[Nut-upsuser] [nut-upsusers] NUT 2.8.0r3 | NUT-clients are loosing connection to UPS over SNMP-driver
Hello Becoming somewhat "desperate" I configured and tested (for hours) to get a NUT-Server/Client 2.8.0r3 installation to work together with a CyberPower OLS1500 UPS over SNMP v3. As NUT-packages for ubuntu are still at version 2.7.4 and this NUT-SNMP-driver does not report very much information from the CyberPower UPS, I decided to compile/install from source the 2.8.0r3 version with the following configure settings: ./configure --with-snmp --with-cgi --with-scanner -with-docs --with-user=root --with-group=nut --sysconfdir=/etc/nut/ now with version 2.8.0r3 I get over upsc full information from my ups (named ups00) over SNMP. Also NUT-cgi reports full information and is refreshed accordingly. /usr/local/ups/bin/upsc ups00 battery.charge: 100 battery.current: 1 battery.runtime: 2880 battery.runtime.elapsed: 0 battery.voltage: 54.60 battery.voltage.nominal: 48 device.contact: Administrator device.description: UPS SNMP Card device.location: Server Room device.mfr: CYBERPOWER device.model: OLS1500ERT2UA device.serial: 3003070Z30000042 device.type: ups driver.name: snmp-ups driver.parameter.pollinterval: 1 driver.parameter.port: 192.168.1.10 driver.parameter.secLevel: authPriv driver.parameter.snmp_version: v3 driver.parameter.synchronous: auto driver.version: 2.8.0-rc3 driver.version.data: cyberpower MIB 0.51 driver.version.internal: 1.21 input.frequency: 49.90 input.voltage: 232.50 output.current: 1 output.frequency: 49.90 output.voltage: 232.50 ups.delay.reboot: 0 ups.delay.shutdown: 180 ups.delay.start: 0 ups.firmware: OS02RV07 ups.load: 17 ups.mfr: CYBERPOWER ups.model: OLS1500ERT2UA ups.serial: 3003070Z30000042 ups.status: Also the NUT-Server (v2.8.0r3) seems to works correct and 3 NUT-clients (1 local, 2 remote) can login correctly to the NUT-Server and to the ups00. nut-server[1069]: User upsmon at 127.0.0.1 logged into UPS [ups00] upsd[1069]: User upsmon at 127.0.0.1 logged into UPS [ups00] nut-server[1069]: User upsmon at 192.168.1.211 logged into UPS [ups00] upsd[1069]: User upsmon at 192.168.1.211 logged into UPS [ups00] nut-server[1069]: User upsmon at 192.168.1.11 logged into UPS [ups00] upsd[1069]: User upsmon at 192.168.1.11 logged into UPS [ups00] Unfortunately all NUT-clients (also the local NUT-client) are reporting directly after the first refresh and then continuously, that they have lost connenctions to the ups00 but they are still loggedin to the NUT-Server. ... nut-monitor[1078]: UPS ups00 at localhost is unavailable nut-monitor[29503]: Network UPS Tools upsmon 2.8.0-rc3 ... So my question is, what could be "wrong" in configuration and/or installation, that all clients (local or remote) are reporting that they have lost connection to the ups00 and that it is not unavailable? Many thanks in advance for any hint, best

On the road now so gotta come back to main question later, but for now - why 2.8.0-rc3 (not "r3")? There is a newer final release, or current master... just asking. Notably, there was a fix in master last week or so that moght help woth some broken large queries for SNMPv2/v3... No idea if that's your case though. Error messages from clients might help.
