ipmi-sel - display SEL entries
is used to view and manage System Event Log (SEL) entries. SEL
records store system event information and may be useful for debugging
does not inform the user if an event is particularly good or bad, just
that the event occurred. Users may wish to use the
--output-event-state option to output the analyzed state.
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
To perform some advanced SEL management, please see
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, SUNBMC, and INTELDCMI.
Do not probe in-band IPMI devices for default settings.
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.
Specify the in-band driver device path to be used instead of the
Specify the in-band driver register spacing instead of the probed
value. Argument is in bytes (i.e. 32bit register spacing = 4)
Specify the in-band driver target channel number to send IPMI requests
Specify the in-band driver target slave number to send IPMI requests
-h IPMIHOST1,IPMIHOST2,..., --hostname=IPMIHOST1[:PORT],IPMIHOST2[:PORT],...
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. An optional port can be specified with each
host, which may be useful in port forwarding or similar situations.
If specifying an IPv6 address and port, use the format [ADDRESS]:PORT.
- -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 USER privileges in order for this tool to
- -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
- -K, --k-g-prompt
Prompt for k-g to avoid possibility of listing it in process lists.
Specify the session timeout in milliseconds. Defaults to 20000
milliseconds (20 seconds) if not specified.
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
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 OPERATOR
if not specified.
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
Turn on debugging.
- -?, --help
Output a help list and exit.
Output a usage message and exit.
- -V, --version
Output the program version and exit.
The following options are specific to
Output verbose output. This option will output event direction.
Event direction may be useful to differentiate severity between some
events. For example, some motherboards may issue an event both when a
temperature exceeds a threshold and when it goes back down below it.
Output very verbose output. This option will output additional
information than verbose output. Most notably it will output
additional hex codes to given information on ambiguous SEL entries,
such as OEM codes. For example, it will output Generator ID hex codes
for sensors without names, event type codes for OEM events, and record
types for OEM records. This information may be useful if you are
writing a parser outside of
to interpret OEM information.
- -i, --info
Show general information about the SEL.
Display SEL records by record id. Accepts space or comma separated lists.
Exclude display of SEL records by record id. Accepts space or comma
Display SEL records from record id START to END.
Exclude display of SEL records from record id START to END.
Display SEL records with events occurring in the specified date range.
Dates may be specified in MM/DD/YYYY, MM-DD-YYYY or the ISO 8601
YYYY-MM-DDTHH:MM:SS format. For the non ISO 8601 formats, the month
may be specified as a numeral or its abbreviated string name. The
current local system time can be specified with "now". Note that
non-timestamped records will not be displayed automatically because
they do not possess a timestamp.
Exclude display of SEL records with events occurring in the specified
date range. Dates may be specified in MM/DD/YYYY, MM-DD-YYYY or the
ISO 8601 YYYY-MM-DDTHH:MM:SS format. For the non ISO 8601 formats,
the month may be specified as a numeral or its abbreviated string
name. The current local system time can be specified with "now".
Note that non-timestamped records will be displayed automatically
because they do not possess a timestamp.
- -t SENSOR-TYPE-LIST, --sensor-types=SENSOR-TYPE-LIST
Specify sensor types to show SEL events for. Multiple types can be
separated by commas or spaces. A special command line type of "all",
will indicate all types should be shown (may be useful for overriding
configured defaults). Users may specify sensor types by string (see
--list-sensor-types below) or by number (decimal or hex).
- -T SENSOR-TYPE-LIST, --exclude-sensor-types=SENSOR-TYPE-LIST
Specify sensor types to not show SEL events for. Multiple types can
be separated by commas or spaces. A special command line type of "none",
will indicate no types should be excluded (may be useful for
overriding configured defaults). Users may specify sensor types by
string (see --list-sensor-types below) or by number (decimal
- -L, --list-sensor-types
List sensor types.
Display approximately the last count SEL records. The display
count is calculated by approximating the record ids of the last SEL
records. It's correctness depends highly on the SEL implementation by
Identical to --clear, except the SEL clearing will be
performed after SEL event records are displayed. This option is
useful for scripting if users intend to log SEL events to another log,
then immediately clear SEL. Unlike calling --clear in another
this option will use SEL reservations to notify the user if a SEL
change has occurred while displaying and clearing the SEL. This can
protect users from a race, where a new SEL event is unknowingly
generated before clearing the SEL. Note that SEL reservations are
optionally implemented by vendors and may not be available on all
Delete records by record id in the SEL. Accepts space or comma
Delete record ids from START to END in the SEL.
Output only system event records (i.e. don't output OEM records).
Output only OEM event records (i.e. don't output system event records).
For OEM SEL record types, output the manufacturer ID along with event
data when available.
Output event state in output. This will add an additional output
reporting if an event should be viewed as NOMINAL, WARNING, or CRITICAL.
The event state is an interpreted value based on the configuration
file /etc/freeipmi//freeipmi_interpret_sel.conf and the event direction.
for more information.
Specify an alternate event state configuration file. Option ignored
if --output-event-state not specified.
Hex-dump SEL entries.
Attempt to interpret OEM data, such as event data, sensor readings, or
general extra info, etc. If an OEM interpretation is not available,
the default output will be generated. Correctness of OEM
interpretations cannot be guaranteed due to potential changes OEM
vendors may make in products, firmware, etc. See OEM INTERPRETATION
below for confirmed supported motherboard interpretations.
Some motherboards support an IPMI OEM extension that returns the
string output for a system event. Such string output may be
beneficial for determining the meaning behind OEM specific events. This option
will use the OEM event string to describe all system events in the
output. This option differs from --interpret-oem-data
option in that all system events will output the vendor supplied event
string, not just events that are OEM specific. The event string may
be very different from the normal FreeIPMI event string output. If an
OEM event strings is not available, the default output will be output.
This option is confirmed to work for Fujitsu iRMC S1 and iRMC S2
Output sensor names prefixed with their entity id and instance number
when appropriate. This may be necessary on some motherboards to help
identify what sensors are referencing. For example, a motherboard may
have multiple sensors named 'TEMP'. The entity id and instance number
may help clarify which sensor refers to "Processor 1" vs. "Processor
Do not show sensor type output for each entry. On many systems, the
sensor type is redundant to the name of the sensor. This can
especially be true if --entity-sensor-names is specified.
If the sensor name is sufficient, or if the sensor type is of no
interest to the user, this option can be specified to condense output.
Output fields in comma separated format.
Do not output column headers. May be useful in scripting.
Output non-abbreviated units (e.g. 'Amps' instead of 'A'). May aid in
disambiguation of units (e.g. 'C' for Celsius or Coulombs).
Output in legacy format. Newer options may not be applicable to
SDR CACHE OPTIONS
This tool requires access to the sensor data repository (SDR) cache
for general operation. By default, SDR data will be downloaded and
cached on the local machine. The following options apply to the SDR
Flush a cached version of the sensor data repository (SDR) cache. The
SDR is typically cached for faster subsequent access. However, it may
need to be flushed and re-generated if the SDR has been updated on a
Do not output information about cache creation/deletion. May be
useful in scripting.
If the SDR cache is out of date or invalid, automatically recreate the
sensor data repository (SDR) cache. This option may be useful for
Specify a specific sensor data repository (SDR) cache file to be
stored or read from. If this option is used when multiple hosts are
specified, the same SDR cache file will be used for all hosts.
Specify an alternate directory for sensor data repository (SDR) caches
to be stored or read from. Defaults to the home directory if not
Ignore SDR cache related processing. May lead to incomplete or less
useful information being output, however it will allow functionality
for systems without SDRs or when the correct SDR cannot be loaded.
By IPMI definition, all IPMI times and timestamps are stored in
localtime. However, in many situations, the timestamps will not be
stored in localtime. Whether or not a system truly stored the
timestamps in localtime varies on many factors, such as the vendor,
BIOS, and operating system.
The following options will allow the user to adjust the interpretation
of the stored timestamps and how they should be output.
Assume all times are reported in UTC time and convert the time to
localtime before being output.
Convert all localtime timestamps to UTC before being output.
Specify a specific UTC offset in seconds to be added to timestamps.
Value can range from -86400 to 86400 seconds. Defaults to 0.
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
- -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
This attempts to remove the common issue of hostranged execution
timing out due to several nodes being removed from service in a large
daemon must be running on the node executing the command.
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.
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 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
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
In-band IPMI Communication will be used when the host "localhost" is
specified. This allows the user to add the localhost into the
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
tool can be used to check and/or change these configuration
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 <email@example.com>
"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
"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
"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
"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.
"internal IPMI error" - An IPMI error has occurred that FreeIPMI does
not know how to handle. Please e-mail <firstname.lastname@example.org> to
report the issue.
Some timestamps in the SEL may report a date of 1-Jan-1970, the epoch
for SEL timestamps. This timestamp is not necessarily incorrect. It
usually indicates a hardware event that occurred before a timestamp in
firmware has been initialized. For example, certain hardware
components will have their internal clocks reset during a power cycle.
However, if the internal clock of the SEL appears to be regularly
incorrect, you may need to set the SEL time. This can be done using
The following are common SEL related messages.
"sel config file parse error" - A parse error was found in the sel
event interpretation configuration file. Please see
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
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
If you believe your hardware has an additional compliance issue that
needs a workaround to be implemented, please contact the FreeIPMI
maintainers on <email@example.com> or <firstname.lastname@example.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.
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 situations. Those hitting this issue may see "connection
timeout", "session timeout", or "password verification timeout"
errors. On IPMI 1.5 connections, 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
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
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 validity of a packet. However, in most organizations,
this is unlikely to be a security issue. Those hitting this issue may
see "connection timeout", "session timeout", or "password verification
timeout" errors. Issue observed on Xyratex FB-H8-SRAY, Intel
Windmill, Quanta Winterfell, 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
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, Quanta QSSC-S4R/Appro GB812X-CN,
and Dell C5220. This workaround is automatically triggered with the
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.
assumemaxsdrrecordcount - This workaround will inform SDR
reading to stop reading after a known maximum number of SDR records
have been read. This will work around systems that have
miss-implemented SDR reading functions. Those hitting this issue may
see "SDR record count invalid" errors. Issue observed on unspecified
assumesystemevent - This workaround option will assume invalid SEL
record types are system event records. Records may be formatted
correctly but report invalid record types. Those hitting this issue
may see "Unknown SEL Record Type" errors. Output may be unknown, pray
for the best. This option is confirmed to work around compliances
issues on HP DL 380 G5 motherboards.
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 a number of
HP and Supermicro motherboards.
The following motherboards are confirmed to have atleast some support
by the --interpret-oem-data option. While highly probable the
OEM data interpretations would work across other motherboards by the
same manufacturer, there are no guarantees. Some of the motherboards
below may be rebranded by vendors/distributors.

Upon successful execution, exit status is 0. On error, exit status is
If multiple hosts are specified for communication, the exit status
is 0 if and only if all targets successfully execute. Otherwise the
exit status is 1.
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
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.
