SYNOPSIS

9       bmc-config [OPTION...]
10

DESCRIPTION

12       Bmc-config is used to get and set BMC configuration parameters, such as
13       usernames, passwords, networking information, security, Serial-over-LAN
14       (SOL),  and  other  core  IPMI  fields.  This configuration is required
15       before most IPMI tools can be used to access a machine remotely.
16
17       The majority of configuration operations require ADMIN  privilege  when
18       using bmc-config out-of-band. Although connecting via a user with ADMIN
19       privileges is not required for out-of-band use, the  vast  majority  of
20       configuration options will not be retrieved or set.
21
22       For  configuration  of chassis, platform event filtering (PEF), or sen‐
23       sors, please see  the  ipmi-chassis-config(8),  ipmi-pef-config(8),  or
24       ipmi-sensors-config(8)  tools  respectively. For some OEM specific con‐
25       figurations, please see ipmi-oem(8).
26
27       Listed below are general IPMI options, tool specific  options,  trouble
28       shooting  information,  workaround  information,  examples,  and  known
29       issues. For a general introduction to FreeIPMI please see  freeipmi(7).
30       See  GENERAL  USE  below for a description on how most will want to use
31       Bmc-config.

GENERAL OPTIONS

34       The following options are general options for configuring IPMI communi‐
35       cation and executing general tool commands.
36
37       -D, --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,  and
42              SUNBMC.
43
44       --disable-auto-probe
45              Do not probe in-band IPMI devices for default settings.
46
47       --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
52       --driver-device=DEVICE
53              Specify the in-band driver device path to be used instead of the
54              probed path.
55
56       --register-spacing=REGISTER-SPACING
57              Specify the in-band  driver  register  spacing  instead  of  the
58              probed value.
59
60       -h, --hostname=IPMIHOST1,IPMIHOST2,...
61              Specify  the  remote host(s) to communicate with. Multiple host‐
62              names may be separated by comma or may be specified in  a  range
63              format; see HOSTRANGED SUPPORT below.
64
65       -u, --username=USERNAME
66              Specify  the username to use when authenticating with the remote
67              host.  If not specified, a null  (i.e.  anonymous)  username  is
68              assumed.  The  user  must have atleast ADMIN privileges in order
69              for this tool to operate fully.
70
71       -p, --password=PASSWORD
72              Specify the password to use when authenticationg with the remote
73              host.   If  not  specified,  a null password is assumed. Maximum
74              password length is 16 for IPMI 1.5 and 20 for IPMI 2.0.
75
76       -P, --password-prompt
77              Prompt for password  to  avoid  possibility  of  listing  it  in
78              process lists.
79
80       -k, --k-g=K_G
81              Specify  the  K_g  BMC  key  to use when authenticating with the
82              remote host for IPMI 2.0.  If  not  specified,  a  null  key  is
83              assumed. To input the key in hexadecimal form, prefix the string
84              with '0x'. E.g., the key 'abc' can be entered  with  the  either
85              the string 'abc' or the string '0x616263'
86
87       -K, --k-g-prompt
88              Prompt  for  k-g  to  avoid possibility of listing it in process
89              lists.
90
91       --session-timeout=MILLISECONDS
92              Specify the session timeout in milliseconds. Defaults  to  20000
93              milliseconds (20 seconds) if not specified.
94
95       --retransmission-timeout=MILLISECONDS
96              Specify  the  packet  retransmission  timeout  in  milliseconds.
97              Defaults to 1000 milliseconds (1 second) if not  specified.  The
98              retransmission  timeout  cannot be larger than the session time‐
99              out.
100
101       -a, --authentication-type=AUTHENTICATION-TYPE
102              Specify the IPMI 1.5 authentication type to use.  The  currently
103              available  authentication types are NONE, STRAIGHT_PASSWORD_KEY,
104              MD2, and MD5. Defaults to MD5 if not specified.
105
106       -I, --cipher-suite-id=CIPHER-SUITE-ID
107              Specify the IPMI 2.0 cipher suite ID to use. The Cipher Suite ID
108              identifies a set of authentication, integrity, and confidential‐
109              ity algorithms to use for IPMI 2.0 communication. The  authenti‐
110              cation  algorithm  identifies  the  algorithm to use for session
111              setup, the integrity algorithm identifies the algorithm  to  use
112              for session packet signatures, and the confidentiality algorithm
113              identifies the algorithm to use for payload encryption. Defaults
114              to  cipher  suite  ID  3  if not specified. The following cipher
115              suite ids are currently supported:
116
117              0 - Authentication Algorithm = None; Integrity Algorithm = None;
118              Confidentiality Algorithm = None
119

121              None; Confidentiality Algorithm = None
122
123              2 - Authentication Algorithm = HMAC-SHA1; Integrity Algorithm  =
124              HMAC-SHA1-96; Confidentiality Algorithm = None
125
126              3  - Authentication Algorithm = HMAC-SHA1; Integrity Algorithm =
127              HMAC-SHA1-96; Confidentiality Algorithm = AES-CBC-128
128
129              6 - Authentication Algorithm = HMAC-MD5; Integrity  Algorithm  =
130              None; Confidentiality Algorithm = None
131
132              7  -  Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
133              HMAC-MD5-128; Confidentiality Algorithm = None
134
135              8 - Authentication Algorithm = HMAC-MD5; Integrity  Algorithm  =
136              HMAC-MD5-128; Confidentiality Algorithm = AES-CBC-128
137
138              11  - Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
139              MD5-128; Confidentiality Algorithm = None
140
141              12 - Authentication Algorithm = HMAC-MD5; Integrity Algorithm  =
142              MD5-128; Confidentiality Algorithm = AES-CBC-128
143
144       -l, --privilege-level=PRIVILEGE-LEVEL
145              Specify  the privilege level to be used. The currently available
146              privilege levels are USER,  OPERATOR,  and  ADMIN.  Defaults  to
147              ADMIN if not specified.
148
149       --config-file=FILE
150              Specify an alternate configuration file.
151
152       -W, --workaround-flags=WORKAROUNDS
153              Specify  workarounds to vendor compliance issues. Multiple work‐
154              arounds can be specified separated by  commas.  See  WORKAROUNDS
155              below for a list of available workarounds.
156
157       --debug
158              Turn on debugging.
159
160       -?, --help
161              Output a help list and exit.
162

165
166       -V, --version
167              Output the program version and exit.
168

CONFIG OPTIONS

170       The  following options are used to read, write, and find differences in
171       configuration values.
172
173       -o, --checkout
174              Fetch configuration information.
175
176       -c, --commit
177              Update configuration information  from  a  config  file  or  key
178              pairs.
179
180       -d, --diff
181              Show differences between stored information and a config file or
182              key pairs.
183
184       -n FILENAME, --filename=FILENAME
185              Specify a config file for checkout/commit/diff.
186
187       -e "KEY=VALUE", --key-pair="KEY=VALUE"
188              Specify KEY=VALUE pairs for checkout/commit/diff. Specify KEY by
189              SectionName:FieldName.  This  option can be used multiple times.
190              On commit, any KEY=VALUE pairs will overwrite any  pairs  speci‐
191              fied in a file with --filename.
192
193       -S "SECTION", --section="SECTION"
194              Specify a SECTION for checkout. This option can be used multiple
195              times.
196
197       -L, --listsections
198              List available sections for checkout.
199
200       -v, --verbose
201              Output additional detailed information. In general  will  output
202              more  detailed  information  about what fields can and cannot be
203              checked out, committed, etc. When used  with  --checkout,  addi‐
204              tional  uncommon,  unconfigurable,  and/or  unused fields may be
205              output.
206

HOSTRANGED OPTIONS

208       The following options manipulate hostranged output. See HOSTRANGED SUP‐
209       PORT below for additional information on hostranges.
210
211       -B, --buffer-output
212              Buffer  hostranged output. For each node, buffer standard output
213              until the node has completed its IPMI operation. When specifying
214              this  option, data may appear to output slower to the user since
215              the the entire IPMI operation must complete before any data  can
216              be output.  See HOSTRANGED SUPPORT below for additional informa‐
217              tion.
218
219       -C, --consolidate-output
220              Consolidate hostranged output. The complete standard output from
221              every  node  specified  will  be consolidated so that nodes with
222              identical output are not output twice. A header will list  those
223              nodes  with  the consolidated output. When this option is speci‐
224              fied, no output can be seen until the  IPMI  operations  to  all
225              nodes  has  completed.  If  the  user  breaks out of the program
226              early, all currently consolidated output  will  be  dumped.  See
227              HOSTRANGED SUPPORT below for additional information.
228
229       -F, --fanout
230              Specify  multiple  host  fanout.  A "sliding window" (or fanout)
231              algorithm is used for parallel IPMI communication so that slower
232              nodes or timed out nodes will not impede parallel communication.
233              The maximum number of threads available at the same time is lim‐
234              ited by the fanout. The default is 64.
235
236       -E, --eliminate
237              Eliminate  hosts  determined  as undetected by ipmidetect.  This
238              attempts to remove the common issue of hostranged execution tim‐
239              ing  out  due  to  several nodes being removed from service in a
240              large cluster. The ipmidetectd daemon must  be  running  on  the
241              node executing the command.
242
243       --always-prefix
244              Always prefix output, even if only one host is specified or com‐
245              municating in-band. This option is primarily useful for  script‐
246              ing  purposes.  Option  will be ignored if specified with the -C
247              option.
248

GENERAL USE

250       Most users of will want to:
251
252       A) Run with --checkout to get a copy of the current  configuration  and
253       store  it in a file. The standard output can be redirected to a file or
254       a file can be specified with the --filename option.
255
256       B) Edit the configuration file with an editor.
257
258       C) Commit the configuration back using the --commit option and specify‐
259       ing  the  configuration file with the --filename option. The configura‐
260       tion can be committed to multiple hosts in parallel via  the  hostrange
261       support.
262
263       Although not typically necessarily, some motherboards do not store con‐
264       figuration values  in  non-volatile  memory.  Therefore,  after  system
265       reboots,  some configuration values may have changed. The user may wish
266       to run configuration tools on each boot to ensure configuration  values
267       remain.
268
269       Comments  throughout the checked out file will give instructions on how
270       to configure the fields.  The bmc-config.conf(5)  also  provides  addi‐
271       tional information on the meaning of different fields.
272
273       For users with large clusters or sets of nodes, you may wish to use the
274       same configuration file for all nodes. The one  problem  with  this  is
275       that  the  IP address and MAC address will be different on each node in
276       your cluster and thus can't be configured through the same config file.
277       The  IP  address and MAC address in your config file may be overwritten
278       on the command line using  --key-pair  option.  The  following  example
279       could  be used in a script to configure each node in a cluster with the
280       same BMC config file. The script only needs to determine the correct IP
281       address and MAC address to use.
282
283       #     bmc-config     --commit    -k    Lan_Conf:Ip_Address=$MY_IP    -k
284       Lan_Conf:Mac_Address=$MY_MAC -n my_bmc.conf
285

BMC-CONFIG SPECIAL CASE CONFIGURATION INFORMATION

287       The UserN:Password fields (where N is a number) cannot be  checked  out
288       on  some systems, therefore the checked out value will always be blank.
289       The UserN:Enable_User field (where N is a number) cannot be checked out
290       on older IPMI systems, therefore the checked out value will sometime be
291       blank.   The  UserN:Lan_Session_Limit  and   UserN:Serial_Session_Limit
292       fields  (where  N  is  a number) cannot be checked out on some systems,
293       therefore the checked out value will always be blank. If not  specified
294       in  later commits of configurations, the field may be reset to 0 due to
295       a requirement that other fields  (configured  along  with  the  session
296       limit)  will  require an input value for the session limit.  Under most
297       conditions, it is not necessary to set this field and  most  users  may
298       choose  to  ignore  it. This field is considered optional by IPMI stan‐
299       dards, and may result in errors when attempting to configure  it  to  a
300       non-zero  value. If errors to occur, setting the value back to 0 should
301       resolve    problems.     The     fields     Lan_Conf:IP_Address     and
302       Lan_Conf:MAC_Address cannot be committed in parallel via hostrange sup‐
303       port. Each machine must be configured with a unique IP Address and  MAC
304       Address  tuple, therefore we disallow this configuration in bmc-config.
305       On some motherboards, Lan_Conf:MAC_Address may be read only and the MAC
306       address   is   automatically   configured.    On   some   motherboards,
307       Lan_Conf:MAC_Address may be read only and the MAC address is configured
308       via  an  OEM  command.  See ipmi-oem(8) to see if OEM configuration for
309       your motherboard is supported.  On some motherboards, a number of  user
310       configuration  fields  cannot  be read or configured until after a non-
311       null username or non-null password is  configured.  In  some  of  these
312       cases, an appropriate output in the config file will indicate this sit‐
313       uation. However, not all motherboard  corner  cases  may  be  detected.
314       Users  may  wish  to  play  around  with the ordering of fields to work
315       around these problems.  On some  motherboards,  OEM  Authentication  in
316       Lan_Conf_Auth  cannot be enabled. However, the default motherboard set‐
317       tings have these fields enabled. Users are advised to disable  all  OEM
318       Authentication in this section.
319

HOSTRANGED SUPPORT

321       Multiple hosts can be input either as an explicit comma separated lists
322       of hosts or a range of hostnames in  the  general  form:  prefix[n-m,l-
323       k,...],  where  n < m and l < k, etc. The later form should not be con‐
324       fused with regular expression character classes (also denoted  by  []).
325       For example, foo[19] does not represent foo1 or foo9, but rather repre‐
326       sents a degenerate range: foo19.
327
328       This range syntax is meant only as a convenience  on  clusters  with  a
329       prefixNN  naming  convention  and specification of ranges should not be
330       considered necessary -- the list foo1,foo9 could be specified as  such,
331       or by the range foo[1,9].
332
333       Some examples of range usage follow:
334           foo[01-05] instead of foo01,foo02,foo03,foo04,foo05
335           foo[7,9-10] instead of foo7,foo9,foo10
336           foo[0-3] instead of foo0,foo1,foo2,foo3
337
338       As a reminder to the reader, some shells will interpret brackets ([ and
339       ]) for pattern matching. Depending on your shell, it may  be  necessary
340       to enclose ranged lists within quotes.
341
342       When  multiple  hosts  are specified by the user, a thread will be exe‐
343       cuted for each host in parallel up to the configured fanout (which  can
344       be  adjusted via the -F option). This will allow communication to large
345       numbers of nodes far more quickly than if done in serial.
346
347       By default, standard output from each node  specified  will  be  output
348       with the hostname prepended to each line. Although this output is read‐
349       able in many situations, it may be difficult to read  in  other  situa‐
350       tions.  For  example, output from multiple nodes may be mixed together.
351       The -B and -C options can be used to change this default.
352
353       In-band IPMI Communication will be used when the  host  "localhost"  is
354       specified.  This  allows  the  user  to add the localhost into the hos‐
355       tranged output.
356

GENERAL TROUBLESHOOTING

358       Most often, IPMI problems are due  to  configuration  problems.  Inband
359       IPMI  problems are typically caused by improperly configured drivers or
360       non-standard BMCs. IPMI over LAN problems involve a misconfiguration of
361       the  remote machine's BMC.  Double check to make sure the following are
362       configured properly in  the  remote  machine's  BMC:  IP  address,  MAC
363       address,  subnet mask, username, user enablement, user privilege, pass‐
364       word,  LAN  privilege,  LAN  enablement,  and  allowed   authentication
365       type(s). For IPMI 2.0 connections, double check to make sure the cipher
366       suite privilege(s) and K_g key are configured  properly.  The  bmc-con‐
367       fig(8) tool can be used to check and/or change these configuration set‐
368       tings.
369
370       The following are common issues for given error messages:
371
372       "username invalid" - The username entered (or a NULL username  if  none
373       was  entered)  is  not  available on the remote machine. It may also be
374       possible the remote BMC's username configuration is incorrect.
375
376       "password invalid" - The password entered (or a NULL password  if  none
377       was  entered)  is not correct. It may also be possible the password for
378       the user is not correctly configured on the remote BMC.
379
380       "password verification timeout" - Password verification has timed  out.
381       A  "password  invalid"  error  (described  above) or a generic "session
382       timeout" (described below) occurred.  During this point in the protocol
383       it cannot be differentiated which occurred.
384
385       "k_g  invalid"  -  The  K_g  key entered (or a NULL K_g key if none was
386       entered) is not correct. It may also be possible the  K_g  key  is  not
387       correctly configured on the remote BMC.
388
389       "privilege level insufficient" - An IPMI command requires a higher user
390       privilege than the one authenticated with. Please try  to  authenticate
391       with a higher privilege. This may require authenticating to a different
392       user which has a higher maximum privilege.
393
394       "privilege level cannot be obtained for  this  user"  -  The  privilege
395       level  you are attempting to authenticate with is higher than the maxi‐
396       mum allowed for this user. Please try again with a lower privilege.  It
397       may  also be possible the maximum privilege level allowed for a user is
398       not configured properly on the remote BMC.
399
400       "authentication type unavailable for attempted privilege level"  -  The
401       authentication  type you wish to authenticate with is not available for
402       this privilege level. Please try again with an alternate authentication
403       type  or  alternate privilege level. It may also be possible the avail‐
404       able authentication types you can authenticate with are  not  correctly
405       configured on the remote BMC.
406
407       "cipher suite id unavailable" - The cipher suite id you wish to authen‐
408       ticate with is not available on the remote BMC. Please try  again  with
409       an  alternate  cipher  suite  id. It may also be possible the available
410       cipher suite ids are not correctly configured on the remote BMC.
411
412       "ipmi 2.0 unavailable" - IPMI 2.0 was  not  discovered  on  the  remote
413       machine. Please try to use IPMI 1.5 instead.
414
415       "connection  timeout"  - Initial IPMI communication failed. A number of
416       potential errors are possible, including an invalid hostname specified,
417       an  IPMI  IP  address  cannot  be  resolved, IPMI is not enabled on the
418       remote server, the network connection is bad, etc. Please  verify  con‐
419       figuration and connectivity.
420
421       "session  timeout"  - The IPMI session has timed out. Please reconnect.
422       If this error occurs often, you may wish to increase the retransmission
423       timeout. Some remote BMCs are considerably slower than others.
424
425       "device  not  found"  - The specified device could not be found. Please
426       check configuration or inputs and try again.
427
428       "driver timeout" - Communication with the driver or  device  has  timed
429       out. Please try again.
430
431       "message  timeout"  - Communication with the driver or device has timed
432       out. Please try again.
433
434       "BMC busy" - The BMC is currently busy. It may be  processing  informa‐
435       tion  or have too many simultaneous sessions to manage. Please wait and
436       try again.
437
438       "could not find inband device" - An inband device could not  be  found.
439       Please  check configuration or specify specific device or driver on the
440       command line.
441
442       Please see WORKAROUNDS below to also if there are any  vendor  specific
443       bugs that have been discovered and worked around.
444

WORKAROUNDS

446       With  so  many different vendors implementing their own IPMI solutions,
447       different vendors may implement their IPMI protocols  incorrectly.  The
448       following  lists  the workarounds currently available to handle discov‐
449       ered compliance issues.
450
451       When possible, workarounds have been implemented so they will be trans‐
452       parent  to  the  user. However, some will require the user to specify a
453       workaround be used via the -W option.
454
455       The hardware listed below may only indicate the hardware that a problem
456       was  discovered  on.  Newer  versions  of hardware may fix the problems
457       indicated below. Similar machines from vendors may or may  not  exhibit
458       the  same  problems.  Different vendors may license their firmware from
459       the same IPMI firmware developer, so it may be worthwhile to try  work‐
460       arounds listed below even if your motherboard is not listed.
461
462       "idzero"  -  This  workaround option will allow empty session IDs to be
463       accepted by the client. It works around IPMI sessions that report empty
464       session  IDs  to  the client. Those hitting this issue may see "session
465       timeout" errors. Issue observed on Tyan S2882 with M3289 BMC.
466
467       "unexpectedauth" - This workaround option will  allow  unexpected  non-
468       null  authcodes  to  be  checked as though they were expected. It works
469       around an issue when packets contain non-null authentication data  when
470       they  should  be null due to disabled per-message authentication. Those
471       hitting this issue may see "session timeout" errors. Issue observed  on
472       Dell PowerEdge 2850,SC1425. Confirmed fixed on newer firmware.
473
474       "forcepermsg" - This workaround option will force per-message authenti‐
475       cation to be used no matter what is advertised by the remote system. It
476       works  around an issue when per-message authentication is advertised as
477       disabled on the remote system, but it is actually required for the pro‐
478       tocol.  Those  hitting  this  issue  may  see "session timeout" errors.
479       Issue observed on IBM eServer 325.
480
481       "endianseq" - This workaround option will flip the endian of  the  ses‐
482       sion  sequence  numbers  to allow the session to continue properly.  It
483       works around IPMI 1.5 session  sequence  numbers  that  are  the  wrong
484       endian.  Those  hitting  this  issue  may see "session timeout" errors.
485       Issue observed on some Sun ILOM 1.0/2.0 (depends on  service  processor
486       endian).
487
488       "authcap"  - This workaround option will skip early checks for username
489       capabilities, authentication capabilities, and K_g  support  and  allow
490       IPMI  authentication  to  succeed.  It  works around multiple issues in
491       which the remote system does not properly report username capabilities,
492       authentication  capabilities,  or  K_g status. Those hitting this issue
493       may  see  "username  invalid",  "authentication  type  unavailable  for
494       attempted privilege level", or "k_g invalid" errors.  Issue observed on
495       Asus  P5M2/P5MT-R/RS162-E4/RX4,  Intel  SR1520ML/X38ML,  and  Sun  Fire
496       2200/4150/4450 with ELOM.
497
498       "intel20"  - This workaround option will work around several Intel IPMI
499       2.0 authentication issues. The issues covered include padding of  user‐
500       names,  automatic  acceptance of a RAKP 4 response integrity check when
501       using the integrity algorithm MD5-128, and password truncation  if  the
502       authentication  algorithm is HMAC-MD5-128. Those hitting this issue may
503       see "username invalid", "password invalid", or  "k_g  invalid"  errors.
504       Issue  observed  on Intel SE7520AF2 with Intel Server Management Module
505       (Professional Edition).
506
507       "supermicro20" - This workaround option will work around several Super‐
508       micro  IPMI 2.0 authentication issues on motherboards w/ Peppercon IPMI
509       firmware. The issues covered include handling invalid length  authenti‐
510       cation  codes.  Those  hitting  this  issue  may see "password invalid"
511       errors.  Issue observed on Supermicro H8QME with SIMSO  daughter  card.
512       Confirmed fixed on newerver firmware.
513
514       "sun20" - This workaround option will work work around several Sun IPMI
515       2.0 authentication issues. The issues covered include invalid  lengthed
516       hash  keys,  improperly  hashed keys, and invalid cipher suite records.
517       Those hitting this issue may see  "password  invalid"  or  "bmc  error"
518       errors.   Issue  observed  on  Sun Fire 4100/4200/4500 with ILOM.  This
519       workaround automatically includes the "opensesspriv" workaround.
520
521       "opensesspriv" - This workaround option will slightly alter  FreeIPMI's
522       IPMI 2.0 connection protocol to workaround an invalid hashing algorithm
523       used by the remote system. The privilege level  sent  during  the  Open
524       Session  stage  of an IPMI 2.0 connection is sometimes invalid and used
525       for hashing keys instead of the privilege level sent during  the  RAKP1
526       connection  stage. Those hitting this issue may see "password invalid",
527       "k_g invalid", "bad rmcpplus status code", or "privilege  level  cannot
528       be  obtained  for  this  user  "  errors.  Issue  observed  on Sun Fire
529       4100/4200/4500 with ILOM,  Inventec  5441/Dell  Xanadu  II,  Supermicro
530       X8DTH,  Supermicro  X8DTG, Supermicro X8DTU, and Intel S5500WBV/Penguin
531       Relion 700. This workaround is automatically triggered with the "sun20"
532       workaround.
533
534       "integritycheckvalue"  -  This  workaround  option  will work around an
535       invalid integrity check value during an IPMI 2.0 session  establishment
536       when  using  Cipher  Suite  ID 0. The integrity check value should be 0
537       length, however the remote motherboard responds with a non-empty field.
538       Those  hitting  this issue may see "k_g invalid" errors. Issue observed
539       on Supermicro  X8DTG,  Supermicro  X8DTU,  and  Intel  S5500WBV/Penguin
540       Relion 700.
541
542       "slowcommit"  -  This  workaround  will slow down commits to the BMC by
543       sleeping a small amount between the commit of sections. It works around
544       motherboards  that have BMCs that can be overwhelmed by commits.  Those
545       hitting this issue may see commit errors or commits not  being  written
546       to the BMC. Issue observed on Supermicro H8QME.

582

KNOWN ISSUES

584       On  older  operating systems, if you input your username, password, and
585       other potentially security relevant information on  the  command  line,
586       this information may be discovered by other users when using tools like
587       the ps(1) command or looking in the /proc file system. It is  generally
588       more  secure  to input password information with options like the -P or
589       -K options. Configuring security relevant information in  the  FreeIPMI
590       configuration file would also be an appropriate way to hide this infor‐
591       mation.
592
593       In order to prevent brute force attacks,  some  BMCs  will  temporarily
594       "lock  up" after a number of remote authentication errors. You may need
595       to wait awhile in order to this temporary "lock up" to pass before  you
596       may authenticate again.
