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. If specifying an IPv6 address and port,
62 use the format [ADDRESS]:PORT.
63 -u USERNAME, --username=USERNAME
65 Specify the username to use when authenticating with the remote
66 host. If not specified, a null (i.e. anonymous) username is
67 assumed. The user must have atleast USER privileges in order for
68 this tool to operate fully.
69 -p PASSWORD, --password=PASSWORD
71 Specify the password to use when authenticationg with the remote
72 host. If not specified, a null password is assumed. Maximum
73 password length is 16 for IPMI 1.5 and 20 for IPMI 2.0.
74 -P, --password-prompt
76 Prompt for password to avoid possibility of listing it in
77 process lists.
78 -k K_G, --k-g=K_G
80 Specify the K_g BMC key to use when authenticating with the
81 remote host for IPMI 2.0. If not specified, a null key is
82 assumed. To input the key in hexadecimal form, prefix the string
83 with '0x'. E.g., the key 'abc' can be entered with the either
84 the string 'abc' or the string '0x616263'
85 -K, --k-g-prompt
87 Prompt for k-g to avoid possibility of listing it in process
88 lists.
89 --session-timeout=MILLISECONDS
91 Specify the session timeout in milliseconds. Defaults to 20000
92 milliseconds (20 seconds) if not specified.
93 --retransmission-timeout=MILLISECONDS
95 Specify the packet retransmission timeout in milliseconds.
96 Defaults to 1000 milliseconds (1 second) if not specified. The
97 retransmission timeout cannot be larger than the session time‐
98 out.
99 -a AUTHENTICATION-TYPE, --authentication-type=AUTHENTICATION-TYPE
101 Specify the IPMI 1.5 authentication type to use. The currently
102 available authentication types are NONE, STRAIGHT_PASSWORD_KEY,
103 MD2, and MD5. Defaults to MD5 if not specified.
104 -I CIPHER-SUITE-ID, --cipher-suite-id=CIPHER-SUITE-ID
106 Specify the IPMI 2.0 cipher suite ID to use. The Cipher Suite ID
107 identifies a set of authentication, integrity, and confidential‐
108 ity algorithms to use for IPMI 2.0 communication. The authenti‐
109 cation algorithm identifies the algorithm to use for session
110 setup, the integrity algorithm identifies the algorithm to use
111 for session packet signatures, and the confidentiality algorithm
112 identifies the algorithm to use for payload encryption. Defaults
113 to cipher suite ID 3 if not specified. The following cipher
114 suite ids are currently supported:
115 0 - Authentication Algorithm = None; Integrity Algorithm = None;
117 Confidentiality Algorithm = None
118 1 - Authentication Algorithm = HMAC-SHA1; Integrity Algorithm =
120 None; Confidentiality Algorithm = None
121 2 - Authentication Algorithm = HMAC-SHA1; Integrity Algorithm =
123 HMAC-SHA1-96; Confidentiality Algorithm = None
124 3 - Authentication Algorithm = HMAC-SHA1; Integrity Algorithm =
126 HMAC-SHA1-96; Confidentiality Algorithm = AES-CBC-128
127 6 - Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
129 None; Confidentiality Algorithm = None
130 7 - Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
132 HMAC-MD5-128; Confidentiality Algorithm = None
133 8 - Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
135 HMAC-MD5-128; Confidentiality Algorithm = AES-CBC-128
136 11 - Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
138 MD5-128; Confidentiality Algorithm = None
139 12 - Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
141 MD5-128; Confidentiality Algorithm = AES-CBC-128
142 15 - Authentication Algorithm = HMAC-SHA256; Integrity Algorithm
144 = None; Confidentiality Algorithm = None
145 16 - Authentication Algorithm = HMAC-SHA256; Integrity Algorithm
147 = HMAC_SHA256_128; Confidentiality Algorithm = None
148 17 - Authentication Algorithm = HMAC-SHA256; Integrity Algorithm
150 = HMAC_SHA256_128; Confidentiality Algorithm = AES-CBC-128
151 -l PRIVILEGE-LEVEL, --privilege-level=PRIVILEGE-LEVEL
153 Specify the privilege level to be used. The currently available
154 privilege levels are USER, OPERATOR, and ADMIN. Defaults to USER
155 if not specified.
156 --config-file=FILE
158 Specify an alternate configuration file.
159 -W WORKAROUNDS, --workaround-flags=WORKAROUNDS
161 Specify workarounds to vendor compliance issues. Multiple work‐
162 arounds can be specified separated by commas. A special command
163 line flag of "none", will indicate no workarounds (may be useful
164 for overriding configured defaults). See WORKAROUNDS below for a
165 list of available workarounds.
166 --debug
168 Turn on debugging.
169 -?, --help
171 Output a help list and exit.
172 --usage
174 Output a usage message and exit.
175 -V, --version
177 Output the program version and exit.
178
180 The following options are specific to bmc-info.
181 --get-device-id
183 Display only device ID information.
184 --get-device-guid
186 Display only device guid.
187 --get-system-guid
189 Display only system guid.
190 --get-system-info
192 Display only system info.
193 --get-channel-info
195 Display only channel information.
196 --interpret-oem-data
198 Attempt to interpret OEM data, such as event data, sensor read‐
199 ings, or general extra info, etc. If an OEM interpretation is
200 not available, the default output will be generated. Correctness
201 of OEM interpretations cannot be guaranteed due to potential
202 changes OEM vendors may make in products, firmware, etc. See OEM
203 INTERPRETATION below for confirmed supported motherboard inter‐
204 pretations.
205
207 The following options manipulate hostranged output. See HOSTRANGED SUP‐
208 PORT below for additional information on hostranges.
209 -B, --buffer-output
211 Buffer hostranged output. For each node, buffer standard output
212 until the node has completed its IPMI operation. When specifying
213 this option, data may appear to output slower to the user since
214 the the entire IPMI operation must complete before any data can
215 be output. See HOSTRANGED SUPPORT below for additional informa‐
216 tion.
217 -C, --consolidate-output
219 Consolidate hostranged output. The complete standard output from
220 every node specified will be consolidated so that nodes with
221 identical output are not output twice. A header will list those
222 nodes with the consolidated output. When this option is speci‐
223 fied, no output can be seen until the IPMI operations to all
224 nodes has completed. If the user breaks out of the program
225 early, all currently consolidated output will be dumped. See
226 HOSTRANGED SUPPORT below for additional information.
227 -F NUM, --fanout=NUM
229 Specify multiple host fanout. A "sliding window" (or fanout)
230 algorithm is used for parallel IPMI communication so that slower
231 nodes or timed out nodes will not impede parallel communication.
232 The maximum number of threads available at the same time is lim‐
233 ited by the fanout. The default is 64.
234 -E, --eliminate
236 Eliminate hosts determined as undetected by ipmidetect. This
237 attempts to remove the common issue of hostranged execution tim‐
238 ing out due to several nodes being removed from service in a
239 large cluster. The ipmidetectd daemon must be running on the
240 node executing the command.
241 --always-prefix
243 Always prefix output, even if only one host is specified or com‐
244 municating in-band. This option is primarily useful for script‐
245 ing purposes. Option will be ignored if specified with the -C
246 option.
247
249 Multiple hosts can be input either as an explicit comma separated lists
250 of hosts or a range of hostnames in the general form: prefix[n-m,l-
251 k,...], where n < m and l < k, etc. The later form should not be con‐
252 fused with regular expression character classes (also denoted by []).
253 For example, foo[19] does not represent foo1 or foo9, but rather repre‐
254 sents a degenerate range: foo19.
255 This range syntax is meant only as a convenience on clusters with a
257 prefixNN naming convention and specification of ranges should not be
258 considered necessary -- the list foo1,foo9 could be specified as such,
259 or by the range foo[1,9].
260 Some examples of range usage follow:
262 foo[01-05] instead of foo01,foo02,foo03,foo04,foo05
263 foo[7,9-10] instead of foo7,foo9,foo10
264 foo[0-3] instead of foo0,foo1,foo2,foo3
265 As a reminder to the reader, some shells will interpret brackets ([ and
267 ]) for pattern matching. Depending on your shell, it may be necessary
268 to enclose ranged lists within quotes.
269 When multiple hosts are specified by the user, a thread will be exe‐
271 cuted for each host in parallel up to the configured fanout (which can
272 be adjusted via the -F option). This will allow communication to large
273 numbers of nodes far more quickly than if done in serial.
274 By default, standard output from each node specified will be output
276 with the hostname prepended to each line. Although this output is read‐
277 able in many situations, it may be difficult to read in other situa‐
278 tions. For example, output from multiple nodes may be mixed together.
279 The -B and -C options can be used to change this default.
280 In-band IPMI Communication will be used when the host "localhost" is
282 specified. This allows the user to add the localhost into the hos‐
283 tranged output.
284
286 Most often, IPMI problems are due to configuration problems.
287 IPMI over LAN problems involve a misconfiguration of the remote
289 machine's BMC. Double check to make sure the following are configured
290 properly in the remote machine's BMC: IP address, MAC address, subnet
291 mask, username, user enablement, user privilege, password, LAN privi‐
292 lege, LAN enablement, and allowed authentication type(s). For IPMI 2.0
293 connections, double check to make sure the cipher suite privilege(s)
294 and K_g key are configured properly. The ipmi-config(8) tool can be
295 used to check and/or change these configuration settings.
296 Inband IPMI problems are typically caused by improperly configured
298 drivers or non-standard BMCs.
299 In addition to the troubleshooting tips below, please see WORKAROUNDS
301 below to also if there are any vendor specific bugs that have been dis‐
302 covered and worked around.
303 Listed below are many of the common issues for error messages. For
305 additional support, please e-mail the <freeipmi-users@gnu.org> mailing
306 list.
307 "username invalid" - The username entered (or a NULL username if none
309 was entered) is not available on the remote machine. It may also be
310 possible the remote BMC's username configuration is incorrect.
311 "password invalid" - The password entered (or a NULL password if none
313 was entered) is not correct. It may also be possible the password for
314 the user is not correctly configured on the remote BMC.
315 "password verification timeout" - Password verification has timed out.
317 A "password invalid" error (described above) or a generic "session
318 timeout" (described below) occurred. During this point in the protocol
319 it cannot be differentiated which occurred.
320 "k_g invalid" - The K_g key entered (or a NULL K_g key if none was
322 entered) is not correct. It may also be possible the K_g key is not
323 correctly configured on the remote BMC.
324 "privilege level insufficient" - An IPMI command requires a higher user
326 privilege than the one authenticated with. Please try to authenticate
327 with a higher privilege. This may require authenticating to a different
328 user which has a higher maximum privilege.
329 "privilege level cannot be obtained for this user" - The privilege
331 level you are attempting to authenticate with is higher than the maxi‐
332 mum allowed for this user. Please try again with a lower privilege. It
333 may also be possible the maximum privilege level allowed for a user is
334 not configured properly on the remote BMC.
335 "authentication type unavailable for attempted privilege level" - The
337 authentication type you wish to authenticate with is not available for
338 this privilege level. Please try again with an alternate authentication
339 type or alternate privilege level. It may also be possible the avail‐
340 able authentication types you can authenticate with are not correctly
341 configured on the remote BMC.
342 "cipher suite id unavailable" - The cipher suite id you wish to authen‐
344 ticate with is not available on the remote BMC. Please try again with
345 an alternate cipher suite id. It may also be possible the available
346 cipher suite ids are not correctly configured on the remote BMC.
347 "ipmi 2.0 unavailable" - IPMI 2.0 was not discovered on the remote
349 machine. Please try to use IPMI 1.5 instead.
350 "connection timeout" - Initial IPMI communication failed. A number of
352 potential errors are possible, including an invalid hostname specified,
353 an IPMI IP address cannot be resolved, IPMI is not enabled on the
354 remote server, the network connection is bad, etc. Please verify con‐
355 figuration and connectivity.
356 "session timeout" - The IPMI session has timed out. Please reconnect.
358 If this error occurs often, you may wish to increase the retransmission
359 timeout. Some remote BMCs are considerably slower than others.
360 "device not found" - The specified device could not be found. Please
362 check configuration or inputs and try again.
363 "driver timeout" - Communication with the driver or device has timed
365 out. Please try again.
366 "message timeout" - Communication with the driver or device has timed
368 out. Please try again.
369 "BMC busy" - The BMC is currently busy. It may be processing informa‐
371 tion or have too many simultaneous sessions to manage. Please wait and
372 try again.
373 "could not find inband device" - An inband device could not be found.
375 Please check configuration or specify specific device or driver on the
376 command line.
377 "driver timeout" - The inband driver has timed out communicating to the
379 local BMC or service processor. The BMC or service processor may be
380 busy or (worst case) possibly non-functioning.
381
383 With so many different vendors implementing their own IPMI solutions,
384 different vendors may implement their IPMI protocols incorrectly. The
385 following describes a number of workarounds currently available to han‐
386 dle discovered compliance issues. When possible, workarounds have been
387 implemented so they will be transparent to the user. However, some will
388 require the user to specify a workaround be used via the -W option.
389 The hardware listed below may only indicate the hardware that a problem
391 was discovered on. Newer versions of hardware may fix the problems
392 indicated below. Similar machines from vendors may or may not exhibit
393 the same problems. Different vendors may license their firmware from
394 the same IPMI firmware developer, so it may be worthwhile to try work‐
395 arounds listed below even if your motherboard is not listed.
396 If you believe your hardware has an additional compliance issue that
398 needs a workaround to be implemented, please contact the FreeIPMI main‐
399 tainers on <freeipmi-users@gnu.org> or <freeipmi-devel@gnu.org>.
400 assumeio - This workaround flag will assume inband interfaces communi‐
402 cate with system I/O rather than being memory-mapped. This will work
403 around systems that report invalid base addresses. Those hitting this
404 issue may see "device not supported" or "could not find inband device"
405 errors. Issue observed on HP ProLiant DL145 G1.
406 spinpoll - This workaround flag will inform some inband drivers (most
408 notably the KCS driver) to spin while polling rather than putting the
409 process to sleep. This may significantly improve the wall clock running
410 time of tools because an operating system scheduler's granularity may
411 be much larger than the time it takes to perform a single IPMI message
412 transaction. However, by spinning, your system may be performing less
413 useful work by not contexting out the tool for a more useful task.
414 authcap - This workaround flag will skip early checks for username
416 capabilities, authentication capabilities, and K_g support and allow
417 IPMI authentication to succeed. It works around multiple issues in
418 which the remote system does not properly report username capabilities,
419 authentication capabilities, or K_g status. Those hitting this issue
420 may see "username invalid", "authentication type unavailable for
421 attempted privilege level", or "k_g invalid" errors. Issue observed on
422 Asus P5M2/P5MT-R/RS162-E4/RX4, Intel SR1520ML/X38ML, and Sun Fire
423 2200/4150/4450 with ELOM.
424 nochecksumcheck - This workaround flag will tell FreeIPMI to not check
426 the checksums returned from IPMI command responses. It works around
427 systems that return invalid checksums due to implementation errors, but
428 the packet is otherwise valid. Users are cautioned on the use of this
429 option, as it removes validation of packet integrity in a number of
430 circumstances. However, it is unlikely to be an issue in most situa‐
431 tions. Those hitting this issue may see "connection timeout", "session
432 timeout", or "password verification timeout" errors. On IPMI 1.5 con‐
433 nections, the "noauthcodecheck" workaround may also needed too. Issue
434 observed on Supermicro X9SCM-iiF, Supermicro X9DRi-F, and Supermicro
435 X9DRFR.
436 idzero - This workaround flag will allow empty session IDs to be
438 accepted by the client. It works around IPMI sessions that report empty
439 session IDs to the client. Those hitting this issue may see "session
440 timeout" errors. Issue observed on Tyan S2882 with M3289 BMC.
441 unexpectedauth - This workaround flag will allow unexpected non-null
443 authcodes to be checked as though they were expected. It works around
444 an issue when packets contain non-null authentication data when they
445 should be null due to disabled per-message authentication. Those hit‐
446 ting this issue may see "session timeout" errors. Issue observed on
447 Dell PowerEdge 2850,SC1425. Confirmed fixed on newer firmware.
448 forcepermsg - This workaround flag will force per-message authentica‐
450 tion to be used no matter what is advertised by the remote system. It
451 works around an issue when per-message authentication is advertised as
452 disabled on the remote system, but it is actually required for the pro‐
453 tocol. Those hitting this issue may see "session timeout" errors.
454 Issue observed on IBM eServer 325.
455 endianseq - This workaround flag will flip the endian of the session
457 sequence numbers to allow the session to continue properly. It works
458 around IPMI 1.5 session sequence numbers that are the wrong endian.
459 Those hitting this issue may see "session timeout" errors. Issue
460 observed on some Sun ILOM 1.0/2.0 (depends on service processor
461 endian).
462 noauthcodecheck - This workaround flag will tell FreeIPMI to not check
464 the authentication codes returned from IPMI 1.5 command responses. It
465 works around systems that return invalid authentication codes due to
466 hashing or implementation errors. Users are cautioned on the use of
467 this option, as it removes an authentication check verifying the valid‐
468 ity of a packet. However, in most organizations, this is unlikely to be
469 a security issue. Those hitting this issue may see "connection time‐
470 out", "session timeout", or "password verification timeout" errors.
471 Issue observed on Xyratex FB-H8-SRAY, Intel Windmill, Quanta Winter‐
472 fell, and Wiwynn Windmill.
473 intel20 - This workaround flag will work around several Intel IPMI 2.0
475 authentication issues. The issues covered include padding of usernames,
476 and password truncation if the authentication algorithm is HMAC-
477 MD5-128. Those hitting this issue may see "username invalid", "password
478 invalid", or "k_g invalid" errors. Issue observed on Intel SE7520AF2
479 with Intel Server Management Module (Professional Edition).
480 supermicro20 - This workaround flag will work around several Supermicro
482 IPMI 2.0 authentication issues on motherboards w/ Peppercon IPMI
483 firmware. The issues covered include handling invalid length authenti‐
484 cation codes. Those hitting this issue may see "password invalid"
485 errors. Issue observed on Supermicro H8QME with SIMSO daughter card.
486 Confirmed fixed on newerver firmware.
487 sun20 - This workaround flag will work work around several Sun IPMI 2.0
489 authentication issues. The issues covered include invalid lengthed hash
490 keys, improperly hashed keys, and invalid cipher suite records. Those
491 hitting this issue may see "password invalid" or "bmc error" errors.
492 Issue observed on Sun Fire 4100/4200/4500 with ILOM. This workaround
493 automatically includes the "opensesspriv" workaround.
494 opensesspriv - This workaround flag will slightly alter FreeIPMI's IPMI
496 2.0 connection protocol to workaround an invalid hashing algorithm used
497 by the remote system. The privilege level sent during the Open Session
498 stage of an IPMI 2.0 connection is used for hashing keys instead of the
499 privilege level sent during the RAKP1 connection stage. Those hitting
500 this issue may see "password invalid", "k_g invalid", or "bad rmcpplus
501 status code" errors. Issue observed on Sun Fire 4100/4200/4500 with
502 ILOM, Inventec 5441/Dell Xanadu II, Supermicro X8DTH, Supermicro X8DTG,
503 Intel S5500WBV/Penguin Relion 700, Intel S2600JF/Appro 512X, Quanta
504 QSSC-S4R/Appro GB812X-CN, and Dell C5220. This workaround is automati‐
505 cally triggered with the "sun20" workaround.
506 integritycheckvalue - This workaround flag will work around an invalid
508 integrity check value during an IPMI 2.0 session establishment when
509 using Cipher Suite ID 0. The integrity check value should be 0 length,
510 however the remote motherboard responds with a non-empty field. Those
511 hitting this issue may see "k_g invalid" errors. Issue observed on
512 Supermicro X8DTG, Supermicro X8DTU, and Intel S5500WBV/Penguin Relion
513 700, and Intel S2600JF/Appro 512X.
514 guidformat - A number of vendors send the bytes of the GUID (such as
516 the GUID in --get-device-guid or --get-system-guid) in an alternate
517 format that aligns incorrectly with IPMI, but correctly with other
518 standards. This workaround flag will instruct bmc-info to read the GUID
519 and output the GUID based on this common alternate format.
520 No IPMI 1.5 Support - Some motherboards that support IPMI 2.0 have been
522 found to not support IPMI 1.5. Those hitting this issue may see "ipmi
523 2.0 unavailable" or "connection timeout" errors. This issue can be
524 worked around by using IPMI 2.0 instead of IPMI 1.5 by specifying
525 --driver-type=LAN_2_0. Issue observed on a number of HP and Supermicro
526 motherboards.
527
529 The following motherboards are confirmed to have atleast some support
530 by the --interpret-oem-data option. While highly probable the OEM data
531 interpretations would work across other motherboards by the same manu‐
532 facturer, there are no guarantees. Some of the motherboards below may
533 be rebranded by vendors/distributors.
534 Dell Poweredge R610, Dell Poweredge R710, Intel SR870BN4/Tiger4
536
538 # bmc-info
539 Get BMC information of the local machine.
541 # bmc-info -h ahost -u myusername -p mypassword
543 Get BMC information of a remote machine using IPMI over LAN.
545 # bmc-info -h mycluster[0-127] -u myusername -p mypassword
547 Get BMC information across a cluster using IPMI over LAN.
549
551 Upon successful execution, exit status is 0. On error, exit status is
552 1.
553 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
559 On older operating systems, if you input your username, password, and
