`

## TL;DR

## Backgroud
I have four machines plugged on apcups, include two server, one Synology NAS, one QNAP NAS. Yet the ups has only one USB port, I will try to share the ups status to all machines and notify them whether the power is gone.

## Get UPS status via USB
Connect one of the server to APC via USB.

Then, setup apcupsd

For Ubuntu

sudo apt -y install apcupsd

In `/etc/apcupsd/apcupsd.conf`

UPSCABLE usb
UPSTYPE usb
NETSERVER on
NISIP 0.0.0.0
NISPORT 3551

The NISIP is set to `0.0.0.0` that allow remote access.

And start the services

sudo systemctl enable apcupsd
sudo systemctl start apcupsd

## Connect by other server
The other server can get the ups status by apcupsd through network

In `/etc/apcupsd/apcupsd.conf`

UPSCABLE ether
UPSTYPE net
DEVICE 192.168.1.2:3551

where `192.168.1.2` is the IP of server connected via USB.

Don't forget to manage by systemctl.

## Before Connect to NAS
Both Synology and QNAP are support `nut` protocal.

Now we setup nut server:

You can install nut server or start it in Docker
* Ubuntu: `sudo apt install -y nut`
* Docker: kmlucy/docker-nut

The Configuration:
`nut.conf`

MODE=netserver

`upsd.conf`

LISTEN 0.0.0.0 3493

`upsd.user` and `ups.conf` are also need to modify. I will mention later.

## Connect to synology NAS
You can login to Synology NAS terminal to find the setting of nut client. It is in `/usr/syno/etc/ups`, however, it doesn't work when I change the default setting. Thus I try to fit it by changing our configuration.

`upsd.user`

[monuser]
	password = secret
	actions = SET
	instcmds = ALL
	upsmon slave

`ups.conf`

[ups]
	driver = apcupsd-ups
	port = 192.168.1.2:3551
	desc = "My ups"

And in Synology NAS: Change the setting in the web interface.
It works if the `Device Information` can show the status.

## Connect to QNAP NAS
The setting are located in `/etc/config/ups` in QNAP terminal. It doesn't work again when I change the default setting. Here is my setting for QNAP.

`upsd.user`

[admin]
	password = 123456
	actions = SET
	instcmds = ALL
	upsmon slave

`ups.conf`

[qnapups]
	driver = apcupsd-ups
	port = 192.168.1.2:3551
	desc = "c4lab ups for qnap"

Setup in QNAP web

## Merge them
Now, you can merge the configuration together if you have both Synology and QNAP NAS.

`upsd.user`

[monuser]
	password = secret
	actions = SET
	instcmds = ALL
	upsmon slave
    
[admin]
	password = 123456
	actions = SET
	instcmds = ALL
	upsmon slave

`ups.conf`

[ups]
	driver = apcupsd-ups
	port = 192.168.1.2:3551
	desc = "My ups"
    
[qnapups]
	driver = apcupsd-ups
	port = 192.168.1.2:3551
	desc = "c4lab ups for qnap"
