SYNOPSIS

9       ipmi-sel [OPTION...]
10

DESCRIPTION

12       Ipmi-sel is used to view and manage System Event Log (SEL) entries. SEL
13       records store system event information and may be useful for  debugging
14       problems.   Ipmi-sel  does  not inform the user if an event is particu‐
15       larly good or bad, just that the event occurred. Users may wish to  use
16       the --output-event-state option to output the analyzed state.
17
18       Listed  below  are general IPMI options, tool specific options, trouble
19       shooting information, workaround information, examples, and  known  is‐
20       sues.  For  a  general introduction to FreeIPMI please see freeipmi(7).
21       To perform some advanced SEL management, please see bmc-device(8).
22

GENERAL OPTIONS

24       The following options are general options for configuring IPMI communi‐
25       cation and executing general tool commands.
26
27       -D IPMIDRIVER, --driver-type=IPMIDRIVER
28              Specify  the  driver type to use instead of doing an auto selec‐
29              tion.  The currently available outofband  drivers  are  LAN  and
30              LAN_2_0,  which  perform IPMI 1.5 and IPMI 2.0 respectively. The
31              currently available inband  drivers  are  KCS,  SSIF,  OPENIPMI,
32              SUNBMC, and INTELDCMI.
33
34       --disable-auto-probe
35              Do not probe in-band IPMI devices for default settings.
36
37       --driver-address=DRIVER-ADDRESS
38              Specify  the  in-band  driver  address to be used instead of the
39              probed value. DRIVER-ADDRESS should be prefixed with "0x" for  a
40              hex value and '0' for an octal value.
41
42       --driver-device=DEVICE
43              Specify the in-band driver device path to be used instead of the
44              probed path.
45
46       --register-spacing=REGISTER-SPACING
47              Specify the in-band  driver  register  spacing  instead  of  the
48              probed  value. Argument is in bytes (i.e. 32bit register spacing
49              = 4)
50
51       --target-channel-number=CHANNEL-NUMBER
52              Specify the in-band driver target channel number  to  send  IPMI
53              requests to.
54
55       --target-slave-address=SLAVE-ADDRESS
56              Specify  the in-band driver target slave number to send IPMI re‐
57              quests to.
58
59       -h      IPMIHOST1,IPMIHOST2,...,      --hostname=IPMIHOST1[:PORT],IPMI‐
60       HOST2[:PORT],...
61              Specify  the  remote host(s) to communicate with. Multiple host‐
62              names may be separated by comma or may be specified in  a  range
63              format;  see  HOSTRANGED  SUPPORT below. An optional port can be
64              specified with each host, which may be useful in port forwarding
65              or  similar situations.  If specifying an IPv6 address and port,
66              use the format [ADDRESS]:PORT.
67
68       -u USERNAME, --username=USERNAME
69              Specify the username to use when authenticating with the  remote
70              host.  If not specified, a null (i.e. anonymous) username is as‐
71              sumed. The user must have atleast USER privileges in  order  for
72              this tool to operate fully.
73
74       -p PASSWORD, --password=PASSWORD
75              Specify the password to use when authenticationg with the remote
76              host.  If not specified, a null  password  is  assumed.  Maximum
77              password length is 16 for IPMI 1.5 and 20 for IPMI 2.0.
78
79       -P, --password-prompt
80              Prompt  for  password  to  avoid  possibility  of  listing it in
81              process lists.
82
83       -k K_G, --k-g=K_G
84              Specify the K_g BMC key to use when authenticating with the  re‐
85              mote host for IPMI 2.0. If not specified, a null key is assumed.
86              To input the key in hexadecimal form,  prefix  the  string  with
87              '0x'.  E.g.,  the  key  'abc' can be entered with the either the
88              string 'abc' or the string '0x616263'
89
90       -K, --k-g-prompt
91              Prompt for k-g to avoid possibility of  listing  it  in  process
92              lists.
93
94       --session-timeout=MILLISECONDS
95              Specify  the  session timeout in milliseconds. Defaults to 20000
96              milliseconds (20 seconds) if not specified.
97
98       --retransmission-timeout=MILLISECONDS
99              Specify the packet retransmission timeout in  milliseconds.  De‐
100              faults to 1000 milliseconds (1 second) if not specified. The re‐
101              transmission timeout cannot be larger than the session timeout.
102
103       -a AUTHENTICATION-TYPE, --authentication-type=AUTHENTICATION-TYPE
104              Specify the IPMI 1.5 authentication type to use.  The  currently
105              available  authentication types are NONE, STRAIGHT_PASSWORD_KEY,
106              MD2, and MD5. Defaults to MD5 if not specified.
107
108       -I CIPHER-SUITE-ID, --cipher-suite-id=CIPHER-SUITE-ID
109              Specify the IPMI 2.0 cipher suite ID to use. The Cipher Suite ID
110              identifies a set of authentication, integrity, and confidential‐
111              ity algorithms to use for IPMI 2.0 communication. The  authenti‐
112              cation  algorithm  identifies  the  algorithm to use for session
113              setup, the integrity algorithm identifies the algorithm  to  use
114              for session packet signatures, and the confidentiality algorithm
115              identifies the algorithm to use for payload encryption. Defaults
116              to  cipher  suite  ID  3  if not specified. The following cipher
117              suite ids are currently supported:
118
119              0 - Authentication Algorithm = None; Integrity Algorithm = None;
120              Confidentiality Algorithm = None
121

127
128              3  - Authentication Algorithm = HMAC-SHA1; Integrity Algorithm =
129              HMAC-SHA1-96; Confidentiality Algorithm = AES-CBC-128
130
131              6 - Authentication Algorithm = HMAC-MD5; Integrity  Algorithm  =
132              None; Confidentiality Algorithm = None
133
134              7  -  Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
135              HMAC-MD5-128; Confidentiality Algorithm = None
136
137              8 - Authentication Algorithm = HMAC-MD5; Integrity  Algorithm  =
138              HMAC-MD5-128; Confidentiality Algorithm = AES-CBC-128
139
140              11  - Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
141              MD5-128; Confidentiality Algorithm = None
142
143              12 - Authentication Algorithm = HMAC-MD5; Integrity Algorithm  =
144              MD5-128; Confidentiality Algorithm = AES-CBC-128
145
146              15 - Authentication Algorithm = HMAC-SHA256; Integrity Algorithm
147              = None; Confidentiality Algorithm = None
148
149              16 - Authentication Algorithm = HMAC-SHA256; Integrity Algorithm
150              = HMAC_SHA256_128; Confidentiality Algorithm = None
151
152              17 - Authentication Algorithm = HMAC-SHA256; Integrity Algorithm
153              = HMAC_SHA256_128; Confidentiality Algorithm = AES-CBC-128
154
155       -l PRIVILEGE-LEVEL, --privilege-level=PRIVILEGE-LEVEL
156              Specify the privilege level to be used. The currently  available
157              privilege  levels are USER, OPERATOR, and ADMIN. Defaults to OP‐
158              ERATOR if not specified.
159
160       --config-file=FILE
161              Specify an alternate configuration file.
162
163       -W WORKAROUNDS, --workaround-flags=WORKAROUNDS
164              Specify workarounds to vendor compliance issues. Multiple  work‐
165              arounds  can be specified separated by commas. A special command
166              line flag of "none", will indicate no workarounds (may be useful
167              for overriding configured defaults). See WORKAROUNDS below for a
168              list of available workarounds.
169
170       --debug
171              Turn on debugging.
172
173       -?, --help

175
176       --usage
177              Output a usage message and exit.
178
179       -V, --version
180              Output the program version and exit.
181

IPMI-SEL OPTIONS

183       The following options are specific to ipmi-sel.
184
185       -v     Output verbose output. This option will output event  direction.
186              Event  direction may be useful to differentiate severity between
187              some events. For example, some motherboards may issue  an  event
188              both  when  a  temperature  exceeds a threshold and when it goes
189              back down below it.
190
191       -vv    Output very verbose output. This option will  output  additional
192              information than verbose output. Most notably it will output ad‐
193              ditional hex codes to given information  on  ambiguous  SEL  en‐
194              tries,  such as OEM codes. For example, it will output Generator
195              ID hex codes for sensors without names, event type codes for OEM
196              events,  and  record types for OEM records. This information may
197              be useful if you are writing a parser outside of ipmi-sel to in‐
198              terpret OEM information.
199
200       -i, --info
201              Show general information about the SEL.
202
203       --display=RECORD-IDS-LIST
204              Display  SEL  records by record id. Accepts space or comma sepa‐
205              rated lists.
206
207       --exclude-display=RECORD-IDS-LIST
208              Exclude display of SEL records by record id.  Accepts  space  or
209              comma separated lists.
210
211       --display-range=START-END
212              Display SEL records from record id START to END.
213
214       --exclude-display-range=START-END
215              Exclude display of SEL records from record id START to END.
216
217       --date-range=DATE-DATE
218              Display  SEL records with events occurring in the specified date
219              range.  Dates may be specified in MM/DD/YYYY or MM-DD-YYYY  for‐
220              mat.  The month may be specified as a numeral or its abbreviated
221              string name. The current local system time can be specified with
222              "now".  Note  that non-timestamped records will not be displayed
223              automatically because they do not possess a timestamp.
224
225       --exclude-date-range=DATE-DATE
226              Exclude display of SEL records  with  events  occurring  in  the
227              specified  date  range.  Dates may be specified in MM/DD/YYYY or
228              MM-DD-YYYY format. The month may be specified as  a  numeral  or
229              its  abbreviated  string name. The current local system time can
230              be specified with "now". Note that non-timestamped records  will
231              be  displayed  automatically because they do not possess a time‐
232              stamp.
233
234       -t SENSOR-TYPE-LIST, --sensor-types=SENSOR-TYPE-LIST
235              Specify sensor types to show SEL events for. Multiple types  can
236              be separated by commas or spaces. A special command line type of
237              "all", will indicate all types should be shown  (may  be  useful
238              for  overriding  configured  defaults). Users may specify sensor
239              types by string (see --list-sensor-types  below)  or  by  number
240              (decimal or hex).
241
242       -T SENSOR-TYPE-LIST, --exclude-sensor-types=SENSOR-TYPE-LIST
243              Specify  sensor types to not show SEL events for. Multiple types
244              can be separated by commas or spaces.  A  special  command  line
245              type  of  "none", will indicate no types should be excluded (may
246              be useful for overriding configured defaults). Users may specify
247              sensor  types  by  string  (see --list-sensor-types below) or by
248              number (decimal or hex).
249
250       -L, --list-sensor-types
251              List sensor types.
252
253       --tail=count
254              Display approximately the last count SEL  records.  The  display
255              count  is calculated by approximating the record ids of the last
256              SEL records. It's correctness depends highly on the  SEL  imple‐
257              mentation by the vendor.
258
259       --clear
260              Clear SEL.
261
262       --post-clear
263              Identical  to --clear, except the SEL clearing will be performed
264              after SEL event records are displayed. This option is useful for
265              scripting if users intend to log SEL events to another log, then
266              immediately clear SEL. Unlike calling --clear in another  execu‐
267              tion  of  ipmi-sel, this option will use SEL reservations to no‐
268              tify the user if a SEL change has occurred while displaying  and
269              clearing  the  SEL.  This can protect users from a race, where a
270              new SEL event is unknowingly generated before clearing the  SEL.
271              Note that SEL reservations are optionally implemented by vendors
272              and may not be available on all machines.
273
274       --delete=RECORD-IDS-LIST
275              Delete records by record id in the SEL. Accepts space  or  comma
276              separated lists.
277
278       --delete-range=START-END
279              Delete record ids from START to END in the SEL.
280
281       --system-event-only
282              Output   only  system  event  records  (i.e.  don't  output  OEM
283              records).
284
285       --oem-event-only
286              Output only OEM event records (i.e. don't  output  system  event
287              records).
288
289       --output-manufacturer-id
290              For  OEM SEL record types, output the manufacturer ID along with
291              event data when available.
292
293       --output-event-state
294              Output event state in output. This will add an additional output
295              reporting  if  an event should be viewed as NOMINAL, WARNING, or
296              CRITICAL.  The event state is an interpreted value based on  the
297              configuration   file  /etc/freeipmi//freeipmi_interpret_sel.conf
298              and the event direction.  See freeipmi_interpret_sel.conf(5) for
299              more information.
300
301       --event-state-config-file=FILE
302              Specify  an alternate event state configuration file. Option ig‐
303              nored if --output-event-state not specified.
304
305       --hex-dump
306              Hex-dump SEL entries.
307
308       --interpret-oem-data
309              Attempt to interpret OEM data, such as event data, sensor  read‐
310              ings,  or  general  extra info, etc. If an OEM interpretation is
311              not available, the default output will be generated. Correctness
312              of  OEM  interpretations  cannot  be guaranteed due to potential
313              changes OEM vendors may make in products, firmware, etc. See OEM
314              INTERPRETATION  below for confirmed supported motherboard inter‐
315              pretations.
316
317       --output-oem-event-strings
318              Some motherboards support an IPMI OEM extension that returns the
319              string output for a system event. Such string output may be ben‐
320              eficial for determining the meaning behind OEM specific  events.
321              This option will use the OEM event string to describe all system
322              events in the ipmi-sel output. This option differs from --inter‐
323              pret-oem-data  option  in that all system events will output the
324              vendor supplied event string, not just events that are OEM  spe‐
325              cific.  The  event  string may be very different from the normal
326              FreeIPMI event string output. If an OEM  event  strings  is  not
327              available,  the  default  output will be output.  This option is
328              confirmed to work for Fujitsu iRMC S1 and iRMC S2 systems.
329
330       --entity-sensor-names
331              Output sensor names prefixed with their entity id  and  instance
332              number  when  appropriate. This may be necessary on some mother‐
333              boards to help identify what sensors are referencing. For  exam‐
334              ple,  a  motherboard may have multiple sensors named 'TEMP'. The
335              entity id and instance number  may  help  clarify  which  sensor
336              refers to "Processor 1" vs. "Processor 2".
337
338       --no-sensor-type-output
339              Do  not show sensor type output for each entry. On many systems,
340              the sensor type is redundant to the name of the sensor. This can
341              especially  be  true  if --entity-sensor-names is specified.  If
342              the sensor name is sufficient, or if the sensor type  is  of  no
343              interest  to  the user, this option can be specified to condense
344              output.
345
346       --comma-separated-output
347              Output fields in comma separated format.
348
349       --no-header-output
350              Do not output column headers. May be useful in scripting.
351
352       --non-abbreviated-units
353              Output non-abbreviated units (e.g. 'Amps' instead of  'A').  May
354              aid  in  disambiguation  of  units  (e.g.  'C'  for  Celsius  or
355              Coulombs).
356
357       --legacy-output
358              Output in legacy format. Newer options may not be applicable  to
359              legacy output.
360

SDR CACHE OPTIONS

362       This tool requires access to the sensor data repository (SDR) cache for
363       general operation. By default, SDR data will be downloaded  and  cached
364       on the local machine. The following options apply to the SDR cache.
365
366       --flush-cache
367              Flush  a  cached  version  of  the  sensor data repository (SDR)
368              cache. The SDR is typically cached for faster subsequent access.
369              However,  it  may need to be flushed and re-generated if the SDR
370              has been updated on a system.
371
372       --quiet-cache
373              Do not output information about cache creation/deletion. May  be
374              useful in scripting.
375
376       --sdr-cache-recreate
377              If the SDR cache is out of date or invalid, automatically recre‐
378              ate the sensor data repository (SDR) cache. This option  may  be
379              useful for scripting purposes.
380
381       --sdr-cache-file=FILE
382              Specify a specific sensor data repository (SDR) cache file to be
383              stored or read from. If this option is used when multiple  hosts
384              are  specified,  the  same  SDR  cache file will be used for all
385              hosts.
386
387       --sdr-cache-directory=DIRECTORY
388              Specify an alternate directory for sensor data repository  (SDR)
389              caches to be stored or read from. Defaults to the home directory
390              if not specified.
391
392       --ignore-sdr-cache
393              Ignore SDR cache related processing. May lead to  incomplete  or
394              less  useful  information  being  output,  however it will allow
395              functionality for systems without SDRs or when the  correct  SDR
396              cannot be loaded.
397

TIME OPTIONS

399       By  IPMI definition, all IPMI times and timestamps are stored in local‐
400       time. However, in many situations, the timestamps will not be stored in
401       localtime.  Whether  or not a system truly stored the timestamps in lo‐
402       caltime varies on many factors, such as the vendor, BIOS, and operating
403       system.  The following options will allow the user to adjust the inter‐
404       pretation of the stored timestamps and how they should be output.
405
406       --utc-to-localtime
407              Assume all times are reported in UTC time and convert  the  time
408              to localtime before being output.
409
410       --localtime-to-utc
411              Convert all localtime timestamps to UTC before being output.
412
413       --utc-offset=SECONDS
414              Specify  a  specific  UTC offset in seconds to be added to time‐
415              stamps.  Value can range from -86400 to 86400 seconds.  Defaults
416              to 0.
417

HOSTRANGED OPTIONS

419       The following options manipulate hostranged output. See HOSTRANGED SUP‐
420       PORT below for additional information on hostranges.
421
422       -B, --buffer-output
423              Buffer hostranged output. For each node, buffer standard  output
424              until the node has completed its IPMI operation. When specifying
425              this option, data may appear to output slower to the user  since
426              the  the entire IPMI operation must complete before any data can
427              be output.  See HOSTRANGED SUPPORT below for additional informa‐
428              tion.
429
430       -C, --consolidate-output
431              Consolidate hostranged output. The complete standard output from
432              every node specified will be consolidated  so  that  nodes  with
433              identical  output are not output twice. A header will list those
434              nodes with the consolidated output. When this option  is  speci‐
435              fied,  no  output  can  be seen until the IPMI operations to all
436              nodes has completed. If the  user  breaks  out  of  the  program
437              early,  all  currently  consolidated  output will be dumped. See
438              HOSTRANGED SUPPORT below for additional information.
439
440       -F NUM, --fanout=NUM
441              Specify multiple host fanout. A "sliding window" (or fanout) al‐
442              gorithm  is  used for parallel IPMI communication so that slower
443              nodes or timed out nodes will not impede parallel communication.
444              The maximum number of threads available at the same time is lim‐
445              ited by the fanout. The default is 64.
446
447       -E, --eliminate
448              Eliminate hosts determined as undetected  by  ipmidetect.   This
449              attempts to remove the common issue of hostranged execution tim‐
450              ing out due to several nodes being removed  from  service  in  a
451              large  cluster.  The  ipmidetectd  daemon must be running on the
452              node executing the command.
453
454       --always-prefix
455              Always prefix output, even if only one host is specified or com‐
456              municating  in-band. This option is primarily useful for script‐
457              ing purposes. Option will be ignored if specified  with  the  -C
458              option.
459

HOSTRANGED SUPPORT

461       Multiple hosts can be input either as an explicit comma separated lists
462       of hosts or a range of hostnames in  the  general  form:  prefix[n-m,l-
463       k,...],  where  n < m and l < k, etc. The later form should not be con‐
464       fused with regular expression character classes (also denoted  by  []).
465       For example, foo[19] does not represent foo1 or foo9, but rather repre‐
466       sents a degenerate range: foo19.
467
468       This range syntax is meant only as a convenience  on  clusters  with  a
469       prefixNN  naming  convention  and specification of ranges should not be
470       considered necessary -- the list foo1,foo9 could be specified as  such,
471       or by the range foo[1,9].
472
473       Some examples of range usage follow:
474           foo[01-05] instead of foo01,foo02,foo03,foo04,foo05
475           foo[7,9-10] instead of foo7,foo9,foo10
476           foo[0-3] instead of foo0,foo1,foo2,foo3
477
478       As a reminder to the reader, some shells will interpret brackets ([ and
479       ]) for pattern matching. Depending on your shell, it may  be  necessary
480       to enclose ranged lists within quotes.
481
482       When  multiple  hosts  are specified by the user, a thread will be exe‐
483       cuted for each host in parallel up to the configured fanout (which  can
484       be  adjusted via the -F option). This will allow communication to large
485       numbers of nodes far more quickly than if done in serial.
486
487       By default, standard output from each node  specified  will  be  output
488       with the hostname prepended to each line. Although this output is read‐
489       able in many situations, it may be difficult to read  in  other  situa‐
490       tions.  For  example, output from multiple nodes may be mixed together.
491       The -B and -C options can be used to change this default.
492
493       In-band IPMI Communication will be used when the  host  "localhost"  is
494       specified.  This  allows  the  user  to add the localhost into the hos‐
495       tranged output.
496

GENERAL TROUBLESHOOTING

498       Most often, IPMI problems are due to configuration problems.
499
500       IPMI over LAN problems involve a misconfiguration  of  the  remote  ma‐
501       chine's  BMC.   Double  check to make sure the following are configured
502       properly in the remote machine's BMC: IP address, MAC  address,  subnet
503       mask,  username,  user enablement, user privilege, password, LAN privi‐
504       lege, LAN enablement, and allowed authentication type(s). For IPMI  2.0
505       connections,  double  check  to make sure the cipher suite privilege(s)
506       and K_g key are configured properly. The  ipmi-config(8)  tool  can  be
507       used to check and/or change these configuration settings.
508
509       Inband  IPMI  problems  are  typically  caused by improperly configured
510       drivers or non-standard BMCs.
511
512       In addition to the troubleshooting tips below, please  see  WORKAROUNDS
513       below to also if there are any vendor specific bugs that have been dis‐
514       covered and worked around.
515
516       Listed below are many of the common issues for error messages.  For ad‐
517       ditional  support,  please  e-mail the <freeipmi-users@gnu.org> mailing
518       list.
519
520       "username invalid" - The username entered (or a NULL username  if  none
521       was  entered)  is  not  available on the remote machine. It may also be
522       possible the remote BMC's username configuration is incorrect.
523
524       "password invalid" - The password entered (or a NULL password  if  none
525       was  entered)  is not correct. It may also be possible the password for
526       the user is not correctly configured on the remote BMC.
527
528       "password verification timeout" - Password verification has timed  out.
529       A  "password  invalid"  error  (described  above) or a generic "session
530       timeout" (described below) occurred.  During this point in the protocol
531       it cannot be differentiated which occurred.
532
533       "k_g  invalid" - The K_g key entered (or a NULL K_g key if none was en‐
534       tered) is not correct. It may also be possible the K_g key is not  cor‐
535       rectly configured on the remote BMC.
536
537       "privilege level insufficient" - An IPMI command requires a higher user
538       privilege than the one authenticated with. Please try  to  authenticate
539       with a higher privilege. This may require authenticating to a different
540       user which has a higher maximum privilege.
541
542       "privilege level cannot be obtained for  this  user"  -  The  privilege
543       level  you are attempting to authenticate with is higher than the maxi‐
544       mum allowed for this user. Please try again with a lower privilege.  It
545       may  also be possible the maximum privilege level allowed for a user is
546       not configured properly on the remote BMC.
547
548       "authentication type unavailable for attempted privilege level"  -  The
549       authentication  type you wish to authenticate with is not available for
550       this privilege level. Please try again with an alternate authentication
551       type  or  alternate privilege level. It may also be possible the avail‐
552       able authentication types you can authenticate with are  not  correctly
553       configured on the remote BMC.
554
555       "cipher suite id unavailable" - The cipher suite id you wish to authen‐
556       ticate with is not available on the remote BMC. Please try  again  with
557       an alternate cipher suite id. It may also be possible the available ci‐
558       pher suite ids are not correctly configured on the remote BMC.
559
560       "ipmi 2.0 unavailable" - IPMI 2.0 was not discovered on the remote  ma‐
561       chine. Please try to use IPMI 1.5 instead.
562
563       "connection  timeout"  - Initial IPMI communication failed. A number of
564       potential errors are possible, including an invalid hostname specified,
565       an  IPMI  IP address cannot be resolved, IPMI is not enabled on the re‐
566       mote server, the network connection is bad, etc. Please verify configu‐
567       ration and connectivity.
568
569       "session  timeout"  - The IPMI session has timed out. Please reconnect.
570       If this error occurs often, you may wish to increase the retransmission
571       timeout. Some remote BMCs are considerably slower than others.
572
573       "device  not  found"  - The specified device could not be found. Please
574       check configuration or inputs and try again.
575
576       "driver timeout" - Communication with the driver or  device  has  timed
577       out. Please try again.
578
579       "message  timeout"  - Communication with the driver or device has timed
580       out. Please try again.
581
582       "BMC busy" - The BMC is currently busy. It may be  processing  informa‐
583       tion  or have too many simultaneous sessions to manage. Please wait and
584       try again.
585
586       "could not find inband device" - An inband device could not  be  found.
587       Please  check configuration or specify specific device or driver on the
588       command line.
589
590       "driver timeout" - The inband driver has timed out communicating to the
591       local  BMC  or  service  processor. The BMC or service processor may be
592       busy or (worst case) possibly non-functioning.
593
594       "internal IPMI error" - An IPMI error has occurred that  FreeIPMI  does
595       not  know  how to handle. Please e-mail <freeipmi-users@gnu.org> to re‐
596       port the issue.
597

IPMI-SEL TROUBLESHOOTING

599       Some timestamps in the SEL may report a date of 1-Jan-1970,  the  epoch
600       for  SEL  timestamps.  This  timestamp is not necessarily incorrect. It
601       usually indicates a hardware event that occurred before a timestamp  in
602       firmware has been initialized. For example, certain hardware components
603       will have their internal clocks reset during a power cycle.
604
605       However, if the internal clock of the SEL appears to be  regularly  in‐
606       correct,  you may need to set the SEL time. This can be done using bmc-
607       device(8).
608
609       The following are common SEL related messages.
610
611       "sel config file parse error" - A parse error  was  found  in  the  sel
612       event  interpretation  configuration  file.  Please see freeipmi_inter‐
613       pret_sel.conf(5).
614

WORKAROUNDS

616       With so many different vendors implementing their own  IPMI  solutions,
617       different  vendors  may implement their IPMI protocols incorrectly. The
618       following describes a number of workarounds currently available to han‐
619       dle  discovered compliance issues. When possible, workarounds have been
620       implemented so they will be transparent to the user. However, some will
621       require the user to specify a workaround be used via the -W option.
622
623       The hardware listed below may only indicate the hardware that a problem
624       was discovered on. Newer versions of hardware may fix the problems  in‐
625       dicated below. Similar machines from vendors may or may not exhibit the
626       same problems. Different vendors may license their  firmware  from  the
627       same  IPMI  firmware  developer,  so  it may be worthwhile to try work‐
628       arounds listed below even if your motherboard is not listed.
629
630       If you believe your hardware has an additional  compliance  issue  that
631       needs a workaround to be implemented, please contact the FreeIPMI main‐
632       tainers on <freeipmi-users@gnu.org> or <freeipmi-devel@gnu.org>.
633
634       assumeio - This workaround flag will assume inband interfaces  communi‐
635       cate  with  system  I/O rather than being memory-mapped. This will work
636       around systems that report invalid base addresses. Those  hitting  this
637       issue  may see "device not supported" or "could not find inband device"
638       errors.  Issue observed on HP ProLiant DL145 G1.
639
640       spinpoll - This workaround flag will inform some inband  drivers  (most
641       notably  the  KCS driver) to spin while polling rather than putting the
642       process to sleep. This may significantly improve the wall clock running
643       time  of  tools because an operating system scheduler's granularity may
644       be much larger than the time it takes to perform a single IPMI  message
645       transaction.  However,  by spinning, your system may be performing less
646       useful work by not contexting out the tool for a more useful task.
647
648       authcap - This workaround flag will skip early checks for username  ca‐
649       pabilities, authentication capabilities, and K_g support and allow IPMI
650       authentication to succeed. It works around multiple issues in which the
651       remote system does not properly report username capabilities, authenti‐
652       cation capabilities, or K_g status. Those hitting this  issue  may  see
653       "username  invalid",  "authentication  type  unavailable  for attempted
654       privilege level", or "k_g invalid"  errors.   Issue  observed  on  Asus
655       P5M2/P5MT-R/RS162-E4/RX4,    Intel   SR1520ML/X38ML,   and   Sun   Fire
656       2200/4150/4450 with ELOM.
657
658       nochecksumcheck - This workaround flag will tell FreeIPMI to not  check
659       the  checksums  returned  from  IPMI command responses. It works around
660       systems that return invalid checksums due to implementation errors, but
661       the  packet  is otherwise valid. Users are cautioned on the use of this
662       option, as it removes validation of packet integrity  in  a  number  of
663       circumstances.  However,  it  is unlikely to be an issue in most situa‐
664       tions. Those hitting this issue may see "connection timeout",  "session
665       timeout",  or  "password verification timeout" errors. On IPMI 1.5 con‐
666       nections, the "noauthcodecheck" workaround may also needed  too.  Issue
667       observed  on  Supermicro  X9SCM-iiF, Supermicro X9DRi-F, and Supermicro
668       X9DRFR.
669
670       idzero - This workaround flag will allow empty session IDs  to  be  ac‐
671       cepted  by  the client. It works around IPMI sessions that report empty
672       session IDs to the client. Those hitting this issue  may  see  "session
673       timeout" errors. Issue observed on Tyan S2882 with M3289 BMC.
674
675       unexpectedauth  -  This  workaround flag will allow unexpected non-null
676       authcodes to be checked as though they were expected. It  works  around
677       an  issue  when  packets contain non-null authentication data when they
678       should be null due to disabled per-message authentication.  Those  hit‐
679       ting  this  issue  may  see "session timeout" errors. Issue observed on
680       Dell PowerEdge 2850,SC1425. Confirmed fixed on newer firmware.
681
682       forcepermsg - This workaround flag will force  per-message  authentica‐
683       tion  to  be used no matter what is advertised by the remote system. It
684       works around an issue when per-message authentication is advertised  as
685       disabled on the remote system, but it is actually required for the pro‐
686       tocol. Those hitting this issue may see "session timeout" errors.   Is‐
687       sue observed on IBM eServer 325.
688
689       endianseq  -  This  workaround flag will flip the endian of the session
690       sequence numbers to allow the session to continue  properly.  It  works
691       around  IPMI  1.5  session  sequence numbers that are the wrong endian.
692       Those hitting this issue may see "session timeout"  errors.  Issue  ob‐
693       served on some Sun ILOM 1.0/2.0 (depends on service processor endian).
694
695       noauthcodecheck  - This workaround flag will tell FreeIPMI to not check
696       the authentication codes returned from IPMI 1.5 command  responses.  It
697       works  around  systems  that return invalid authentication codes due to
698       hashing or implementation errors. Users are cautioned  on  the  use  of
699       this option, as it removes an authentication check verifying the valid‐
700       ity of a packet. However, in most organizations, this is unlikely to be
701       a  security  issue.  Those hitting this issue may see "connection time‐
702       out", "session timeout", or  "password  verification  timeout"  errors.
703       Issue  observed  on  Xyratex FB-H8-SRAY, Intel Windmill, Quanta Winter‐
704       fell, and Wiwynn Windmill.
705
706       intel20 - This workaround flag will work around several Intel IPMI  2.0
707       authentication issues. The issues covered include padding of usernames,
708       and password  truncation  if  the  authentication  algorithm  is  HMAC-
709       MD5-128. Those hitting this issue may see "username invalid", "password
710       invalid", or "k_g invalid" errors. Issue observed  on  Intel  SE7520AF2
711       with Intel Server Management Module (Professional Edition).
712
713       supermicro20 - This workaround flag will work around several Supermicro
714       IPMI 2.0  authentication  issues  on  motherboards  w/  Peppercon  IPMI
715       firmware.  The issues covered include handling invalid length authenti‐
716       cation codes. Those hitting this issue may see "password  invalid"  er‐
717       rors.   Issue  observed  on  Supermicro H8QME with SIMSO daughter card.
718       Confirmed fixed on newerver firmware.
719
720       sun20 - This workaround flag will work work around several Sun IPMI 2.0
721       authentication issues. The issues covered include invalid lengthed hash
722       keys, improperly hashed keys, and invalid cipher suite  records.  Those
723       hitting  this  issue  may see "password invalid" or "bmc error" errors.
724       Issue observed on Sun Fire 4100/4200/4500 with ILOM.   This  workaround
725       automatically includes the "opensesspriv" workaround.
726
727       opensesspriv - This workaround flag will slightly alter FreeIPMI's IPMI
728       2.0 connection protocol to workaround an invalid hashing algorithm used
729       by  the remote system. The privilege level sent during the Open Session
730       stage of an IPMI 2.0 connection is used for hashing keys instead of the
731       privilege  level  sent during the RAKP1 connection stage. Those hitting
732       this issue may see "password invalid", "k_g invalid", or "bad  rmcpplus
733       status  code"  errors.   Issue observed on Sun Fire 4100/4200/4500 with
734       ILOM, Inventec 5441/Dell Xanadu II, Supermicro X8DTH, Supermicro X8DTG,
735       Intel  S5500WBV/Penguin  Relion  700,  Intel S2600JF/Appro 512X, Quanta
736       QSSC-S4R/Appro GB812X-CN, and Dell C5220. This workaround is  automati‐
737       cally triggered with the "sun20" workaround.
738
739       integritycheckvalue  - This workaround flag will work around an invalid
740       integrity check value during an IPMI 2.0 session establishment when us‐
741       ing  Cipher  Suite  ID 0. The integrity check value should be 0 length,
742       however the remote motherboard responds with a non-empty  field.  Those
743       hitting  this issue may see "k_g invalid" errors. Issue observed on Su‐
744       permicro X8DTG, Supermicro X8DTU,  and  Intel  S5500WBV/Penguin  Relion
745       700, and Intel S2600JF/Appro 512X.
746
747       assumemaxsdrrecordcount  -  This  workaround will inform SDR reading to
748       stop reading after a known maximum number  of  SDR  records  have  been
749       read. This will work around systems that have mis-implemented SDR read‐
750       ing functions. Those hitting this issue may see "SDR record  count  in‐
751       valid" errors. Issue observed on unspecified Inspur motherboard.
752
753       assumesystemevent  -  This  workaround  option  will assume invalid SEL
754       record types are system event records. Records may  be  formatted  cor‐
755       rectly  but  report  invalid record types. Those hitting this issue may
756       see "Unknown SEL Record Type" errors. Output may be unknown,  pray  for
757       the best. This option is confirmed to work around compliances issues on
758       HP DL 380 G5 motherboards.
759
760       No IPMI 1.5 Support - Some motherboards that support IPMI 2.0 have been
761       found  to  not support IPMI 1.5. Those hitting this issue may see "ipmi
762       2.0 unavailable" or "connection timeout"  errors.  This  issue  can  be
763       worked  around  by  using  IPMI  2.0  instead of IPMI 1.5 by specifying
764       --driver-type=LAN_2_0. Issue observed on a number of HP and  Supermicro
765       motherboards.
766

OEM INTERPRETATION

768       The  following  motherboards are confirmed to have atleast some support
769       by the --interpret-oem-data option. While highly probable the OEM  data
770       interpretations  would work across other motherboards by the same manu‐
771       facturer, there are no guarantees. Some of the motherboards  below  may
772       be rebranded by vendors/distributors.

DIAGNOSTICS

817       Upon successful execution, exit status is 0. On error, exit  status  is
818       1.
819
820       If multiple hosts are specified for communication, the exit status is 0
821       if and only if all targets successfully  execute.  Otherwise  the  exit
822       status is 1.
823

KNOWN ISSUES

825       On  older  operating systems, if you input your username, password, and
826       other potentially security relevant information on  the  command  line,
827       this information may be discovered by other users when using tools like
828       the ps(1) command or looking in the /proc file system. It is  generally
829       more  secure  to input password information with options like the -P or
830       -K options. Configuring security relevant information in  the  FreeIPMI
831       configuration file would also be an appropriate way to hide this infor‐
832       mation.
833
834       In order to prevent brute force attacks,  some  BMCs  will  temporarily
835       "lock  up" after a number of remote authentication errors. You may need
836       to wait awhile in order to this temporary "lock up" to pass before  you
837       may authenticate again.
