6 ipmiseld - IPMI SEL logging daemon
7
9 ipmiseld [OPTION...]
10
12 The ipmiseld daemon polls the system event log (SEL) of specified hosts
13 and stores the logs into the local syslog. By default, the daemon can
14 also make best efforts to manage the remote SEL's buffer to ensure
15 events are never lost. Recent logging data will be cached to disk to
16 ensure that SEL events are not missed in the event the client or server
17 is rebooted.
18 Many of the options for this daemon are very similar to the ipmi-sel(8)
20 tool. It can be configured to log the local host, a remote host, or a
21 range of hosts to the local syslog. It can be configured via the com‐
22 mand line arguments listed below or via the /etc/freeipmi//ip‐
23 miseld.conf configuration file.
24 Listed below are general IPMI options, tool specific options, trouble
26 shooting information, workaround information, examples, and known is‐
27 sues. For a general introduction to FreeIPMI please see freeipmi(7).
28
30 The following options are general options for configuring IPMI communi‐
31 cation and executing general tool commands.
32 -D IPMIDRIVER, --driver-type=IPMIDRIVER
34 Specify the driver type to use instead of doing an auto selec‐
35 tion. The currently available outofband drivers are LAN and
36 LAN_2_0, which perform IPMI 1.5 and IPMI 2.0 respectively. The
37 currently available inband drivers are KCS, SSIF, OPENIPMI,
38 SUNBMC, and INTELDCMI.
39 --disable-auto-probe
41 Do not probe in-band IPMI devices for default settings.
42 --driver-address=DRIVER-ADDRESS
44 Specify the in-band driver address to be used instead of the
45 probed value. DRIVER-ADDRESS should be prefixed with "0x" for a
46 hex value and '0' for an octal value.
47 --driver-device=DEVICE
49 Specify the in-band driver device path to be used instead of the
50 probed path.
51 --register-spacing=REGISTER-SPACING
53 Specify the in-band driver register spacing instead of the
54 probed value. Argument is in bytes (i.e. 32bit register spacing
55 = 4)
56 --target-channel-number=CHANNEL-NUMBER
58 Specify the in-band driver target channel number to send IPMI
59 requests to.
60 --target-slave-address=SLAVE-ADDRESS
62 Specify the in-band driver target slave number to send IPMI re‐
63 quests to.
64 -h IPMIHOST1,IPMIHOST2,..., --hostname=IPMIHOST1[:PORT],IPMI‐
66 HOST2[:PORT],...
67 Specify the remote host(s) to communicate with. Multiple host‐
68 names may be separated by comma or may be specified in a range
69 format; see HOSTRANGED SUPPORT below. An optional port can be
70 specified with each host, which may be useful in port forwarding
71 or similar situations. If specifying an IPv6 address and port,
72 use the format [ADDRESS]:PORT.
73 -u USERNAME, --username=USERNAME
75 Specify the username to use when authenticating with the remote
76 host. If not specified, a null (i.e. anonymous) username is as‐
77 sumed. The user must have atleast USER privileges in order for
78 this tool to operate fully.
79 -p PASSWORD, --password=PASSWORD
81 Specify the password to use when authenticationg with the remote
82 host. If not specified, a null password is assumed. Maximum
83 password length is 16 for IPMI 1.5 and 20 for IPMI 2.0.
84 -P, --password-prompt
86 Prompt for password to avoid possibility of listing it in
87 process lists.
88 -k K_G, --k-g=K_G
90 Specify the K_g BMC key to use when authenticating with the re‐
91 mote host for IPMI 2.0. If not specified, a null key is assumed.
92 To input the key in hexadecimal form, prefix the string with
93 '0x'. E.g., the key 'abc' can be entered with the either the
94 string 'abc' or the string '0x616263'
95 -K, --k-g-prompt
97 Prompt for k-g to avoid possibility of listing it in process
98 lists.
99 --session-timeout=MILLISECONDS
101 Specify the session timeout in milliseconds. Defaults to 20000
102 milliseconds (20 seconds) if not specified.
103 --retransmission-timeout=MILLISECONDS
105 Specify the packet retransmission timeout in milliseconds. De‐
106 faults to 1000 milliseconds (1 second) if not specified. The re‐
107 transmission timeout cannot be larger than the session timeout.
108 -a AUTHENTICATION-TYPE, --authentication-type=AUTHENTICATION-TYPE
110 Specify the IPMI 1.5 authentication type to use. The currently
111 available authentication types are NONE, STRAIGHT_PASSWORD_KEY,
112 MD2, and MD5. Defaults to MD5 if not specified.
113 -I CIPHER-SUITE-ID, --cipher-suite-id=CIPHER-SUITE-ID
115 Specify the IPMI 2.0 cipher suite ID to use. The Cipher Suite ID
116 identifies a set of authentication, integrity, and confidential‐
117 ity algorithms to use for IPMI 2.0 communication. The authenti‐
118 cation algorithm identifies the algorithm to use for session
119 setup, the integrity algorithm identifies the algorithm to use
120 for session packet signatures, and the confidentiality algorithm
121 identifies the algorithm to use for payload encryption. Defaults
122 to cipher suite ID 3 if not specified. The following cipher
123 suite ids are currently supported:
124 0 - Authentication Algorithm = None; Integrity Algorithm = None;
126 Confidentiality Algorithm = None
127 1 - Authentication Algorithm = HMAC-SHA1; Integrity Algorithm =
129 None; Confidentiality Algorithm = None
130 2 - Authentication Algorithm = HMAC-SHA1; Integrity Algorithm =
132 HMAC-SHA1-96; Confidentiality Algorithm = None
133 3 - Authentication Algorithm = HMAC-SHA1; Integrity Algorithm =
135 HMAC-SHA1-96; Confidentiality Algorithm = AES-CBC-128
136 6 - Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
138 None; Confidentiality Algorithm = None
139 7 - Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
141 HMAC-MD5-128; Confidentiality Algorithm = None
142 8 - Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
144 HMAC-MD5-128; Confidentiality Algorithm = AES-CBC-128
145 11 - Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
147 MD5-128; Confidentiality Algorithm = None
148 12 - Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
150 MD5-128; Confidentiality Algorithm = AES-CBC-128
151 15 - Authentication Algorithm = HMAC-SHA256; Integrity Algorithm
153 = None; Confidentiality Algorithm = None
154 16 - Authentication Algorithm = HMAC-SHA256; Integrity Algorithm
156 = HMAC_SHA256_128; Confidentiality Algorithm = None
157 17 - Authentication Algorithm = HMAC-SHA256; Integrity Algorithm
159 = HMAC_SHA256_128; Confidentiality Algorithm = AES-CBC-128
160 -l PRIVILEGE-LEVEL, --privilege-level=PRIVILEGE-LEVEL
162 Specify the privilege level to be used. The currently available
163 privilege levels are USER, OPERATOR, and ADMIN. Defaults to OP‐
164 ERATOR if not specified.
165 --config-file=FILE
167 Specify an alternate configuration file.
168 -W WORKAROUNDS, --workaround-flags=WORKAROUNDS
170 Specify workarounds to vendor compliance issues. Multiple work‐
171 arounds can be specified separated by commas. A special command
172 line flag of "none", will indicate no workarounds (may be useful
173 for overriding configured defaults). See WORKAROUNDS below for a
174 list of available workarounds.
175 --debug
177 Turn on debugging.
178 -?, --help
180 Output a help list and exit.
181 --usage
183 Output a usage message and exit.
184 -V, --version
186 Output the program version and exit.
187
189 The following options are specific to ipmiseld.
190 -v Log verbose information. This option will log additional infor‐
192 mation. Most notably it will output additional hex codes to
193 given information on ambiguous SEL entries or SEL records. For
194 example, it will output Generator ID hex codes for sensors with‐
195 out names. Additional non-critical SEL errors or issues will
196 also be logged. Somewhat common errors, such as timeouts or in‐
197 valid hostnames, will output with increased verbosity.
198 -t SENSOR-TYPE-LIST, --sensor-types=SENSOR-TYPE-LIST
200 Specify sensor types of SEL events to log. By default, all sen‐
201 sor types are logged. A special command line type of "all", will
202 indicate all types should be shown (may be useful for overriding
203 configured defaults). Multiple types can be separated by commas
204 or spaces. Users may specify sensor types by string (see
205 --list-sensor-types in ipmi-sel(8)) or by number (decimal or
206 hex).
207 -T SENSOR-TYPE-LIST, --exclude-sensor-types=SENSOR-TYPE-LIST
209 Specify sensor types of SEL events to not log. By default, no
210 sensor types are filtered. A special command line type of
211 "none", will indicate no types should be excluded (may be useful
212 for overriding configured defaults). Multiple types can be sepa‐
213 rated by commas or spaces. Users may specify sensor types by
214 string (see --list-sensor-types in ipmi-sel(8)) or by number
215 (decimal or hex).
216 --system-event-only
218 Log only system event records (i.e. don't log OEM records).
219 --oem-event-only
221 Log only OEM event records (i.e. don't log system event
222 records).
223 --event-state-config-file=FILE
225 Specify an alternate event state configuration file.
226 --interpret-oem-data
228 Attempt to interpret OEM data, such as event data, sensor read‐
229 ings, or general extra info, etc. If an OEM interpretation is
230 not available, the default output will be generated. Correctness
231 of OEM interpretations cannot be guaranteed due to potential
232 changes OEM vendors may make in products, firmware, etc. See OEM
233 INTERPRETATION below for confirmed supported motherboard inter‐
234 pretations.
235 --entity-sensor-names
237 Output sensor names prefixed with their entity id and instance
238 number when appropriate. This may be necessary on some mother‐
239 boards to help identify what sensors are referencing. For exam‐
240 ple, a motherboard may have multiple sensors named 'TEMP'. The
241 entity id and instance number may help clarify which sensor
242 refers to "Processor 1" vs. "Processor 2".
243 --non-abbreviated-units
245 Output non-abbreviated units (e.g. 'Amps' instead of 'A'). May
246 aid in disambiguation of units (e.g. 'C' for Celsius or
247 Coulombs).
248 --event-state-filter=FILTERSTRING
250 Specify event states to be filtered out and not logged. Possible
251 inputs are NOMINAL, WARNING, CRITICAL, and NA. Multiple states
252 can be listed separated by comma. The special case string of
253 "none" will indicate no event states should be excluded (may be
254 useful for overriding configured defaults).
255 --warning-threshold=PERCENTINT
257 Specify SEL fullness warning threshold as an integer percentage.
258 When the SEL is past this percentage full, a warning will be
259 output indicating that SEL is nearly full. Specify 0 to disable
260 warning logs. Defaults to 80.
261 --clear-threshold=PERCENTINT
263 Specify SEL fullness clear threshold as an integer percentage.
264 When the SEL is past this percentage full, ipmiseld will attempt
265 to clear the SEL. Specify 0 to disable clearing. When the SEL is
266 full, it will be the responsibility of the user to clear the SEL
267 manually if clearing is disabled. Defaults to 0. If specified to
268 a non-zero value, be careful that the clearing of the SEL could
269 affect other applications that monitor the SEL, such as monitor‐
270 ing applications that use ipmi-sel(8) or libipmimonitoring(3).
271 --system-event-format=FORMATSTRING
273 Specify the format of the log output when a SEL system event is
274 encountered. Defaults to "SEL System Event: %d, %t, %s, %I, %E"
275 if logging locally, "SEL System Event(%h): %d, %t, %s, %I, %E"
276 if logging outofband or with hostranges. See SEL LOG FORMAT
277 STRING below for formatting details.
278 --oem-timestamped-event-format=FORMATSTRING
280 Specify the format of the log output when a SEL OEM timestamped
281 event is encountered. Defaults to "SEL OEM Event: %d, %t, %I,
282 %o" if logging locally, "SEL OEM Event(%h): %d, %t, %I, %o" if
283 logging outofband or with hostranges.. See SEL LOG FORMAT STRING
284 below for formatting details.
285 --oem-non-timestamped-event-format=FORMATSTRING
287 Specify the format of the log output when a SEL OEM non-times‐
288 tamped event is encountered. Defaults to "SEL OEM Event: %I, %o"
289 if logging locally, "SEL OEM Event(%h): %I, %o" if logging out‐
290 ofband or with hostranges.. See SEL LOG FORMAT STRING below for
291 formatting details.
292 --poll-interval=SECONDS
294 Specify the poll interval to check the SEL for new events. De‐
295 faults to 300 seconds (i.e. 5 minutes).
296 --log-facility=STRING
298 Specify the log facility to use. Defaults to LOG_DAEMON. Legal
299 inputs are LOG_DAEMON, LOG_USER, LOG_LOCAL0, LOG_LOCAL1, LOG_LO‐
300 CAL2, LOG_LOCAL3, LOG_LOCAL4, LOG_LOCAL5, LOG_LOCAL6, LOG_LO‐
301 CAL7.
302 --log-priority=STRING
304 Specify the log priority to use. Defaults to LOG_ERR. Legal in‐
305 puts are LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR, LOG_WARNING,
306 LOG_NOTICE, LOG_INFO, LOG_DEBUG.
307 --cache-directory=DIRECTORY
309 Specify an alternate cache directory location for ipmiseld to
310 use. The cache directory will be used to cache a wide variety of
311 data, including the SDR and recent logging information to ensure
312 log entries are not missed on reboots and other system failures.
313 --ignore-sdr
315 Ignore SDR related processing. May lead to incomplete or less
316 useful information being output, however it will allow function‐
317 ality for systems without SDRs or when the correct SDR cannot be
318 loaded.
319 --re-download-sdr
321 Re-download the SDR on start even if it is not out of date. This
322 may help work around systems that do not properly timestamp SDR
323 modification times.
324 --clear-sel
326 On startup, clear any SEL being monitored. May be useful the
327 first time running ipmiseld to avoid warning messages or SEL
328 clears until a long time in the future.
329 --threadpool-count=NUM
331 Specify the number of threads for parallel SEL polling. This op‐
332 tion is very similar to the --fanout option in ipmi-sel(8) but
333 the threads are created only once on initialization for faster
334 processing. Defaults to 8, however the threadpool count will al‐
335 ways be decreased if the number of nodes specified is less than
336 the number of threads.
337 --test-run
339 Do not daemonize, output the current SEL of configured hosts as
340 a test of current settings and configuration. SEL entries will
341 be output to stdout instead of syslog.
342 --foreground
344 Run daemon in the foreground. SEL entries will be output to std‐
345 out instead of syslog.
346
348 The output format of log messages can be adjusted via the --sys‐
349 tem-event-format, --oem-timestamped-event-format and --oem-non-times‐
350 tamped-event-format options. Options such as --interpret-oem-data,
351 --entity-sensor-names, and --non-abbreviated-units can further adjust
352 the output format. The following conversion directives will allow the
353 user to output specifics of each SEL event that occurs.
354 For System, OEM timestamped, and OEM non-timestamped events
356 %h - target host, useful if logging from multiple hosts
358 %i - record ID in decimal
360 %I - event state interpretation (NOMINAL, WARNING, or CRITICAL)
362 For System and OEM timestamped events
364 %t - time in format H:M:S using 24 hour clock
366 %d - date in format D-M-YEAR
368 For System events
370 %T - sensor type
372 %s - sensor name
374 %e - event data 1 string
376 %f - event data 2 string [2]
378 %h - event data 3 string
380 %c - combined event data 2 and event data 3 string
382 %p - event data 2 previous state string
384 %S - event data 2 severity string
386 %E - combined event data 1, 2, and 3 string
388 %k - event direction
390 For OEM timestamped events
392 %m - manufacturer id
394 For OEM timestamped and OEM non-timestamped events
396 %o - oem data in hex
398 %O - OEM supplied string describing the event (depends on manufacturer)
400
402 Multiple hosts can be input either as an explicit comma separated lists
403 of hosts or a range of hostnames in the general form: prefix[n-m,l-
404 k,...], where n < m and l < k, etc. The later form should not be con‐
405 fused with regular expression character classes (also denoted by []).
406 For example, foo[19] does not represent foo1 or foo9, but rather repre‐
407 sents a degenerate range: foo19.
408 This range syntax is meant only as a convenience on clusters with a
410 prefixNN naming convention and specification of ranges should not be
411 considered necessary -- the list foo1,foo9 could be specified as such,
412 or by the range foo[1,9].
413 Some examples of range usage follow:
415 foo[01-05] instead of foo01,foo02,foo03,foo04,foo05
416 foo[7,9-10] instead of foo7,foo9,foo10
417 foo[0-3] instead of foo0,foo1,foo2,foo3
418 As a reminder to the reader, some shells will interpret brackets ([ and
420 ]) for pattern matching. Depending on your shell, it may be necessary
421 to enclose ranged lists within quotes.
422 In-band IPMI Communication will be used when the host "localhost" is
424 specified. This allows the user to add the localhost into the hos‐
425 tranged output.
426
428 Most often, IPMI problems are due to configuration problems.
429 IPMI over LAN problems involve a misconfiguration of the remote ma‐
431 chine's BMC. Double check to make sure the following are configured
432 properly in the remote machine's BMC: IP address, MAC address, subnet
433 mask, username, user enablement, user privilege, password, LAN privi‐
434 lege, LAN enablement, and allowed authentication type(s). For IPMI 2.0
435 connections, double check to make sure the cipher suite privilege(s)
436 and K_g key are configured properly. The ipmi-config(8) tool can be
437 used to check and/or change these configuration settings.
438 Inband IPMI problems are typically caused by improperly configured
440 drivers or non-standard BMCs.
441 In addition to the troubleshooting tips below, please see WORKAROUNDS
443 below to also if there are any vendor specific bugs that have been dis‐
444 covered and worked around.
445 Listed below are many of the common issues for error messages. For ad‐
447 ditional support, please e-mail the <freeipmi-users@gnu.org> mailing
448 list.
449 "username invalid" - The username entered (or a NULL username if none
451 was entered) is not available on the remote machine. It may also be
452 possible the remote BMC's username configuration is incorrect.
453 "password invalid" - The password entered (or a NULL password if none
455 was entered) is not correct. It may also be possible the password for
456 the user is not correctly configured on the remote BMC.
457 "password verification timeout" - Password verification has timed out.
459 A "password invalid" error (described above) or a generic "session
460 timeout" (described below) occurred. During this point in the protocol
461 it cannot be differentiated which occurred.
462 "k_g invalid" - The K_g key entered (or a NULL K_g key if none was en‐
464 tered) is not correct. It may also be possible the K_g key is not cor‐
465 rectly configured on the remote BMC.
466 "privilege level insufficient" - An IPMI command requires a higher user
468 privilege than the one authenticated with. Please try to authenticate
469 with a higher privilege. This may require authenticating to a different
470 user which has a higher maximum privilege.
471 "privilege level cannot be obtained for this user" - The privilege
473 level you are attempting to authenticate with is higher than the maxi‐
474 mum allowed for this user. Please try again with a lower privilege. It
475 may also be possible the maximum privilege level allowed for a user is
476 not configured properly on the remote BMC.
477 "authentication type unavailable for attempted privilege level" - The
479 authentication type you wish to authenticate with is not available for
480 this privilege level. Please try again with an alternate authentication
481 type or alternate privilege level. It may also be possible the avail‐
482 able authentication types you can authenticate with are not correctly
483 configured on the remote BMC.
484 "cipher suite id unavailable" - The cipher suite id you wish to authen‐
486 ticate with is not available on the remote BMC. Please try again with
487 an alternate cipher suite id. It may also be possible the available ci‐
488 pher suite ids are not correctly configured on the remote BMC.
489 "ipmi 2.0 unavailable" - IPMI 2.0 was not discovered on the remote ma‐
491 chine. Please try to use IPMI 1.5 instead.
492 "connection timeout" - Initial IPMI communication failed. A number of
494 potential errors are possible, including an invalid hostname specified,
495 an IPMI IP address cannot be resolved, IPMI is not enabled on the re‐
496 mote server, the network connection is bad, etc. Please verify configu‐
497 ration and connectivity.
498 "session timeout" - The IPMI session has timed out. Please reconnect.
500 If this error occurs often, you may wish to increase the retransmission
501 timeout. Some remote BMCs are considerably slower than others.
502 "device not found" - The specified device could not be found. Please
504 check configuration or inputs and try again.
505 "driver timeout" - Communication with the driver or device has timed
507 out. Please try again.
508 "message timeout" - Communication with the driver or device has timed
510 out. Please try again.
511 "BMC busy" - The BMC is currently busy. It may be processing informa‐
513 tion or have too many simultaneous sessions to manage. Please wait and
514 try again.
515 "could not find inband device" - An inband device could not be found.
517 Please check configuration or specify specific device or driver on the
518 command line.
519 "driver timeout" - The inband driver has timed out communicating to the
521 local BMC or service processor. The BMC or service processor may be
522 busy or (worst case) possibly non-functioning.
523 "internal IPMI error" - An IPMI error has occurred that FreeIPMI does
525 not know how to handle. Please e-mail <freeipmi-users@gnu.org> to re‐
526 port the issue.
527
529 Some timestamps in the SEL may report a date of 1-Jan-1970, the epoch
530 for SEL timestamps. This timestamp is not necessarily incorrect. It
531 usually indicates a hardware event that occurred before a timestamp in
532 firmware has been initialized. For example, certain hardware components
533 will have their internal clocks reset during a power cycle.
534 However, if the internal clock of the SEL appears to be regularly in‐
536 correct, you may need to set the SEL time. This can be done using bmc-
537 device(8).
538 The following are common SEL related messages.
540 "sel config file parse error" - A parse error was found in the sel
542 event interpretation configuration file. Please see freeipmi_inter‐
543 pret_sel.conf(5).
544
546 With so many different vendors implementing their own IPMI solutions,
547 different vendors may implement their IPMI protocols incorrectly. The
548 following describes a number of workarounds currently available to han‐
549 dle discovered compliance issues. When possible, workarounds have been
550 implemented so they will be transparent to the user. However, some will
551 require the user to specify a workaround be used via the -W option.
552 The hardware listed below may only indicate the hardware that a problem
554 was discovered on. Newer versions of hardware may fix the problems in‐
555 dicated below. Similar machines from vendors may or may not exhibit the
556 same problems. Different vendors may license their firmware from the
557 same IPMI firmware developer, so it may be worthwhile to try work‐
558 arounds listed below even if your motherboard is not listed.
559 If you believe your hardware has an additional compliance issue that
561 needs a workaround to be implemented, please contact the FreeIPMI main‐
562 tainers on <freeipmi-users@gnu.org> or <freeipmi-devel@gnu.org>.
563 assumeio - This workaround flag will assume inband interfaces communi‐
565 cate with system I/O rather than being memory-mapped. This will work
566 around systems that report invalid base addresses. Those hitting this
567 issue may see "device not supported" or "could not find inband device"
568 errors. Issue observed on HP ProLiant DL145 G1.
569 spinpoll - This workaround flag will inform some inband drivers (most
571 notably the KCS driver) to spin while polling rather than putting the
572 process to sleep. This may significantly improve the wall clock running
573 time of tools because an operating system scheduler's granularity may
574 be much larger than the time it takes to perform a single IPMI message
575 transaction. However, by spinning, your system may be performing less
576 useful work by not contexting out the tool for a more useful task.
577 authcap - This workaround flag will skip early checks for username ca‐
579 pabilities, authentication capabilities, and K_g support and allow IPMI
580 authentication to succeed. It works around multiple issues in which the
581 remote system does not properly report username capabilities, authenti‐
582 cation capabilities, or K_g status. Those hitting this issue may see
583 "username invalid", "authentication type unavailable for attempted
584 privilege level", or "k_g invalid" errors. Issue observed on Asus
585 P5M2/P5MT-R/RS162-E4/RX4, Intel SR1520ML/X38ML, and Sun Fire
586 2200/4150/4450 with ELOM.
587 nochecksumcheck - This workaround flag will tell FreeIPMI to not check
589 the checksums returned from IPMI command responses. It works around
590 systems that return invalid checksums due to implementation errors, but
591 the packet is otherwise valid. Users are cautioned on the use of this
592 option, as it removes validation of packet integrity in a number of
593 circumstances. However, it is unlikely to be an issue in most situa‐
594 tions. Those hitting this issue may see "connection timeout", "session
595 timeout", or "password verification timeout" errors. On IPMI 1.5 con‐
596 nections, the "noauthcodecheck" workaround may also needed too. Issue
597 observed on Supermicro X9SCM-iiF, Supermicro X9DRi-F, and Supermicro
598 X9DRFR.
599 idzero - This workaround flag will allow empty session IDs to be ac‐
601 cepted by the client. It works around IPMI sessions that report empty
602 session IDs to the client. Those hitting this issue may see "session
603 timeout" errors. Issue observed on Tyan S2882 with M3289 BMC.
604 unexpectedauth - This workaround flag will allow unexpected non-null
606 authcodes to be checked as though they were expected. It works around
607 an issue when packets contain non-null authentication data when they
608 should be null due to disabled per-message authentication. Those hit‐
609 ting this issue may see "session timeout" errors. Issue observed on
610 Dell PowerEdge 2850,SC1425. Confirmed fixed on newer firmware.
611 forcepermsg - This workaround flag will force per-message authentica‐
613 tion to be used no matter what is advertised by the remote system. It
614 works around an issue when per-message authentication is advertised as
615 disabled on the remote system, but it is actually required for the pro‐
616 tocol. Those hitting this issue may see "session timeout" errors. Is‐
617 sue observed on IBM eServer 325.
618 endianseq - This workaround flag will flip the endian of the session
620 sequence numbers to allow the session to continue properly. It works
621 around IPMI 1.5 session sequence numbers that are the wrong endian.
622 Those hitting this issue may see "session timeout" errors. Issue ob‐
623 served on some Sun ILOM 1.0/2.0 (depends on service processor endian).
624 noauthcodecheck - This workaround flag will tell FreeIPMI to not check
626 the authentication codes returned from IPMI 1.5 command responses. It
627 works around systems that return invalid authentication codes due to
628 hashing or implementation errors. Users are cautioned on the use of
629 this option, as it removes an authentication check verifying the valid‐
630 ity of a packet. However, in most organizations, this is unlikely to be
631 a security issue. Those hitting this issue may see "connection time‐
632 out", "session timeout", or "password verification timeout" errors.
633 Issue observed on Xyratex FB-H8-SRAY, Intel Windmill, Quanta Winter‐
634 fell, and Wiwynn Windmill.
635 intel20 - This workaround flag will work around several Intel IPMI 2.0
637 authentication issues. The issues covered include padding of usernames,
638 and password truncation if the authentication algorithm is HMAC-
639 MD5-128. Those hitting this issue may see "username invalid", "password
640 invalid", or "k_g invalid" errors. Issue observed on Intel SE7520AF2
641 with Intel Server Management Module (Professional Edition).
642 supermicro20 - This workaround flag will work around several Supermicro
644 IPMI 2.0 authentication issues on motherboards w/ Peppercon IPMI
645 firmware. The issues covered include handling invalid length authenti‐
646 cation codes. Those hitting this issue may see "password invalid" er‐
647 rors. Issue observed on Supermicro H8QME with SIMSO daughter card.
648 Confirmed fixed on newerver firmware.
649 sun20 - This workaround flag will work work around several Sun IPMI 2.0
651 authentication issues. The issues covered include invalid lengthed hash
652 keys, improperly hashed keys, and invalid cipher suite records. Those
653 hitting this issue may see "password invalid" or "bmc error" errors.
654 Issue observed on Sun Fire 4100/4200/4500 with ILOM. This workaround
655 automatically includes the "opensesspriv" workaround.
656 opensesspriv - This workaround flag will slightly alter FreeIPMI's IPMI
658 2.0 connection protocol to workaround an invalid hashing algorithm used
659 by the remote system. The privilege level sent during the Open Session
660 stage of an IPMI 2.0 connection is used for hashing keys instead of the
661 privilege level sent during the RAKP1 connection stage. Those hitting
662 this issue may see "password invalid", "k_g invalid", or "bad rmcpplus
663 status code" errors. Issue observed on Sun Fire 4100/4200/4500 with
664 ILOM, Inventec 5441/Dell Xanadu II, Supermicro X8DTH, Supermicro X8DTG,
665 Intel S5500WBV/Penguin Relion 700, Intel S2600JF/Appro 512X, Quanta
666 QSSC-S4R/Appro GB812X-CN, and Dell C5220. This workaround is automati‐
667 cally triggered with the "sun20" workaround.
668 integritycheckvalue - This workaround flag will work around an invalid
670 integrity check value during an IPMI 2.0 session establishment when us‐
671 ing Cipher Suite ID 0. The integrity check value should be 0 length,
672 however the remote motherboard responds with a non-empty field. Those
673 hitting this issue may see "k_g invalid" errors. Issue observed on Su‐
674 permicro X8DTG, Supermicro X8DTU, and Intel S5500WBV/Penguin Relion
675 700, and Intel S2600JF/Appro 512X.
676 assumesystemevent - This workaround option will assume invalid SEL
678 record types are system event records. Records may be formatted cor‐
679 rectly but report invalid record types. Those hitting this issue may
680 see "Unknown SEL Record Type" errors. Output may be unknown, pray for
681 the best. This option is confirmed to work around compliances issues on
682 HP DL 380 G5 motherboards.
683 No IPMI 1.5 Support - Some motherboards that support IPMI 2.0 have been
685 found to not support IPMI 1.5. Those hitting this issue may see "ipmi
686 2.0 unavailable" or "connection timeout" errors. This issue can be
687 worked around by using IPMI 2.0 instead of IPMI 1.5 by specifying
688 --driver-type=LAN_2_0. Issue observed on a number of HP and Supermicro
689 motherboards.
690
692 The following motherboards are confirmed to have atleast some support
693 by the --interpret-oem-data option. While highly probable the OEM data
694 interpretations would work across other motherboards by the same manu‐
695 facturer, there are no guarantees. Some of the motherboards below may
696 be rebranded by vendors/distributors.

712 On older operating systems, if you input your username, password, and
713 other potentially security relevant information on the command line,
714 this information may be discovered by other users when using tools like
715 the ps(1) command or looking in the /proc file system. It is generally
716 more secure to input password information with options like the -P or
717 -K options. Configuring security relevant information in the FreeIPMI
718 configuration file would also be an appropriate way to hide this infor‐
719 mation.
720 In order to prevent brute force attacks, some BMCs will temporarily
722 "lock up" after a number of remote authentication errors. You may need
723 to wait awhile in order to this temporary "lock up" to pass before you
724 may authenticate again.
