It might be possible with upsrw - try

I'm looking into some network "weirdness", and I noticed that a CentOS 6 system with multiple IP addresses (load balancer running keepalived) is sending ARP requests from apparently random source IPs. I would have thought that ARP requests would always come from the interface's "primary" IP (especially since keepalived adds all the virtual IPs with a /32 mask). This

Hello, We have an Eaton 3S 550 UPS using NUT tool to send power loss event. By default the power voltage threshold is set to 85 volts. If the voltage is less than 85 volts, it will trigger ONBATT event from NUT. Is there a way in NUT we can change the threshold from 85 volts to a lower voltage like 40 volts? We were trying to change ups.conf to modify the output of upsc ..., but looks like it

Hello Charles, Thank you so much for your reply. Yes. 40v was too low. In windows, those range started from 76v, 85v, and 96v. Just tried upsrw command to modify input.transfer.low and input.transfer.boost.low. There were some error messages returned. Tried another one battery.charge.low and it returns ok. $ sudo upsrw -s input.transfer.low=70 -u * -p * ups Unexpected response from upsd: ERR READONLY $ su...
