| As always... | |
|---|---|
|
Start with: |
|
Install NUT
sudo apt install nut
Configure NUT
Select your mode
sudo vi /etc/nut/nut.conf
MODE=netserver
(In my case, I've installed NUT on a VM and it'll be managing the UPS for the whole server...)
| none |
Disable automatic startup of NUT |
| standalone | This MODE is for local only configuration |
| netserver | This MODE is open to the network. (A NUT server) |
| netclient | This MODE is for client machines that will access a NUT server |
See the nut.conf documentation for more details.
Select your hardware
sudo vi /etc/nut/ups.conf
[cyberpower]
driver = usbhid-ups
port = auto
desc = "A random surplus UPS"
(In my case, I'm setting up a CyberPower 1000AVR & connecting it by passing USB through to the VM...)
If your UPS isn't handled natively by the usbhid-ups driver, or you need to set options, start with the ups.conf documentation for more details.
Start & test
sudo upsdrvctl start
You should see:
Network UPS Tools - UPS driver controller 2.7.4 Network UPS Tools - Generic HID driver 0.41 (2.7.4) USB communication driver 0.33
Possibly followed by a bit of information about your UPS
Set up communications
(needed if you've set up as MODE = netserver...)
You can determine your servers IP address using:
ip asudo vi /etc/nut/upsd.conf
LISTEN 192.168.2.219 LISTEN 127.0.0.1 3493 LISTEN ::1 3493
Where 192.168.2.219 should be replaced with the actual IP of the machine.
See the upsd.conf documentation for more details.
Set up access
sudo vi /etc/nut/upsd.users
[upsmon]
password = supersecretpassword
upsmon master
See the upsd.users documentation for more details.
sudo vi /etc/nut/upsmon.conf
MONITOR cyberpower@192.168.2.219 1 monuser supersecretpassword master
See the upsmon.conf documentation for more details.
