nut version: 2.8.1-3 Hello Laurent,
it took me a while to set up another computer now with a Debian kernel. I can affirm that nut in my configuration is working as expected. After connecting the UPS via USB cable I had to restart the nut-server: # service nut-server restart resulting in the output > Restarting NUT - power devices information server and drivers: upsd (driver(s) failed) driver(s). upsd. Then I switched off IPv6 again by adding 'ipv6.disable=1' to the variable 'GRUB_CMDLINE_LINUX' in '/etc/default/grub', commanding update-grub as root and restarting the computer. Now the daemon 'upsd' fails to start: # service nut-server restart Restarting NUT - power devices information server and drivers:No upsd found running; none killed. upsd driver(s) (driver(s) failed). (upsd failed). Therefore, I think the severity could be changed to 'minor'. Do you think it might be possible to make nut working without IPv6? Regards, Jörg.
