NAME

       IPMI - IPMI Platform Event Trap Interpreter

SYNOPSIS

       ipmi-pet [OPTION...] [SPECIFIC TRAP] [VARIABLE BINDING HEX BYTES ...]

DESCRIPTION

Ipmi-pet interprets hex bytes from a platform event trap (PET) and outputs a string representing its
contents. Hex values may be input on the command line, a file via the --file option, or via stdin if
neither of the previous are specified. Ipmi-pet is commonly used in conjunction with an SNMP trap daemon
to intrepret the results from an IPMI PET trap captured by the daemon. While ipmi-pet could be called
directly from such a daemon, typically a script is called to parse the SNMP daemon's output and convert
it into a form that can be input into ipmi-pet. On some systems, you may wish to also send a PET
acknowledge to a remote system to inform it the trap was received and parsed. One can be sent using the
--pet-acknowledge option. While an IPMI session is not required to interpret a PET, data from the sensor
data repository (SDR) is required to properly interpret sensor names and other information in the PET.
IPMI session configuration below, such as driver, hostname, username, etc. should be configured to load
the SDR of the host where the trap originated. If this is difficult to perform, it may be wise to cache
and load a specific SDR cache using the --sdr-cache-file option. If the SDR is difficult to obtain, the
--ignore-sdr-cache option can be specified so that an SDR will not be loaded, and an IPMI session will
not be required. The PET will be interpreted as best as possible given no SDR. The --ignore-sdr-cache
option may affect other options such as --interpret-oem-data too. Some options, such as --manufacturer-id
and --product-id may alleviate some of these issues. If the SNMP daemon does not output a SNMPv1
specific trap on its own, it is typically output as the last element of the OID in SNMPv2. If for some
reason a specific trap cannot be determined, the value of NA may be input for the specific trap to
indicate it is not available. Ipmi-pet will output as much as possible based on the variable bindings
information. Some of the specific trap information may be obtained via SDR information.

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 IPMIHOST, --hostname=IPMIHOST[:PORT]
Specify the remote host to communicate with. An optional port can be specified, 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 OPERATOR 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.

IPMI-PET OPTIONS

The following options are specific to Ipmi-pet.

-v Output verbose output. This option will output event direction and OEM custom messages from the
trap.

-vv Output very verbose output. This option will output additional information available in the trap,
such as GUID, manufacturer ID, and system ID.

-vvv Output very 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 events.
For example, it will output Generator ID hex codes for sensors without names.

--pet-acknowledge
Send PET acknowledge using inputted trap data instead of outputting data. In some circumstances,
this may be useful to inform a remote system that a trap was received and parsed. If specified, a
hostname must be specified via -h or --hostname to inform ipmi-pet where to send the acknowledge
to. When this option is specified, the SDR cache is not loaded and is not required.

--file=CMD-FILE
Specify a file to read PET specific trap and variable bindings hex from instead of command line.

--output-event-severity
Output event severity in output. This will add an additional output of an event severity. The
outputs may be Monitor, Information, OK, Non-critical condition, Critical condition, or Non-
recoverable condition. This differs from the output of --output-event-state, as event severity is
not interpreted, it is a value reported in the SNMP trap. However, not all events may report a
severity, or some manufacturers may not support the report of a severity. Event severity will
automatically be output under verbose output.

--output-event-state
Output event state in output. This will add an additional output reporting if an event should be
viewed as NOMINAL, WARNING, or CRITICAL. This differs from the output of --output-event-severity,
as this output is an interpreted value that will be interpreted identically to the
--output-event-state output in ipmi-sel(8). As long as an event interpretation is supported, all
events will have outputted state. The event state is an interpreted value based on the
configuration file /etc/freeipmi//freeipmi_interpret_sel.conf and the event direction. See
freeipmi_interpret_sel.conf(5) for more information.

--event-state-config-file=FILE
Specify an alternate event state configuration file. Option ignored if --output-event-state not
specified.

--manufacturer-id=NUMBER
Specify a specific manufacturer id to assume. Useful if you wish to specify --interpret-oem-data,
but the manufacturer id cannot be determined by IPMI access or is not available in the SNMP trap.
The manufacturer id of a motherboard can be determined with bmc-info(8). If this option is
specified, so must --product-id.

--product-id=NUMBER
Specify a specific product id to assume. Useful if you wish to specify --interpret-oem-data, but
the product id cannot be determined by IPMI access or is not available in the SNMP trap. The
product id of a motherboard can be determined with bmc-info(8). If this option is specified, so
must --manufacturer-id.

--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".

--no-sensor-type-output
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.

--comma-separated-output
Output fields in comma separated format.

--no-header-output
Do not output column headers. May be useful in scripting.

--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).

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
cache.

-f, --flush-cache
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 system.

-Q, --quiet-cache
Do not output information about cache creation/deletion. May be useful in scripting.

--sdr-cache-recreate
If the SDR cache is out of date or invalid, automatically recreate the sensor data repository
(SDR) cache. This option may be useful for scripting purposes.

--sdr-cache-file=FILE
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.

--sdr-cache-directory=DIRECTORY
Specify an alternate directory for sensor data repository (SDR) caches to be stored or read from.
Defaults to the home directory if not specified.

--ignore-sdr-cache
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.

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.

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.

assumemaxsdrrecordcount - This workaround will inform SDR reading to stop reading after a known maximum
numer of SDR records have been read. This will work around systems that have mis-implemented SDR reading
functions that. Those hitting this issue may see "SDR record count invalid" errors. Issue observed on
unspecified Inspur motherboard.

malformedack - This workaround flag will ignore malformed PET acknowledge responses and assume any PET
acknowledge response from the remote machine is valid. It works around remote systems that respond with
PET acknowledge requests with invalid/malformed IPMI payloads. Those hitting this issue may see "session
timeout" errors when executing a PET acknowledge. Issue observed on Dell Poweredge R610.

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.

       Currently None

KNOWN ISSUES

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

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