IPMI-DCMI(8)			System Commands			  IPMI-DCMI(8)

NAME
       ipmi-dcmi - IPMI	DCMI utility

SYNOPSIS
       ipmi-dcmi [OPTION...]

DESCRIPTION
       Ipmi-dcmi is used to execute Data Center	Manageability Interface	(often
       referred	 to  as	 DCM or	DCMI) IPMI extension commands. DCMI extensions
       include support for asset management and	power usage  management.  Most
       will  be	 interested in DCMI for	its power management features. By con-
       figuring	an exception action, power limit, and correction  time	limit,
       power  usage  in	 a data	center can be managed more affectively.	Please
       see --set-power-limit option below for more information.

       DCMI can	also be	configured using the dcmi category in ipmi-config(8).

       The DCMI	specification encompasses many traditional IPMI	features  that
       are  not	 implemented  directly in this tool. Please see	ipmiconsole(8)
       for Serial-over-LAN (SOL) support, ipmi-chassis(8)  for	power  status,
       power  control,	identification,	 and ACPI power	state information, ip-
       mipower(8) for power status and power control, ipmi-sel(8)  for	System
       Event Log (SEL) information, bmc-info(8)	for device and globally	unique
       ID  (guid)  information,	ipmi-sensors(8)	for sensor readings, and ipmi-
       config(8) for configuration.

       Listed below are	general	IPMI options, tool specific  options,  trouble
       shooting	 information,  workaround information, examples, and known is-
       sues. For a general introduction	to FreeIPMI please see freeipmi(7).

GENERAL	OPTIONS
       The following options are general options for configuring IPMI communi-
       cation and executing general tool commands.

       -D IPMIDRIVER, --driver-type=IPMIDRIVER
	      Specify the driver type to use instead of	doing an  auto	selec-
	      tion.   The  currently  available	 outofband drivers are LAN and
	      LAN_2_0, which perform IPMI 1.5 and IPMI 2.0  respectively.  The
	      currently	 available  inband  drivers  are  KCS, SSIF, OPENIPMI,
	      SUNBMC, and INTELDCMI.

       --disable-auto-probe
	      Do not probe in-band IPMI	devices	for default settings.

       --driver-address=DRIVER-ADDRESS
	      Specify the in-band driver address to be	used  instead  of  the
	      probed  value. DRIVER-ADDRESS should be prefixed with "0x" for a
	      hex value	and '0'	for an octal value.

       --driver-device=DEVICE
	      Specify the in-band driver device	path to	be used	instead	of the
	      probed path.

       --register-spacing=REGISTER-SPACING
	      Specify the in-band  driver  register  spacing  instead  of  the
	      probed  value. Argument is in bytes (i.e.	32bit register spacing
	      =	4)

       --target-channel-number=CHANNEL-NUMBER
	      Specify the in-band driver target	channel	number	to  send  IPMI
	      requests to.

       --target-slave-address=SLAVE-ADDRESS
	      Specify  the in-band driver target slave number to send IPMI re-
	      quests to.

       -h IPMIHOST1,IPMIHOST2,..., --hostname=IPMIHOST1[:PORT],IPMI-
       HOST2[:PORT],...
	      Specify the remote host(s) to communicate	with.  Multiple	 host-
	      names  may  be separated by comma	or may be specified in a range
	      format; see HOSTRANGED SUPPORT below. An optional	 port  can  be
	      specified	with each host,	which may be useful in port forwarding
	      or  similar situations.  If specifying an	IPv6 address and port,
	      use the format [ADDRESS]:PORT.

       -u USERNAME, --username=USERNAME
	      Specify the username to use when authenticating with the	remote
	      host.  If	not specified, a null (i.e. anonymous) username	is as-
	      sumed.  The user must have atleast ADMIN privileges in order for
	      this tool	to operate fully.

       -p PASSWORD, --password=PASSWORD
	      Specify the password to use when authenticationg with the	remote
	      host.  If	not specified, a null  password	 is  assumed.  Maximum
	      password length is 16 for	IPMI 1.5 and 20	for IPMI 2.0.

       -P, --password-prompt
	      Prompt  for  password  to	 avoid	possibility  of	 listing it in
	      process lists.

       -k K_G, --k-g=K_G
	      Specify the K_g BMC key to use when authenticating with the  re-
	      mote host	for IPMI 2.0. If not specified,	a null key is assumed.
	      To  input	 the  key  in hexadecimal form,	prefix the string with
	      '0x'. E.g., the key 'abc'	can be entered	with  the  either  the
	      string 'abc' or the string '0x616263'

       -K, --k-g-prompt
	      Prompt  for  k-g	to  avoid possibility of listing it in process
	      lists.

       --session-timeout=MILLISECONDS
	      Specify the session timeout in milliseconds. Defaults  to	 20000
	      milliseconds (20 seconds)	if not specified.

       --retransmission-timeout=MILLISECONDS
	      Specify  the  packet retransmission timeout in milliseconds. De-
	      faults to	1000 milliseconds (1 second) if	not specified. The re-
	      transmission timeout cannot be larger than the session timeout.

       -a AUTHENTICATION-TYPE, --authentication-type=AUTHENTICATION-TYPE
	      Specify the IPMI 1.5 authentication type to use.	The  currently
	      available	 authentication	types are NONE,	STRAIGHT_PASSWORD_KEY,
	      MD2, and MD5. Defaults to	MD5 if not specified.

       -I CIPHER-SUITE-ID, --cipher-suite-id=CIPHER-SUITE-ID
	      Specify the IPMI 2.0 cipher suite	ID to use. The Cipher Suite ID
	      identifies a set of authentication, integrity, and confidential-
	      ity algorithms to	use for	IPMI 2.0 communication.	The  authenti-
	      cation  algorithm	 identifies  the  algorithm to use for session
	      setup, the integrity algorithm identifies	the algorithm  to  use
	      for session packet signatures, and the confidentiality algorithm
	      identifies the algorithm to use for payload encryption. Defaults
	      to  cipher  suite	 ID  3	if not specified. The following	cipher
	      suite ids	are currently supported:

	      0	- Authentication Algorithm = None; Integrity Algorithm = None;
	      Confidentiality Algorithm	= None

	      1	- Authentication Algorithm = HMAC-SHA1;	Integrity Algorithm  =
	      None; Confidentiality Algorithm =	None

	      2	 - Authentication Algorithm = HMAC-SHA1; Integrity Algorithm =
	      HMAC-SHA1-96; Confidentiality Algorithm =	None

	      3	- Authentication Algorithm = HMAC-SHA1;	Integrity Algorithm  =
	      HMAC-SHA1-96; Confidentiality Algorithm =	AES-CBC-128

	      6	 -  Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
	      None; Confidentiality Algorithm =	None

	      7	- Authentication Algorithm = HMAC-MD5; Integrity  Algorithm  =
	      HMAC-MD5-128; Confidentiality Algorithm =	None

	      8	 -  Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
	      HMAC-MD5-128; Confidentiality Algorithm =	AES-CBC-128

	      11 - Authentication Algorithm = HMAC-MD5;	Integrity Algorithm  =
	      MD5-128; Confidentiality Algorithm = None

	      12  - Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
	      MD5-128; Confidentiality Algorithm = AES-CBC-128

	      15 - Authentication Algorithm = HMAC-SHA256; Integrity Algorithm
	      =	None; Confidentiality Algorithm	= None

	      16 - Authentication Algorithm = HMAC-SHA256; Integrity Algorithm
	      =	HMAC_SHA256_128; Confidentiality Algorithm = None

	      17 - Authentication Algorithm = HMAC-SHA256; Integrity Algorithm
	      =	HMAC_SHA256_128; Confidentiality Algorithm = AES-CBC-128

       -l PRIVILEGE-LEVEL, --privilege-level=PRIVILEGE-LEVEL

	      Specify an alternate configuration file.

       -W WORKAROUNDS, --workaround-flags=WORKAROUNDS
	      Specify  workarounds  to	vendor	compliance  issues.   Multiple
	      workarounds can be specified separated by	commas.	A special com-
	      mand  line  flag of "none", will indicate	no workarounds (may be
	      useful for overriding configured defaults). See WORKAROUNDS  be-
	      low for a	list of	available workarounds.

       --debug
	      Turn on debugging.

       -?, --help
	      Output a help list and exit.

       --get-power-limit
	      Get power	limit information.

       --set-power-limit
	      Set power	limit configuration. Can specify configuration via the
	      --exception-actions,	--power-limit-requested,     --correc-
	      tion-time-limit, and --correction-time-limit options listed  be-
	      low.  If	one  or	 more options below are	not specified, current
	      configuration will be utilized.

       --exception-actions=BITMASK
	      Specify exception	actions	for  set  power	 limit	configuration.
	      Special case allowable values: NO_ACTION,	HARD_POWER_OFF_SYSTEM,
	      LOG_EVENT_TO_SEL_ONLY. Other values (e.g.	0x02 through 0x10) are
	      OEM dependent. Used with the --set-power-limit option.

       --power-limit-requested=WATTS
	      Specify  power limit for set power limit configuration. Input is
	      specified	in watts. Used with the	--set-power-limit option.

       --correction-time-limit=MILLISECONDS
	      Specify correction time limit for	set power limit	configuration.
	      Input   is   specified   in   milliseconds.   Used   with	   the
	      --set-power-limit	option.

       --statistics-sampling-period=SECONDS
	      Specify  management  application	statistics sampling period for
	      set power	limit configuration. Input is  specified  in  seconds.
	      Used with	the --set-power-limit option.

       --activate-deactivate-power-limit=OPERATION
	      Activate	or  deactivate	power limit. Allowed values: ACTIVATE,
	      DEACTIVATE.

       --interpret-oem-data
	      Attempt to interpret OEM data, such as event data, sensor	 read-
	      ings,  or	 general  extra	info, etc. If an OEM interpretation is
	      not available, the default output	will be	generated. Correctness
	      of OEM interpretations cannot be	guaranteed  due	 to  potential
	      changes OEM vendors may make in products,	firmware, etc. See OEM
	      INTERPRETATION  below for	confirmed supported motherboard	inter-
	      pretations.

TIME OPTIONS
       By IPMI definition, all IPMI times and timestamps are stored in	local-
       time. However, in many situations, the timestamps will not be stored in
       localtime.  Whether  or not a system truly stored the timestamps	in lo-
       caltime varies on many factors, such as the vendor, BIOS, and operating
       system.

       The following options will allow	the user to adjust the	interpretation
       of the stored timestamps	and how	they should be output.

       --utc-to-localtime
	      Assume  all  times are reported in UTC time and convert the time
	      to localtime before being	output.

       --localtime-to-utc
	      Convert all localtime timestamps to UTC before being output.

       --utc-offset=SECONDS
	      Specify a	specific UTC offset in seconds to be  added  to	 time-
	      stamps.	Value can range	from -86400 to 86400 seconds. Defaults
	      to 0.

HOSTRANGED OPTIONS
       The following options manipulate	hostranged output. See HOSTRANGED SUP-
       PORT below for additional information on	hostranges.

       -B, --buffer-output
	      Buffer hostranged	output.	For each node, buffer standard	output
	      until the	node has completed its IPMI operation. When specifying
	      this  option, data may appear to output slower to	the user since
	      the the entire IPMI operation must complete before any data  can
	      be output.  See HOSTRANGED SUPPORT below for additional informa-
	      tion.

       -C, --consolidate-output
	      Consolidate hostranged output. The complete standard output from
	      every  node  specified  will  be consolidated so that nodes with
	      identical	output are not output twice. A header will list	 those
	      nodes  with  the consolidated output. When this option is	speci-
	      fied, no output can be seen until	the  IPMI  operations  to  all
	      nodes  has  completed.  If  the  user  breaks out	of the program
	      early, all currently consolidated	output	will  be  dumped.  See
	      HOSTRANGED SUPPORT below for additional information.

       -F NUM, --fanout=NUM
	      Specify multiple host fanout. A "sliding window" (or fanout) al-
	      gorithm  is  used	for parallel IPMI communication	so that	slower
	      nodes or timed out nodes will not	impede parallel	communication.
	      The maximum number of threads available at the same time is lim-
	      ited by the fanout. The default is 64.

       -E, --eliminate
	      Eliminate	hosts determined as undetected	by  ipmidetect.	  This
	      attempts to remove the common issue of hostranged	execution tim-
	      ing  out	due  to	 several nodes being removed from service in a
	      large cluster. The ipmidetectd daemon must  be  running  on  the
	      node executing the command.

       --always-prefix
	      Always prefix output, even if only one host is specified or com-
	      municating  in-band. This	option is primarily useful for script-
	      ing purposes. Option will	be ignored if specified	 with  the  -C
	      option.

HOSTRANGED SUPPORT
       Multiple	hosts can be input either as an	explicit comma separated lists
       of  hosts  or  a	 range of hostnames in the general form: prefix[n-m,l-
       k,...], where n < m and l < k, etc. The later form should not  be  con-
       fused  with  regular expression character classes (also denoted by []).
       For example, foo[19] does not represent foo1 or foo9, but rather	repre-
       sents a degenerate range: foo19.

       This range syntax is meant only as a convenience	 on  clusters  with  a
       prefixNN	 naming	 convention  and specification of ranges should	not be
       considered necessary -- the list	foo1,foo9 could	be specified as	 such,
       or by the range foo[1,9].

       Some examples of	range usage follow:
	   foo[01-05] instead of foo01,foo02,foo03,foo04,foo05
	   foo[7,9-10] instead of foo7,foo9,foo10
	   foo[0-3] instead of foo0,foo1,foo2,foo3

       As a reminder to	the reader, some shells	will interpret brackets	([ and
       ])  for	pattern	matching. Depending on your shell, it may be necessary
       to enclose ranged lists within quotes.

       When multiple hosts are specified by the	user, a	thread	will  be  exe-
       cuted  for each host in parallel	up to the configured fanout (which can
       be adjusted via the -F option). This will allow communication to	 large
       numbers of nodes	far more quickly than if done in serial.

       By  default,  standard  output  from each node specified	will be	output
       with the	hostname prepended to each line. Although this output is read-
       able in many situations,	it may be difficult to read  in	 other	situa-
       tions.  For  example, output from multiple nodes	may be mixed together.
       The -B and -C options can be used to change this	default.

       In-band IPMI Communication will be used when the	 host  "localhost"  is
       specified.  This	 allows	 the  user  to add the localhost into the hos-
       tranged output.

GENERAL	TROUBLESHOOTING
       Most often, IPMI	problems are due to configuration problems.

       IPMI over LAN problems involve a	misconfiguration  of  the  remote  ma-
       chine's	BMC.   Double  check to	make sure the following	are configured
       properly	in the remote machine's	BMC: IP	address, MAC  address,	subnet
       mask,  username,	 user enablement, user privilege, password, LAN	privi-
       lege, LAN enablement, and allowed authentication	type(s). For IPMI  2.0
       connections,  double  check  to make sure the cipher suite privilege(s)
       and K_g key are configured properly. The	 ipmi-config(8)	 tool  can  be
       used to check and/or change these configuration settings.

       Inband IPMI problems are	typically caused by improperly configured dri-
       vers or non-standard BMCs.

       In  addition  to	the troubleshooting tips below,	please see WORKAROUNDS
       below to	also if	there are any vendor specific bugs that	have been dis-
       covered and worked around.

       Listed below are	many of	the common issues for error messages.  For ad-
       ditional	support, please	e-mail	the  <freeipmi-users@gnu.org>  mailing
       list.

       "username  invalid"  - The username entered (or a NULL username if none
       was entered) is not available on	the remote machine.  It	 may  also  be
       possible	the remote BMC's username configuration	is incorrect.

       "password  invalid"  - The password entered (or a NULL password if none
       was entered) is not correct. It may also	be possible the	 password  for
       the user	is not correctly configured on the remote BMC.

       "password  verification timeout"	- Password verification	has timed out.
       A "password invalid" error (described  above)  or  a  generic  "session
       timeout"	(described below) occurred.  During this point in the protocol
       it cannot be differentiated which occurred.

       "k_g  invalid" -	The K_g	key entered (or	a NULL K_g key if none was en-
       tered) is not correct. It may also be possible the K_g key is not  cor-
       rectly configured on the	remote BMC.

       "privilege level	insufficient" -	An IPMI	command	requires a higher user
       privilege  than	the one	authenticated with. Please try to authenticate
       with a higher privilege.	This may require authenticating	to a different
       user which has a	higher maximum privilege.

       "privilege level	cannot be obtained for	this  user"  -	The  privilege
       level  you are attempting to authenticate with is higher	than the maxi-
       mum allowed for this user. Please try again with	a lower	privilege.  It
       may  also be possible the maximum privilege level allowed for a user is
       not configured properly on the remote BMC.

       "authentication type unavailable	for attempted privilege	level"	-  The
       authentication  type you	wish to	authenticate with is not available for
       this privilege level. Please try	again with an alternate	authentication
       type or alternate privilege level. It may also be possible  the	avail-
       able  authentication  types you can authenticate	with are not correctly
       configured on the remote	BMC.

       "cipher suite id	unavailable" - The cipher suite	id you wish to authen-
       ticate with is not available on the remote BMC. Please try  again  with
       an alternate cipher suite id. It	may also be possible the available ci-
       pher suite ids are not correctly	configured on the remote BMC.

       "ipmi  2.0 unavailable" - IPMI 2.0 was not discovered on	the remote ma-
       chine. Please try to use	IPMI 1.5 instead.

       "connection timeout" - Initial IPMI communication failed. A  number  of
       potential errors	are possible, including	an invalid hostname specified,
       an  IPMI	 IP address cannot be resolved,	IPMI is	not enabled on the re-
       mote server, the	network	connection is bad, etc.	Please verify configu-
       ration and connectivity.

       "session	timeout" - The IPMI session has	timed out.  Please  reconnect.
       If this error occurs often, you may wish	to increase the	retransmission
       timeout.	Some remote BMCs are considerably slower than others.

       "device	not  found"  - The specified device could not be found.	Please
       check configuration or inputs and try again.

       "driver timeout"	- Communication	with the driver	or  device  has	 timed
       out. Please try again.

       "message	 timeout"  - Communication with	the driver or device has timed
       out. Please try again.

       "BMC busy" - The	BMC is currently busy. It may be  processing  informa-
       tion  or	have too many simultaneous sessions to manage. Please wait and
       try again.

       "could not find inband device" -	An inband device could not  be	found.
       Please  check configuration or specify specific device or driver	on the
       command line.

       "driver timeout"	- The inband driver has	timed out communicating	to the
       local BMC or service processor. The BMC or  service  processor  may  be
       busy or (worst case) possibly non-functioning.

       "internal  IPMI	error" - An IPMI error has occurred that FreeIPMI does
       not know	how to handle. Please e-mail <freeipmi-users@gnu.org>  to  re-
       port the	issue.

WORKAROUNDS
       With  so	 many different	vendors	implementing their own IPMI solutions,
       different vendors may implement their IPMI protocols  incorrectly.  The
       following describes a number of workarounds currently available to han-
       dle  discovered compliance issues. When possible, workarounds have been
       implemented so they will	be transparent to the user. However, some will
       require the user	to specify a workaround	be used	via the	-W option.

       The hardware listed below may only indicate the hardware	that a problem
       was discovered on. Newer	versions of hardware may fix the problems  in-
       dicated below. Similar machines from vendors may	or may not exhibit the
       same  problems.	Different  vendors may license their firmware from the
       same  IPMI  firmware  developer,	 so  it	 may  be  worthwhile  to   try
       workarounds listed below	even if	your motherboard is not	listed.

       If  you	believe	 your hardware has an additional compliance issue that
       needs a workaround to be	implemented, please contact the	FreeIPMI main-
       tainers on <freeipmi-users@gnu.org> or <freeipmi-devel@gnu.org>.

       assumeio	- This workaround flag will assume inband interfaces  communi-
       cate  with  system  I/O rather than being memory-mapped.	This will work
       around systems that report invalid base addresses. Those	 hitting  this
       issue  may see "device not supported" or	"could not find	inband device"
       errors.	Issue observed on HP ProLiant DL145 G1.

       spinpoll	- This workaround flag will inform some	inband	drivers	 (most
       notably	the  KCS driver) to spin while polling rather than putting the
       process to sleep. This may significantly	improve	the wall clock running
       time of tools because an	operating system scheduler's  granularity  may
       be  much	larger than the	time it	takes to perform a single IPMI message
       transaction. However, by	spinning, your system may be  performing  less
       useful work by not contexting out the tool for a	more useful task.

       authcap	- This workaround flag will skip early checks for username ca-
       pabilities, authentication capabilities,	and K_g	support	and allow IPMI
       authentication to succeed. It works around multiple issues in which the
       remote system does not properly report username capabilities, authenti-
       cation capabilities, or K_g status. Those hitting this  issue  may  see
       "username  invalid",  "authentication  type  unavailable	 for attempted
       privilege level", or "k_g invalid"  errors.   Issue  observed  on  Asus
       P5M2/P5MT-R/RS162-E4/RX4,    Intel   SR1520ML/X38ML,   and   Sun	  Fire
       2200/4150/4450 with ELOM.

       nochecksumcheck - This workaround flag will tell	FreeIPMI to not	 check
       the  checksums  returned	 from  IPMI command responses. It works	around
       systems that return invalid checksums due to implementation errors, but
       the packet is otherwise valid. Users are	cautioned on the use  of  this
       option,	as  it	removes	 validation of packet integrity	in a number of
       circumstances. However, it is unlikely to be an issue  in  most	situa-
       tions.  Those hitting this issue	may see	"connection timeout", "session
       timeout", or "password verification timeout" errors. On IPMI  1.5  con-
       nections,  the  "noauthcodecheck" workaround may	also needed too. Issue
       observed	on Supermicro X9SCM-iiF, Supermicro  X9DRi-F,  and  Supermicro
       X9DRFR.

       idzero  -  This	workaround flag	will allow empty session IDs to	be ac-
       cepted by the client. It	works around IPMI sessions that	 report	 empty
       session	IDs  to	 the client. Those hitting this	issue may see "session
       timeout"	errors.	Issue observed on Tyan S2882 with M3289	BMC.

       unexpectedauth -	This workaround	flag will  allow  unexpected  non-null
       authcodes  to  be checked as though they	were expected. It works	around
       an issue	when packets contain non-null authentication  data  when  they
       should  be  null	due to disabled	per-message authentication. Those hit-
       ting this issue may see "session	timeout"  errors.  Issue  observed  on
       Dell PowerEdge 2850,SC1425. Confirmed fixed on newer firmware.

       forcepermsg  -  This workaround flag will force per-message authentica-
       tion to be used no matter what is advertised by the remote  system.  It
       works  around an	issue when per-message authentication is advertised as
       disabled	on the remote system, but it is	actually required for the pro-
       tocol. Those hitting this issue may see "session	timeout" errors.   Is-
       sue observed on IBM eServer 325.

       endianseq  -  This  workaround flag will	flip the endian	of the session
       sequence	numbers	to allow the session to	continue  properly.  It	 works
       around  IPMI  1.5  session  sequence numbers that are the wrong endian.
       Those hitting this issue	may see	"session timeout"  errors.  Issue  ob-
       served on some Sun ILOM 1.0/2.0 (depends	on service processor endian).

       noauthcodecheck	- This workaround flag will tell FreeIPMI to not check
       the authentication codes	returned from IPMI 1.5 command	responses.  It
       works  around  systems  that return invalid authentication codes	due to
       hashing or implementation errors. Users are cautioned  on  the  use  of
       this option, as it removes an authentication check verifying the	valid-
       ity of a	packet.	However, in most organizations,	this is	unlikely to be
       a  security  issue.  Those hitting this issue may see "connection time-
       out", "session timeout",	or  "password  verification  timeout"  errors.
       Issue  observed	on  Xyratex FB-H8-SRAY,	Intel Windmill,	Quanta Winter-
       fell, and Wiwynn	Windmill.

       intel20 - This workaround flag will work	around several Intel IPMI  2.0
       authentication issues. The issues covered include padding of usernames,
       and  password  truncation  if  the  authentication  algorithm  is HMAC-
       MD5-128.	Those hitting this issue may see "username invalid", "password
       invalid", or "k_g invalid" errors. Issue	observed  on  Intel  SE7520AF2
       with Intel Server Management Module (Professional Edition).

       supermicro20 - This workaround flag will	work around several Supermicro
       IPMI  2.0  authentication  issues  on  motherboards  w/	Peppercon IPMI
       firmware. The issues covered include handling invalid length  authenti-
       cation  codes.  Those hitting this issue	may see	"password invalid" er-
       rors.  Issue observed on	Supermicro H8QME  with	SIMSO  daughter	 card.
       Confirmed fixed on newerver firmware.

       sun20 - This workaround flag will work work around several Sun IPMI 2.0
       authentication issues. The issues covered include invalid lengthed hash
       keys,  improperly  hashed keys, and invalid cipher suite	records. Those
       hitting this issue may see "password invalid" or	 "bmc  error"  errors.
       Issue  observed	on Sun Fire 4100/4200/4500 with	ILOM.  This workaround
       automatically includes the "opensesspriv" workaround.

       opensesspriv - This workaround flag will	slightly alter FreeIPMI's IPMI
       2.0 connection protocol to workaround an	invalid	hashing	algorithm used
       by the remote system. The privilege level sent during the Open  Session
       stage of	an IPMI	2.0 connection is used for hashing keys	instead	of the
       privilege  level	 sent during the RAKP1 connection stage. Those hitting
       this issue may see "password invalid",  "k_g  invalid",	"bad  rmcpplus
       status code", or	"privilege level cannot	be obtained for	this user" er-
       rors.   Issue  observed	on Sun Fire 4100/4200/4500 with	ILOM, Inventec
       5441/Dell  Xanadu  II,  Supermicro  X8DTH,  Supermicro	X8DTG,	 Intel
       S5500WBV/Penguin	 Relion	 700,  Intel  S2600JF/Appro 512X, Quanta QSSC-
       S4R/Appro GB812X-CN, Dell C5220,	and the	OpenIPMI  software  BMC.  This
       workaround is automatically triggered with the "sun20" workaround.

       integritycheckvalue  - This workaround flag will	work around an invalid
       integrity check value during an IPMI 2.0	session	establishment when us-
       ing Cipher Suite	ID 0. The integrity check value	should	be  0  length,
       however	the  remote motherboard	responds with a	non-empty field. Those
       hitting this issue may see "k_g invalid"	errors.	Issue observed on  Su-
       permicro	 X8DTG,	 Supermicro  X8DTU,  and Intel S5500WBV/Penguin	Relion
       700, and	Intel S2600JF/Appro 512X.

       No IPMI 1.5 Support - Some motherboards that support IPMI 2.0 have been
       found to	not support IPMI 1.5. Those hitting this issue may  see	 "ipmi
       2.0  unavailable"  or  "connection  timeout"  errors. This issue	can be
       worked around by	using IPMI 2.0	instead	 of  IPMI  1.5	by  specifying
       --driver-type=LAN_2_0.  Issue observed on a number of HP	and Supermicro
       motherboards.

OEM INTERPRETATION
       The following motherboards are confirmed	to have	atleast	 some  support
       by  the --interpret-oem-data option. While highly probable the OEM data
       interpretations would work across other motherboards by the same	 manu-
       facturer,  there	 are no	guarantees. Some of the	motherboards below may
       be rebranded by vendors/distributors.

       Currently None

EXAMPLES
       # ipmi-dcmi --get-power-limit

       Get power limit of the local machine.

       # ipmi-dcmi -h ahost -u myusername -p mypassword	--get-power-limit

       Get power limit of a remote machine using IPMI over LAN.

       # ipmi-dcmi -h mycluster[0-127]	-u  myusername	-p  mypassword	--get-
       power-limit

       Get power limit across a	cluster	using IPMI over	LAN.

DIAGNOSTICS
       Upon  successful	 execution, exit status	is 0. On error,	exit status is
       1.

       If multiple hosts are specified for communication, the exit status is 0
       if and only if all targets successfully	execute.  Otherwise  the  exit
       status is 1.

KNOWN ISSUES
       On  older  operating systems, if	you input your username, password, and
       other potentially security relevant information on  the	command	 line,
       this information	may be discovered by other users when using tools like
       the  ps(1) command or looking in	the /proc file system. It is generally
       more secure to input password information with options like the	-P  or
       -K  options.  Configuring security relevant information in the FreeIPMI
       configuration file would	also be	an appropriate way to hide this	infor-
       mation.

       In order	to prevent brute force attacks,	 some  BMCs  will  temporarily
       "lock  up" after	a number of remote authentication errors. You may need
       to wait awhile in order to this temporary "lock up" to pass before  you
       may authenticate	again.
