Hi all, I?ve searched online for a solution to my issue with no luck...hoping someone here can help. Connected a Cyberpower SX950U UPS to my Synology NAS. Configured UPS on Synology NAS: [cid:image002.png at 01D89A1B.B3AAA850] Installed and configured NUT on Ubuntu 18.04.5 Server: 1. Installed NUT: sudo apt-get install nut 2. Modified /etc/nut/nut.conf with mode=netclient 3. Added MONITOR ups at 192.168.0.102 1 USER PASS slave to /etc/nut/upsmon.conf Receiving the following errors: user at ubuntu:~$ sudo systemctl status nut-client.service ? nut-monitor.service - Network UPS Tools - power device monitor and shutdown controller Loaded: loaded (/lib/systemd/system/nut-monitor.service; enabled; vendor preset: enabled) Active: active (running) since Sun 2022-07-17 19:00:19 EDT; 2min 8s ago Process: 25805 ExecStart=/sbin/upsmon (code=exited, status=0/SUCCESS) Main PID: 25839 (upsmon) Tasks: 2 (limit: 4915) CGroup: /system.slice/nut-monitor.service ??25835 /lib/nut/upsmon ??25839 /lib/nut/upsmon Jul 17 19:00:18 ubuntu upsmon[25835]: Startup successful Jul 17 19:00:18 ubuntu systemd[1]: Stopped Network UPS Tools - power device monitor and shutdown controller.

Jul 17 19:00:19 ubuntu upsmon[25839]: Login on UPS [ups at 192.168.0.200] failed - got [ERR ACCESS-DENIED] Jul 17 19:00:18 ubuntu systemd[1]: nut-monitor.service: Can't open PID file /var/run/nut/upsmon.pid (yet?) after start: No such file or directory Jul 17 19:00:18 ubuntu systemd[1]: nut-monitor.service: Supervising process 25839 which is not our child. We'll most likely not notice when it exits. Jul 17 19:00:19 ubuntu systemd[1]: Started Network UPS Tools - power device monitor and shutdown controller. Are USER and PASS what I use to log into my Synology NAS? The fie /var/run/nut/upsmon.pid only contains a single line. Is this correct? Why does the monitor service report No such file or directory? user at ubuntu:~$ cat /var/run/nut/upsmon.pid 25839 Sincerely appreciate anyone?s input.
