Installing NUT (Network UPS Tools) on Ubuntu 18.04 LTS

Original How-To URL: https://zackreed.me/installing-nut-on-ubuntu/ 

 Install Nut 

 apt-get install nut 

 Edit /etc/nut/ups.conf 

 vi /etc/nut/ups.conf 

 Paste the foollowing at the bottom. Mine’s an APC-1500, so I’ve set it to a recognizable name (apc-1500) 

 [apc-1500]

driver = usbhid-ups

port = auto 

 Create the following directories and reboot machine 

 mkdir /var/run/nut 

 chown root:nut /var/run/nut 

 chmod 770 /var/run/nut 

 Start NUT 

 upsdrvctl start 

 Should give the following output 

 Network UPS Tools - UPS driver controller 2.4.3

Network UPS Tools - Generic HID driver 0.34 (2.4.3)

USB communication driver 0.31

Using subdriver: APC HID 0.95

 

 Setup NUT to listen on Port 3493 

 vi /etc/nut/upsd.conf 

 Add the following lines where <IPADDRESS> is the IP of your machine 

 LISTEN 127.0.0.1 3493

LISTEN ::1 3493

LISTEN <IPADDRESS> 3493 

 Set the mode 

 Edit /etc/nut/nut.conf: 

 vi /etc/nut/nut.conf 

 Enter the following: 

 MODE=netserver 

 Start the network data server 

 upsd 

 Check the status 

 upsc apc-1500@localhost ups.status 

 Should output the following 

 OL 

 OL means your system is running On Line power. If you want to see all the info, try this instead 

 upsc apc-1500@localhost 

 Should output the following 

 ...

battery.charge: 100

battery.charge.low: 10

battery.charge.warning: 50

battery.date: 2054/00/39

battery.mfr.date: 2008/10/20

--- 

 Disable the beeper if needed 

 upscmd apc beeper.disable 

 Setup users to access the info and make changes. 

 vi /etc/nut/upsd.users 

 Add monitor master user and a monitor slave user for remote machines 

 [monuser]

 password = PASSWORD_REPLACE

 actions = SET FSD

 instcmds = ALL

 upsmon master

 # or upsmon slave

[monuserslave]

 password = slave

 upsmon slave 

 Reload upsd 

 upsd -c reload 

 Setup upsmon for our machine 

 vi /etc/nut/upsmon.conf 

 Paste the following 

 MONITOR apc-1500@localhost 1 local_mon PASSWORD_REPLACE master 

 Setup Nut in standalone mode 

 vi /etc/nut/nut.conf 

 Paste the following 

 MODE=standalone 

 Start NUT 

 service nut start 

 Setting up a Client (Slave) Computer 

 Install NUT 

 apt-get install nut 

 Edit /etc/nut/nut.conf 

 vi /etc/nut/nut.conf 

 Paste the following 

 MODE=netclient 

 Set your upsmon.conf to match the setup for your monuserslave above and the ip address of your master nut-server 

 vi /etc/nut/upsmon.conf 

 Paste the following where <IPADDRESS> is the ip of your NUT Server and <PASSWORD> is the password of your monuserslave password from above 

 MONITOR apc-1500@<IPADDRESS> 1 monuserslave <PASSWORD> slave 

 Restart your nut-client 

 service nut-client restart 

 Test with the following command where <IPADDRESS> is the IP of your NUT server 

 upsc apc-1500@<IPADDRESS> 

 Should output the following
