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.  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
              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 clearing 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.

       --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.

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, 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  number  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.

       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  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  manufacturer,  there  are  no  guarantees. Some of the

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.
