Linux

• Why don't the pathnames in your documentation match the package I installed?
  • chop off the /usr/local/ups part & all is good. (at least here...)
• Why do the client programs say Driver not connected when I try to run them?
  • oops... sudo upsdrvctl start hasn't happened...
• What's this about data stale?
  • Brute force solutions:
    • Unplug & replug the USB cable...
    • or restart the driver...
      • sudo upsdrvctl stop
      • sudo upsdrvctl start
      • (dunno why there's no "restart" option...)
  • hhhmmm... Wonder if /etc/init.d/nut-server force-reload would fix it...
    • yup...
