NAME

       IPMI - IPMI Platform Event Trap Interpreter

SYNOPSIS

       ipmi-pet [OPTION...] [SPECIFIC TRAP] [VARIABLE BINDING HEX BYTES ...]

DESCRIPTION

       Ipmi-pet  interprets  hex  bytes  from  a  platform  event trap (PET) and outputs a string
       representing its contents. Hex values may be input on the command line,  a  file  via  the
       --file  option,  or  via  stdin  if  neither  of  the previous are specified.  Ipmi-pet is
       commonly used in conjunction with an SNMP trap daemon to intrepret  the  results  from  an
       IPMI  PET trap captured by the daemon. While ipmi-pet could be called directly from such a
       daemon, typically a script is called to parse the SNMP daemon's output and convert it into
       a  form that can be input into ipmi-pet.  On some systems, you may wish to also send a PET
       acknowledge to a remote system to inform it the trap was received and parsed. One  can  be
       sent  using  the  --pet-acknowledge  option.   While  an  IPMI  session is not required to
       interpret a PET, data from the sensor  data  repository  (SDR)  is  required  to  properly
       interpret sensor names and other information in the PET. IPMI session configuration below,
       such as driver, hostname, username, etc. should be configured to load the SDR of the  host
       where  the  trap originated.  If this is difficult to perform, it may be wise to cache and
       load a specific SDR cache using the --sdr-cache-file option.  If the SDR is  difficult  to
       obtain,  the --ignore-sdr-cache option can be specified so that an SDR will not be loaded,
       and an IPMI session will not be required. The PET will be interpreted as best as  possible
       given   no   SDR.   The  --ignore-sdr-cache  option  may  affect  other  options  such  as
       --interpret-oem-data too. Some options, such as  --manufacturer-id  and  --product-id  may
       alleviate some of these issues.  If the SNMP daemon does not output a SNMPv1 specific trap
       on its own, it is typically output as the last element of the OID in SNMPv2.  If for  some
       reason a specific trap cannot be determined, the value of NA may be input for the specific
       trap to indicate it is not available.  Ipmi-pet will output as much as possible  based  on
       the  variable  bindings information. Some of the specific trap information may be obtained
       via SDR information.

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

GENERAL OPTIONS

       The following options are general options for configuring IPMI communication and executing
       general tool commands.

       -D IPMIDRIVER, --driver-type=IPMIDRIVER
              Specify  the  driver type to use instead of doing an auto selection.  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 requests to.

       -h IPMIHOST, --hostname=IPMIHOST[:PORT]
              Specify the remote host to communicate with. An optional  port  can  be  specified,
              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 assumed. The user must have atleast
              OPERATOR 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 remote  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.  Defaults  to  1000
              milliseconds  (1  second)  if  not  specified. The retransmission 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 confidentiality algorithms to use for IPMI 2.0
              communication. The authentication 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 the privilege level to be used. The currently  available  privilege  levels
              are USER, OPERATOR, and ADMIN. Defaults to OPERATOR if not specified.

       --config-file=FILE
              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 command line flag of "none", will indicate
              no  workarounds (may be useful for overriding configured defaults). See WORKAROUNDS
              below for a list of available workarounds.

       --debug
              Turn on debugging.

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

       --usage
              Output a usage message and exit.

       -V, --version
              Output the program version and exit.

IPMI-PET OPTIONS

       The following options are specific to ipmi-pet.

       -v     Output verbose output. This option will  output  event  direction  and  OEM  custom
              messages from the trap.

       -vv    Output  very  verbose  output.  This  option  will  output  additional  information
              available in the trap, such as GUID, manufacturer ID, and system ID.

       -vvv   Output very very verbose output. This option  will  output  additional  information
              than  verbose  output.  Most  notably  it will output additional hex codes to given
              information on ambiguous events. For example, it will output Generator ID hex codes
              for sensors without names.

       --pet-acknowledge
              Send  PET  acknowledge using inputted trap data instead of outputting data. In some
              circumstances, this may be useful to  inform  a  remote  system  that  a  trap  was
              received  and  parsed.  If  specified,  a  hostname  must  be  specified  via -h or
              --hostname to inform ipmi-pet where to send the acknowledge to. When this option is
              specified, the SDR cache is not loaded and is not required.

       --file=CMD-FILE
              Specify  a file to read PET specific trap and variable bindings hex from instead of
              command line.

       --output-event-severity
              Output event severity in output. This will add an additional  output  of  an  event
              severity.  The  outputs  may  be  Monitor, Information, OK, Non-critical condition,
              Critical condition, or Non-recoverable condition. This differs from the  output  of
              --output-event-state,  as event severity is not interpreted, it is a value reported
              in the SNMP  trap.  However,  not  all  events  may  report  a  severity,  or  some
              manufacturers  may  not  support  the  report  of  a  severity. Event severity will
              automatically be output under verbose output.

       --output-event-state
              Output event state in output. This will add an additional output  reporting  if  an
              event  should  be  viewed  as  NOMINAL, WARNING, or CRITICAL. This differs from the
              output of --output-event-severity, as this output is an interpreted value that will
              be  interpreted  identically to the --output-event-state output in ipmi-sel(8).  As
              long as an event interpretation is supported, all events will have outputted state.
              The   event  state  is  an  interpreted  value  based  on  the  configuration  file
              /etc/freeipmi//freeipmi_interpret_sel.conf   and   the   event    direction.    See
              freeipmi_interpret_sel.conf(5) for more information.

       --event-state-config-file=FILE
              Specify   an   alternate   event   state  configuration  file.  Option  ignored  if
              --output-event-state not specified.

       --manufacturer-id=NUMBER
              Specify a specific manufacturer id  to  assume.  Useful  if  you  wish  to  specify
              --interpret-oem-data,  but  the manufacturer id cannot be determined by IPMI access
              or is not available in the SNMP trap.  The manufacturer id of a motherboard can  be
              determined with bmc-info(8).  If this option is specified, so must --product-id.

       --product-id=NUMBER
              Specify   a  specific  product  id  to  assume.  Useful  if  you  wish  to  specify
              --interpret-oem-data, but the product id cannot be determined by IPMI access or  is
              not  available in the SNMP trap.  The product id of a motherboard can be determined
              with bmc-info(8).  If this option is specified, so must --manufacturer-id.

       --interpret-oem-data
              Attempt to interpret OEM data, such as event  data,  sensor  readings,  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 interpretations.

       --entity-sensor-names
              Output sensor names  prefixed  with  their  entity  id  and  instance  number  when
              appropriate.  This  may  be  necessary  on  some motherboards to help identify what
              sensors are referencing. For example, a motherboard may have multiple sensors named
              'TEMP'.  The  entity id and instance number may help clarify which sensor refers to
              "Processor 1" vs. "Processor 2".

       --no-sensor-type-output
              Do not show sensor type output for each entry. On many systems, the sensor type  is
              redundant   to   the   name   of  the  sensor.  This  can  especially  be  true  if
              --entity-sensor-names is specified.  If the sensor name is sufficient,  or  if  the
              sensor type is of no interest to the user, this option can be specified to condense
              output.

       --comma-separated-output
              Output fields in comma separated format.

       --no-header-output
              Do not output column headers. May be useful in scripting.

       --non-abbreviated-units
              Output  non-abbreviated  units  (e.g.  'Amps'  instead  of   'A').   May   aid   in
              disambiguation of units (e.g. 'C' for Celsius or Coulombs).

SDR CACHE OPTIONS

       This tool requires access to the sensor data repository (SDR) cache for general operation.
       By default, SDR data will be downloaded and cached on the  local  machine.  The  following
       options apply to the SDR cache.

       --flush-cache
              Flush  a  cached  version  of  the  sensor  data repository (SDR) cache. The SDR is
              typically cached for faster subsequent access. However, it may need to  be  flushed
              and re-generated if the SDR has been updated on a system.

       --quiet-cache
              Do  not  output  information  about  cache  creation/deletion.  May  be  useful  in
              scripting.

       --sdr-cache-recreate
              If the SDR cache is out of date or invalid, automatically recreate the sensor  data
              repository (SDR) cache. This option may be useful for scripting purposes.

       --sdr-cache-file=FILE
              Specify  a  specific  sensor  data repository (SDR) cache file to be stored or read
              from. If this option is used when multiple hosts are specified, the same SDR  cache
              file will be used for all hosts.

       --sdr-cache-directory=DIRECTORY
              Specify an alternate directory for sensor data repository (SDR) caches to be stored
              or read from. Defaults to the home directory if not specified.

       --ignore-sdr-cache
              Ignore SDR cache  related  processing.  May  lead  to  incomplete  or  less  useful
              information  being  output, however it will allow functionality for systems without
              SDRs or when the correct SDR cannot be loaded.

GENERAL TROUBLESHOOTING

       Most often, IPMI problems are due to configuration problems.

       IPMI over LAN problems involve a misconfiguration of the  remote  machine'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   privilege,  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 drivers 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 discovered and worked around.

       Listed below are many of the common issues for error messages.   For  additional  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 entered) is not
       correct. It may also be possible the K_g key is not correctly  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 maximum 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  available  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 authenticate with  is  not
       available  on  the  remote BMC. Please try again with an alternate cipher suite id. It may
       also be possible the available cipher suite ids are not correctly configured on the remote
       BMC.

       "ipmi  2.0 unavailable" - IPMI 2.0 was not discovered on the remote machine. 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 remote server, the  network  connection  is  bad,  etc.  Please
       verify configuration 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 information 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 report 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  handle 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 indicated  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  maintainers  on  <freeipmi-users@gnu.org>  or
       <freeipmi-devel@gnu.org>.

       assumeio  - This workaround flag will assume inband interfaces communicate 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 capabilities,
       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, authentication 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 situations. Those
       hitting  this  issue  may  see  "connection  timeout",  "session  timeout",  or  "password
       verification  timeout"  errors.  On IPMI 1.5 connections, 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 accepted 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 hitting 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 authentication 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 protocol. Those hitting this  issue  may  see  "session  timeout"  errors.   Issue
       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 observed 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 validity of
       a packet. However, in most organizations, this is unlikely to be a security  issue.  Those
       hitting  this  issue  may  see  "connection  timeout",  "session  timeout",  or  "password
       verification timeout" errors.  Issue  observed  on  Xyratex  FB-H8-SRAY,  Intel  Windmill,
       Quanta Winterfell, 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  authentication codes. Those hitting this issue may see
       "password invalid" errors.  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", or "bad rmcpplus status
       code" errors.  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, and Dell C5220.  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 using 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 Supermicro
       X8DTG,  Supermicro  X8DTU,  and Intel S5500WBV/Penguin Relion 700, and Intel S2600JF/Appro
       512X.

       assumemaxsdrrecordcount - This workaround will inform SDR reading to stop reading after  a
       known maximum numer of SDR records have been read. This will work around systems that have
       mis-implemented SDR reading functions. Those hitting this issue may see "SDR record  count
       invalid" errors. Issue observed on unspecified Inspur motherboard.

       malformedack  -  This  workaround flag will ignore malformed PET acknowledge responses and
       assume any PET acknowledge response from the remote machine  is  valid.  It  works  around
       remote  systems  that  respond  with  PET acknowledge requests with invalid/malformed IPMI
       payloads.  Those hitting this issue may see "session timeout" errors when executing a  PET
       acknowledge. Issue observed on Dell Poweredge R610.

       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 HP Proliant DL 145.

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  manufacturer,  there  are  no  guarantees.  Some  of  the
       motherboards below may be rebranded by vendors/distributors.

       Currently None

DIAGNOSTICS

       Upon successful execution, exit status is 0. On error, 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 information.

       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.
