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 separated 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",
       "bad rmcpplus status code", or "privilege level cannot be obtained for this user" 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, Dell C5220,
       and the OpenIPMI software BMC. This workaround is automatically triggered with the "sun20" workaround.

       integritycheckvalue  -  This  workaround flag will work around an invalid integrity check value during an
       IPMI 2.0 session establishment when 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 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  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.
