Hi Simon - I modified /usr/lib/tmpfiles.d/nut-client to use /run instead of /var/run. I checked the startup status of the nut services. ================[root at mythtv ~]# systemctl list-unit-files | grep -i nut nut-driver-enumerator.path enabled disabled nut-driver-enumerator.service enabled disabled nut-driver at .service indirect disabled nut-monitor.service disabled disabled nut-server.service enabled disabled nut-driver.target disabled disabled nut.target disabled disabled ========================= I did a shutdown/reboot on the system. The usbhid driver loaded without errors and did not complain about /var/run. /run/nut exists and contains the expected two files. nut-server also started since it is set to "enabled", but failed to connect to the driver. It complains about "no such file or directory". What file is it looking for? I ran journalctl on it but got nothing more than what systemctl status reports. ==========================[root at mythtv ~]# systemctl status nut-driver at cyberpower ? nut-driver at cyberpower.service - Network UPS Tools - device driver for NUT device 'cyberpower' Loaded: loaded (/usr/lib/systemd/system/nut-driver at .service; enabled; preset: disabled) Drop-In: /etc/systemd/system/nut-driver at .service.d ??environ.conf /etc/systemd/system/nut-driver at cyberpower.service.d ??nut-driver-enumerator-generated-checksum.conf, nut-driver-enumerator-generated.conf Active: active (running) since Thu 2022-12-01 05:56:04 CST; 9min ago Process: 712 ExecStartPre=/usr/bin/systemd-tmpfiles --create /usr/lib/tmpfiles.d/nut-client.conf (code=exited, stat> Process: 719 ExecStart=/bin/sh -c NUTDEV="`/usr/libexec/nut-driver-enumerator.sh --get-device-for-service cyberpowe> Main PID: 791 (usbhid-ups) Tasks: 1 (limit: 9482) Memory: 2.9M CPU: 113ms CGroup: /system.slice/system-nut\x2ddriver.slice/nut-driver at cyberpower.service ??791 /usr/sbin/usbhid-ups -a cyberpower Dec 01 05:56:04 mythtv.billgee.local nut-driver at cyberpower[787]: Using subdriver: CyberPower HID 0.6 Dec 01 05:56:04 mythtv.billgee.local nut-driver at cyberpower[787]: Network UPS Tools - Generic HID driver 0.47 (2.8.0) Dec 01 05:56:04 mythtv.billgee.local nut-driver at cyberpower[787]: USB communication driver (libusb 1.0) 0.43 Dec 01 05:56:04 mythtv.billgee.local nut-driver at cyberpower[787]: cps_adjust_battery_scale: battery readings will be sca> Dec 01 05:56:04 mythtv.billgee.local nut-driver at cyberpower[719]: Network UPS Tools - UPS driver controller 2.8.0 Dec 01 05:56:04 mythtv.billgee.local usbhid-ups[791]: Startup successful [root at mythtv ~]# systemctl status nut-server ? nut-server.service - Network UPS Tools - power devices information server Loaded: loaded (/usr/lib/systemd/system/nut-server.service; enabled; preset: disabled) Active: active (running) since Thu 2022-12-01 05:56:07 CST; 9min ago Main PID: 809 (upsd) Tasks: 1 (limit: 9482) Memory: 1000.0K CPU: 15ms CGroup: /system.slice/nut-server.service ??809 /usr/sbin/upsd -F Dec 01 05:56:08 mythtv.billgee.local upsd[809]: listening on ::1 port 3493 Dec 01 05:56:08 mythtv.billgee.local upsd[809]: listening on 127.0.0.1 port 3493 Dec 01 05:56:08 mythtv.billgee.local nut-server[809]: /var/run is world readable Dec 01 05:56:08 mythtv.billgee.local nut-server[809]: Can't connect to UPS [cyberpower] (usbhid-ups-cyberpower): No suc> Dec 01 05:56:08 mythtv.billgee.local upsd[809]: /var/run is world readable Dec 01 05:56:08 mythtv.billgee.local upsd[809]: Can't connect to UPS [cyberpower] (usbhid-ups-cyberpower): No such file> Dec 01 05:56:10 mythtv.billgee.local nut-server[809]: Running as foreground process, not saving a PID file Dec 01 05:56:10 mythtv.billgee.local upsd[809]: Running as foreground process, not saving a PID file Dec 01 06:01:08 mythtv.billgee.local nut-server[809]: Can't connect to UPS [cyberpower] (usbhid-ups-cyberpower): No suc> Dec 01 06:01:08 mythtv.billgee.local upsd[809]: Can't connect to UPS [cyberpower] (usbhid-ups-cyberpower): No such file> =============================== ==============Bill Gee On 11/30/22 21:14, Simon Wilson via Nut-upsuser wrote:> ----- Message from Bill Gee <bgee at campercaver.net> --------- > ??

[Nut-upsuser] NUT no longer works after 2.7 -> 2.8 upgrade
The `nut-server` (upsd) should be looking for pipe-files from drivers in the "STATEPATH" (should be `/run/nut` in your case as the driver got set up like this now). The `/var/run is world readable` complaint indicates the `upsd` looks in `/var/run`rather than `(/var)/run/nut`. While debugging startups, it may help to set non-zero `debug_min` so the daemons (data server, drivers, upsmon) would be more verbose in their systemd journals: * https://github.com/networkupstools/nut/blob/035ae79dc28a04c443f110bd7046aab3c504319b/conf/upsd.conf.sample#L152 * https://github.com/networkupstools/nut/blob/035ae79dc28a04c443f110bd7046aab3c504319b/conf/upsmon.conf.sample.in#L447 * https://github.com/networkupstools/nut/blob/035ae79dc28a04c443f110bd7046aab3c504319b/docs/man/ups.conf.txt#L143 * https://github.com/networkupstools/nut/blob/035ae79dc28a04c443f110bd7046aab3c504319b/docs/man/ups.conf.txt#L281 Hope this helps, Jim Klimov On Thu, Dec 1, 2022 at 1:14 PM Bill Gee <bgee at campercaver.net> wrote:> Hi Simon - > > I modified /usr/lib/tmpfiles.d/nut-client to use /run instead of > /var/run.

[Nut-upsuser] NUT no longer works after 2.7 -> 2.8 upgrade
Hi Bill, well at least you now have a fully operating, starts-on-reboot driver - so that is progress. One thing we need to know which I asked but you've not answered: "Did you need to add the environment drop-in file? At which step did it work?" The answer to that may change next step. nut-server *should* just work if there is a driver available and running. OK, run: systemctl disable nut-server (stop it trying to run automatically) upsd -DD And then Ctrl-C to stop it once you have got output to screen with startup messages. Then copy back here the output from upsd -DD, preferably without truncating lines which your mail client seems to do :( I'm pretty sure that nut-server is using /var/run as its STATEPATH. Can you also include your upsd.conf, minus commented lines.
