NAME
ipmiseld - IPMI SEL logging daemon
SYNOPSIS
ipmiseld [OPTION...]
DESCRIPTION
The ipmiseld daemon polls the system event log (SEL) of specified hosts and stores the logs into the
local syslog. By default, the daemon can also make best efforts to manage the remote SEL's buffer to
ensure events are never lost. Recent logging data will be cached to disk to ensure that SEL events are
not missed in the event the client or server is rebooted.
Many of the options for this daemon are very similar to the ipmi-sel(8) tool. It can be configured to log
the local host, a remote host, or a range of hosts to the local syslog. It can be configured via the
command line arguments listed below or via the /etc/freeipmi//ipmiseld.conf configuration file.
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).
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, 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],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.
-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 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

= 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.
--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.
IPMISELD OPTIONS
The following options are specific to Ipmiseld.
-v Log verbose information. This option will log additional information. Most notably it will output
additional hex codes to given information on ambiguous SEL entries or SEL records. For example, it
will output Generator ID hex codes for sensors without names. Additional non-critical SEL errors
or issues will also be logged. Somewhat common errors, such as timeouts or invalid hostnames, will
output with increased verbosity.
-t SENSOR-TYPE-LIST, --sensor-types=SENSOR-TYPE-LIST
Specify sensor types of SEL events to log. By default, all sensor types are logged. A special
command line type of "all", will indicate all types should be shown (may be useful for overriding
configured defaults). Multiple types can be separated by commas or spaces. Users may specify
sensor types by string (see --list-sensor-types in ipmi-sel(8)) or by number (decimal or hex).
-T SENSOR-TYPE-LIST, --exclude-sensor-types=SENSOR-TYPE-LIST
Specify sensor types of SEL events to not log. By default, no sensor types are filtered. A special
command line type of "none", will indicate no types should be excluded (may be useful for
overriding configured defaults). Multiple types can be separated by commas or spaces. Users may
specify sensor types by string (see --list-sensor-types in ipmi-sel(8)) or by number (decimal or
hex).
--system-event-only
Log only system event records (i.e. don't log OEM records).
--oem-event-only
Log only OEM event records (i.e. don't log system event records).
--event-state-config-file=FILE
Specify an alternate event state configuration file.
--interpret-oem-data
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.
--entity-sensor-names
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 2".
--non-abbreviated-units
Output non-abbreviated units (e.g. 'Amps' instead of 'A'). May aid in disambiguation of units
(e.g. 'C' for Celsius or Coulombs).
--event-state-filter=FILTERSTRING
Specify event states to be filtered out and not logged. Possible inputs are NOMINAL, WARNING,
CRITICAL, and NA. Multiple states can be listed separted by comma. The special case string of
"none" will indicate no event states should be excluded (may be useful for overriding configured
defaults).
--warning-threshold=PERCENTINT
Specify SEL fullness warning threshold as an integer percentage. When the SEL is past this
percentage full, a warning will be output indicating that SEL is nearly full. Specify 0 to disable
warning logs. Defaults to 80.
--clear-threshold=PERCENTINT
Specify SEL fullness clear threshold as an integer percentage. When the SEL is past this
percentage full, ipmiseld will attempt to clear the SEL. Specify 0 to disable clearing. When the
SEL is full, it will be the responsibility of the user to clear the SEL manually if clearing is
disabled. Defaults to 0. If specified to a non-zero value, be careful that the clearing of the SEL
could affect other applications that monitor the SEL, such as monitoring applications that use
ipmi-sel(8) or libipmimonitoring(3).
--system-event-format=FORMATSTRING
Specify the format of the log output when a SEL system event is encountered. Defaults to "SEL
System Event: %d, %t, %s, %I, %E" if logging locally, "SEL System Event(%h): %d, %t, %s, %I, %E"
if logging outofband or with hostranges. See SEL LOG FORMAT STRING below for formatting details.
--oem-timestamped-event-format=FORMATSTRING
Specify the format of the log output when a SEL OEM timestamped event is encountered. Defaults to
"SEL OEM Event: %d, %t, %I, %o" if logging locally, "SEL OEM Event(%h): %d, %t, %I, %o" if logging
outofband or with hostranges.. See SEL LOG FORMAT STRING below for formatting details.
--oem-non-timestamped-event-format=FORMATSTRING
Specify the format of the log output when a SEL OEM non-timestamped event is encountered. Defaults
to "SEL OEM Event: %I, %o" if logging locally, "SEL OEM Event(%h): %I, %o" if logging outofband or
with hostranges.. See SEL LOG FORMAT STRING below for formatting details.
--poll-interval=SECONDS
Specify the poll interval to check the SEL for new events. Defaults to 300 seconds (i.e. 5
minutes).
--log-facility=STRING
Specify the log facility to use. Defaults to LOG_DAEMON. Legal inputs are LOG_DAEMON, LOG_USER,
LOG_LOCAL0, LOG_LOCAL1, LOG_LOCAL2, LOG_LOCAL3, LOG_LOCAL4, LOG_LOCAL5, LOG_LOCAL6, LOG_LOCAL7.
--log-priority=STRING
Specify the log priority to use. Defaults to LOG_ERR. Legal inputs are LOG_EMERG, LOG_ALERT,
LOG_CRIT, LOG_ERR, LOG_WARNING, LOG_NOTICE, LOG_INFO, LOG_DEBUG.
--cache-directory=DIRECTORY
Specify an alternate cache directory location for ipmiseld to use. The cache directory will be
used to cache a wide variety of data, including the SDR and recent logging information to ensure
log entries are not missed on reboots and other system failures.
--ignore-sdr
Ignore SDR 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.
--re-download-sdr
Re-download the SDR on start even if it is not out of date. This may help work around systems that
do not properly timestamp SDR modification times.
--clear-sel
On startup, clear any SEL being monitored. May be useful the first time running ipmiseld to avoid
warning messages or SEL clears until a long time in the future.
--threadpool-count=NUM
Specify the number of threads for parallel SEL polling. This option is very similar to the
--fanout option in ipmi-sel(8) but the threads are created only once on initialization for faster
processing. Defaults to 8, however the threadpool count will always be decreased if the number of
nodes specified is less than the number of threads.
--test-run
Do not daemonize, output the current SEL of configured hosts as a test of current settings and
configuration.
--foreground
Run daemon in the foreground.
SEL LOG FORMAT STRING
The output format of log messages can be adjusted via the --system-event-format,
--oem-timestamped-event-format and --oem-non-timestamped-event-format options. Options such as
--interpret-oem-data, --entity-sensor-names, and --non-abbreviated-units can further adjust the output
format. The following conversion directives will allow the user to output specifics of each SEL event
that occurs.
For System, OEM timestamped, and OEM non-timestamped events
%h - target host, useful if logging from multiple hosts
%i - record ID in decimal
%I - event state interpretation (NOMINAL, WARNING, or CRITICAL)
For System and OEM timestamped events
%t - time in format H:M:S using 24 hour clock
%d - date in format D-M-YEAR
For System events
%T - sensor type
%s - sensor name
%e - event data 1 string
%f - event data 2 string [2]
%h - event data 3 string
%c - combined event data 2 and event data 3 string
%p - event data 2 previous state string
%S - event data 2 severity string
%E - combined event data 1, 2, and 3 string
%k - event direction
For OEM timestamped events
%m - manufacturer id
For OEM timestamped and OEM non-timestamped events
%o - oem data in hex
%O - OEM supplied string describing the event (depends on manufacturer)
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.
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 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 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.
"internal IPMI error" - An IPMI error has occurred that FreeIPMI does not know how to handle. Please e-
mail <freeipmi-users@gnu.org> to report the issue.
IPMISELD TROUBLESHOOTING
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 bmc-device(8).
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 freeipmi_interpret_sel.conf(5).
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.
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 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).
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, 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.
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 HP Proliant DL 145.
OEM INTERPRETATION
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.

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
