[Nut-upsuser] ubuntu 8.04 upssched CANCEL-TIMER ignored

[Herwarth Heitmann]

hello,

every two weeks my system shutsdown because my apc ups does a self  
test and nut is not picking up the cancel timer event.

according to me all settings are correct. in my upssched-cmd script i  
execute a remote shutdown, because nut is running in a virtual machine  
and i want the script to shutdown all hosts in my esx environment.

my upssched-cmd script
----
#!/bin/sh

	$LOGGER -t upssched-cmd "The UPS has been on battery for awhile"
  	echo "The UPS has been on battery for a while, logout right now!" |  
$WALL
         ;;
