GENERAL OPTIONS

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

136              7  -  Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
137              HMAC-MD5-128; Confidentiality Algorithm = None
138
139              8 - Authentication Algorithm = HMAC-MD5; Integrity  Algorithm  =
140              HMAC-MD5-128; Confidentiality Algorithm = AES-CBC-128
141
142              11  - Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
143              MD5-128; Confidentiality Algorithm = None
144

149              = None; Confidentiality Algorithm = None
150
151              16 - Authentication Algorithm = HMAC-SHA256; Integrity Algorithm
152              = HMAC_SHA256_128; Confidentiality Algorithm = None
153
154              17 - Authentication Algorithm = HMAC-SHA256; Integrity Algorithm
155              = HMAC_SHA256_128; Confidentiality Algorithm = AES-CBC-128
156
157       -l PRIVILEGE-LEVEL, --privilege-level=PRIVILEGE-LEVEL
158              Specify the privilege level to be used. The currently  available
159              privilege  levels  are  USER,  OPERATOR,  and ADMIN. Defaults to
160              ADMIN if not specified.
161
162       --config-file=FILE
163              Specify an alternate configuration file.
164
165       -W WORKAROUNDS, --workaround-flags=WORKAROUNDS
166              Specify workarounds to vendor compliance issues. Multiple  work‐
167              arounds  can be specified separated by commas. A special command
168              line flag of "none", will indicate no workarounds (may be useful
169              for overriding configured defaults). See WORKAROUNDS below for a
170              list of available workarounds.

183

IPMI-CHASSIS OPTIONS

185       The following options are specific to ipmi-chassis.
186
187       --get-chassis-capabilities
188              Get chassis capabilities. This command  returns  information  on
189              which main chassis management functions are available.
190
191       --get-chassis-status
192              Get  chassis  status.  This  command  returns  high level status
193              information on the chassis.
194
195       --chassis-control=CONTROL
196              Control the chassis. This command provides power-up, power-down,
197              and  reset  control.  Supported  values:  POWER-DOWN,  POWER-UP,
198              POWER-CYCLE, HARD-RESET, DIAGNOSTIC-INTERRUPT, SOFT-SHUTDOWN.
199
200       --chassis-identify=IDENTIFY
201              Set chassis identification. This command controls physical  sys‐
202              tem  identification, typically a LED. Supported values: TURN-OFF
203              to turn off identification, <interval> to turn on identification
204              for "interval" seconds, FORCE to turn on indefinitely.
205
206       --get-system-restart-cause
207              Get system restart cause.
208
209       --get-power-on-hours-counter
210              Get power on hours (POH) counter.
211

HOSTRANGED OPTIONS

213       The following options manipulate hostranged output. See HOSTRANGED SUP‐
214       PORT below for additional information on hostranges.
215
216       -B, --buffer-output
217              Buffer hostranged output. For each node, buffer standard  output
218              until the node has completed its IPMI operation. When specifying
219              this option, data may appear to output slower to the user  since
220              the  the entire IPMI operation must complete before any data can
221              be output.  See HOSTRANGED SUPPORT below for additional informa‐
222              tion.
223
224       -C, --consolidate-output
225              Consolidate hostranged output. The complete standard output from
226              every node specified will be consolidated  so  that  nodes  with
227              identical  output are not output twice. A header will list those
228              nodes with the consolidated output. When this option  is  speci‐
229              fied,  no  output  can  be seen until the IPMI operations to all
230              nodes has completed. If the  user  breaks  out  of  the  program
231              early,  all  currently  consolidated  output will be dumped. See
232              HOSTRANGED SUPPORT below for additional information.
233
234       -F NUM, --fanout=NUM
235              Specify multiple host fanout. A  "sliding  window"  (or  fanout)
236              algorithm is used for parallel IPMI communication so that slower
237              nodes or timed out nodes will not impede parallel communication.
238              The maximum number of threads available at the same time is lim‐
239              ited by the fanout. The default is 64.
240
241       -E, --eliminate
242              Eliminate hosts determined as undetected  by  ipmidetect.   This
243              attempts to remove the common issue of hostranged execution tim‐
244              ing out due to several nodes being removed  from  service  in  a
245              large  cluster.  The  ipmidetectd  daemon must be running on the
246              node executing the command.
247
248       --always-prefix
249              Always prefix output, even if only one host is specified or com‐
250              municating  in-band. This option is primarily useful for script‐
251              ing purposes. Option will be ignored if specified  with  the  -C
252              option.
253

HOSTRANGED SUPPORT

255       Multiple hosts can be input either as an explicit comma separated lists
256       of hosts or a range of hostnames in  the  general  form:  prefix[n-m,l-
257       k,...],  where  n < m and l < k, etc. The later form should not be con‐
258       fused with regular expression character classes (also denoted  by  []).
259       For example, foo[19] does not represent foo1 or foo9, but rather repre‐
260       sents a degenerate range: foo19.
261
262       This range syntax is meant only as a convenience  on  clusters  with  a
263       prefixNN  naming  convention  and specification of ranges should not be
264       considered necessary -- the list foo1,foo9 could be specified as  such,
265       or by the range foo[1,9].
266
267       Some examples of range usage follow:
268           foo[01-05] instead of foo01,foo02,foo03,foo04,foo05
269           foo[7,9-10] instead of foo7,foo9,foo10
270           foo[0-3] instead of foo0,foo1,foo2,foo3
271
272       As a reminder to the reader, some shells will interpret brackets ([ and
273       ]) for pattern matching. Depending on your shell, it may  be  necessary
274       to enclose ranged lists within quotes.
275
276       When  multiple  hosts  are specified by the user, a thread will be exe‐
277       cuted for each host in parallel up to the configured fanout (which  can
278       be  adjusted via the -F option). This will allow communication to large
279       numbers of nodes far more quickly than if done in serial.
280
281       By default, standard output from each node  specified  will  be  output
282       with the hostname prepended to each line. Although this output is read‐
283       able in many situations, it may be difficult to read  in  other  situa‐
284       tions.  For  example, output from multiple nodes may be mixed together.
285       The -B and -C options can be used to change this default.
286
287       In-band IPMI Communication will be used when the  host  "localhost"  is
288       specified.  This  allows  the  user  to add the localhost into the hos‐
289       tranged output.
290

GENERAL TROUBLESHOOTING

292       Most often, IPMI problems are due to configuration problems.
293
294       IPMI over  LAN  problems  involve  a  misconfiguration  of  the  remote
295       machine's  BMC.  Double check to make sure the following are configured
296       properly in the remote machine's BMC: IP address, MAC  address,  subnet
297       mask,  username,  user enablement, user privilege, password, LAN privi‐
298       lege, LAN enablement, and allowed authentication type(s). For IPMI  2.0
299       connections,  double  check  to make sure the cipher suite privilege(s)
300       and K_g key are configured properly. The  ipmi-config(8)  tool  can  be
301       used to check and/or change these configuration settings.
302
303       Inband  IPMI  problems  are  typically  caused by improperly configured
304       drivers or non-standard BMCs.
305
306       In addition to the troubleshooting tips below, please  see  WORKAROUNDS
307       below to also if there are any vendor specific bugs that have been dis‐
308       covered and worked around.
309
310       Listed below are many of the common issues  for  error  messages.   For
311       additional  support, please e-mail the <freeipmi-users@gnu.org> mailing
312       list.
313
314       "username invalid" - The username entered (or a NULL username  if  none
315       was  entered)  is  not  available on the remote machine. It may also be
316       possible the remote BMC's username configuration is incorrect.
317
318       "password invalid" - The password entered (or a NULL password  if  none
319       was  entered)  is not correct. It may also be possible the password for
320       the user is not correctly configured on the remote BMC.
321
322       "password verification timeout" - Password verification has timed  out.
323       A  "password  invalid"  error  (described  above) or a generic "session
324       timeout" (described below) occurred.  During this point in the protocol
325       it cannot be differentiated which occurred.
326
327       "k_g  invalid"  -  The  K_g  key entered (or a NULL K_g key if none was
328       entered) is not correct. It may also be possible the  K_g  key  is  not
329       correctly configured on the remote BMC.
330
331       "privilege level insufficient" - An IPMI command requires a higher user
332       privilege than the one authenticated with. Please try  to  authenticate
333       with a higher privilege. This may require authenticating to a different
334       user which has a higher maximum privilege.
335
336       "privilege level cannot be obtained for  this  user"  -  The  privilege
337       level  you are attempting to authenticate with is higher than the maxi‐
338       mum allowed for this user. Please try again with a lower privilege.  It
339       may  also be possible the maximum privilege level allowed for a user is
340       not configured properly on the remote BMC.
341
342       "authentication type unavailable for attempted privilege level"  -  The
343       authentication  type you wish to authenticate with is not available for
344       this privilege level. Please try again with an alternate authentication
345       type  or  alternate privilege level. It may also be possible the avail‐
346       able authentication types you can authenticate with are  not  correctly
347       configured on the remote BMC.
348
349       "cipher suite id unavailable" - The cipher suite id you wish to authen‐
350       ticate with is not available on the remote BMC. Please try  again  with
351       an  alternate  cipher  suite  id. It may also be possible the available
352       cipher suite ids are not correctly configured on the remote BMC.
353
354       "ipmi 2.0 unavailable" - IPMI 2.0 was  not  discovered  on  the  remote
355       machine. Please try to use IPMI 1.5 instead.
356
357       "connection  timeout"  - Initial IPMI communication failed. A number of
358       potential errors are possible, including an invalid hostname specified,
359       an  IPMI  IP  address  cannot  be  resolved, IPMI is not enabled on the
360       remote server, the network connection is bad, etc. Please  verify  con‐
361       figuration and connectivity.
362
363       "session  timeout"  - The IPMI session has timed out. Please reconnect.
364       If this error occurs often, you may wish to increase the retransmission
365       timeout. Some remote BMCs are considerably slower than others.
366
367       "device  not  found"  - The specified device could not be found. Please
368       check configuration or inputs and try again.
369
370       "driver timeout" - Communication with the driver or  device  has  timed
371       out. Please try again.
372
373       "message  timeout"  - Communication with the driver or device has timed
374       out. Please try again.
375
376       "BMC busy" - The BMC is currently busy. It may be  processing  informa‐
377       tion  or have too many simultaneous sessions to manage. Please wait and
378       try again.
379
380       "could not find inband device" - An inband device could not  be  found.
381       Please  check configuration or specify specific device or driver on the
382       command line.
383
384       "driver timeout" - The inband driver has timed out communicating to the
385       local  BMC  or  service  processor. The BMC or service processor may be
386       busy or (worst case) possibly non-functioning.
387
388       "internal IPMI error" - An IPMI error has occurred that  FreeIPMI  does
389       not  know  how  to  handle.  Please  e-mail <freeipmi-users@gnu.org> to
390       report the issue.
391

WORKAROUNDS

393       With so many different vendors implementing their own  IPMI  solutions,
394       different  vendors  may implement their IPMI protocols incorrectly. The
395       following describes a number of workarounds currently available to han‐
396       dle  discovered compliance issues. When possible, workarounds have been
397       implemented so they will be transparent to the user. However, some will
398       require the user to specify a workaround be used via the -W option.
399
400       The hardware listed below may only indicate the hardware that a problem
401       was discovered on. Newer versions of  hardware  may  fix  the  problems
402       indicated  below.  Similar machines from vendors may or may not exhibit
403       the same problems. Different vendors may license  their  firmware  from
404       the  same IPMI firmware developer, so it may be worthwhile to try work‐
405       arounds listed below even if your motherboard is not listed.
406
407       If you believe your hardware has an additional  compliance  issue  that
408       needs a workaround to be implemented, please contact the FreeIPMI main‐
409       tainers on <freeipmi-users@gnu.org> or <freeipmi-devel@gnu.org>.
410
411       assumeio - This workaround flag will assume inband interfaces  communi‐
412       cate  with  system  I/O rather than being memory-mapped. This will work
413       around systems that report invalid base addresses. Those  hitting  this
414       issue  may see "device not supported" or "could not find inband device"
415       errors.  Issue observed on HP ProLiant DL145 G1.
416
417       spinpoll - This workaround flag will inform some inband  drivers  (most
418       notably  the  KCS driver) to spin while polling rather than putting the
419       process to sleep. This may significantly improve the wall clock running
420       time  of  tools because an operating system scheduler's granularity may
421       be much larger than the time it takes to perform a single IPMI  message
422       transaction.  However,  by spinning, your system may be performing less
423       useful work by not contexting out the tool for a more useful task.
424
425       authcap - This workaround flag will  skip  early  checks  for  username
426       capabilities,  authentication  capabilities,  and K_g support and allow
427       IPMI authentication to succeed. It  works  around  multiple  issues  in
428       which the remote system does not properly report username capabilities,
429       authentication capabilities, or K_g status. Those  hitting  this  issue
430       may  see  "username  invalid",  "authentication  type  unavailable  for
431       attempted privilege level", or "k_g invalid" errors.  Issue observed on
432       Asus  P5M2/P5MT-R/RS162-E4/RX4,  Intel  SR1520ML/X38ML,  and  Sun  Fire
433       2200/4150/4450 with ELOM.
434
435       nochecksumcheck - This workaround flag will tell FreeIPMI to not  check
436       the  checksums  returned  from  IPMI command responses. It works around
437       systems that return invalid checksums due to implementation errors, but
438       the  packet  is otherwise valid. Users are cautioned on the use of this
439       option, as it removes validation of packet integrity  in  a  number  of
440       circumstances.  However,  it  is unlikely to be an issue in most situa‐
441       tions. Those hitting this issue may see "connection timeout",  "session
442       timeout",  or  "password verification timeout" errors. On IPMI 1.5 con‐
443       nections, the "noauthcodecheck" workaround may also needed  too.  Issue
444       observed  on  Supermicro  X9SCM-iiF, Supermicro X9DRi-F, and Supermicro
445       X9DRFR.
446
447       idzero - This workaround flag  will  allow  empty  session  IDs  to  be
448       accepted by the client. It works around IPMI sessions that report empty
449       session IDs to the client. Those hitting this issue  may  see  "session
450       timeout" errors. Issue observed on Tyan S2882 with M3289 BMC.
451
452       unexpectedauth  -  This  workaround flag will allow unexpected non-null
453       authcodes to be checked as though they were expected. It  works  around
454       an  issue  when  packets contain non-null authentication data when they
455       should be null due to disabled per-message authentication.  Those  hit‐
456       ting  this  issue  may  see "session timeout" errors. Issue observed on
457       Dell PowerEdge 2850,SC1425. Confirmed fixed on newer firmware.
458
459       forcepermsg - This workaround flag will force  per-message  authentica‐
460       tion  to  be used no matter what is advertised by the remote system. It
461       works around an issue when per-message authentication is advertised  as
462       disabled on the remote system, but it is actually required for the pro‐
463       tocol. Those hitting this  issue  may  see  "session  timeout"  errors.
464       Issue observed on IBM eServer 325.
465
466       endianseq  -  This  workaround flag will flip the endian of the session
467       sequence numbers to allow the session to continue  properly.  It  works
468       around  IPMI  1.5  session  sequence numbers that are the wrong endian.
469       Those hitting this  issue  may  see  "session  timeout"  errors.  Issue
470       observed  on  some  Sun  ILOM  1.0/2.0  (depends  on  service processor
471       endian).
472
473       noauthcodecheck - This workaround flag will tell FreeIPMI to not  check
474       the  authentication  codes returned from IPMI 1.5 command responses. It
475       works around systems that return invalid authentication  codes  due  to
476       hashing  or  implementation  errors.  Users are cautioned on the use of
477       this option, as it removes an authentication check verifying the valid‐
478       ity of a packet. However, in most organizations, this is unlikely to be
479       a security issue. Those hitting this issue may  see  "connection  time‐
480       out",  "session  timeout",  or  "password verification timeout" errors.
481       Issue observed on Xyratex FB-H8-SRAY, Intel  Windmill,  Quanta  Winter‐
482       fell, and Wiwynn Windmill.
483
484       intel20  - This workaround flag will work around several Intel IPMI 2.0
485       authentication issues. The issues covered include padding of usernames,
486       and  password  truncation  if  the  authentication  algorithm  is HMAC-
487       MD5-128. Those hitting this issue may see "username invalid", "password
488       invalid",  or  "k_g  invalid" errors. Issue observed on Intel SE7520AF2
489       with Intel Server Management Module (Professional Edition).
490
491       supermicro20 - This workaround flag will work around several Supermicro
492       IPMI  2.0  authentication  issues  on  motherboards  w/  Peppercon IPMI
493       firmware. The issues covered include handling invalid length  authenti‐
494       cation  codes.  Those  hitting  this  issue  may see "password invalid"
495       errors.  Issue observed on Supermicro H8QME with SIMSO  daughter  card.
496       Confirmed fixed on newerver firmware.
497
498       sun20 - This workaround flag will work work around several Sun IPMI 2.0
499       authentication issues. The issues covered include invalid lengthed hash
500       keys,  improperly  hashed keys, and invalid cipher suite records. Those
501       hitting this issue may see "password invalid" or  "bmc  error"  errors.
502       Issue  observed  on Sun Fire 4100/4200/4500 with ILOM.  This workaround
503       automatically includes the "opensesspriv" workaround.
504
505       opensesspriv - This workaround flag will slightly alter FreeIPMI's IPMI
506       2.0 connection protocol to workaround an invalid hashing algorithm used
507       by the remote system. The privilege level sent during the Open  Session
508       stage of an IPMI 2.0 connection is used for hashing keys instead of the
509       privilege level sent during the RAKP1 connection stage.  Those  hitting
510       this  issue may see "password invalid", "k_g invalid", or "bad rmcpplus
511       status code" errors.  Issue observed on Sun  Fire  4100/4200/4500  with
512       ILOM, Inventec 5441/Dell Xanadu II, Supermicro X8DTH, Supermicro X8DTG,
513       Intel S5500WBV/Penguin Relion 700, Intel S2600JF/Appro 512X, and Quanta
514       QSSC-S4R/Appro  GB812X-CN.  This  workaround is automatically triggered
515       with the "sun20" workaround.
516
517       integritycheckvalue - This workaround flag will work around an  invalid
518       integrity  check  value  during  an IPMI 2.0 session establishment when
519       using Cipher Suite ID 0. The integrity check value should be 0  length,
520       however  the  remote motherboard responds with a non-empty field. Those
521       hitting this issue may see "k_g  invalid"  errors.  Issue  observed  on
522       Supermicro  X8DTG,  Supermicro X8DTU, and Intel S5500WBV/Penguin Relion
523       700, and Intel S2600JF/Appro 512X.
524
525       No IPMI 1.5 Support - Some motherboards that support IPMI 2.0 have been
526       found  to  not support IPMI 1.5. Those hitting this issue may see "ipmi
527       2.0 unavailable" or "connection timeout"  errors.  This  issue  can  be
528       worked  around  by  using  IPMI  2.0  instead of IPMI 1.5 by specifying
529       --driver-type=LAN_2_0. Issue observed on HP Proliant DL 145.

DIAGNOSTICS

551       Upon successful execution, exit status is 0. On error, exit  status  is
552       1.
553
554       If multiple hosts are specified for communication, the exit status is 0
555       if and only if all targets successfully  execute.  Otherwise  the  exit
556       status is 1.
557

KNOWN ISSUES

559       On  older  operating systems, if you input your username, password, and
560       other potentially security relevant information on  the  command  line,
561       this information may be discovered by other users when using tools like
562       the ps(1) command or looking in the /proc file system. It is  generally
563       more  secure  to input password information with options like the -P or
564       -K options. Configuring security relevant information in  the  FreeIPMI
565       configuration file would also be an appropriate way to hide this infor‐
566       mation.
567
568       In order to prevent brute force attacks,  some  BMCs  will  temporarily
569       "lock  up" after a number of remote authentication errors. You may need
570       to wait awhile in order to this temporary "lock up" to pass before  you
571       may authenticate again.
