apcupsd(8)                  System Manager's Manual                 apcupsd(8)



NAME
       apcupsd - daemon for most APC's UPS for Linux

SYNOPSIS
       /sbin/apcupsd
       /etc/apcupsd/apccontrol
       /etc/apcupsd/apcupsd.conf
       /sbin/apcaccess
       /sbin/apcnetd

DESCRIPTION
       This  document  is considerably out of date. It can be used for a brief
       overview of apcupsd, but you should consult the html manual for current
       information.  Normally this manual will be loaded on your system in the
       doc directory, which varies from system to system. Otherwise,  you  may
       find an online version at: http://www.apcupsd.com


       This  daemon  can be used for controlling the most APC UPSes.  During a
       power failure, "apcupsd" will inform the users about the power  failure
       and  that  a  shutdown  may  occur.  If power is not restored, a system
       shutdown will follow when the battery is exausted, a timeout  (seconds)
       expires,  or  runtime expires based on internal UPS calculations deter-
       mined by power consumption rates.  If the power is restored before  one
       of  the  above  shutdown  conditions  is met, apcupsd will inform users
       about this fact.

       The shutdown is made  by  script  calls  to  "/etc/apcupsd/apccontrol",
       which is called by "apcupsd".  Consequently, no changes to /etc/inittab
       are necessary.  There is no communication between apcupsd  and  init(1)
       process.   Apcupsd  modifies  the halt script so that at the end of the
       shutdown process, apcupsd will be re-executed in order to power off the
       UPS.  On  certain  platforms  (e.g. FreeBSD) there is no halt script so
       apccontrol must be modified to cause apcupsd to power off the UPS after
       a delay time.


       The  apcupsd  daemon  now  supports  two networking modes that function
       independently, but if desired they can both run at the same time.

       Most users will probably enable the first  network  mode  (NIS),  which
       permits  apcupsd  to serve status and event information to clients over
       the network.

       The second networking mode is for multiple networked machines that  are
       powered  by  the same UPS. In this mode, one machine is configured as a
       master with the UPS attached to the serial port.   The  other  machines
       (max.   20) powered by the same UPS are configured as slaves.  The mas-
       ter has a network connection with the slaves and sends them information
       about the UPS status.


       RedHat  and  SuSE  versions  of Linux have direct install support.  All
       other flavors of Linux may need some fussing with to  get  the  install
       correct.

OPTIONS
       -c --configure
              Attempts  to  configure the UPS EPROM to the values specified in
              the configuration file "/etc/apcupsd/apcupsd.conf".  This option
              is  now  deprecated  (not  supported)  and  should  not be used.
              Instead use the apctest program, which has an interactive EEPROM
              configuration.

       -d --debug <&lt;level>&gt;
              Turns on debugging output.

       -f --config-file <&lt;file>&gt;
              Specifies  the  location of the configuration file.  The default
              is: /etc/apcupsd/apcupsd.conf

       -k --killpower
              Attempt to turn the UPS off. This option is normally  only  used
              by the daemon itself to shut the UPS off after a system shutdown
              has completed.

       -V --version
              Prints the apcupsd version number and the help.

       -? --help
              Prints a brief apcupsd help screen.


CONFIGURATION
       It may be necessary to change the configuration information in the file
       "/etc/apcupsd/apcupsd.conf"  to  meet  your  needs and to correspond to
       your configuration.  This file is a plain ASCII file and  you  can  use
       your favorite editor to change it.

       Configuration commands in /etc/apcupsd/apcupsd.conf are:


   GENERAL CONFIGURATION COMMANDS
       UPSCABLE -- <type of cable you are using>
       [ simple | 940-0020B | 940-0023A (broken) ]
       [ smart | 940-0024B | 940-0024C ]
       [ 940-0095A | 940-0095C ]
       [ ether ]
       [ usb ]

       UPSTYPE -- <Type of APCC UPS you have>
       [ dumb | apcsmart | net | usb | snmp | test ]

       DEVICE -- <name of serial port>
       Please specify which device is used for UPS communication.  The default
       is /dev/ttyS[0|1|2|3].  If you have a USB UPS, it is  /dev/usb/hid/hid-
       dev[0-9].    On   some  Red  Hat  versions  you  may  need  to  specify
       /dev/usb/hiddev[0-9]

       LOCKFILE -- <path to lockfile>
       By supplying this argument, "apcupsd" tries to create  a  lockfile  for
       the serial or USB port in the specified directory.




   CONFIGURATION COMMANDS USED BY THE NETWORK INFORMATION SERVER
       NETSTATUS [on | off]
       This  configuration  command turns the network information server on or
       off. If it is on, apcupsd will spawn a child process that serves STATUS
       and  EVENTS information over the network. This information is currently
       used by the Web based CGI programs.  The default is on. In some  cases,
       for  added  security,  you  may  want  to invoke a separate information
       server daemon from the inetd daemon. In this case, NETSTATUS should  be
       off.


       STATUSPORT <port>
       This configuration command specifies the port to be used by the apcupsd
       server. The default is 7000. If you change this port, you must manually
       change  the #define SERV_TCP_PORT in cgi/upsfetch.c and rebuild the CGI
       programs.


       EVENTFILE <filename>
       If you want the apcupsd network information server to provide the  last
       10  events  via the network, you must specify a file where apcupsd will
       save these events. The default is: /var/log/apcupsd.events.  Currently,
       apcupsd  will save at most the last 50 events. When more than 50 events
       are recorded and a network request for the events arrives, the  network
       server  will  truncate  the  file  to the most recent 10 events. Conse-
       quently this file will not grow indefinitely as long as the events  are
       checked from time to time.



   CONFIGURATION COMMANDS USED TO CONTROL SYSTEM LOGGING
       STATTIME


       STATFILE


       DATATIME


       FACILITY




       CONFIGUATION COMMANDS USED DURING POWER FAILURES

       ANNOY -- <time in seconds>
       Please  specify  the time in seconds between messages requesting logged
       in users to get off the system. This timer starts only when the UPS  is
       running on batteries.  The default is 300 seconds (5 minutes).

       ANNOYDELAY -- <time in seconds>
       Please  specify  delay time in seconds before apcupsd begins requesting
       logged in users to get off the system. This timer starts only after the
       UPS  is  running  on  batteries.   This  timer  is reset when the power
       returns. The default is 60 seconds.  That is the first warning  to  log
       off the system occurs after 60 seconds on batteries.



       NOLOGON -- <specifies when apcupsd should create the nologon file>
       [ disable | timeout | percent | minutes | always ] are valid types.

       Based  on Ten (10) percent of a setting.  This allows one to define the
       point when the /etc/nologin file  is  added.   This  is  important  for
       allowing  systems  with  BIG  UPSes to run as normally until the system
       administrator determines the need for dumping users.  The feature  also
       allows  the  system  administrator to hold the "ANNOY" factor until the
       /etc/nologin file is added.

       disable prevents apcupsd from creating the nologin file.

       timeout specifies a specific wait  time  before  creating  the  nologin
       file.

       percent  specifies the percent battery charge remaining before creating
       the nologin file.

       minutes specifies the battery runtime  remaining  before  creating  the
       nologin file.

       always  causes  the  nologin  file to be immediately created on a power
       failure.

       BATTERYLEVEL -- <percent of battery>
       If BATTERYLEVEL is specified, during  a  power  failure,  apcupsd  will
       shutdown  the  system when the remaining battery charge falls below the
       specified percentage.  The default is 5.

       MINUTES -- <battery runtime in minutes>
       If MINUTES is specified, during a power failure, apcupsd will  shutdown
       the  system when the remaining remaining runtime on batteries as inter-
       nally calculated by the UPS falls below the time specified. The default
       is 3.


       TIMEOUT -- <time in seconds>
       After  a  power failure, the system will be shutdown after TIMEOUT sec-
       onds have expired.  Normally for SMARTUPSes, this  should  be  zero  so
       that  the  shutdown  time  will  be  determined by the battery level or
       remaining runtime (see above). This command is useful  for  dumb  UPSes
       that  do  not report battery level or the remaining runtime. It is also
       useful for testing apcupsd in that you can force a  rapid  shutdown  by
       setting a small value (e.g. 60) and pulling the plug to the UPS.

       The timeout for the master is always 30 seconds longer than slaves.

       TIMEOUT,  BATTERYLEVEL,  and  MINUTES can be set together without prob-
       lems. The daemon will react to the first case or test  that  is  valid.
       Normally  SmartUPS users will set TIMEOUT to zero so that the system is
       shutdown depending on the percentage  battery  charge  remaining  (BAT-
       TERYLEVEL) or the remaining battery runtime (MINUTES).



   CONFIGURATION COMMANDS FOR SHARING A UPS
       UPSCLASS -- <class of operation>
       [ standalone | shareslave | sharemaster ] and
       [ netslave | netmaster ] are valid types.
       [ standalone | netslave | netmaster ] are tested classes.
       [ shareslave | sharemaster ] classes are being tested.

       The default is "standalone" and should be used for all machines powered
       by the UPS and having a serial port connection to the  UPS,  but  where
       there  are  no other computers dependent power from the same UPS.  This
       is the "normal" case.

       Use "netmaster", if and only if you have a serial  port  connection  to
       the UPS and there are other machines deriving power from the same UPS.

       Use "netslave" if and only if you have no serial port connection to the
       UPS, but you derive power from it.

       Use "shareslave" if and only if you are using a ShareUPS and  connected
       to a BASIC Port with Simple Signal.

       Use  "sharemaster",  if  and  only if you are using a ShareUPS and con-
       nected to the ADVANCED Port Smart Signal control.


       UPSMODE -- [ disable | share | net | sharenet ] are valid types.

       [ disable | net ] are the only known and tested classes.
       [ share | sharenet ] classes are being tested.

       BETA [ share ] For two or seven (2/7) additional simple signal ports on
       a SmartAccessories(tm) (internal/external box) for SmartUPSes.

       NETTIME -- <time in seconds>
       The  rate  in  seconds  that  broadcasts information to Slave machines.
       This rate is reset if there is a power state change. This value is  now
       passed to the slaves to sync. the openning of a socket by the slave for
       the master.

       NETPORT -- <TCP|UDP port number>
       This unix service port number must be set in the /etc/services file  as
       follows:
               tab     tab(spacejunk)  tab     tab
       name                    (stuff)/xxp             #
       apcupsd         NETPORT/tcp             #
       apcupsd         NETPORT/udp             #

       MASTER -- <name of master> for Slave machine.
       The  name  of  the  master which is authorized to send commands to this
       slave.

       SLAVE -- <name of slave(s)> for Master machine.
       The name of the slave machine attached to the  master.   There  can  be
       max. 20 slaves attached to one master.

       USERMAGIC -- < user defined password> for the slave machine.
       The  second level of password security. It must be (17) characters long
       without spaces. This is passed to the master machine during initializa-
       tion  of  sockets.  This  string should be different for each and every
       slave on the network. This is not at all secure as passwords are passed
       in  the  clear.  Please protect your network by firewalling or tcpwrap-
       pers.


SMARTUPS
       If you start getting the follow message:

       Emergency -- Batteries Have Failed!
       Change Them NOW!

       Act upon it quickly. It means what it says.

       Also, not all "SmartUPS" models are eqaully smart.  A  non-NET  or  old
       class  of "SmartUPS" has a subset of the full UPSlink(TM) language, and
       can not be polled for its control codes.

SHAREUPS
       Special note for ShareUPS users, TIMEOUT, BATTERYLEVEL, and MINUTES are
       disabled  or set to default values. Currently, there is not a known way
       for early signals to be sent to BASIC Ports. MINUTES are set to 0.

FILES
       /etc/apcupsd/apcupsd.conf - configuration file.
       /var/log/apcupsd.status - STATUS file
       /var/log/apcupsd.events - where up to the last 50 events are stored for
       the network information server.

EVENTS
       apcupsd  generates events when certain conditions occur such as a power
       failure, batteries exhausted, power return,

       These events are sent to the system log, optionally sent to the  tempo-
       rary  events  file  (/var/log/apcupsd.events), and they also generate a
       call to /etc/apcupsd/apccontrol which in turn will call any scripts you
       have placed in the /etc/apcupsd directory.


DATA format
       If  the DATATIME configuration command is set nonzero, apcupsd will log
       a data record at the interval defined on  the  DATATIME  command.  This
       data record is in a format similar to the PowerChute data file format.


STATUS format
       The  STATUS  output  is in ASCII format and generally there is a single
       piece of information on each line output.  The format varies  based  on
       the type of UPS that you are using.

       DATE     : time and date of last update
       CABLE    : cable type used
       UPSMODEL : ups type or signal method
       UPSMODE  : tells apcupsd what to check
