README-SLACKWARE Written by Robby Workman You'll need to start the apcupsd service at boot. The recommended way is to add the following to your /etc/rc.d/rc.local script: if [ -x /etc/rc.d/rc.apcupsd ]; then /etc/rc.d/rc.apcupsd start fi Make sure the rc.apcupsd script is executable. Finally, you'll need to edit your /etc/rc.d/rc.6 script for apcupsd to perform the shutdown on power failures. Here's the short version: Scroll down to the end of rc.6 - you should see a section that calls /sbin/genpowerd. Comment out (or remove) this entire section: if [ -x /sbin/genpowerd ]; then # See if this is a powerfail situation: if /bin/egrep -q "FAIL|SCRAM" /etc/upsstatus 2> /dev/null ; then # Signal UPS to shut off the inverter: /sbin/genpowerd -k if [ ! $? = 0 ]; then echo echo "There was an error signaling the UPS." echo "Perhaps you need to edit /etc/genpowerd.conf to configure" echo "the serial line and UPS type." # Wasting 15 seconds of precious power: /bin/sleep 15 fi fi fi Now replace that section with this (or add immediately after it if you chose to comment out the original): # This will cause the UPS to kill the power supply after a configurable number # of seconds (see the apcupsd.conf file). This is important for situations # where the mains power comes back before the UPS batteries are completely # dead. if [ -f /etc/apcupsd/powerfail ]; then echo echo "apcupsd will now power off the UPS" echo /etc/apcupsd/apccontrol killpower echo echo "Please ensure that the UPS has powered off before rebooting." echo "Otherwise, the UPS may cut the power during the reboot." echo halt -f -p # power down the system if the hardware is capable fi
