6 ipmi-config - configure IPMI values
7
9 ipmi-config [OPTION...]
10
12 ipmi-config is used to get and set configuration parameters in IPMI. In
13 can be used to configured usernames, passwords, networking information,
14 security, Serial-over-LAN (SOL), Platform Event Filtering (PEF), boot
15 devices, power restoration policy, sensor thresholds, sensor events,
16 and many more configuration options. Some configuration is typically
17 required before most IPMI tools can be used to access a machine
18 remotely. By default, ipmi-config, will let you --checkout or --commit
19 only the core IPMI values necessary for IPMI configuration. For addi‐
20 tional advanced configuration fields related to Chassis configuration
21 (including boot options), Platform Event Filtering (PEF), or Sensors,
22 see the --category option below. The majority of configuration opera‐
23 tions require ADMIN privilege when using ipmi-config out-of-band.
24 Although connecting via a user with ADMIN privileges is not required
25 for out-of-band use, the vast majority of configuration options will
26 not be retrieved or set.
27 Listed below are general IPMI options, tool specific options, trouble
29 shooting information, workaround information, examples, and known
30 issues. For a general introduction to FreeIPMI please see freeipmi(7).
31 See GENERAL USE below for a description on basic use of ipmi-config.
32
34 The following options are general options for configuring IPMI communi‐
35 cation and executing general tool commands.
36 -D IPMIDRIVER, --driver-type=IPMIDRIVER
38 Specify the driver type to use instead of doing an auto selec‐
39 tion. The currently available outofband drivers are LAN and
40 LAN_2_0, which perform IPMI 1.5 and IPMI 2.0 respectively. The
41 currently available inband drivers are KCS, SSIF, OPENIPMI,
42 SUNBMC, and INTELDCMI.
43 --disable-auto-probe
45 Do not probe in-band IPMI devices for default settings.
46 --driver-address=DRIVER-ADDRESS
48 Specify the in-band driver address to be used instead of the
49 probed value. DRIVER-ADDRESS should be prefixed with "0x" for a
50 hex value and '0' for an octal value.
51 --driver-device=DEVICE
53 Specify the in-band driver device path to be used instead of the
54 probed path.
55 --register-spacing=REGISTER-SPACING
57 Specify the in-band driver register spacing instead of the
58 probed value. Argument is in bytes (i.e. 32bit register spacing
59 = 4)
60 --target-channel-number=CHANNEL-NUMBER
62 Specify the in-band driver target channel number to send IPMI
63 requests to.
64 --target-slave-address=SLAVE-ADDRESS
66 Specify the in-band driver target slave number to send IPMI
67 requests to.
68 -h IPMIHOST1,IPMIHOST2,..., --hostname=IPMIHOST1[:PORT],IPMI‐
70 HOST2[:PORT],...
71 Specify the remote host(s) to communicate with. Multiple host‐
72 names may be separated by comma or may be specified in a range
73 format; see HOSTRANGED SUPPORT below. An optional port can be
74 specified with each host, which may be useful in port forwarding
75 or similar situations. If specifying an IPv6 address and port,
76 use the format [ADDRESS]:PORT.
77 -u USERNAME, --username=USERNAME
79 Specify the username to use when authenticating with the remote
80 host. If not specified, a null (i.e. anonymous) username is
81 assumed. The user must have atleast ADMIN privileges in order
82 for this tool to operate fully.
83 -p PASSWORD, --password=PASSWORD
85 Specify the password to use when authenticationg with the remote
86 host. If not specified, a null password is assumed. Maximum
87 password length is 16 for IPMI 1.5 and 20 for IPMI 2.0.
88 -P, --password-prompt
90 Prompt for password to avoid possibility of listing it in
91 process lists.
92 -k K_G, --k-g=K_G
94 Specify the K_g BMC key to use when authenticating with the
95 remote host for IPMI 2.0. If not specified, a null key is
96 assumed. To input the key in hexadecimal form, prefix the string
97 with '0x'. E.g., the key 'abc' can be entered with the either
98 the string 'abc' or the string '0x616263'
99 -K, --k-g-prompt
101 Prompt for k-g to avoid possibility of listing it in process
102 lists.
103 --session-timeout=MILLISECONDS
105 Specify the session timeout in milliseconds. Defaults to 20000
106 milliseconds (20 seconds) if not specified.
107 --retransmission-timeout=MILLISECONDS
109 Specify the packet retransmission timeout in milliseconds.
110 Defaults to 1000 milliseconds (1 second) if not specified. The
111 retransmission timeout cannot be larger than the session time‐
112 out.
113 -a AUTHENTICATION-TYPE, --authentication-type=AUTHENTICATION-TYPE
115 Specify the IPMI 1.5 authentication type to use. The currently
116 available authentication types are NONE, STRAIGHT_PASSWORD_KEY,
117 MD2, and MD5. Defaults to MD5 if not specified.
118 -I CIPHER-SUITE-ID, --cipher-suite-id=CIPHER-SUITE-ID
120 Specify the IPMI 2.0 cipher suite ID to use. The Cipher Suite ID
121 identifies a set of authentication, integrity, and confidential‐
122 ity algorithms to use for IPMI 2.0 communication. The authenti‐
123 cation algorithm identifies the algorithm to use for session
124 setup, the integrity algorithm identifies the algorithm to use
125 for session packet signatures, and the confidentiality algorithm
126 identifies the algorithm to use for payload encryption. Defaults
127 to cipher suite ID 3 if not specified. The following cipher
128 suite ids are currently supported:
129 0 - Authentication Algorithm = None; Integrity Algorithm = None;
131 Confidentiality Algorithm = None
132 1 - Authentication Algorithm = HMAC-SHA1; Integrity Algorithm =
134 None; Confidentiality Algorithm = None
135 2 - Authentication Algorithm = HMAC-SHA1; Integrity Algorithm =
137 HMAC-SHA1-96; Confidentiality Algorithm = None
138 3 - Authentication Algorithm = HMAC-SHA1; Integrity Algorithm =
140 HMAC-SHA1-96; Confidentiality Algorithm = AES-CBC-128
141 6 - Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
143 None; Confidentiality Algorithm = None
144 7 - Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
146 HMAC-MD5-128; Confidentiality Algorithm = None
147 8 - Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
149 HMAC-MD5-128; Confidentiality Algorithm = AES-CBC-128
150 11 - Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
152 MD5-128; Confidentiality Algorithm = None
153 12 - Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
155 MD5-128; Confidentiality Algorithm = AES-CBC-128
156 15 - Authentication Algorithm = HMAC-SHA256; Integrity Algorithm
158 = None; Confidentiality Algorithm = None
159 16 - Authentication Algorithm = HMAC-SHA256; Integrity Algorithm
161 = HMAC_SHA256_128; Confidentiality Algorithm = None
162 17 - Authentication Algorithm = HMAC-SHA256; Integrity Algorithm
164 = HMAC_SHA256_128; Confidentiality Algorithm = AES-CBC-128
165 -l PRIVILEGE-LEVEL, --privilege-level=PRIVILEGE-LEVEL
167 Specify the privilege level to be used. The currently available
168 privilege levels are USER, OPERATOR, and ADMIN. Defaults to
169 ADMIN if not specified.
170 --config-file=FILE
172 Specify an alternate configuration file.
173 -W WORKAROUNDS, --workaround-flags=WORKAROUNDS
175 Specify workarounds to vendor compliance issues. Multiple work‐
176 arounds can be specified separated by commas. A special command
177 line flag of "none", will indicate no workarounds (may be useful
178 for overriding configured defaults). See WORKAROUNDS below for a
179 list of available workarounds.
180 --debug
182 Turn on debugging.
183 -?, --help
185 Output a help list and exit.
186 --usage
188 Output a usage message and exit.
189 -V, --version
191 Output the program version and exit.
192
194 The following options are used to read, write, and find differences in
195 configuration values.
196 -g CATEGORY, --category=CATEGORY
198 Specify the category or categories of configuration data to con‐
199 figure. Currently available choices: core, chassis, sensors,
200 pef, dcmi. Multiple categories can be separated by comma. core
201 includes all major IPMI configuration necessary to get IPMI to
202 function on a sytem, such as configuration for users, passwords,
203 authentication, networking, and serial-over-lan (SOL). chassis
204 includes all chassis relevant configuration including boot
205 options, front panel buttons, and power behavior. dcmi includes
206 specialized functions provided by the Data Center Management
207 Interface (DCMI). Defaults to core if not specified.
208 -o, --checkout
210 Fetch configuration information.
211 -c, --commit
213 Update configuration information from a config file or key
214 pairs.
215 -d, --diff
217 Show differences between stored information and a config file or
218 key pairs.
219 -n FILENAME, --filename=FILENAME
221 Specify a config file for checkout/commit/diff. If specified
222 with checkout, cannot use with multiple hosts or with
223 --always-prefix.
224 -e "KEY=VALUE", --key-pair="KEY=VALUE"
226 Specify KEY=VALUE pairs for checkout/commit/diff. Specify KEY by
227 SectionName:FieldName. This option can be used multiple times.
228 On commit, any KEY=VALUE pairs will overwrite any pairs speci‐
229 fied in a file with --filename.
230 -S SECTION, --section=SECTION
232 Specify a SECTION for checkout. This option can be used multiple
233 times. The SECTION you are specifying must be within the cate‐
234 gory or categories specified with --category.
235 -L, --listsections
237 List available sections for checkout with respect to the cate‐
238 gory or categories under --category. Some sections in the list
239 may not be checked out by default and may require verbosity to
240 be increased.
241 -v, --verbose
243 Output verbose information. When used with --checkout, addi‐
244 tional uncommon sections and/or fields will be shown. In the
245 core category, this includes checking out Serial Configuration
246 parameters, Vlan parameters, IPv4 Header parameters, RMCP port,
247 and sections for each channel on a system, if multiple channels
248 exist. In the pef category, this includes checkout out sections
249 for each channel on a system, if multiple channels exist.
250 -vv Output very verbose information. Output additional detailed
252 information about what fields can and cannot be checked out, and
253 sometimes the reason why. Sometimes output fields that are iden‐
254 tified as unsupported on the motherboard.
255 --lan-channel-number=NUMBER
257 Use an specific channel number for LAN configuration. Particu‐
258 larly useful if motherboard contains multiple LAN channels and a
259 user wishes to use a specific one.
260 --serial-channel-number=NUMBER
262 Use an specific channel number for serial configuration. Partic‐
263 ularly useful if motherboard contains multiple serial channels
264 and a user wishes to use a specific one.
265 --sol-channel-number=NUMBER
267 Use an specific channel number for SOL configuration. Particu‐
268 larly useful if motherboard contains multiple SOL channels and a
269 user wishes to use a specific one.
270
272 This tool requires access to the sensor data repository (SDR) cache for
273 general operation. By default, SDR data will be downloaded and cached
274 on the local machine. The following options apply to the SDR cache.
275 --flush-cache
277 Flush a cached version of the sensor data repository (SDR)
278 cache. The SDR is typically cached for faster subsequent access.
279 However, it may need to be flushed and re-generated if the SDR
280 has been updated on a system.
281 --quiet-cache
283 Do not output information about cache creation/deletion. May be
284 useful in scripting.
285 --sdr-cache-recreate
287 If the SDR cache is out of date or invalid, automatically recre‐
288 ate the sensor data repository (SDR) cache. This option may be
289 useful for scripting purposes.
290 --sdr-cache-file=FILE
292 Specify a specific sensor data repository (SDR) cache file to be
293 stored or read from. If this option is used when multiple hosts
294 are specified, the same SDR cache file will be used for all
295 hosts.
296 --sdr-cache-directory=DIRECTORY
298 Specify an alternate directory for sensor data repository (SDR)
299 caches to be stored or read from. Defaults to the home directory
300 if not specified.
301
303 The following options manipulate hostranged output. See HOSTRANGED SUP‐
304 PORT below for additional information on hostranges.
305 -B, --buffer-output
307 Buffer hostranged output. For each node, buffer standard output
308 until the node has completed its IPMI operation. When specifying
309 this option, data may appear to output slower to the user since
310 the the entire IPMI operation must complete before any data can
311 be output. See HOSTRANGED SUPPORT below for additional informa‐
312 tion.
313 -C, --consolidate-output
315 Consolidate hostranged output. The complete standard output from
316 every node specified will be consolidated so that nodes with
317 identical output are not output twice. A header will list those
318 nodes with the consolidated output. When this option is speci‐
319 fied, no output can be seen until the IPMI operations to all
320 nodes has completed. If the user breaks out of the program
321 early, all currently consolidated output will be dumped. See
322 HOSTRANGED SUPPORT below for additional information.
323 -F NUM, --fanout=NUM
325 Specify multiple host fanout. A "sliding window" (or fanout)
326 algorithm is used for parallel IPMI communication so that slower
327 nodes or timed out nodes will not impede parallel communication.
328 The maximum number of threads available at the same time is lim‐
329 ited by the fanout. The default is 64.
330 -E, --eliminate
332 Eliminate hosts determined as undetected by ipmidetect. This
333 attempts to remove the common issue of hostranged execution tim‐
334 ing out due to several nodes being removed from service in a
335 large cluster. The ipmidetectd daemon must be running on the
336 node executing the command.
337 --always-prefix
339 Always prefix output, even if only one host is specified or com‐
340 municating in-band. This option is primarily useful for script‐
341 ing purposes. Option will be ignored if specified with the -C
342 option.
343
345 Most users of will want to:
346 A) Run with --checkout to get a copy of the current configuration and
348 store it in a file. The standard output can be redirected to a file or
349 a file can be specified with the --filename option.
350 B) Edit the configuration file with an editor.
352 C) Commit the configuration back using the --commit option and specify‐
354 ing the configuration file with the --filename option. The configura‐
355 tion can be committed to multiple hosts in parallel via the hostrange
356 support.
357 Although not typically necessarily, some motherboards do not store con‐
359 figuration values in non-volatile memory. Therefore, after system
360 reboots, some configuration values may have changed. The user may wish
361 to run configuration tools on each boot to ensure configuration values
362 remain.
363 Comments will be listed on occassion in checked out files with informa‐
365 tion on how to configure fields. The ipmi-config.conf(5) manpage also
366 provides additional information on the meaning of different fields.
367 For users with large clusters or sets of nodes, you may wish to use the
369 same configuration file for all nodes. The one problem with this is
370 that the IP address and MAC address will be different on each node in
371 your cluster and thus can't be configured through the same config file.
372 The IP address and MAC address in your config file may be overwritten
373 on the command line using --key-pair option. The following example
374 could be used in a script to configure each node in a cluster with the
375 same BMC config file. The script only needs to determine the correct IP
376 address and MAC address to use.
377 # ipmi-config --commit -k Lan_Conf:Ip_Address=$MY_IP -k
379 Lan_Conf:Mac_Address=$MY_MAC --filename=my_bmc.conf
380
382 The UserN:Password fields (where N is a number) cannot be checked out
383 on some systems, therefore the checked out value will always be blank.
384 The UserN:Enable_User field (where N is a number) cannot be checked out
386 on older IPMI systems, therefore the checked out value will sometime be
387 blank.
388 The UserN:Lan_Session_Limit and UserN:Serial_Session_Limit fields
390 (where N is a number) cannot be checked out on some systems, therefore
391 the checked out value will always be blank. If not specified in later
392 commits of configurations, the field may be reset to 0 due to a
393 requirement that other fields (configured along with the session limit)
394 will require an input value for the session limit. Under most condi‐
395 tions, it is not necessary to set this field and most users may choose
396 to ignore it. This field is considered optional by IPMI standards, and
397 may result in errors when attempting to configure it to a non-zero
398 value. If errors to occur, setting the value back to 0 should resolve
399 problems.
400 The fields Lan_Conf:IP_Address and Lan_Conf:MAC_Address cannot be com‐
402 mitted in parallel via hostrange support. Each machine must be config‐
403 ured with a unique IP Address and MAC Address tuple, therefore we dis‐
404 allow this configuration in ipmi-config.
405 On some motherboards, Lan_Conf:MAC_Address may be read only and the MAC
407 address is automatically configured.
408 On some motherboards, Lan_Conf:MAC_Address may be read only and the MAC
410 address is configured via an OEM command. See ipmi-oem(8) to see if OEM
411 configuration for your motherboard is supported.
412 On some motherboards, a number of user configuration fields cannot be
414 read or configured until after a non-null username or non-null password
415 is configured. In some of these cases, an appropriate output in the
416 config file will indicate this situation. However, not all motherboard
417 corner cases may be detected. Users may wish to play around with the
418 ordering of fields to work around these problems.
419 On some motherboards, OEM Authentication in Lan_Conf_Auth cannot be
421 enabled. However, the default motherboard settings have these fields
422 enabled. Users are advised to disable all OEM Authentication in this
423 section.
424 On some motherboards, multiple channels may exist for either LAN or
426 Serial IPMI communication. If multiple channels exist, configuration of
427 both channels can be viewed and ultimately configured by running
428 --checkout under verbose mode. Each section or key name will be suf‐
429 fixed appropriately with the word Channel and the channel number. For
430 example, you might see a Lan_Conf_Channel_1 and Lan_Conf_Channel_3,
431 where you can configure LAN configuration on Channels 1 and 3 respec‐
432 tively.
433 On some motherboards, configuration changes will not be "absorbed" by
435 the system until the motherboard is hard-reset. This can be accom‐
436 plished by physically powering off and on the system (e.g. button
437 push), or it can be accomplished through a cold-reset. A cold-reset can
438 be executed via bmc-device.
439
441 The Chassis_Front_Panel_Buttons:Enable_Standby_Button_For_Enter‐
442 ing_Standy, Chassis_Front_Panel_Buttons:Enable_Diagnostic_Inter‐
443 rupt_Button Chassis_Front_Panel_Buttons:Enable_Reset_Button, and Chas‐
444 sis_Front_Panel_Buttons:Enable_Power_Off_Button_For_Power_Off_Only
445 fields may not be able to be checked out on some IPMI systems, there‐
446 fore the checked out value may be blank. Some of these fields may be
447 disableable, while some are not. The Chassis_Power_Conf:Power_Con‐
448 trol_Interval field cannot be checked out. Therefore the checked out
449 value will always be blank.
450
452 On some motherboards, multiple channels may exist for LAN IPMI communi‐
453 cation. If multiple channels exist, configuration of both channels can
454 be viewed and ultimately configured by running --checkout under verbose
455 mode. Each section name will be suffixed appropriately with the word
456 Channel and the channel number. For example, you might see a Commu‐
457 nity_String_Channel_1 and Community_String_Channel_3, where you can
458 configure the Community String on Channels 1 and 3 respectively. The
459 following are the options suitable for input for Sensor_Type in PEF
460 configuration.
461 Sensor_Type Options
463 Reserved, Temperature, Voltage, Current, Fan, Physical_Security,
464 Platform_Security_Violation_Attempt, Processor, Power_Supply,
465 Power_Unit, Cooling_Device, Other_Units_Based_Sensor, Memory,
466 Drive_Slot, Post_Memory_Resize, System_Firmware_Progress,
467 Event_Logging_Disabled, Watchdog1, System_Event, Critical_Inter‐
468 rupt, Button_Switch, Module_Board, Microcontroller_Coprocessor,
469 Add_In_Card, Chassis, Chip_Set, Other_FRU, Cable_Interconnect,
470 Terminator, System_Boot_Initiated, Boot_Error, OS_Boot, OS_Crit‐
471 ical_Stop, Slot_Connector, System_ACPI_Power_State, Watchdog2,
472 Platform_Alert, Entity_Presence, Monitor_Asic_IC, Lan, Manage‐
473 ment_Subsystem_Health, Battery, Session_Audit, Version_Change,
474 FRU_State, and Any
475
477 Since many configurable fields involve decimal numbers, preci‐
478 sion/floating point inaccuracies may occur when configuring new thresh‐
479 olds. The inaccuracies may not be apparent immediately. It is recommend
480 users verify their changes after configuring new thresholds.
481
483 Multiple hosts can be input either as an explicit comma separated lists
484 of hosts or a range of hostnames in the general form: prefix[n-m,l-
485 k,...], where n < m and l < k, etc. The later form should not be con‐
486 fused with regular expression character classes (also denoted by []).
487 For example, foo[19] does not represent foo1 or foo9, but rather repre‐
488 sents a degenerate range: foo19.
489 This range syntax is meant only as a convenience on clusters with a
491 prefixNN naming convention and specification of ranges should not be
492 considered necessary -- the list foo1,foo9 could be specified as such,
493 or by the range foo[1,9].
494 Some examples of range usage follow:
496 foo[01-05] instead of foo01,foo02,foo03,foo04,foo05
497 foo[7,9-10] instead of foo7,foo9,foo10
498 foo[0-3] instead of foo0,foo1,foo2,foo3
499 As a reminder to the reader, some shells will interpret brackets ([ and
501 ]) for pattern matching. Depending on your shell, it may be necessary
502 to enclose ranged lists within quotes.
503 When multiple hosts are specified by the user, a thread will be exe‐
505 cuted for each host in parallel up to the configured fanout (which can
506 be adjusted via the -F option). This will allow communication to large
507 numbers of nodes far more quickly than if done in serial.
508 By default, standard output from each node specified will be output
510 with the hostname prepended to each line. Although this output is read‐
511 able in many situations, it may be difficult to read in other situa‐
512 tions. For example, output from multiple nodes may be mixed together.
513 The -B and -C options can be used to change this default.
514 In-band IPMI Communication will be used when the host "localhost" is
516 specified. This allows the user to add the localhost into the hos‐
517 tranged output.
518
520 Most often, IPMI problems are due to configuration problems.
521 IPMI over LAN problems involve a misconfiguration of the remote
523 machine's BMC. Double check to make sure the following are configured
524 properly in the remote machine's BMC: IP address, MAC address, subnet
525 mask, username, user enablement, user privilege, password, LAN privi‐
526 lege, LAN enablement, and allowed authentication type(s). For IPMI 2.0
527 connections, double check to make sure the cipher suite privilege(s)
528 and K_g key are configured properly. The ipmi-config(8) tool can be
529 used to check and/or change these configuration settings.
530 Inband IPMI problems are typically caused by improperly configured
532 drivers or non-standard BMCs.
533 In addition to the troubleshooting tips below, please see WORKAROUNDS
535 below to also if there are any vendor specific bugs that have been dis‐
536 covered and worked around.
537 Listed below are many of the common issues for error messages. For
539 additional support, please e-mail the <freeipmi-users@gnu.org> mailing
540 list.
541 "username invalid" - The username entered (or a NULL username if none
543 was entered) is not available on the remote machine. It may also be
544 possible the remote BMC's username configuration is incorrect.
545 "password invalid" - The password entered (or a NULL password if none
547 was entered) is not correct. It may also be possible the password for
548 the user is not correctly configured on the remote BMC.
549 "password verification timeout" - Password verification has timed out.
551 A "password invalid" error (described above) or a generic "session
552 timeout" (described below) occurred. During this point in the protocol
553 it cannot be differentiated which occurred.
554 "k_g invalid" - The K_g key entered (or a NULL K_g key if none was
556 entered) is not correct. It may also be possible the K_g key is not
557 correctly configured on the remote BMC.
558 "privilege level insufficient" - An IPMI command requires a higher user
560 privilege than the one authenticated with. Please try to authenticate
561 with a higher privilege. This may require authenticating to a different
562 user which has a higher maximum privilege.
563 "privilege level cannot be obtained for this user" - The privilege
565 level you are attempting to authenticate with is higher than the maxi‐
566 mum allowed for this user. Please try again with a lower privilege. It
567 may also be possible the maximum privilege level allowed for a user is
568 not configured properly on the remote BMC.
569 "authentication type unavailable for attempted privilege level" - The
571 authentication type you wish to authenticate with is not available for
572 this privilege level. Please try again with an alternate authentication
573 type or alternate privilege level. It may also be possible the avail‐
574 able authentication types you can authenticate with are not correctly
575 configured on the remote BMC.
576 "cipher suite id unavailable" - The cipher suite id you wish to authen‐
578 ticate with is not available on the remote BMC. Please try again with
579 an alternate cipher suite id. It may also be possible the available
580 cipher suite ids are not correctly configured on the remote BMC.
581 "ipmi 2.0 unavailable" - IPMI 2.0 was not discovered on the remote
583 machine. Please try to use IPMI 1.5 instead.
584 "connection timeout" - Initial IPMI communication failed. A number of
586 potential errors are possible, including an invalid hostname specified,
587 an IPMI IP address cannot be resolved, IPMI is not enabled on the
588 remote server, the network connection is bad, etc. Please verify con‐
589 figuration and connectivity.
590 "session timeout" - The IPMI session has timed out. Please reconnect.
592 If this error occurs often, you may wish to increase the retransmission
593 timeout. Some remote BMCs are considerably slower than others.
594 "device not found" - The specified device could not be found. Please
596 check configuration or inputs and try again.
597 "driver timeout" - Communication with the driver or device has timed
599 out. Please try again.
600 "message timeout" - Communication with the driver or device has timed
602 out. Please try again.
603 "BMC busy" - The BMC is currently busy. It may be processing informa‐
605 tion or have too many simultaneous sessions to manage. Please wait and
606 try again.
607 "could not find inband device" - An inband device could not be found.
609 Please check configuration or specify specific device or driver on the
610 command line.
611 "driver timeout" - The inband driver has timed out communicating to the
613 local BMC or service processor. The BMC or service processor may be
614 busy or (worst case) possibly non-functioning.

617 With so many different vendors implementing their own IPMI solutions,
618 different vendors may implement their IPMI protocols incorrectly. The
619 following describes a number of workarounds currently available to han‐
620 dle discovered compliance issues. When possible, workarounds have been
621 implemented so they will be transparent to the user. However, some will
622 require the user to specify a workaround be used via the -W option.
623 The hardware listed below may only indicate the hardware that a problem
625 was discovered on. Newer versions of hardware may fix the problems
626 indicated below. Similar machines from vendors may or may not exhibit
627 the same problems. Different vendors may license their firmware from
628 the same IPMI firmware developer, so it may be worthwhile to try work‐
629 arounds listed below even if your motherboard is not listed.
630 If you believe your hardware has an additional compliance issue that
632 needs a workaround to be implemented, please contact the FreeIPMI main‐
633 tainers on <freeipmi-users@gnu.org> or <freeipmi-devel@gnu.org>.
634 assumeio - This workaround flag will assume inband interfaces communi‐
636 cate with system I/O rather than being memory-mapped. This will work
637 around systems that report invalid base addresses. Those hitting this
638 issue may see "device not supported" or "could not find inband device"
639 errors. Issue observed on HP ProLiant DL145 G1.
640 spinpoll - This workaround flag will inform some inband drivers (most
642 notably the KCS driver) to spin while polling rather than putting the
643 process to sleep. This may significantly improve the wall clock running
644 time of tools because an operating system scheduler's granularity may
645 be much larger than the time it takes to perform a single IPMI message
646 transaction. However, by spinning, your system may be performing less
647 useful work by not contexting out the tool for a more useful task.
648 authcap - This workaround flag will skip early checks for username
650 capabilities, authentication capabilities, and K_g support and allow
651 IPMI authentication to succeed. It works around multiple issues in
652 which the remote system does not properly report username capabilities,
653 authentication capabilities, or K_g status. Those hitting this issue
654 may see "username invalid", "authentication type unavailable for
655 attempted privilege level", or "k_g invalid" errors. Issue observed on
656 Asus P5M2/P5MT-R/RS162-E4/RX4, Intel SR1520ML/X38ML, and Sun Fire
657 2200/4150/4450 with ELOM.
658 nochecksumcheck - This workaround flag will tell FreeIPMI to not check
660 the checksums returned from IPMI command responses. It works around
661 systems that return invalid checksums due to implementation errors, but
662 the packet is otherwise valid. Users are cautioned on the use of this
663 option, as it removes validation of packet integrity in a number of
664 circumstances. However, it is unlikely to be an issue in most situa‐
665 tions. Those hitting this issue may see "connection timeout", "session
666 timeout", or "password verification timeout" errors. On IPMI 1.5 con‐
667 nections, the "noauthcodecheck" workaround may also needed too. Issue
668 observed on Supermicro X9SCM-iiF, Supermicro X9DRi-F, and Supermicro
669 X9DRFR.
670 idzero - This workaround flag will allow empty session IDs to be
672 accepted by the client. It works around IPMI sessions that report empty
673 session IDs to the client. Those hitting this issue may see "session
674 timeout" errors. Issue observed on Tyan S2882 with M3289 BMC.
675 unexpectedauth - This workaround flag will allow unexpected non-null
677 authcodes to be checked as though they were expected. It works around
678 an issue when packets contain non-null authentication data when they
679 should be null due to disabled per-message authentication. Those hit‐
680 ting this issue may see "session timeout" errors. Issue observed on
681 Dell PowerEdge 2850,SC1425. Confirmed fixed on newer firmware.
682 forcepermsg - This workaround flag will force per-message authentica‐
684 tion to be used no matter what is advertised by the remote system. It
685 works around an issue when per-message authentication is advertised as
686 disabled on the remote system, but it is actually required for the pro‐
687 tocol. Those hitting this issue may see "session timeout" errors.
688 Issue observed on IBM eServer 325.
689 endianseq - This workaround flag will flip the endian of the session
691 sequence numbers to allow the session to continue properly. It works
692 around IPMI 1.5 session sequence numbers that are the wrong endian.
693 Those hitting this issue may see "session timeout" errors. Issue
694 observed on some Sun ILOM 1.0/2.0 (depends on service processor
695 endian).
696 noauthcodecheck - This workaround flag will tell FreeIPMI to not check
698 the authentication codes returned from IPMI 1.5 command responses. It
699 works around systems that return invalid authentication codes due to
700 hashing or implementation errors. Users are cautioned on the use of
701 this option, as it removes an authentication check verifying the valid‐
702 ity of a packet. However, in most organizations, this is unlikely to be
703 a security issue. Those hitting this issue may see "connection time‐
704 out", "session timeout", or "password verification timeout" errors.
705 Issue observed on Xyratex FB-H8-SRAY, Intel Windmill, Quanta Winter‐
706 fell, and Wiwynn Windmill.
707 intel20 - This workaround flag will work around several Intel IPMI 2.0
709 authentication issues. The issues covered include padding of usernames,
710 and password truncation if the authentication algorithm is HMAC-
711 MD5-128. Those hitting this issue may see "username invalid", "password
712 invalid", or "k_g invalid" errors. Issue observed on Intel SE7520AF2
713 with Intel Server Management Module (Professional Edition).
714 supermicro20 - This workaround flag will work around several Supermicro
716 IPMI 2.0 authentication issues on motherboards w/ Peppercon IPMI
717 firmware. The issues covered include handling invalid length authenti‐
718 cation codes. Those hitting this issue may see "password invalid"
719 errors. Issue observed on Supermicro H8QME with SIMSO daughter card.
720 Confirmed fixed on newerver firmware.
721 sun20 - This workaround flag will work work around several Sun IPMI 2.0
723 authentication issues. The issues covered include invalid lengthed hash
724 keys, improperly hashed keys, and invalid cipher suite records. Those
725 hitting this issue may see "password invalid" or "bmc error" errors.
726 Issue observed on Sun Fire 4100/4200/4500 with ILOM. This workaround
727 automatically includes the "opensesspriv" workaround.
728 opensesspriv - This workaround flag will slightly alter FreeIPMI's IPMI
730 2.0 connection protocol to workaround an invalid hashing algorithm used
731 by the remote system. The privilege level sent during the Open Session
732 stage of an IPMI 2.0 connection is used for hashing keys instead of the
733 privilege level sent during the RAKP1 connection stage. Those hitting
734 this issue may see "password invalid", "k_g invalid", or "bad rmcpplus
735 status code" errors. Issue observed on Sun Fire 4100/4200/4500 with
736 ILOM, Inventec 5441/Dell Xanadu II, Supermicro X8DTH, Supermicro X8DTG,
737 Intel S5500WBV/Penguin Relion 700, Intel S2600JF/Appro 512X, and Quanta
738 QSSC-S4R/Appro GB812X-CN. This workaround is automatically triggered
739 with the "sun20" workaround.
740 integritycheckvalue - This workaround flag will work around an invalid
742 integrity check value during an IPMI 2.0 session establishment when
743 using Cipher Suite ID 0. The integrity check value should be 0 length,
744 however the remote motherboard responds with a non-empty field. Those
745 hitting this issue may see "k_g invalid" errors. Issue observed on
746 Supermicro X8DTG, Supermicro X8DTU, and Intel S5500WBV/Penguin Relion
747 700, and Intel S2600JF/Appro 512X.
748 No IPMI 1.5 Support - Some motherboards that support IPMI 2.0 have been
750 found to not support IPMI 1.5. Those hitting this issue may see "ipmi
751 2.0 unavailable" or "connection timeout" errors. This issue can be
752 worked around by using IPMI 2.0 instead of IPMI 1.5 by specifying
753 --driver-type=LAN_2_0. Issue observed on HP Proliant DL 145.
754 slowcommit - This workaround will slow down commits to the BMC by
756 sleeping one second between the commit of sections. It works around
757 motherboards that have BMCs that can be overwhelmed by commits. Those
758 hitting this issue may see commit errors or commits not being written
759 to the BMC. Issue observed on Supermicro H8QME.
760 veryslowcommit - This workaround will slow down commits to the BMC by
762 sleeping one second between the commit of every key. It works around
763 motherboards that have BMCs that can be overwhelmed by commits. Those
764 hitting this issue may see commit errors or commits not being written
765 to the BMC. Issue observed on Quanta S99Q/Dell FS12-TY.
766 solchannelassumelanchannel - This workaround will force ipmi-config to
768 assume that the channel used SOL is identical to the channel used for
769 LAN. On some motherboards, the SOL channel is reported incorrectly,
770 leading to incorrect configuration. Most notably, this problem has come
771 up when attempting to configure multiple channels. Issue observed on
772 Intel S5500WBV/Penguin Relion 700.

816 Upon successful execution, exit status is 0. On non-fatal error, exit
817 status is 1. On fatal error, exit status is 2.
818 If multiple hosts are specified for communication, the exit status is 0
820 if and only if all targets successfully execute. If any non-fatal error
821 occurs, exit status is 1. If any fatal error occurs, exit status is 2.
822
824 On older operating systems, if you input your username, password, and
825 other potentially security relevant information on the command line,
826 this information may be discovered by other users when using tools like
827 the ps(1) command or looking in the /proc file system. It is generally
828 more secure to input password information with options like the -P or
829 -K options. Configuring security relevant information in the FreeIPMI
830 configuration file would also be an appropriate way to hide this infor‐
831 mation.
832 In order to prevent brute force attacks, some BMCs will temporarily
834 "lock up" after a number of remote authentication errors. You may need
835 to wait awhile in order to this temporary "lock up" to pass before you
836 may authenticate again.
