20 The following options are general options for configuring IPMI communi‐
21 cation and executing general tool commands.
22 -D IPMIDRIVER, --driver-type=IPMIDRIVER
24 Specify the driver type to use instead of doing an auto selec‐
25 tion. The currently available outofband drivers are LAN and
26 LAN_2_0, which perform IPMI 1.5 and IPMI 2.0 respectively. The
27 currently available inband drivers are KCS, SSIF, OPENIPMI,
28 SUNBMC, and INTELDCMI.
29 --disable-auto-probe
31 Do not probe in-band IPMI devices for default settings.
32 --driver-address=DRIVER-ADDRESS
34 Specify the in-band driver address to be used instead of the
35 probed value. DRIVER-ADDRESS should be prefixed with "0x" for a
36 hex value and '0' for an octal value.
37 --driver-device=DEVICE
39 Specify the in-band driver device path to be used instead of the
40 probed path.
41 --register-spacing=REGISTER-SPACING
43 Specify the in-band driver register spacing instead of the
44 probed value. Argument is in bytes (i.e. 32bit register spacing
45 = 4)
46 --target-channel-number=CHANNEL-NUMBER
48 Specify the in-band driver target channel number to send IPMI
49 requests to.
50 --target-slave-address=SLAVE-ADDRESS
52 Specify the in-band driver target slave number to send IPMI
53 requests to.
54 -h IPMIHOST1,IPMIHOST2,..., --hostname=IPMIHOST1[:PORT],IPMI‐
56 HOST2[:PORT],...
57 Specify the remote host(s) to communicate with. Multiple host‐
58 names may be separated by comma or may be specified in a range
59 format; see HOSTRANGED SUPPORT below. An optional port can be
60 specified with each host, which may be useful in port forwarding
61 or similar situations.
62 -u USERNAME, --username=USERNAME
64 Specify the username to use when authenticating with the remote
65 host. If not specified, a null (i.e. anonymous) username is
66 assumed. The user must have atleast USER privileges in order for
67 this tool to operate fully.
68 -p PASSWORD, --password=PASSWORD
70 Specify the password to use when authenticationg with the remote
71 host. If not specified, a null password is assumed. Maximum
72 password length is 16 for IPMI 1.5 and 20 for IPMI 2.0.
73 -P, --password-prompt
75 Prompt for password to avoid possibility of listing it in
76 process lists.
77 -k K_G, --k-g=K_G
79 Specify the K_g BMC key to use when authenticating with the
80 remote host for IPMI 2.0. If not specified, a null key is
81 assumed. To input the key in hexadecimal form, prefix the string
82 with '0x'. E.g., the key 'abc' can be entered with the either
83 the string 'abc' or the string '0x616263'
84 -K, --k-g-prompt
86 Prompt for k-g to avoid possibility of listing it in process
87 lists.
88 --session-timeout=MILLISECONDS
90 Specify the session timeout in milliseconds. Defaults to 20000
91 milliseconds (20 seconds) if not specified.
92 --retransmission-timeout=MILLISECONDS
94 Specify the packet retransmission timeout in milliseconds.
95 Defaults to 1000 milliseconds (1 second) if not specified. The
96 retransmission timeout cannot be larger than the session time‐
97 out.
98 -a AUTHENTICATION-TYPE, --authentication-type=AUTHENTICATION-TYPE
100 Specify the IPMI 1.5 authentication type to use. The currently
101 available authentication types are NONE, STRAIGHT_PASSWORD_KEY,
102 MD2, and MD5. Defaults to MD5 if not specified.
103 -I CIPHER-SUITE-ID, --cipher-suite-id=CIPHER-SUITE-ID
105 Specify the IPMI 2.0 cipher suite ID to use. The Cipher Suite ID
106 identifies a set of authentication, integrity, and confidential‐
107 ity algorithms to use for IPMI 2.0 communication. The authenti‐
108 cation algorithm identifies the algorithm to use for session
109 setup, the integrity algorithm identifies the algorithm to use
110 for session packet signatures, and the confidentiality algorithm
111 identifies the algorithm to use for payload encryption. Defaults
112 to cipher suite ID 3 if not specified. The following cipher
113 suite ids are currently supported:
114 0 - Authentication Algorithm = None; Integrity Algorithm = None;
116 Confidentiality Algorithm = None
117 1 - Authentication Algorithm = HMAC-SHA1; Integrity Algorithm =
119 None; Confidentiality Algorithm = None
120 2 - Authentication Algorithm = HMAC-SHA1; Integrity Algorithm =
122 HMAC-SHA1-96; Confidentiality Algorithm = None
123 3 - Authentication Algorithm = HMAC-SHA1; Integrity Algorithm =
125 HMAC-SHA1-96; Confidentiality Algorithm = AES-CBC-128
126 6 - Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
128 None; Confidentiality Algorithm = None
129 7 - Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
131 HMAC-MD5-128; Confidentiality Algorithm = None
132 8 - Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
134 HMAC-MD5-128; Confidentiality Algorithm = AES-CBC-128
135 11 - Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
137 MD5-128; Confidentiality Algorithm = None
138 12 - Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
140 MD5-128; Confidentiality Algorithm = AES-CBC-128
141 15 - Authentication Algorithm = HMAC-SHA256; Integrity Algorithm
143 = None; Confidentiality Algorithm = None
144 16 - Authentication Algorithm = HMAC-SHA256; Integrity Algorithm
146 = HMAC_SHA256_128; Confidentiality Algorithm = None
147 17 - Authentication Algorithm = HMAC-SHA256; Integrity Algorithm
149 = HMAC_SHA256_128; Confidentiality Algorithm = AES-CBC-128
150 -l PRIVILEGE-LEVEL, --privilege-level=PRIVILEGE-LEVEL
152 Specify the privilege level to be used. The currently available
153 privilege levels are USER, OPERATOR, and ADMIN. Defaults to USER
154 if not specified.
155 --config-file=FILE
157 Specify an alternate configuration file.
158 -W WORKAROUNDS, --workaround-flags=WORKAROUNDS
160 Specify workarounds to vendor compliance issues. Multiple work‐
161 arounds can be specified separated by commas. A special command
162 line flag of "none", will indicate no workarounds (may be useful
163 for overriding configured defaults). See WORKAROUNDS below for a
164 list of available workarounds.
165 --debug
167 Turn on debugging.
168 -?, --help
170 Output a help list and exit.
171 --usage
173 Output a usage message and exit.
174 -V, --version
176 Output the program version and exit.
177
179 The following options are specific to Bmc-info.
180 --get-device-id
182 Display only device ID information.
183 --get-device-guid
185 Display only device guid.
186 --get-system-guid
188 Display only system guid.
189 --get-system-info
191 Display only system info.
192 --get-channel-info
194 Display only channel information.
195 --interpret-oem-data
197 Attempt to interpret OEM data, such as event data, sensor read‐
198 ings, or general extra info, etc. If an OEM interpretation is
199 not available, the default output will be generated. Correctness
200 of OEM interpretations cannot be guaranteed due to potential
201 changes OEM vendors may make in products, firmware, etc. See OEM
202 INTERPRETATION below for confirmed supported motherboard inter‐
203 pretations.
204
206 The following options manipulate hostranged output. See HOSTRANGED SUP‐
207 PORT below for additional information on hostranges.
208 -B, --buffer-output
210 Buffer hostranged output. For each node, buffer standard output
211 until the node has completed its IPMI operation. When specifying
212 this option, data may appear to output slower to the user since
213 the the entire IPMI operation must complete before any data can
214 be output. See HOSTRANGED SUPPORT below for additional informa‐
215 tion.
216 -C, --consolidate-output
218 Consolidate hostranged output. The complete standard output from
219 every node specified will be consolidated so that nodes with
220 identical output are not output twice. A header will list those
221 nodes with the consolidated output. When this option is speci‐
222 fied, no output can be seen until the IPMI operations to all
223 nodes has completed. If the user breaks out of the program
224 early, all currently consolidated output will be dumped. See
225 HOSTRANGED SUPPORT below for additional information.
226 -F NUM, --fanout=NUM
228 Specify multiple host fanout. A "sliding window" (or fanout)
229 algorithm is used for parallel IPMI communication so that slower
230 nodes or timed out nodes will not impede parallel communication.
231 The maximum number of threads available at the same time is lim‐
232 ited by the fanout. The default is 64.
233 -E, --eliminate
235 Eliminate hosts determined as undetected by ipmidetect. This
236 attempts to remove the common issue of hostranged execution tim‐
237 ing out due to several nodes being removed from service in a
238 large cluster. The ipmidetectd daemon must be running on the
239 node executing the command.
240 --always-prefix
242 Always prefix output, even if only one host is specified or com‐
243 municating in-band. This option is primarily useful for script‐
244 ing purposes. Option will be ignored if specified with the -C
245 option.
246
248 Multiple hosts can be input either as an explicit comma separated lists
249 of hosts or a range of hostnames in the general form: prefix[n-m,l-
250 k,...], where n < m and l < k, etc. The later form should not be con‐
251 fused with regular expression character classes (also denoted by []).
252 For example, foo[19] does not represent foo1 or foo9, but rather repre‐
253 sents a degenerate range: foo19.
254 This range syntax is meant only as a convenience on clusters with a
256 prefixNN naming convention and specification of ranges should not be
257 considered necessary -- the list foo1,foo9 could be specified as such,
258 or by the range foo[1,9].
259 Some examples of range usage follow:
261 foo[01-05] instead of foo01,foo02,foo03,foo04,foo05
262 foo[7,9-10] instead of foo7,foo9,foo10
263 foo[0-3] instead of foo0,foo1,foo2,foo3
264 As a reminder to the reader, some shells will interpret brackets ([ and
266 ]) for pattern matching. Depending on your shell, it may be necessary
267 to enclose ranged lists within quotes.
268 When multiple hosts are specified by the user, a thread will be exe‐
270 cuted for each host in parallel up to the configured fanout (which can
271 be adjusted via the -F option). This will allow communication to large
272 numbers of nodes far more quickly than if done in serial.
273 By default, standard output from each node specified will be output
275 with the hostname prepended to each line. Although this output is read‐
276 able in many situations, it may be difficult to read in other situa‐
277 tions. For example, output from multiple nodes may be mixed together.
278 The -B and -C options can be used to change this default.
279 In-band IPMI Communication will be used when the host "localhost" is
281 specified. This allows the user to add the localhost into the hos‐
282 tranged output.
283
285 Most often, IPMI problems are due to configuration problems.
286 IPMI over LAN problems involve a misconfiguration of the remote
288 machine's BMC. Double check to make sure the following are configured
289 properly in the remote machine's BMC: IP address, MAC address, subnet
290 mask, username, user enablement, user privilege, password, LAN privi‐
291 lege, LAN enablement, and allowed authentication type(s). For IPMI 2.0
292 connections, double check to make sure the cipher suite privilege(s)
293 and K_g key are configured properly. The ipmi-config(8) tool can be
294 used to check and/or change these configuration settings.
295 Inband IPMI problems are typically caused by improperly configured
297 drivers or non-standard BMCs.
298 In addition to the troubleshooting tips below, please see WORKAROUNDS
300 below to also if there are any vendor specific bugs that have been dis‐
301 covered and worked around.
302 Listed below are many of the common issues for error messages. For
304 additional support, please e-mail the <freeipmi-users@gnu.org> mailing
305 list.
306 "username invalid" - The username entered (or a NULL username if none
308 was entered) is not available on the remote machine. It may also be
309 possible the remote BMC's username configuration is incorrect.
310 "password invalid" - The password entered (or a NULL password if none
312 was entered) is not correct. It may also be possible the password for
313 the user is not correctly configured on the remote BMC.
314 "password verification timeout" - Password verification has timed out.
316 A "password invalid" error (described above) or a generic "session
317 timeout" (described below) occurred. During this point in the protocol
318 it cannot be differentiated which occurred.
319 "k_g invalid" - The K_g key entered (or a NULL K_g key if none was
321 entered) is not correct. It may also be possible the K_g key is not
322 correctly configured on the remote BMC.
323 "privilege level insufficient" - An IPMI command requires a higher user
325 privilege than the one authenticated with. Please try to authenticate
326 with a higher privilege. This may require authenticating to a different
327 user which has a higher maximum privilege.
328 "privilege level cannot be obtained for this user" - The privilege
330 level you are attempting to authenticate with is higher than the maxi‐
331 mum allowed for this user. Please try again with a lower privilege. It
332 may also be possible the maximum privilege level allowed for a user is
333 not configured properly on the remote BMC.
334 "authentication type unavailable for attempted privilege level" - The
336 authentication type you wish to authenticate with is not available for
337 this privilege level. Please try again with an alternate authentication
338 type or alternate privilege level. It may also be possible the avail‐
339 able authentication types you can authenticate with are not correctly
340 configured on the remote BMC.
341 "cipher suite id unavailable" - The cipher suite id you wish to authen‐
343 ticate with is not available on the remote BMC. Please try again with
344 an alternate cipher suite id. It may also be possible the available
345 cipher suite ids are not correctly configured on the remote BMC.
346 "ipmi 2.0 unavailable" - IPMI 2.0 was not discovered on the remote
348 machine. Please try to use IPMI 1.5 instead.
349 "connection timeout" - Initial IPMI communication failed. A number of
351 potential errors are possible, including an invalid hostname specified,
352 an IPMI IP address cannot be resolved, IPMI is not enabled on the
353 remote server, the network connection is bad, etc. Please verify con‐
354 figuration and connectivity.
355 "session timeout" - The IPMI session has timed out. Please reconnect.
357 If this error occurs often, you may wish to increase the retransmission
358 timeout. Some remote BMCs are considerably slower than others.
359 "device not found" - The specified device could not be found. Please
361 check configuration or inputs and try again.
362 "driver timeout" - Communication with the driver or device has timed
364 out. Please try again.
365 "message timeout" - Communication with the driver or device has timed
367 out. Please try again.
368 "BMC busy" - The BMC is currently busy. It may be processing informa‐
370 tion or have too many simultaneous sessions to manage. Please wait and
371 try again.
372 "could not find inband device" - An inband device could not be found.
374 Please check configuration or specify specific device or driver on the
375 command line.
376 "driver timeout" - The inband driver has timed out communicating to the
378 local BMC or service processor. The BMC or service processor may be
379 busy or (worst case) possibly non-functioning.
380
382 With so many different vendors implementing their own IPMI solutions,
383 different vendors may implement their IPMI protocols incorrectly. The
384 following describes a number of workarounds currently available to han‐
385 dle discovered compliance issues. When possible, workarounds have been
386 implemented so they will be transparent to the user. However, some will
387 require the user to specify a workaround be used via the -W option.
388 The hardware listed below may only indicate the hardware that a problem
390 was discovered on. Newer versions of hardware may fix the problems
391 indicated below. Similar machines from vendors may or may not exhibit
392 the same problems. Different vendors may license their firmware from
393 the same IPMI firmware developer, so it may be worthwhile to try work‐
394 arounds listed below even if your motherboard is not listed.
395 If you believe your hardware has an additional compliance issue that
397 needs a workaround to be implemented, please contact the FreeIPMI main‐
398 tainers on <freeipmi-users@gnu.org> or <freeipmi-devel@gnu.org>.
399 assumeio - This workaround flag will assume inband interfaces communi‐
401 cate with system I/O rather than being memory-mapped. This will work
402 around systems that report invalid base addresses. Those hitting this
403 issue may see "device not supported" or "could not find inband device"
404 errors. Issue observed on HP ProLiant DL145 G1.
405 spinpoll - This workaround flag will inform some inband drivers (most
407 notably the KCS driver) to spin while polling rather than putting the
408 process to sleep. This may significantly improve the wall clock running
409 time of tools because an operating system scheduler's granularity may
410 be much larger than the time it takes to perform a single IPMI message
411 transaction. However, by spinning, your system may be performing less
412 useful work by not contexting out the tool for a more useful task.
413 authcap - This workaround flag will skip early checks for username
415 capabilities, authentication capabilities, and K_g support and allow
416 IPMI authentication to succeed. It works around multiple issues in
417 which the remote system does not properly report username capabilities,
418 authentication capabilities, or K_g status. Those hitting this issue
419 may see "username invalid", "authentication type unavailable for
420 attempted privilege level", or "k_g invalid" errors. Issue observed on
421 Asus P5M2/P5MT-R/RS162-E4/RX4, Intel SR1520ML/X38ML, and Sun Fire
422 2200/4150/4450 with ELOM.
423 nochecksumcheck - This workaround flag will tell FreeIPMI to not check
425 the checksums returned from IPMI command responses. It works around
426 systems that return invalid checksums due to implementation errors, but
427 the packet is otherwise valid. Users are cautioned on the use of this
428 option, as it removes validation of packet integrity in a number of
429 circumstances. However, it is unlikely to be an issue in most situa‐
430 tions. Those hitting this issue may see "connection timeout", "session
431 timeout", or "password verification timeout" errors. On IPMI 1.5 con‐
432 nections, the "noauthcodecheck" workaround may also needed too. Issue
433 observed on Supermicro X9SCM-iiF, Supermicro X9DRi-F, and Supermicro
434 X9DRFR.
435 idzero - This workaround flag will allow empty session IDs to be
437 accepted by the client. It works around IPMI sessions that report empty
438 session IDs to the client. Those hitting this issue may see "session
439 timeout" errors. Issue observed on Tyan S2882 with M3289 BMC.
440 unexpectedauth - This workaround flag will allow unexpected non-null
442 authcodes to be checked as though they were expected. It works around
443 an issue when packets contain non-null authentication data when they
444 should be null due to disabled per-message authentication. Those hit‐
445 ting this issue may see "session timeout" errors. Issue observed on
446 Dell PowerEdge 2850,SC1425. Confirmed fixed on newer firmware.
447 forcepermsg - This workaround flag will force per-message authentica‐
449 tion to be used no matter what is advertised by the remote system. It
450 works around an issue when per-message authentication is advertised as
451 disabled on the remote system, but it is actually required for the pro‐
452 tocol. Those hitting this issue may see "session timeout" errors.
453 Issue observed on IBM eServer 325.
454 endianseq - This workaround flag will flip the endian of the session
456 sequence numbers to allow the session to continue properly. It works
457 around IPMI 1.5 session sequence numbers that are the wrong endian.
458 Those hitting this issue may see "session timeout" errors. Issue
459 observed on some Sun ILOM 1.0/2.0 (depends on service processor
460 endian).
461 noauthcodecheck - This workaround flag will tell FreeIPMI to not check
463 the authentication codes returned from IPMI 1.5 command responses. It
464 works around systems that return invalid authentication codes due to
465 hashing or implementation errors. Users are cautioned on the use of
466 this option, as it removes an authentication check verifying the valid‐
467 ity of a packet. However, in most organizations, this is unlikely to be
468 a security issue. Those hitting this issue may see "connection time‐
469 out", "session timeout", or "password verification timeout" errors.
470 Issue observed on Xyratex FB-H8-SRAY, Intel Windmill, Quanta Winter‐
471 fell, and Wiwynn Windmill.
472 intel20 - This workaround flag will work around several Intel IPMI 2.0
474 authentication issues. The issues covered include padding of usernames,
475 and password truncation if the authentication algorithm is HMAC-
476 MD5-128. Those hitting this issue may see "username invalid", "password
477 invalid", or "k_g invalid" errors. Issue observed on Intel SE7520AF2
478 with Intel Server Management Module (Professional Edition).
479 supermicro20 - This workaround flag will work around several Supermicro
481 IPMI 2.0 authentication issues on motherboards w/ Peppercon IPMI
482 firmware. The issues covered include handling invalid length authenti‐
483 cation codes. Those hitting this issue may see "password invalid"
484 errors. Issue observed on Supermicro H8QME with SIMSO daughter card.
485 Confirmed fixed on newerver firmware.
486 sun20 - This workaround flag will work work around several Sun IPMI 2.0
488 authentication issues. The issues covered include invalid lengthed hash
489 keys, improperly hashed keys, and invalid cipher suite records. Those
490 hitting this issue may see "password invalid" or "bmc error" errors.
491 Issue observed on Sun Fire 4100/4200/4500 with ILOM. This workaround
492 automatically includes the "opensesspriv" workaround.
493 opensesspriv - This workaround flag will slightly alter FreeIPMI's IPMI
495 2.0 connection protocol to workaround an invalid hashing algorithm used
496 by the remote system. The privilege level sent during the Open Session
497 stage of an IPMI 2.0 connection is used for hashing keys instead of the
498 privilege level sent during the RAKP1 connection stage. Those hitting
499 this issue may see "password invalid", "k_g invalid", or "bad rmcpplus
500 status code" errors. Issue observed on Sun Fire 4100/4200/4500 with
501 ILOM, Inventec 5441/Dell Xanadu II, Supermicro X8DTH, Supermicro X8DTG,
502 Intel S5500WBV/Penguin Relion 700, Intel S2600JF/Appro 512X, and Quanta
503 QSSC-S4R/Appro GB812X-CN. This workaround is automatically triggered
504 with the "sun20" workaround.
505 integritycheckvalue - This workaround flag will work around an invalid
507 integrity check value during an IPMI 2.0 session establishment when
508 using Cipher Suite ID 0. The integrity check value should be 0 length,
509 however the remote motherboard responds with a non-empty field. Those
510 hitting this issue may see "k_g invalid" errors. Issue observed on
511 Supermicro X8DTG, Supermicro X8DTU, and Intel S5500WBV/Penguin Relion
512 700, and Intel S2600JF/Appro 512X.
513 guidformat - A number of vendors send the bytes of the GUID (such as
515 the GUID in --get-device-guid or --get-system-guid) in an alternate
516 format that aligns incorrectly with IPMI, but correctly with other
517 standards. This workaround flag will instruct bmc-info to read the GUID
518 and output the GUID based on this common alternate format.
519 No IPMI 1.5 Support - Some motherboards that support IPMI 2.0 have been
521 found to not support IPMI 1.5. Those hitting this issue may see "ipmi
522 2.0 unavailable" or "connection timeout" errors. This issue can be
523 worked around by using IPMI 2.0 instead of IPMI 1.5 by specifying
524 --driver-type=LAN_2_0. Issue observed on HP Proliant DL 145.
525
527 The following motherboards are confirmed to have atleast some support
528 by the --interpret-oem-data option. While highly probable the OEM data
529 interpretations would work across other motherboards by the same manu‐
530 facturer, there are no guarantees. Some of the motherboards below may
531 be rebranded by vendors/distributors.
532 Dell Poweredge R610, Dell Poweredge R710, Intel SR870BN4/Tiger4
534
536 # bmc-info
537 Get BMC information of the local machine.
539 # bmc-info -h ahost -u myusername -p mypassword
541 Get BMC information of a remote machine using IPMI over LAN.
543 # bmc-info -h mycluster[0-127] -u myusername -p mypassword
545 Get BMC information across a cluster using IPMI over LAN.
547
549 Upon successful execution, exit status is 0. On error, exit status is
550 1.
551 If multiple hosts are specified for communication, the exit status is 0
553 if and only if all targets successfully execute. Otherwise the exit
554 status is 1.
555
557 On older operating systems, if you input your username, password, and
558 other potentially security relevant information on the command line,
559 this information may be discovered by other users when using tools like
