NAME

       ipmi-sel - display SEL entries

SYNOPSIS

       ipmi-sel [OPTION...]

DESCRIPTION

       Ipmi-sel  is  used  to  view  and manage System Event Log (SEL) entries. SEL records store
       system event information and may be useful for  debugging  problems.   Ipmi-sel  does  not
       inform  the  user  if  an event is particularly good or bad, just that the event occurred.
       Users may wish to use the --output-event-state option to output the analyzed state.

       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).  To perform some advanced SEL management,
       please see bmc-device(8).

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 IPMIHOST1,IPMIHOST2,..., --hostname=IPMIHOST1[:PORT],IPMIHOST2[:PORT],...
              Specify the remote host(s) to communicate with. Multiple hostnames 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.

       -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
              USER 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-SEL OPTIONS

       The following options are specific to Ipmi-sel.

       -v     Output verbose output. This option will output event  direction.   Event  direction
              may  be  useful  to  differentiate  severity between some events. For example, some
              motherboards may issue an event both when a temperature  exceeds  a  threshold  and
              when it goes back down below it.

       -vv    Output  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  SEL  entries,  such  as OEM codes. For example, it will
              output Generator ID hex codes for sensors without names, event type codes  for  OEM
              events, and record types for OEM records. This information may be useful if you are
              writing a parser outside of ipmi-sel to interpret OEM information.

       -i, --info
              Show general information about the SEL.

       --display=RECORD-IDS-LIST
              Display SEL records by record id. Accepts space or comma separated lists.

       --exclude-display=RECORD-IDS-LIST
              Exclude display of SEL records by record  id.  Accepts  space  or  comma  separated
              lists.

       --display-range=START-END
              Display SEL records from record id START to END.

       --exclude-display-range=START-END
              Exclude display of SEL records from record id START to END.

       --date-range=DATE-DATE
              Display  SEL  records with events occurring in the specified date range.  Dates may
              be specified in MM/DD/YYYY or MM-DD-YYYY format. The month may be  specified  as  a
              numeral  or  its  abbreviated  string  name.  The  current local system time can be
              specified with "now". Note that  non-timestamped  records  will  not  be  displayed
              automatically because they do not possess a timestamp.

       --exclude-date-range=DATE-DATE
              Exclude  display  of SEL records with events occurring in the specified date range.
              Dates may be specified in  MM/DD/YYYY  or  MM-DD-YYYY  format.  The  month  may  be
              specified  as  a  numeral  or its abbreviated string name. The current local system
              time can be specified  with  "now".  Note  that  non-timestamped  records  will  be
              displayed automatically because they do not possess a timestamp.

       -t SENSOR-TYPE-LIST, --sensor-types=SENSOR-TYPE-LIST
              Specify  sensor  types  to  show SEL events for. Multiple types can be separated by
              commas or spaces. A special command line type of "all",  will  indicate  all  types
              should  be  shown  (may  be  useful  for overriding configured defaults). Users may
              specify sensor types  by  string  (see  --list-sensor-types  below)  or  by  number
              (decimal or hex).

       -T SENSOR-TYPE-LIST, --exclude-sensor-types=SENSOR-TYPE-LIST
              Specify sensor types to not show SEL events for. Multiple types can be separated by
              commas or spaces. A special command line type of "none",  will  indicate  no  types
              should  be  excluded  (may be useful for overriding configured defaults). Users may
              specify sensor types  by  string  (see  --list-sensor-types  below)  or  by  number
              (decimal or hex).

       -L, --list-sensor-types
              List sensor types.

       --tail=count
              Display  approximately  the last count SEL records. The display count is calculated
              by approximating the record ids of the last SEL records. It's  correctness  depends
              highly on the SEL implementation by the vendor.

       --clear
              Clear SEL.

       --post-clear
              Identical  to  --clear,  except the SEL clearning will be performed after SEL event
              records are displayed. This option is useful for scripting if users intend  to  log
              SEL  events  to  another log, then immediately clear SEL. Unlike calling --clear in
              another execution of ipmi-sel, this option will use SEL reservations to notify  the
              user  if  a SEL change has occurred while displaying and clearing the SEL. This can
              protect users from a race, where a new SEL event is  unknowingly  generated  before
              clearing  the SEL. Note that SEL reservations are optionally implemented by vendors
              and may not be available on all machines.

       --delete=RECORD-IDS-LIST
              Delete records by record id in the SEL. Accepts space or comma separated lists.

       --delete-range=START-END
              Delete record ids from START to END in the SEL.

       --system-event-only
              Output only system event records (i.e. don't output OEM records).

       --oem-event-only
              Output only OEM event records (i.e. don't output system event records).

       --output-manufacturer-id
              For OEM SEL record types, output the manufacturer ID along  with  event  data  when
              available.

       --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.  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.

       --hex-dump
              Hex-dump SEL entries.

       --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.

       --output-oem-event-strings
              Some motherboards support an IPMI OEM extension that returns the string output  for
              a  system  event.  Such string output may be beneficial for determining the meaning
              behind OEM specific events. This option will use the OEM event string  to  describe
              all   system   events   in   the   ipmi-sel   output.   This  option  differs  from
              --interpret-oem-data option in that  all  system  events  will  output  the  vendor
              supplied  event string, not just events that are OEM specific. The event string may
              be very different from the normal FreeIPMI event string output.  If  an  OEM  event
              strings  is  not  available,  the  default  output  will be output.  This option is
              confirmed to work for Fujitsu iRMC S1 and iRMC S2 systems.

       --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).

       --legacy-output
              Output in legacy format. Newer options may not be applicable to legacy output.

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.

       -f, --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.

       -Q, --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.

TIME OPTIONS

       By IPMI definition, all IPMI times and timestamps are stored  in  localtime.  However,  in
       many  situations,  the timestamps will not be stored in localtime. Whether or not a system
       truly stored the timestamps in localtime 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 timestamps.  Value can
              range from -86400 to 86400 seconds. Defaults to 0.

HOSTRANGED OPTIONS

       The following options manipulate hostranged  output.  See  HOSTRANGED  SUPPORT  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 information.

       -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  specified, 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) algorithm 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
              limited 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 timing 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 communicating  in-band.
              This  option  is primarily useful for scripting 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 confused with  regular  expression  character  classes  (also
       denoted  by  []).  For  example,  foo[19]  does  not  represent  foo1  or foo9, but rather
       represents 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 executed 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 readable in many situations, it may be
       difficult to read in other situations. 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 hostranged output.

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.

IPMI-SEL TROUBLESHOOTING

       Some  timestamps in the SEL may report a date of 1-Jan-1970, the epoch for SEL timestamps.
       This timestamp is not necessarily incorrect. It usually indicates a  hardware  event  that
       occurred  before  a  timestamp  in  firmware  has  been  initialized. For example, certain
       hardware components will have their internal clocks reset during a power cycle.

       However, if the internal clock of the SEL appears to be regularly incorrect, you may  need
       to set the SEL time. This can be done using bmc-device(8).

       The following are common SEL related messages.

       "sel  config  file  parse error" - A parse error was found in the sel event interpretation
       configuration file. Please see freeipmi_interpret_sel.conf(5).

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, and Quanta QSSC-S4R/Appro GB812X-CN. 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 that. Those hitting this issue may see "SDR record
       count invalid" errors. Issue observed on unspecified Inspur motherboard.

       assumesystemevent - This workaround option will assume invalid SEL record types are system
       event  records.  Records may be formatted correctly but report invalid record types. Those
       hitting this issue may see "Unknown SEL Record Type" errors. Output may be  unknown,  pray
       for  the  best. This option is confirmed to work around compliances issues on HP DL 380 G5
       motherboards.

       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.

EXAMPLES

       # ipmi-sel

       Show all SEL records on the local machine.

       # ipmi-sel -h ahost -u myusername -p mypassword

       Show all SEL records of a remote machine using IPMI over LAN.

       # ipmi-sel -h mycluster[0-127] -u myusername -p mypassword

       Show all SEL records across a cluster using IPMI over LAN.

       # ipmi-sel --delete=44,82

       Delete SEL records 44 and 82 on the local machine.

       # ipmi-sel --delete-all

       Delete all SEL entries on the local machine.

       # ipmi-sel --delete-range=12-42

       Delete SEL entries in the range 12 to 42 on the local machine.

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 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.
