ipmiseld(8)ipmiseldipmiseld(8)NAMEipmiseld - IPMI SEL logging daemon
SYNOPSISipmiseld [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 com‐
mand line arguments listed below or via the
/usr/local/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 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 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 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
OPERATOR 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.
IPMISELD OPTIONS
The following options are specific to Ipmiseld.
-v Log verbose information. This option will log additional infor‐
mation. 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 with‐
out 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 sen‐
sor 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 sepa‐
rated 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 read‐
ings, 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 inter‐
pretations.
--entity-sensor-names
Output sensor names prefixed with their entity id and instance
number when appropriate. This may be necessary on some mother‐
boards to help identify what sensors are referencing. For exam‐
ple, 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 monitor‐
ing 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-times‐
tamped event is encountered. Defaults to "SEL OEM Event: %I, %o"
if logging locally, "SEL OEM Event(%h): %I, %o" if logging out‐
ofband 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 function‐
ality 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 --sys‐
tem-event-format, --oem-timestamped-event-format and --oem-non-times‐
tamped-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 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.
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.
"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_inter‐
pret_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 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.
assumesystemevent - This workaround option will assume invalid SEL
record types are system event records. Records may be formatted cor‐
rectly 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 manu‐
facturer, 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 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.
