NAME

6       ipmi-config - IPMI configuration file details
7

DESCRIPTION

9       Before  many  IPMI  tools can be used over a network, a machine's Base‐
10       board Management Controller (BMC) must be configured. The configuration
11       can  be  quite daunting for those who do not know much about IPMI. This
12       manpage hopes to provide enough information  on  BMC  configuration  so
13       that you can configure the BMC for your system. When appropriate, typi‐
14       cal BMC configurations will be suggested.
15
16       The following is an example configuration file partially  generated  by
17       running  the  --checkout  option  with the ipmi-config(8) command. This
18       configuration comes from the core category of configuration values (the
19       default).  This  example  configuration  should  be sufficient for most
20       users after the appropriate local IP and MAC addresses are input.  Fol‐
21       lowing this example, separate sections of this manpage will discuss the
22       different sections of the configuration file in more detail with expla‐
23       nations of how the BMC can be configured for different environments.
24
25       Note  that  many options may or may not be available on your particular
26       machine. For example, Serial-Over-Lan (SOL) is available only  on  IPMI
27       2.0  machines.  Therefore,  if you are looking to configure an IPMI 1.5
28       machine, many of the SOL  or  IPMI  2.0  related  options  will  be  be
29       unavailable  to you. The number of configurable users may also vary for
30       your particular machine.
31
32       The below configuration file and most of this manpage assume  the  user
33       is interested in configuring a BMC for use with IPMI over LAN.  Various
34       configuration options from ipmi-config(8) have been left out or skipped
35       because  it is considered unnecessary.  Future versions of this manpage
36       will try to include more information.

Section User1, User2, ...

230       The User sections of the BMC configuration file are for  username  con‐
231       figuration  for IPMI over LAN communication. The number of users avail‐
232       able to be configured on your system will vary by  manufacturer.   With
233       the exception of the Username for User1, all sections are identical.
234
235       The  username(s)  you  wish  to configure the BMC with are defined with
236       Username. The first username under Section User1 is typically the  NULL
237       username  and  cannot be modified. The password for the username can be
238       specified with Password. It can be left empty to define  a  NULL  pass‐
239       word.  Each  user  you  wish  to  enable  must  be  enabled through the
240       Enable_User configuration option. It is recommended that all  usernames
241       have non-NULL passwords or be disabled for security reasons.
242
243       Lan_Enable_Ipmi_Msgs  is used to enable or disable IPMI over LAN access
244       for the user. This should be set to "Yes" to allow IPMI over LAN  tools
245       to work.
246
247       Lan_Privilege_Limit  specifies  the  maximum  privilege level limit the
248       user is allowed.  Different  IPMI  commands  have  different  privilege
249       restrictions.  For  example,  determining the power status of a machine
250       only requires  the  "User"  privilege  level.  However,  power  cycling
251       requires  the  "Operator" privilege. Typically, you will want to assign
252       atleast one user with a privilege limit of "Administrator" so that  all
253       system functions are available to atleast one user via IPMI over LAN.
254
255       Lan_Session_Limit  specifies  the  number of simultaneous IPMI sessions
256       allowed for the user. Most users will wish to set this to "0" to  allow
257       unlimited simultaneous IPMI sessions. This field is considered optional
258       by IPMI standards, and may result in errors when attempting to  config‐
259       ure  it to a non-zero value. If errors to occur, setting the value back
260       to 0 should resolve problems.
261
262       SOL_Payload_Access specifies if a particular user is allowed to connect
263       with  Serial-Over-LAN  (SOL). This should be set to "Yes" to allow this
264       username to use SOL.
265
266       The example  configuration  above  disables  "User2"  but  enables  the
267       default "NULL" (i.e. anonymous) user. Many IPMI tools (both open-source
268       and vendor) do not allow the user to input a username  and  assume  the
269       NULL  username  by  default.  If  the tools you are interested in using
270       allow usernames to be input, then it is recommended  that  one  of  the
271       non-NULL  usernames be enabled and the NULL username disabled for secu‐
272       rity reasons. It is recommeneded that you disable the NULL username  in
273       section  User1,  so  that  users are required to specify a username for
274       IPMI over LAN communication.
275
276       Some motherboards may require a Username  to  be  configured  prior  to
277       other fields being read/written. If this is the case, those fields will
278       be set to <username-not-set-yet>.
279

Section Lan_Channel

281       The Lan_Channel section configures a variety of IPMI over LAN  configu‐
282       ration parameters. Both Volatile and Non_Volatile configurations can be
283       set. Volatile configurations are immediately configured  onto  the  BMC
284       and  will  have immediate effect on the system. Non_Volatile configura‐
285       tions are only available after the next system reset.  Generally,  both
286       the Volatile and Non_Volatile should be configured identically.
287
288       The  Access_Mode parameter configures the availability of IPMI over LAN
289       on the system. Typically this should be set  to  "Always_Available"  to
290       enable IPMI over LAN.
291
292       The  Privilege_Limit  sets the maximum privilege any user of the system
293       can have when performing IPMI over LAN. This should be set to the maxi‐
294       mum privilege level configured to a username. Typically, this should be
295       set to "Administrator".
296
297       Typically User_Level_Auth and Per_Message_Auth should be set  to  "Yes"
298       for additional security. Disabling User_Level_Auth allows "User" privi‐
299       leged IPMI commands to be executed  without  authentication.  Disabling
300       Per_Message_Auth  allows  fewer  individual  IPMI  messages  to require
301       authentication.
302

Section Lan_Conf

304       Those familiar with setting up networks should find most of the  fields
305       in  this  section self explanatory. The example BMC configuration above
306       illustrates  the  setup   of   a   static   IP   address.   The   field
307       IP_Address_Source  is  configured with "Static". The IP address, subnet
308       mask, and gateway IP addresses of the machine are respecitvely  config‐
309       ured  with the IP_Address, Subnet_Mask, Default_Gateway_Ip_Address, and
310       Backup_Gateway_Ip_Address fields. The respective MAC addresses for  the
311       IP   addresses   are   configured   under   Mac_Address,  Default_Gate‐
312       way_Mac_Address, and Backup_Gateway_Mac_Address.
313
314       It is not required to setup the BMC IP_Address to be the same P_Address
315       used  by  your operating system for that network interface. However, if
316       you choose to use a different address, an alternate  ARP  configuration
317       may need to be setup.
318
319       To  instead  setup  your  BMC  network  information via DHCP, the field
320       IP_Address_Source should be configured with "Use_DHCP".
321
322       It is recommended that static IP addresses be  configured  for  address
323       resolution  reasons. See Lan_Conf_Misc below for a more detailed expla‐
324       nation.

Section Lan_Conf_Auth

327       This section determines what types of  password  authentication  mecha‐
328       nisms  are  allowed  for  users at different privilege levels under the
329       IPMI 1.5 protocol. The currently supported authentication  methods  for
330       IPMI  1.5  are  None (no username/password required), Straight_Password
331       (passwords are sent in the clear), MD2 (passwords are MD2 hashed),  and
332       MD5 (passwords are MD5 hashed).  Different usernames at different priv‐
333       ilege levels may be allowed to authenticate  differently  through  this
334       configuration.  For  example,  a username with "User" privileges may be
335       allowed to authenticate with a straight password, but a  username  with
336       "Administrator" privileges may be allowed only authenticate with MD5.
337
338       The above example configuration supports MD2 and MD5 authentication for
339       all users at the "User", "Operator", and "Administrator" privilege lev‐
340       els.  All  authentication  mechanisms have been disabled for the "Call‐
341       back" privilege level.
342
343       Generally speaking, you do not want to allow any user  to  authenticate
344       with  None  or Straight_Password for security reasons.  MD2 and MD5 are
345       digital signature algorithms that can minimally encrypt  passwords.  If
346       you  have  chosen to support the NULL username (enabled User1) and NULL
347       passwords (NULL password for User1), you will have to enable  the  None
348       authentication fields above to allow users to connect via None.
349

Section Lan_Conf_Security_Keys

351       This  section supports configuration of the IPMI 2.0 (including Serial-
352       over-LAN) K_g key. If your machine does  not  support  IPMI  2.0,  this
353       field will not be configurable.
354
355       The  key is used for two-key authentication in IPMI 2.0. In most tools,
356       when doing IPMI 2.0, the K_g can be optionally  specified.  It  is  not
357       required for IPMI 2.0 operation.
358
359       In  the above example, we have elected to leave this field blank so the
360       K_g key is not used.
361

Section Lan_Conf_Misc

363       This section lists miscellaneous IPMI over LAN  configuration  options.
364       These  are optional IPMI configuration options that are not implemented
365       on all BMCs.
366
367       Normally, a client cannot resolve the ethernet MAC address without  the
368       remote  operating system running. However, IPMI over LAN would not work
369       when a machine is powered off or if the IP address used by the  operat‐
370       ing  system for that network interface differs from the BMC IP Address.
371       One way to work around this is  through  gratuitous  ARPs.   Gratuitous
372       ARPs are ARP packets generated by the BMC and sent out to advertise the
373       BMC's IP and MAC address.  Other machines on the network can store this
374       information  in their local ARP cache for later IP/hostname resolution.
375       This would allow IPMI over LAN to work when the remote machine is  pow‐
376       ered  off.  The  Enable_Gratuitous_Arps  option allows you to enable or
377       disable this feature. The Gratuitous_Arp_Interval option allows you  to
378       configure the frequency at which gratuitous ARPs are sent onto the net‐
379       work.
380
381       Instead of gratuitous ARPs  some  BMCs  are  able  to  respond  to  ARP
382       requests,  even  when  powered  off.  If  offerred, this feature can be
383       enabled through the Enable_Arp_Response option.
384
385       Generally speaking, turning on gratuitous ARPs is acceptable.  However,
386       it  will  increase traffic on your network.  If you are using IPMI on a
387       large cluster, the gratuitous ARPs may easily flood your network.  They
388       should  be tuned to occur less frequently or disabled. If disabled, the
389       remote machine's MAC address should be permanently stored in the  local
390       ARP cache through arp(8).
391
392       See  bmc-watchdog(8)  for  a  method which allows gratuitous ARPs to be
393       disabled when the operating system is running,  but  enabled  when  the
394       system is down.
395

Section Rmcpplus_Conf_Privilege

397       This  section supports configuration of the IPMI 2.0 (including Serial-
398       over-LAN) cipher suite IDs. If your machine does not support IPMI  2.0,
399       the fields will not be configurable.
400
401       Each cipher suite ID describes a combination of an authentication algo‐
402       rithm, integrity algorithm, and encryption algorithm for IPMI 2.0.  The
403       authentication  algorithm is used for user authentication with the BMC.
404       The integrity algorithm is used for generating signatures on IPMI pack‐
405       ets.  The  confidentiality  algorithm  is used for encrypting data. The
406       configuration in this section enables certain cipher suite  IDs  to  be
407       enabled  or  disabled,  and  the maximum privilege level a username can
408       authenticate with.
409
410       The following table shows the cipher suite ID to algorithms mapping:
411
412       0 - Authentication Algorithm = None; Integrity Algorithm = None; Confi‐
413       dentiality Algorithm = None
414
415       1  -  Authentication Algorithm = HMAC-SHA1; Integrity Algorithm = None;
416       Confidentiality Algorithm = None
417
418       2 - Authentication Algorithm = HMAC-SHA1; Integrity Algorithm  =  HMAC-
419       SHA1-96; Confidentiality Algorithm = None
420
421       3  -  Authentication Algorithm = HMAC-SHA1; Integrity Algorithm = HMAC-
422       SHA1-96; Confidentiality Algorithm = AES-CBC-128
423
424       4 - Authentication Algorithm = HMAC-SHA1; Integrity Algorithm  =  HMAC-
425       SHA1-96; Confidentiality Algorithm = xRC4-128
426
427       5  -  Authentication Algorithm = HMAC-SHA1; Integrity Algorithm = HMAC-
428       SHA1-96; Confidentiality Algorithm = xRC4-40
429
430       6 - Authentication Algorithm = HMAC-MD5; Integrity  Algorithm  =  None;
431       Confidentiality Algorithm = None
432
433       7  -  Authentication  Algorithm = HMAC-MD5; Integrity Algorithm = HMAC-
434       MD5-128; Confidentiality Algorithm = None
435
436       8 - Authentication Algorithm = HMAC-MD5; Integrity  Algorithm  =  HMAC-
437       MD5-128; Confidentiality Algorithm = AES-CBC-128
438
439       9  -  Authentication  Algorithm = HMAC-MD5; Integrity Algorithm = HMAC-
440       MD5-128; Confidentiality Algorithm = xRC4-128
441
442       10 - Authentication Algorithm = HMAC-MD5; Integrity Algorithm  =  HMAC-
443       MD5-128; Confidentiality Algorithm = xRC4-40
444
445       11  -  Authentication  Algorithm  =  HMAC-MD5;  Integrity  Algorithm  =
446       MD5-128; Confidentiality Algorithm = None
447
448       12  -  Authentication  Algorithm  =  HMAC-MD5;  Integrity  Algorithm  =
449       MD5-128; Confidentiality Algorithm = AES-CBC-128
450
451       13  -  Authentication  Algorithm  =  HMAC-MD5;  Integrity  Algorithm  =
452       MD5-128; Confidentiality Algorithm = xRC4-128
453
454       14  -  Authentication  Algorithm  =  HMAC-MD5;  Integrity  Algorithm  =
455       MD5-128; Confidentiality Algorithm = xRC4-40
456
457       Generally  speaking, HMAC-SHA1 based algorithms are stronger than HMAC-
458       MD5, which are better than MD5-128  algorithms.  AES-CBC-128  confiden‐
459       tiality  algorithms  are  stronger  than xRC4-128 algorithms, which are
460       better than xRC4-40 algorithms. Cipher suite ID 3  is  therefore  typi‐
461       cally  considered  the  most  secure. Some users may wish to set cipher
462       suite ID 3 to a privilege level and disable all remaining cipher  suite
463       IDs.
464
465       The  above  example  configuration  has  decided to allow any user with
466       "Administrator" privileges use any Cipher Suite algorithm  suite  which
467       requires  an  authentication, integrity, and confidentiality algorithm.
468       Typically, the maximum privilege level configured to a username  should
469       be  set for atleast one cipher suite ID. Typically, this is the "Admin‐
470       istrator" privilege.
471
472       A number of cipher suite IDs are optionally implemented, so the  avail‐
473       able cipher suite IDs available your system may vary.
474

Section SOL_Conf

476       This  section  is for setting up Serial-Over-Lan (SOL) and will only be
477       available for configuration on those machines. SOL can be enabled  with
478       the Enable_SOL field. The minimum privilege level required for connect‐
479       ing with SOL is specified by SOL_Privilege_Level.  This should  be  set
480       to  the  maximum  privilege level configured to a username that has SOL
481       enabled. Typically, this is the "Administrator" privilege.  Authentica‐
482       tion   and   Encryption   can   be  forced  or  not  using  the  fields
483       Force_SOL_Payload_Authentication    and    Force_SOL_Payload_Encryption
484       respectively.  It  is recommended that these be set on. However, forced
485       authentication and/or encryption support depend on the cipher suite IDs
486       supported.
487
488       The     Character_Accumulate_Interval,    Character_Send_Threshold    ,
489       SOL_Retry_Count and , SOL_Retry_Interval options are used  to  set  SOL
490       character  output  speeds. Character_Accumulate_Interval determines how
491       often serial data should be regularly sent and Character_Send_Threshold
492       indicates the character count that if passed, will force serial data to
493       be sent. SOL_Retry_Count indicates  how  many  times  packets  must  be
494       retransmitted  if acknowledgements are not received. SOL_Retry_Interval
495       indicates the timeout interval. Generally, the manufacturer recommended
496       numbers  will  be  sufficient. However, you may wish to experiment with
497       these values for faster SOL throughput.
498
499       The Non_Volatile_Bit_Rate and Volatile_Bit_Rate determine the  baudrate
500       the  BMC should use. This should match the baudrate set in the BIOS and
501       operating system, such as  agetty(8).   Generally  speaking,  both  the
502       Volatile and Non_Volatile options should be set identically.
503
504       In addition to enabling SOL in this section, individual users most also
505       be capable of connecting with  SOL.  See  the  section  Section  User1,
506       User2, ...  above for details.
