In this tutorial you will learn how to install and manage the apcupsd daemon to control your computer in the event of a power outage. This assumes that you have a recent APC Uninterruptable Power Supply (UPS) for your system. My experience here is with the APC Back-UPS RS 1500 but should serve as a guide for other APC set-ups as well.
If you have a Belkin UPS this link may be of some help.
Also, I have created an addendum to this tutorial if you are using an older APC UPS with a 'dumb' connection (ADDED: 2004-03-14).
There is also a brief HOWTO on using NUT to monitor your UPS here.
NOTE for Fedora Core 2 & 3: I have not tried this, but have been told it works. You will need to create the USB devices since the 2.6 kernel doesn't see them automatically. To do this run, as root:
% /etc/apcupsd/make-hiddev % cp -rp /dev/usb /etc/udev/devicesSee: fedoraforum.org/forum/showthread.php?t=29168 for more information on using with FC 2&3.
Getting Started (Installation):
Be sure that the dag repositories are in your apt-get list.
See the apt howto for more information.
Once the dag repositories are seen by apt just
run the following:
% apt-get install apcupsd Reading Package Lists... Done Building Dependency Tree...

After unpacking 5129kB of additional disk space will be used. Get:1 http://apt.sw.be redhat/fc1/en/i386/dag apcupsd 3.10.11-1.rhfc1.dag [2797kB] Fetched 2797kB in 23s (117kB/s) Committing changes...

If you are not using apt, then just download the latest fc1 package from http://dag.wieers.com/packages/apcupsd/ (here I use
apcupsd-3.10.11-1.rhfc1.dag.i386.rpm).
Alternatively, you can download the appropriate rpm from the
official sourceforge repository, choosing between the USB and STD rpms for FC1.
Then run:
% rpm -ivh apcupsd-3.10.11-1.rhfc1.dag.i386.rpm Preparing... ########################################### [100%] 1:apcupsd ########################################### [100%]
apcupsd should now be successfully installed on your fedora box. A simple check, that will also let you know which run-levels it is on is to type the following ls command:
% ls /etc/r*/*apcupsd /etc/rc0.d/K99apcupsd /etc/rc3.d/S20apcupsd /etc/rc6.d/K99apcupsd /etc/rc1.d/K99apcupsd /etc/rc4.d/S20apcupsd /etc/rc2.d/S20apcupsd /etc/rc5.d/S20apcupsd
This shows that it is set to startup in runlevels 2-5 and shutdown in 0, 1 and 6. This is correct.
