NAME

       ipmiseld - IPMI SEL logging daemon

SYNOPSIS

       ipmiseld [OPTION...]

DESCRIPTION

       The  ipmiseld  daemon  polls  the  system event log (SEL) of specified hosts and stores the logs into the
       local syslog. By default, the daemon can also make best efforts to manage  the  remote  SEL's  buffer  to
       ensure  events  are  never lost. Recent logging data will be cached to disk to ensure that SEL events are
       not missed in the event the client or server is rebooted.

       Many of the options for this daemon are very similar to the ipmi-sel(8) tool. It can be configured to log
       the  local  host,  a  remote  host, or a range of hosts to the local syslog. It can be configured via the
       command line arguments listed below or via the /etc/freeipmi//ipmiseld.conf configuration file.

       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 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.

IPMISELD OPTIONS

       The following options are specific to ipmiseld.

       -v     Log verbose information. This option will log additional information.  Most notably it will output
              additional hex codes to given information on ambiguous SEL entries or SEL records. For example, it
              will output Generator ID hex codes for sensors without names. Additional non-critical  SEL  errors
              or issues will also be logged. Somewhat common errors, such as timeouts or invalid hostnames, will
              output with increased verbosity.

       -t SENSOR-TYPE-LIST, --sensor-types=SENSOR-TYPE-LIST
              Specify sensor types of SEL events to log. By default, all sensor  types  are  logged.  A  special
              command  line type of "all", will indicate all types should be shown (may be useful for overriding
              configured defaults). Multiple types can be separated by commas  or  spaces.   Users  may  specify
              sensor types by string (see --list-sensor-types in ipmi-sel(8)) or by number (decimal or hex).

       -T SENSOR-TYPE-LIST, --exclude-sensor-types=SENSOR-TYPE-LIST
              Specify sensor types of SEL events to not log. By default, no sensor types are filtered. A special
              command line type of "none", will indicate  no  types  should  be  excluded  (may  be  useful  for
              overriding  configured  defaults).  Multiple types can be separated by commas or spaces. Users may
              specify sensor types by string (see --list-sensor-types in ipmi-sel(8)) or by number  (decimal  or
              hex).

       --system-event-only
              Log only system event records (i.e. don't log OEM records).

       --oem-event-only
              Log only OEM event records (i.e. don't log system event records).

       --event-state-config-file=FILE
              Specify an alternate event state configuration file.

       --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".

       --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).

       --event-state-filter=FILTERSTRING
              Specify event states to be filtered out and not logged.  Possible  inputs  are  NOMINAL,  WARNING,
              CRITICAL,  and  NA.  Multiple  states  can be listed separted by comma. The special case string of
              "none" will indicate no event states should be excluded (may be useful for  overriding  configured
              defaults).

       --warning-threshold=PERCENTINT
              Specify  SEL  fullness  warning  threshold  as  an  integer  percentage. When the SEL is past this
              percentage full, a warning will be output indicating that SEL is nearly full. Specify 0 to disable
              warning logs. Defaults to 80.

       --clear-threshold=PERCENTINT
              Specify  SEL  fullness  clear  threshold  as  an  integer  percentage.  When  the SEL is past this
              percentage full, ipmiseld will attempt to clear the SEL. Specify 0 to disable clearing.  When  the
              SEL  is  full,  it will be the responsibility of the user to clear the SEL manually if clearing is
              disabled. Defaults to 0. If specified to a non-zero value, be careful that the clearing of the SEL
              could  affect  other  applications  that monitor the SEL, such as monitoring applications that use
              ipmi-sel(8) or libipmimonitoring(3).

       --system-event-format=FORMATSTRING
              Specify the format of the log output when a SEL system event  is  encountered.  Defaults  to  "SEL
              System  Event:  %d, %t, %s, %I, %E" if logging locally, "SEL System Event(%h): %d, %t, %s, %I, %E"
              if logging outofband or with hostranges. See SEL LOG FORMAT STRING below for formatting details.

       --oem-timestamped-event-format=FORMATSTRING
              Specify the format of the log output when a SEL OEM timestamped event is encountered. Defaults  to
              "SEL OEM Event: %d, %t, %I, %o" if logging locally, "SEL OEM Event(%h): %d, %t, %I, %o" if logging
              outofband or with hostranges.. See SEL LOG FORMAT STRING below for formatting details.

       --oem-non-timestamped-event-format=FORMATSTRING
              Specify the format of the log output when a SEL OEM non-timestamped event is encountered. Defaults
              to "SEL OEM Event: %I, %o" if logging locally, "SEL OEM Event(%h): %I, %o" if logging outofband or
              with hostranges.. See SEL LOG FORMAT STRING below for formatting details.

       --poll-interval=SECONDS
              Specify the poll interval to check the SEL for  new  events.  Defaults  to  300  seconds  (i.e.  5
              minutes).

       --log-facility=STRING
              Specify  the  log  facility to use. Defaults to LOG_DAEMON. Legal inputs are LOG_DAEMON, LOG_USER,
              LOG_LOCAL0, LOG_LOCAL1, LOG_LOCAL2, LOG_LOCAL3, LOG_LOCAL4, LOG_LOCAL5, LOG_LOCAL6, LOG_LOCAL7.

       --log-priority=STRING
              Specify the log priority to use. Defaults to  LOG_ERR.  Legal  inputs  are  LOG_EMERG,  LOG_ALERT,
              LOG_CRIT, LOG_ERR, LOG_WARNING, LOG_NOTICE, LOG_INFO, LOG_DEBUG.

       --cache-directory=DIRECTORY
              Specify  an  alternate  cache  directory location for ipmiseld to use. The cache directory will be
              used to cache a wide variety of data, including the SDR and recent logging information  to  ensure
              log entries are not missed on reboots and other system failures.

       --ignore-sdr
              Ignore  SDR  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.

       --re-download-sdr
              Re-download the SDR on start even if it is not out of date. This may help work around systems that
              do not properly timestamp SDR modification times.

       --clear-sel
              On startup, clear any SEL being monitored. May be useful the first time running ipmiseld to  avoid
              warning messages or SEL clears until a long time in the future.

       --threadpool-count=NUM
              Specify  the  number  of  threads  for  parallel  SEL  polling. This option is very similar to the
              --fanout option in ipmi-sel(8) but the threads are created only once on initialization for  faster
              processing.  Defaults to 8, however the threadpool count will always be decreased if the number of
              nodes specified is less than the number of threads.

       --test-run
              Do not daemonize, output the current SEL of configured hosts as a test  of  current  settings  and
              configuration. SEL entries will be output to stdout instead of syslog.

       --foreground
              Run daemon in the foreground. SEL entries will be output to stdout instead of syslog.

SEL LOG FORMAT STRING

       The    output    format    of   log   messages   can   be   adjusted   via   the   --system-event-format,
       --oem-timestamped-event-format  and   --oem-non-timestamped-event-format   options.   Options   such   as
       --interpret-oem-data,  --entity-sensor-names,  and  --non-abbreviated-units can further adjust the output
       format. The following conversion directives will allow the user to output specifics  of  each  SEL  event
       that occurs.

       For System, OEM timestamped, and OEM non-timestamped events

       %h - target host, useful if logging from multiple hosts

       %i - record ID in decimal

       %I - event state interpretation (NOMINAL, WARNING, or CRITICAL)

       For System and OEM timestamped events

       %t - time in format H:M:S using 24 hour clock

       %d - date in format D-M-YEAR

       For System events

       %T - sensor type

       %s - sensor name

       %e - event data 1 string

       %f - event data 2 string [2]

       %h - event data 3 string

       %c - combined event data 2 and event data 3 string

       %p - event data 2 previous state string

       %S - event data 2 severity string

       %E - combined event data 1, 2, and 3 string

       %k - event direction

       For OEM timestamped events

       %m - manufacturer id

       For OEM timestamped and OEM non-timestamped events

       %o - oem data in hex

       %O - OEM supplied string describing the event (depends on manufacturer)

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.

       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.

IPMISELD 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.

       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.

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.
