NAME

       bmc-config - configure BMC values

SYNOPSIS

       bmc-config [OPTION...]

DESCRIPTION

       Bmc-config  is  used  to  get  and  set  BMC  configuration parameters, such as usernames,
       passwords, networking information, security, Serial-over-LAN (SOL), and  other  core  IPMI
       fields.  This  configuration  is  required  before most IPMI tools can be used to access a
       machine remotely.  The majority of configuration operations require ADMIN  privilege  when
       using  bmc-config out-of-band. Although connecting via a user with ADMIN privileges is not
       required for out-of-band use, the vast majority  of  configuration  options  will  not  be
       retrieved  or  set.   For  configuration  of  chassis,  platform event filtering (PEF), or
       sensors, please  see  the  ipmi-chassis-config(8),  ipmi-pef-config(8),  or  ipmi-sensors-
       config(8)  tools  respectively.  For  some  OEM  specific configurations, please see ipmi-
       oem(8).

       Listed  below  are  general  IPMI  options,  tool  specific  options,   trouble   shooting
       information,   workaround   information,   examples,  and  known  issues.  For  a  general
       introduction to FreeIPMI please see freeipmi(7).  See GENERAL USE below for a  description
       on how most will want to use Bmc-config.

GENERAL OPTIONS

       The following options are general options for configuring IPMI communication and executing
       general tool commands.

       -D IPMIDRIVER, --driver-type=IPMIDRIVER
              Specify the driver type to use instead of doing an auto selection.   The  currently
              available  outofband  drivers  are LAN and LAN_2_0, which perform IPMI 1.5 and IPMI
              2.0 respectively. The currently available inband drivers are KCS,  SSIF,  OPENIPMI,
              and SUNBMC.

       --disable-auto-probe
              Do not probe in-band IPMI devices for default settings.

       --driver-address=DRIVER-ADDRESS
              Specify  the in-band driver address to be used instead of the probed value. DRIVER-
              ADDRESS should be prefixed with "0x" for a hex value and '0' for an octal value.

       --driver-device=DEVICE
              Specify the in-band driver device path to be used instead of the probed path.

       --register-spacing=REGISTER-SPACING
              Specify the in-band driver register spacing instead of the probed  value.  Argument
              is in bytes (i.e. 32bit register spacing = 4)

       -h IPMIHOST1,IPMIHOST2,..., --hostname=IPMIHOST1,IPMIHOST2,...
              Specify the remote host(s) to communicate with. Multiple hostnames may be separated
              by comma or may be specified in a range format; see HOSTRANGED SUPPORT below.

       -u USERNAME, --username=USERNAME
              Specify the username to use when authenticating  with  the  remote  host.   If  not
              specified,  a null (i.e. anonymous) username is assumed. The user must have atleast
              ADMIN privileges in order for this tool to operate fully.

       -p PASSWORD, --password=PASSWORD
              Specify the password to use when authenticationg with  the  remote  host.   If  not
              specified,  a  null password is assumed. Maximum password length is 16 for IPMI 1.5
              and 20 for IPMI 2.0.

       -P, --password-prompt
              Prompt for password to avoid possibility of listing it in process lists.

       -k K_G, --k-g=K_G
              Specify the K_g BMC key to use when authenticating with the remote  host  for  IPMI
              2.0. If not specified, a null key is assumed. To input the key in hexadecimal form,
              prefix the string with '0x'. E.g., the key 'abc' can be entered with the either the
              string 'abc' or the string '0x616263'

       -K, --k-g-prompt
              Prompt for k-g to avoid possibility of listing it in process lists.

       --session-timeout=MILLISECONDS
              Specify  the  session  timeout  in milliseconds. Defaults to 20000 milliseconds (20
              seconds) if not specified.

       --retransmission-timeout=MILLISECONDS
              Specify the  packet  retransmission  timeout  in  milliseconds.  Defaults  to  1000
              milliseconds  (1  second)  if  not  specified. The retransmission timeout cannot be
              larger than the session timeout.

       -a AUTHENTICATION-TYPE, --authentication-type=AUTHENTICATION-TYPE
              Specify  the  IPMI  1.5  authentication  type  to  use.  The  currently   available
              authentication types are NONE, STRAIGHT_PASSWORD_KEY, MD2, and MD5. Defaults to MD5
              if not specified.

       -I CIPHER-SUITE-ID, --cipher-suite-id=CIPHER-SUITE-ID
              Specify the IPMI 2.0 cipher suite ID to use. The Cipher Suite ID identifies  a  set
              of  authentication,  integrity,  and confidentiality algorithms to use for IPMI 2.0
              communication. The authentication algorithm identifies the  algorithm  to  use  for
              session  setup, the integrity algorithm identifies the algorithm to use for session
              packet signatures, and the confidentiality algorithm identifies  the  algorithm  to
              use  for  payload  encryption.  Defaults to cipher suite ID 3 if not specified. The
              following cipher suite ids are currently supported:

              0 - Authentication Algorithm = None; Integrity Algorithm  =  None;  Confidentiality
              Algorithm = None

              1   -   Authentication   Algorithm   =   HMAC-SHA1;  Integrity  Algorithm  =  None;
              Confidentiality Algorithm = None

              2 - Authentication Algorithm  =  HMAC-SHA1;  Integrity  Algorithm  =  HMAC-SHA1-96;
              Confidentiality Algorithm = None

              3  -  Authentication  Algorithm  =  HMAC-SHA1;  Integrity Algorithm = HMAC-SHA1-96;
              Confidentiality Algorithm = AES-CBC-128

              6  -  Authentication  Algorithm   =   HMAC-MD5;   Integrity   Algorithm   =   None;
              Confidentiality Algorithm = None

              7  -  Authentication  Algorithm  =  HMAC-MD5;  Integrity  Algorithm = HMAC-MD5-128;
              Confidentiality Algorithm = None

              8 - Authentication  Algorithm  =  HMAC-MD5;  Integrity  Algorithm  =  HMAC-MD5-128;
              Confidentiality Algorithm = AES-CBC-128

              11   -   Authentication  Algorithm  =  HMAC-MD5;  Integrity  Algorithm  =  MD5-128;
              Confidentiality Algorithm = None

              12  -  Authentication  Algorithm  =  HMAC-MD5;  Integrity  Algorithm   =   MD5-128;
              Confidentiality Algorithm = AES-CBC-128

              17 - Authentication Algorithm = HMAC-SHA256; Integrity Algorithm = HMAC_SHA256_128;
              Confidentiality Algorithm = AES-CBC-128

       -l PRIVILEGE-LEVEL, --privilege-level=PRIVILEGE-LEVEL
              Specify the privilege level to be used. The currently  available  privilege  levels
              are USER, OPERATOR, and ADMIN. Defaults to ADMIN if not specified.

       --config-file=FILE
              Specify an alternate configuration file.

       -W WORKAROUNDS, --workaround-flags=WORKAROUNDS
              Specify  workarounds  to  vendor  compliance  issues.  Multiple  workarounds can be
              specified separated by commas. A special command line flag of "none", will indicate
              no  workarounds (may be useful for overriding configured defaults). See WORKAROUNDS
              below for a list of available workarounds.

       --debug
              Turn on debugging.

       -?, --help
              Output a help list and exit.

       --usage
              Output a usage message and exit.

       -V, --version
              Output the program version and exit.

CONFIG OPTIONS

       The following options are used to read,  write,  and  find  differences  in  configuration
       values.

       -o, --checkout
              Fetch configuration information.

       -c, --commit
              Update configuration information from a config file or key pairs.

       -d, --diff
              Show differences between stored information and a config file or key pairs.

       -n FILENAME, --filename=FILENAME
              Specify a config file for checkout/commit/diff.

       -e "KEY=VALUE", --key-pair="KEY=VALUE"
              Specify    KEY=VALUE    pairs    for    checkout/commit/diff.    Specify   KEY   by
              SectionName:FieldName. This option can be  used  multiple  times.  On  commit,  any
              KEY=VALUE pairs will overwrite any pairs specified in a file with --filename.

       -S SECTION, --section=SECTION
              Specify a SECTION for checkout. This option can be used multiple times.

       -L, --listsections
              List  available sections for checkout. Some sections in the list may not be checked
              out by default and may require verbosity to be increased.

       -v, --verbose
              Output verbose information. When used with --checkout, additional uncommon sections
              and/or  fields  will  be  shown.  In  bmc-config, this includes checking out Serial
              Configuration parameters, Vlan parameters, IPv4 Header parameters, RMCP  port,  and
              sections for each channel on a system, if multiple channels exist.

       -vv    Output  very verbose information. Output additional detailed information about what
              fields can and cannot be checked out,  and  sometimes  the  reason  why.  Sometimes
              output fields that are identified as unsupported on the motherboard.

       --lan-channel-number=NUMBER
              Use  an  specific  channel  number  for  LAN  configuration. Particularly useful if
              motherboard contains multiple LAN channels and a user wishes to use a specific one.

       --serial-channel-number=NUMBER
              Use an specific channel number for serial  configuration.  Particularly  useful  if
              motherboard  contains  multiple serial channels and a user wishes to use a specific
              one.

       --sol-channel-number=NUMBER
              Use an specific channel  number  for  SOL  configuration.  Particularly  useful  if
              motherboard contains multiple SOL channels and a user wishes to use a specific one.

HOSTRANGED OPTIONS

       The  following  options  manipulate  hostranged  output.  See HOSTRANGED SUPPORT below for
       additional information on hostranges.

       -B, --buffer-output
              Buffer hostranged output. For each node, buffer standard output until the node  has
              completed  its  IPMI  operation.  When  specifying  this option, data may appear to
              output slower to the user since the the entire IPMI operation must complete  before
              any data can be output.  See HOSTRANGED SUPPORT below for additional information.

       -C, --consolidate-output
              Consolidate  hostranged  output.  The  complete  standard  output  from  every node
              specified will be consolidated so that nodes with identical output are  not  output
              twice.  A  header  will  list  those  nodes with the consolidated output. When this
              option is specified, no output can be seen until the IPMI operations to  all  nodes
              has  completed.  If  the  user  breaks  out  of  the  program  early, all currently
              consolidated output will be dumped. See HOSTRANGED  SUPPORT  below  for  additional
              information.

       -F NUM, --fanout=NUM
              Specify  multiple host fanout. A "sliding window" (or fanout) algorithm is used for
              parallel IPMI communication so that slower nodes or timed out nodes will not impede
              parallel communication. The maximum number of threads available at the same time is
              limited by the fanout. The default is 64.

       -E, --eliminate
              Eliminate hosts determined as undetected by ipmidetect.  This  attempts  to  remove
              the  common  issue  of  hostranged  execution timing out due to several nodes being
              removed from service in a large cluster. The ipmidetectd daemon must be running  on
              the node executing the command.

       --always-prefix
              Always  prefix output, even if only one host is specified or communicating in-band.
              This option is primarily useful for scripting purposes. Option will be  ignored  if
              specified with the -C option.

GENERAL USE

       Most users of will want to:

       A)  Run with --checkout to get a copy of the current configuration and store it in a file.
       The standard output can be redirected to a file or  a  file  can  be  specified  with  the
       --filename option.

       B) Edit the configuration file with an editor.

       C)   Commit   the  configuration  back  using  the  --commit  option  and  specifying  the
       configuration file with the --filename option.  The  configuration  can  be  committed  to
       multiple hosts in parallel via the hostrange support.

       Although not typically necessarily, some motherboards do not store configuration values in
       non-volatile memory. Therefore, after system reboots, some configuration values  may  have
       changed. The user may wish to run configuration tools on each boot to ensure configuration
       values remain.

       Comments throughout the checked out file will give instructions on how  to  configure  the
       fields.   The  bmc-config.conf(5)  manpage  also  provides  additional  information on the
       meaning of different fields.

       For users with large clusters or sets of nodes, you may wish to use the same configuration
       file  for all nodes. The one problem with this is that the IP address and MAC address will
       be different on each node in your cluster and thus can't be configured  through  the  same
       config  file. The IP address and MAC address in your config file may be overwritten on the
       command line using --key-pair option. The following example could be used in a  script  to
       configure  each  node in a cluster with the same BMC config file. The script only needs to
       determine the correct IP address and MAC address to use.

       # bmc-config --commit -k  Lan_Conf:Ip_Address=$MY_IP  -k  Lan_Conf:Mac_Address=$MY_MAC  -n
       my_bmc.conf

BMC-CONFIG SPECIAL CASE CONFIGURATION INFORMATION

       The  UserN:Password  fields  (where  N is a number) cannot be checked out on some systems,
       therefore the checked out value will always be blank.

       The UserN:Enable_User field (where N is a number) cannot be  checked  out  on  older  IPMI
       systems, therefore the checked out value will sometime be blank.

       The  UserN:Lan_Session_Limit  and  UserN:Serial_Session_Limit fields (where N is a number)
       cannot be checked out on some systems, therefore the checked  out  value  will  always  be
       blank.  If  not  specified in later commits of configurations, the field may be reset to 0
       due to a requirement that other fields (configured along  with  the  session  limit)  will
       require  an input value for the session limit.  Under most conditions, it is not necessary
       to set this field and most users may  choose  to  ignore  it.  This  field  is  considered
       optional  by IPMI standards, and may result in errors when attempting to configure it to a
       non-zero value. If errors to occur, setting the value back to 0 should resolve problems.

       The fields Lan_Conf:IP_Address and Lan_Conf:MAC_Address cannot be  committed  in  parallel
       via  hostrange  support.  Each machine must be configured with a unique IP Address and MAC
       Address tuple, therefore we disallow this configuration in bmc-config.

       On some motherboards, Lan_Conf:MAC_Address may  be  read  only  and  the  MAC  address  is
       automatically configured.

       On  some  motherboards,  Lan_Conf:MAC_Address  may  be  read  only  and the MAC address is
       configured via an OEM command. See ipmi-oem(8)  to  see  if  OEM  configuration  for  your
       motherboard is supported.

       On  some  motherboards, a number of user configuration fields cannot be read or configured
       until after a non-null username or non-null password  is  configured.  In  some  of  these
       cases, an appropriate output in the config file will indicate this situation. However, not
       all motherboard corner cases may be detected. Users may  wish  to  play  around  with  the
       ordering of fields to work around these problems.

       On  some motherboards, OEM Authentication in Lan_Conf_Auth cannot be enabled. However, the
       default motherboard settings have these fields enabled. Users are advised to  disable  all
       OEM Authentication in this section.

       On  some  motherboards,  multiple  channels  may  exist  for  either  LAN  or  Serial IPMI
       communication. If multiple channels exist, configuration of both channels  can  be  viewed
       and  ultimately  configured  by running --checkout under verbose mode. Each section or key
       name will be suffixed appropriately with the word Channel  and  the  channel  number.  For
       example,  you  might  see  a  Lan_Conf_Channel_1  and  Lan_Conf_Channel_3,  where  you can
       configure LAN configuration on Channels 1 and 3 respectively.

       On some motherboards, configuration changes will not be "absorbed" by the system until the
       motherboard  is hard-reset. This can be accomplished by physically powering off and on the
       system (e.g. button push), or it can be accomplished through a  cold-reset.  A  cold-reset
       can be executed via bmc-device.

HOSTRANGED SUPPORT

       Multiple  hosts  can  be  input  either as an explicit comma separated lists of hosts or a
       range of hostnames in the general form: prefix[n-m,l-k,...], where n < m and l <  k,  etc.
       The  later  form  should  not  be confused with regular expression character classes (also
       denoted by []). For  example,  foo[19]  does  not  represent  foo1  or  foo9,  but  rather
       represents a degenerate range: foo19.

       This  range  syntax  is  meant  only  as  a convenience on clusters with a prefixNN naming
       convention and specification of ranges should not be  considered  necessary  --  the  list
       foo1,foo9 could be specified as such, or by the range foo[1,9].

       Some examples of range usage follow:
           foo[01-05] instead of foo01,foo02,foo03,foo04,foo05
           foo[7,9-10] instead of foo7,foo9,foo10
           foo[0-3] instead of foo0,foo1,foo2,foo3

       As  a  reminder  to  the reader, some shells will interpret brackets ([ and ]) for pattern
       matching. Depending on your shell, it may be necessary  to  enclose  ranged  lists  within
       quotes.

       When  multiple hosts are specified by the user, a thread will be executed for each host in
       parallel up to the configured fanout (which can be adjusted via the -F option). This  will
       allow communication to large numbers of nodes far more quickly than if done in serial.

       By  default,  standard  output  from  each node specified will be output with the hostname
       prepended to each line. Although this output is readable in many  situations,  it  may  be
       difficult  to  read  in  other  situations. For example, output from multiple nodes may be
       mixed together. The -B and -C options can be used to change this default.

       In-band IPMI Communication will be used when  the  host  "localhost"  is  specified.  This
       allows the user to add the localhost into the hostranged output.

GENERAL TROUBLESHOOTING

       Most often, IPMI problems are due to configuration problems.

       IPMI  over  LAN  problems  involve a misconfiguration of the remote machine's BMC.  Double
       check to make sure the following are configured properly in the remote machine's  BMC:  IP
       address,  MAC  address,  subnet mask, username, user enablement, user privilege, password,
       LAN  privilege,  LAN  enablement,  and  allowed  authentication  type(s).  For  IPMI   2.0
       connections,  double  check  to  make  sure  the cipher suite privilege(s) and K_g key are
       configured properly. The bmc-config(8) tool can be  used  to  check  and/or  change  these
       configuration settings.

       Inband IPMI problems are typically caused by improperly configured drivers or non-standard
       BMCs.

       In addition to the troubleshooting tips below, please see WORKAROUNDS  below  to  also  if
       there are any vendor specific bugs that have been discovered and worked around.

       Listed  below  are  many of the common issues for error messages.  For additional support,
       please e-mail the <freeipmi-users@gnu.org> mailing list.

       "username invalid" - The username entered (or a NULL username if none was entered) is  not
       available  on  the  remote  machine.  It  may  also  be possible the remote BMC's username
       configuration is incorrect.

       "password invalid" - The password entered (or a NULL password if none was entered) is  not
       correct.  It may also be possible the password for the user is not correctly configured on
       the remote BMC.

       "password verification timeout" -  Password  verification  has  timed  out.   A  "password
       invalid"  error  (described  above)  or  a  generic  "session  timeout"  (described below)
       occurred.  During this point in the protocol it cannot be differentiated which occurred.

       "k_g invalid" - The K_g key entered (or a NULL  K_g  key  if  none  was  entered)  is  not
       correct.  It  may  also  be possible the K_g key is not correctly configured on the remote
       BMC.

       "privilege level insufficient" - An IPMI command requires a higher user privilege than the
       one  authenticated  with.  Please  try  to  authenticate with a higher privilege. This may
       require authenticating to a different user which has a higher maximum privilege.

       "privilege level cannot be  obtained  for  this  user"  -  The  privilege  level  you  are
       attempting  to  authenticate with is higher than the maximum allowed for this user. Please
       try again with a lower privilege. It may also be  possible  the  maximum  privilege  level
       allowed for a user is not configured properly on the remote BMC.

       "authentication  type unavailable for attempted privilege level" - The authentication type
       you wish to authenticate with is not available for this privilege level. Please try  again
       with  an  alternate  authentication  type  or  alternate  privilege  level. It may also be
       possible the available authentication types you can authenticate with  are  not  correctly
       configured on the remote BMC.

       "cipher  suite  id unavailable" - The cipher suite id you wish to authenticate with is not
       available on the remote BMC. Please try again with an alternate cipher suite  id.  It  may
       also be possible the available cipher suite ids are not correctly configured on the remote
       BMC.

       "ipmi 2.0 unavailable" - IPMI 2.0 was not discovered on the remote machine. Please try  to
       use IPMI 1.5 instead.

       "connection timeout" - Initial IPMI communication failed. A number of potential errors are
       possible, including an invalid hostname specified, an IPMI IP address cannot be  resolved,
       IPMI  is  not  enabled  on  the  remote server, the network connection is bad, etc. Please
       verify configuration and connectivity.

       "session timeout" - The IPMI session has timed  out.  Please  reconnect.   If  this  error
       occurs  often,  you  may wish to increase the retransmission timeout. Some remote BMCs are
       considerably slower than others.

       "device not found" - The specified device could not be found. Please  check  configuration
       or inputs and try again.

       "driver  timeout"  -  Communication  with  the  driver or device has timed out. Please try
       again.

       "message timeout" - Communication with the driver or device  has  timed  out.  Please  try
       again.

       "BMC  busy" - The BMC is currently busy. It may be processing information or have too many
       simultaneous sessions to manage. Please wait and try again.

       "could not find inband device" - An inband  device  could  not  be  found.   Please  check
       configuration or specify specific device or driver on the command line.

       "driver  timeout"  -  The  inband  driver  has timed out communicating to the local BMC or
       service processor. The BMC or service processor may be busy or (worst case) possibly  non-
       functioning.

WORKAROUNDS

       With  so  many  different vendors implementing their own IPMI solutions, different vendors
       may implement their IPMI protocols  incorrectly.  The  following  describes  a  number  of
       workarounds  currently  available  to  handle discovered compliance issues. When possible,
       workarounds have been implemented so they will be transparent to the user.  However,  some
       will require the user to specify a workaround be used via the -W option.

       The hardware listed below may only indicate the hardware that a problem was discovered on.
       Newer versions of hardware may fix the problems indicated  below.  Similar  machines  from
       vendors  may  or  may  not  exhibit the same problems. Different vendors may license their
       firmware from the same IPMI firmware developer, so it may be worthwhile to try workarounds
       listed below even if your motherboard is not listed.

       If you believe your hardware has an additional compliance issue that needs a workaround to
       be implemented, please contact the FreeIPMI  maintainers  on  <freeipmi-users@gnu.org>  or
       <freeipmi-devel@gnu.org>.

       assumeio  - This workaround flag will assume inband interfaces communicate with system I/O
       rather than being memory-mapped. This will work around systems that  report  invalid  base
       addresses.  Those  hitting  this  issue  may see "device not supported" or "could not find
       inband device" errors.  Issue observed on HP ProLiant DL145 G1.

       spinpoll - This workaround flag will inform some inband  drivers  (most  notably  the  KCS
       driver)  to  spin  while  polling  rather  than  putting  the  process  to sleep. This may
       significantly improve the wall clock running time of tools  because  an  operating  system
       scheduler's granularity may be much larger than the time it takes to perform a single IPMI
       message transaction. However, by spinning, your system may be performing less useful  work
       by not contexting out the tool for a more useful task.

       authcap  -  This  workaround  flag  will  skip  early  checks  for  username capabilities,
       authentication capabilities, and K_g support and allow IPMI authentication to succeed.  It
       works  around multiple issues in which the remote system does not properly report username
       capabilities, authentication capabilities, or K_g status. Those hitting this issue may see
       "username  invalid",  "authentication  type unavailable for attempted privilege level", or
       "k_g  invalid"  errors.   Issue   observed   on   Asus   P5M2/P5MT-R/RS162-E4/RX4,   Intel
       SR1520ML/X38ML, and Sun Fire 2200/4150/4450 with ELOM.

       idzero  -  This workaround flag will allow empty session IDs to be accepted by the client.
       It works around IPMI sessions that report empty session IDs to the client.  Those  hitting
       this issue may see "session timeout" errors. Issue observed on Tyan S2882 with M3289 BMC.

       unexpectedauth  -  This  workaround  flag  will  allow unexpected non-null authcodes to be
       checked as though they were expected. It works around an issue when packets  contain  non-
       null   authentication   data  when  they  should  be  null  due  to  disabled  per-message
       authentication. Those hitting this issue may see "session timeout" errors. Issue  observed
       on Dell PowerEdge 2850,SC1425. Confirmed fixed on newer firmware.

       forcepermsg  -  This  workaround  flag will force per-message authentication to be used no
       matter what is advertised by the remote system. It works around an issue when  per-message
       authentication is advertised as disabled on the remote system, but it is actually required
       for the protocol. Those hitting this  issue  may  see  "session  timeout"  errors.   Issue
       observed on IBM eServer 325.

       endianseq  -  This workaround flag will flip the endian of the session sequence numbers to
       allow the session to continue properly. It works around IPMI 1.5 session sequence  numbers
       that  are  the  wrong  endian.  Those hitting this issue may see "session timeout" errors.
       Issue observed on some Sun ILOM 1.0/2.0 (depends on service processor endian).

       intel20 - This workaround flag will work around  several  Intel  IPMI  2.0  authentication
       issues.  The  issues  covered include padding of usernames, and password truncation if the
       authentication algorithm is HMAC-MD5-128. Those  hitting  this  issue  may  see  "username
       invalid",  "password  invalid", or "k_g invalid" errors. Issue observed on Intel SE7520AF2
       with Intel Server Management Module (Professional Edition).

       supermicro20 -  This  workaround  flag  will  work  around  several  Supermicro  IPMI  2.0
       authentication  issues  on  motherboards  w/  Peppercon  IPMI firmware. The issues covered
       include handling invalid length authentication codes. Those hitting  this  issue  may  see
       "password  invalid"  errors.  Issue observed on Supermicro H8QME with SIMSO daughter card.
       Confirmed fixed on newerver firmware.

       sun20 - This workaround flag will work work around several  Sun  IPMI  2.0  authentication
       issues. The issues covered include invalid lengthed hash keys, improperly hashed keys, and
       invalid cipher suite records. Those hitting this issue may see "password invalid" or  "bmc
       error"  errors.   Issue  observed  on  Sun Fire 4100/4200/4500 with ILOM.  This workaround
       automatically includes the "opensesspriv" workaround.

       opensesspriv - This workaround flag will slightly alter  FreeIPMI's  IPMI  2.0  connection
       protocol  to  workaround  an  invalid  hashing  algorithm  used  by the remote system. The
       privilege level sent during the Open Session stage of an IPMI 2.0 connection is  used  for
       hashing  keys instead of the privilege level sent during the RAKP1 connection stage. Those
       hitting this issue may see "password invalid", "k_g  invalid",  or  "bad  rmcpplus  status
       code"  errors.   Issue  observed  on Sun Fire 4100/4200/4500 with ILOM, Inventec 5441/Dell
       Xanadu II, Supermicro X8DTH, Supermicro X8DTG, Intel S5500WBV/Penguin  Relion  700,  Intel
       S2600JF/Appro 512X, and Quanta QSSC-S4R//Appro GB812X-CN. This workaround is automatically
       triggered with the "sun20" workaround.

       integritycheckvalue - This workaround flag will work around  an  invalid  integrity  check
       value during an IPMI 2.0 session establishment when using Cipher Suite ID 0. The integrity
       check value should be 0 length, however the remote motherboard responds with  a  non-empty
       field. Those hitting this issue may see "k_g invalid" errors. Issue observed on Supermicro
       X8DTG, Supermicro X8DTU, and Intel S5500WBV/Penguin Relion 700,  and  Intel  S2600JF/Appro
       512X.

       No  IPMI  1.5  Support  -  Some  motherboards that support IPMI 2.0 have been found to not
       support IPMI 1.5. Those hitting this issue may see "ipmi 2.0 unavailable"  or  "connection
       timeout"  errors. This issue can be worked around by using IPMI 2.0 instead of IPMI 1.5 by
       specifying --driver-address=LAN_2_0. Issue observed on HP Proliant DL 145.

       slowcommit - This workaround will slow down commits to the  BMC  by  sleeping  one  second
       between  the  commit  of sections. It works around motherboards that have BMCs that can be
       overwhelmed by commits.  Those hitting this issue may see commit  errors  or  commits  not
       being written to the BMC. Issue observed on Supermicro H8QME.

       veryslowcommit  - This workaround will slow down commits to the BMC by sleeping one second
       between the commit of every key. It works around motherboards that have BMCs that  can  be
       overwhelmed  by  commits.   Those  hitting this issue may see commit errors or commits not
       being written to the BMC. Issue observed on Quanta S99Q/Dell FS12-TY.

       "solchannelassumelanchannel" - This workaround will force bmc-config to  assume  that  the
       channel  used  SOL is identical to the channel used for LAN. On some motherboards, the SOL
       channel is reported incorrectly, leading to incorrect configuration.  Most  notably,  this
       problem  has  come  up  when attempting to configure multiple channels.  Issue observed on
       Intel S5500WBV/Penguin Relion 700.

       pair="lan_conf_misc:gratuitous_arp_interval=4"

       Commit    all     configuration     values     from     bmc-data-updt.conf     and     key
       'lan_conf_misc:gratuitous_arp_interval' of value '4'.

KNOWN ISSUES

       On  older  operating  systems, if you input your username, password, and other potentially
       security relevant information on the command line, this information may be  discovered  by
       other  users  when using tools like the ps(1) command or looking in the /proc file system.
       It is generally more secure to input password information with options like the -P  or  -K
       options.  Configuring  security  relevant  information  in the FreeIPMI configuration file
       would also be an appropriate way to hide this information.

       In order to prevent brute force attacks, some BMCs will  temporarily  "lock  up"  after  a
       number  of  remote  authentication  errors.  You  may need to wait awhile in order to this
       temporary "lock up" to pass before you may authenticate again.
