IPMI-CONFIG(8) System Commands IPMI-CONFIG(8)
NAME
ipmi-config - configure IPMI values
SYNOPSIS
ipmi-config [OPTION...]
DESCRIPTION
ipmi-config is used to get and set configuration parameters in IPMI. In
can be used to configured usernames, passwords, networking information,
security, Serial-over-LAN (SOL), Platform Event Filtering (PEF), boot
devices, power restoration policy, sensor thresholds, sensor events,
and many more configuration options.
Some configuration is typically required before most IPMI tools can be
used to access a machine remotely. By default, ipmi-config, will let
you --checkout or --commit only the core IPMI values necessary for IPMI
configuration. For additional advanced configuration fields related to
Chassis configuration (including boot options), Platform Event Filter‐
ing (PEF), or Sensors, see the --category option below.
The majority of configuration operations require ADMIN privilege when
using ipmi-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.
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 basic use of ipmi-config.
GENERAL OPTIONS
The following options are general options for configuring IPMI communi‐
cation and executing general tool commands.
-D IPMIDRIVER, --driver-type=IPMIDRIVER
Specify the driver type to use instead of doing an auto selec‐
tion. 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,
SUNBMC, and INTELDCMI.
--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)
--target-channel-number=CHANNEL-NUMBER
Specify the in-band driver target channel number to send IPMI
requests to.
--target-slave-address=SLAVE-ADDRESS
Specify the in-band driver target slave number to send IPMI
requests to.
-h IPMIHOST1,IPMIHOST2,..., --hostname=IPMIHOST1[:PORT],IPMI‐
HOST2[:PORT],...
Specify the remote host(s) to communicate with. Multiple host‐
names may be separated by comma or may be specified in a range
format; see HOSTRANGED SUPPORT below. An optional port can be
specified with each host, which may be useful in port forwarding
or similar situations.
-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 time‐
out.
-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 confidential‐
ity algorithms to use for IPMI 2.0 communication. The authenti‐
cation 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
15 - Authentication Algorithm = HMAC-SHA256; Integrity Algorithm
= None; Confidentiality Algorithm = None
16 - Authentication Algorithm = HMAC-SHA256; Integrity Algorithm
= HMAC_SHA256_128; Confidentiality Algorithm = None
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 work‐
arounds 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.
IPMI-CONFIG OPTIONS
The following options are used to read, write, and find differences in
configuration values.
-g CATEGORY, --category=CATEGORY
Specify the category or categories of configuration data to con‐
figure. Currently available choices: core, chassis, sensors,
pef, dcmi. Multiple categories can be separated by comma. core
includes all major IPMI configuration necessary to get IPMI to
function on a sytem, such as configuration for users, passwords,
authentication, networking, and serial-over-lan (SOL). chassis
includes all chassis relevant configuration including boot
options, front panel buttons, and power behavior. dcmi includes
specialized functions provided by the Data Center Management
Interface (DCMI). Defaults to core if not specified.
-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. If specified
with checkout, cannot use with multiple hosts or with
--always-prefix.
-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 speci‐
fied in a file with --filename.
-S SECTION, --section=SECTION
Specify a SECTION for checkout. This option can be used multiple
times. The SECTION you are specifying must be within the cate‐
gory or categories specified with --category.
-L, --listsections
List available sections for checkout with respect to the cate‐
gory or categories under --category. 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, addi‐
tional uncommon sections and/or fields will be shown. In the
core category, 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. In the pef category, this includes checkout out 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 iden‐
tified as unsupported on the motherboard.
--lan-channel-number=NUMBER
Use an specific channel number for LAN configuration. Particu‐
larly 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. Partic‐
ularly 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. Particu‐
larly 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 SUP‐
PORT 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 informa‐
tion.
-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 speci‐
fied, 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 lim‐
ited 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 tim‐
ing 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 com‐
municating in-band. This option is primarily useful for script‐
ing 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 specify‐
ing the configuration file with the --filename option. The configura‐
tion can be committed to multiple hosts in parallel via the hostrange
support.
Although not typically necessarily, some motherboards do not store con‐
figuration 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 will be listed on occassion in checked out files with informa‐
tion on how to configure fields. The ipmi-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.
# ipmi-config --commit -k Lan_Conf:Ip_Address=$MY_IP -k
Lan_Conf:Mac_Address=$MY_MAC --filename=my_bmc.conf
CORE 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 condi‐
tions, 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 com‐
mitted in parallel via hostrange support. Each machine must be config‐
ured with a unique IP Address and MAC Address tuple, therefore we dis‐
allow this configuration in ipmi-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 suf‐
fixed 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 respec‐
tively.
On some motherboards, configuration changes will not be "absorbed" by
the system until the motherboard is hard-reset. This can be accom‐
plished 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.
CHASSIS SPECIAL CASE CONFIGURATION INFORMATION
The Chassis_Front_Panel_Buttons:Enable_Standby_Button_For_Enter‐
ing_Standy, Chassis_Front_Panel_Buttons:Enable_Diagnostic_Inter‐
rupt_Button Chassis_Front_Panel_Buttons:Enable_Reset_Button, and Chas‐
sis_Front_Panel_Buttons:Enable_Power_Off_Button_For_Power_Off_Only
fields may not be able to be checked out on some IPMI systems, there‐
fore the checked out value may be blank. Some of these fields may be
disableable, while some are not.
The Chassis_Power_Conf:Power_Control_Interval field cannot be checked
out. Therefore the checked out value will always be blank.
PEF SPECIAL CASE CONFIGURATION INFORMATION
On some motherboards, multiple channels may exist for LAN IPMI communi‐
cation. If multiple channels exist, configuration of both channels can
be viewed and ultimately configured by running --checkout under verbose
mode. Each section name will be suffixed appropriately with the word
Channel and the channel number. For example, you might see a Commu‐
nity_String_Channel_1 and Community_String_Channel_3, where you can
configure the Community String on Channels 1 and 3 respectively.
The following are the options suitable for input for Sensor_Type in PEF
configuration.
Sensor_Type Options
Reserved, Temperature, Voltage, Current, Fan, Physical_Security,
Platform_Security_Violation_Attempt, Processor, Power_Supply,
Power_Unit, Cooling_Device, Other_Units_Based_Sensor, Memory,
Drive_Slot, Post_Memory_Resize, System_Firmware_Progress,
Event_Logging_Disabled, Watchdog1, System_Event, Critical_Inter‐
rupt, Button_Switch, Module_Board, Microcontroller_Coprocessor,
Add_In_Card, Chassis, Chip_Set, Other_FRU, Cable_Interconnect,
Terminator, System_Boot_Initiated, Boot_Error, OS_Boot, OS_Crit‐
ical_Stop, Slot_Connector, System_ACPI_Power_State, Watchdog2,
Platform_Alert, Entity_Presence, Monitor_Asic_IC, Lan, Manage‐
ment_Subsystem_Health, Battery, Session_Audit, Version_Change,
FRU_State, and Any
SENSORS SPECIAL CASE CONFIGURATION INFORMATION
Since many configurable fields involve decimal numbers, preci‐
sion/floating point inaccuracies may occur when configuring new thresh‐
olds. The inaccuracies may not be apparent immediately. It is recommend
users verify their changes after configuring new thresholds.
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 con‐
fused with regular expression character classes (also denoted by []).
For example, foo[19] does not represent foo1 or foo9, but rather repre‐
sents 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 exe‐
cuted 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 read‐
able in many situations, it may be difficult to read in other situa‐
tions. 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 hos‐
tranged 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 privi‐
lege, 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 ipmi-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 dis‐
covered 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 maxi‐
mum 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 avail‐
able 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 authen‐
ticate 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 con‐
figuration 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 informa‐
tion 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 han‐
dle 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 work‐
arounds 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 main‐
tainers on <freeipmi-users@gnu.org> or <freeipmi-devel@gnu.org>.
assumeio - This workaround flag will assume inband interfaces communi‐
cate 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.
nochecksumcheck - This workaround flag will tell FreeIPMI to not check
the checksums returned from IPMI command responses. It works around
systems that return invalid checksums due to implementation errors, but
the packet is otherwise valid. Users are cautioned on the use of this
option, as it removes validation of packet integrity in a number of
circumstances. However, it is unlikely to be an issue in most situa‐
tions. Those hitting this issue may see "connection timeout", "session
timeout", or "password verification timeout" errors. On IPMI 1.5 con‐
nections, the "noauthcodecheck" workaround may also needed too. Issue
observed on Supermicro X9SCM-iiF, Supermicro X9DRi-F, and Supermicro
X9DRFR.
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 hit‐
ting 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 authentica‐
tion 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 pro‐
tocol. 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).
noauthcodecheck - This workaround flag will tell FreeIPMI to not check
the authentication codes returned from IPMI 1.5 command responses. It
works around systems that return invalid authentication codes due to
hashing or implementation errors. Users are cautioned on the use of
this option, as it removes an authentication check verifying the valid‐
ity of a packet. However, in most organizations, this is unlikely to be
a security issue. Those hitting this issue may see "connection time‐
out", "session timeout", or "password verification timeout" errors.
Issue observed on Xyratex FB-H8-SRAY, Intel Windmill, Quanta Winter‐
fell, and Wiwynn Windmill.
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 authenti‐
cation 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-type=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 ipmi-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.
EXAMPLES
# ipmi-config --checkout
Output all core configuration information to the console. # ipmi-con‐
fig --checkout --category=pef
Output all pef configuration information to the console. # ipmi-config
--checkout --category=pef,chassis
Output all pef and chassis configuration information to the console.
# ipmi-config --checkout --filename=bmc-data1.conf
Store all core configuration information in bmc-data1.conf.
# ipmi-config --diff --filename=bmc-data2.conf
Show all difference between the current configuration and the bmc-
data2.conf file.
# ipmi-config --diff --key-pair="lan_conf_misc:gratuitous_arp_inter‐
val=8"
Show difference with the current configuration and the
'lan_conf_misc:gratuitous_arp_interval' of value '8'.
# ipmi-config --commit --filename=bmc-data1.conf
Commit all configuration values from the bmc-data1.conf file.
# ipmi-config --commit --key-pair="lan_conf_misc:gratuitous_arp_inter‐
val=4"
Commit key 'lan_conf_misc:gratuitous_arp_interval' of value '4'.
# ipmi-config --commit --filename=bmc-data-updt.conf --key-
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'.
DIAGNOSTICS
Upon successful execution, exit status is 0. On non-fatal error, exit
status is 1. On fatal error, exit status is 2.
If multiple hosts are specified for communication, the exit status is 0
if and only if all targets successfully execute. If any non-fatal error
occurs, exit status is 1. If any fatal error occurs, exit status is 2.
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 infor‐
mation.
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.
