DESCRIPTION

This program lets you manage Intelligent Platform Management Interface (IPMI) functions of either the local system, via a kernel device driver, or a remote system, using IPMI v1.5 and IPMI v2.0. These functions include printing FRU information, LAN configuration, sensor readings, and remote chassis power control.

IPMI management of a local system interface requires a compatible IPMI kernel driver to be installed and configured. On Linux this driver is called OpenIPMI and it is included in standard distributions. On Solaris this driver is called BMC and is inclued in Solaris 10. Management of a remote station requires the IPMI-over-LAN interface to be enabled and configured. Depending on the particular requirements of each system it may be possible to enable the LAN interface using ipmitool over the system interface.

OPTIONS

Prompt for the remote server password.
Specify an authentication type to use during IPMIv1.5 lan session activation. Supported types are NONE, PASSWORD, MD2, MD5, or OEM.
Set destination channel for bridged request.
Set transit channel for bridged request (dual bridge).
Set destination channel for bridged request.
Set transit channel for bridged request. (dual bridge)
Present output in CSV (comma separated variable) format. This is not available with all commands.
The remote server authentication, integrity, and encryption algorithms to use for IPMIv2.0 lanplus connections. See table 22-19 in the IPMIv2.0 specification. The default is 3 which specifies RAKP-HMAC-SHA1 authentication, HMAC-SHA1-96 integrity, and AES-CBC-128 encryption algorithms.
Use device number N to specify the /dev/ipmiN (or /dev/ipmi/N or /dev/ipmidev/N) device to use for in-band BMC communication. Used to target a specific BMC on a multi-node, multi-BMC system through the ipmi device driver interface. Default is 0.
Use supplied character for SOL session escape character. The default is to use ~ but this can conflict with ssh sessions.
The remote server password is specified by the environment variable IPMI_PASSWORD or IPMITOOL_PASSWORD. The IPMITOOL_PASSWORD takes precedence.
Specifies a file containing the remote server password. If this option is absent, or if password_file is empty, the password will default to NULL.
Deprecated. Use: -o intelplus
Get basic usage help from the command line.
Remote server address, can be IP address or hostname. This option is required for lan and lanplus interfaces.
Selects IPMI interface to use. Supported interfaces that are compiled in are visible in the usage help output.
Use supplied Kg key for IPMIv2.0 authentication. The default is not to use any Kg key.
Read Kg key from IPMITOOL_KGKEY or IPMI_KGKEY environment variable. IPMITOOL_KGKEY takes precedence.
Set destination lun for raw commands.
Force session privilege level. Can be CALLBACK, USER, OPERATOR, ADMINISTRATOR. Default is ADMINISTRATOR. This value is ignored and always set to ADMINISTRATOR when combined with -t target address.
Set the local IPMB address. The local address defaults to 0x20 or is auto discovered on PICMG platforms when -m is not specified. There should be no need to change the local address for normal operation.
Specify nr. of seconds between retransmissions of lan/lanplus messages. Defaults are 2 seconds for lan and 1 second for lanplus interfaces. Command raw uses fixed value of 15 seconds. Command sol uses fixed value of 1 second.
Select OEM type to support. This usually involves minor hacks in place in the code to work around quirks in various BMCs from various manufacturers. Use -o list to see a list of current supported OEM types.
Open selected file and read OEM SEL event descriptions to be used during SEL listings. See examples in contrib dir for file format.
Remote server UDP port to connect to. Default is 623.
Remote server password is specified on the command line. If supported it will be obscured in the process list. Note! Specifying the password as a command line option is not recommended.
Set the number of retries for lan/lanplus interface (default=4). Command raw uses fixed value of one try (no retries). Command hpm uses fixed value of 10 retries.
Deprecated. Use: -o supermicro
Use local file for remote SDR cache. Using a local SDR cache can drastically increase performance for commands that require knowledge of the entire SDR to perform their function. Local SDR cache from a remote system can be created with the sdr dump command.
Bridge IPMI requests to the remote target address. Default is 32. The -L privlvl option is always ignored and value set to ADMINISTRATOR.
Set transit address for bridge request (dual bridge).
Set transit address for bridge request. (dual bridge)
Remote server username, default is NULL user.
Increase verbose output level. This option may be specified multiple times to increase the level of debug output. If given three times you will get hexdumps of all incoming and outgoing packets. Using it five times provides details on request and expected reply procesing. The hpm commands targetcap compprop abort upgstatus rollback rollbackstatus selftestresult increases the verbosity level
Display version information.
Use supplied Kg key for IPMIv2.0 authentication. The key is expected in hexadecimal format and can be used to specify keys with non-printable characters. E.g. '-k PASSWORD' and '-y 50415353574F5244' are equivalent. The default is not to use any Kg key.
Prompt for the Kg key for IPMIv2.0 authentication.
Change Size of Communication Channel. (OEM)

If no password method is specified then ipmitool will prompt the user for a password. If no password is entered at the prompt, the remote server password will default to NULL.

All the above options may be specified using environment variable. Either IPMITOOL_OPTS or IPMI_OPTS. IPMITOOL_OPTS takes precedence.

SECURITY

There are several security issues be be considered before enabling the IPMI LAN interface. A remote station has the ability to control a system's power state as well as being able to gather certain platform information. To reduce vulnerability it is strongly advised that the IPMI LAN interface only be enabled in 'trusted' environments where system security is not an issue or where there is a dedicated secure 'management network'.

Further it is strongly advised that you should not enable IPMI for remote access without setting a password, and that that password should not be the same as any other password on that system.

When an IPMI password is changed on a remote machine with the IPMIv1.5 lan interface the new password is sent across the network as clear text. This could be observed and then used to attack the remote system. It is thus recommended that IPMI password management only be done over IPMIv2.0 lanplus interface or the system interface on the local station.

For IPMI v1.5, the maximum password length is 16 characters. Passwords longer than 16 characters will be truncated.

For IPMI v2.0, the maximum password length is 20 characters; longer passwords are truncated.

<predefined event number N>

Send a pre-defined test event to the System Event Log. The following events are included as a means to test the functionality of the System Event Log component of the BMC (an entry will be added each time the event N command is executed).

Currently supported values for N are:
1 Temperature: Upper Critical: Going High
2 Voltage Threshold: Lower Critical: Going Low
3 Memory: Correctable ECC

NOTE: These pre-defined events will likely not produce "accurate" SEL records for a particular system because they will not be correctly tied to a valid sensor number, but they are sufficient to verify correct operation of the SEL.

Event log records specified in <filename> will be added to the System Event Log.

The format of each line in the file is as follows:

<{EvM Revision} {Sensor Type} {Sensor Num} {Event Dir/Type} {Event Data 0} {Event Data 1} {Event Data 2}>[# COMMENT]

e.g.: 0x4 0x2 0x60 0x1 0x52 0x0 0x0 # Voltage threshold: Lower Critical: Going Low

EvM Revision - The "Event Message Revision" is 0x04 for messages that comply with the IPMI 2.0 Specification and 0x03 for messages that comply with the IPMI 1.0 Specification.

Sensor Type - Indicates the Event Type or Class.

Sensor Num - Represents the 'sensor' within the management controller that generated the Event Message.

Event Dir/Type - This field is encoded with the event direction as the high bit (bit 7) and the event type as the low 7 bits. Event direction is 0 for an assertion event and 1 for a deassertion event.

See the IPMI 2.0 specification for further details on the definitions for each field.

<sensorid> <list>

Get a list of all the possible Sensor States and pre-defined Sensor State Shortcuts available for a particular sensor. sensorid is the character string representation of the sensor and must be enclosed in double quotes if it includes white space. Several different commands including ipmitool sensor list may be used to obtain a list that includes the sensorid strings representing the sensors on a given system.

> ipmitool -I open event "PS 2T Fan Fault" list
Finding sensor PS 2T Fan Fault... ok
Sensor States:
State Deasserted
State Asserted
Sensor State Shortcuts:
present absent
assert deassert
limit nolimit
fail nofail
yes no
on off
up down

<sensorid> <sensor state> [<direction>]

Generate a custom event based on existing sensor information. The optional event direction can be either assert (the default) or deassert.

> ipmitool event "PS 2T Fan Fault" "State Asserted"
Finding sensor PS 2T Fan Fault... ok
0 | Pre-Init Time-stamp | Fan PS 2T Fan Fault | State Asserted

> ipmitool event "PS 2T Fan Fault" "State Deasserted"
Finding sensor PS 2T Fan Fault... ok
0 | Pre-Init Time-stamp | Fan PS 2T Fan Fault | State Desserted

Execute ipmitool commands from filename. Each line is a complete command. The syntax of the commands are defined by the COMMANDS section in this manpage. Each line may have an optional comment at the end of the line, delimited with a `#' symbol.

e.g., a command file with two lines:

sdr list # get a list of sdr records
sel list # get a list of sel records

This command supports the Firmware Firewall capability. It may be used to add or remove security-based restrictions on certain commands/command sub-functions or to list the current firmware firewall restrictions set on any commands. For each firmware firewall command listed below, parameters may be included to cause the command to be executed with increasing granularity on a specific LUN, for a specific NetFn, for a specific IPMI Command, and finally for a specific command's sub-function (see Appendix H in the IPMI 2.0 Specification for a listing of any sub-function numbers that may be associated with a particular command).

Parameter syntax and dependencies are as follows:

[<channel H>] [<lun L> [ <netfn N> [<command C [<subfn S>]]]]

Note that if "netfn <N>" is specified, then "lun <L>" must also be specified; if "command <C>" is specified, then "netfn <N>" (and therefore "lun <L>") must also be specified, and so forth.

"channel <H>" is an optional and standalone parameter. If not specified, the requested operation will be performed on the current channel. Note that command support may vary from channel to channel.

Firmware firewall commands:

List firmware firewall information for the specified LUN, NetFn, and Command (if supplied) on the current or specified channel. Listed information includes the support, configurable, and enabled bits for the specified command or commands.

Some usage examples:

This command will list firmware firewall information for all NetFns for the specified LUN on either the current or the specified channel.

This command will print out all command information for a single LUN/NetFn pair.

This prints out detailed, human-readable information showing the support, configurable, and enabled bits for the specified command on the specified LUN/NetFn pair. Information will be printed about each of the command subfunctions.

Print out information for a specific sub-function.

This command is used to enable commands for a given NetFn/LUN combination on the specified channel.

This command is used to disable commands for a given NetFn/LUN combination on the specified channel. Great care should be taken if using the "force" option so as not to disable the "Set Command Enables" command.

This command may be used to reset the firmware firewall back to a state where all commands and command sub-functions are enabled.

Read all Field Replaceable Unit (FRU) inventory data and extract such information as serial number, part number, asset tags, and short strings describing the chassis, board, or product.

fru id is the digit ID of the FRU (see output of 'fru print'). fru file is the absolute pathname of a file in which to dump the binary FRU data pertaining to the specified FRU entity.

fru id is the digit ID of the FRU (see output of 'fru print'). fru file is the absolute pathname of a file from which to pull the binary FRU data before uploading it to the specified FRU.

Update a multirecord FRU location. fru id is the digit ID of the FRU (see output of 'fru print'). fru file is the absolute pathname of a file from which to pull the binary FRU data to upload into the specified multirecord FRU entity.

This command provides interactive editing of some supported records, namely PICMG Carrier Activation Record. fru id is the digit ID of the FRU (see output of 'fru print'); default is 0.

This command may be used to set a field string to a new value. It replaces the FRU data found at index in the specified section with the supplied string.

<section> is a string which refers to FRU Inventory Information
Storage Areas and may be refer to:



<index> specifies the field number. Field numbering starts on the first 'english text' field type. For instance in the <board> info area field '0' is <Board Manufacturer> and field '2' is <Board Serial Number>; see IPMI Platform Management FRU Information Storage Definition v1.0 R1.1 for field locations.

<string> must be the same length as the string being replaced and must be 8-bit ASCII (0xCx).

This command edits the data found in the multirecord area. Support for OEM specific records is limited.

These commands will allow you to configure IPMI LAN channels with network information so they can be used with the ipmitool lan and lanplus interfaces. NOTE: To determine on which channel the LAN interface is located, issue the `channel info number' command until you come across a valid 802.3 LAN channel. For example:

> ipmitool -I open channel info 1
Channel 0x1 info:
Channel Medium Type : 802.3 LAN
Channel Protocol Type : IPMB-1.0
Session Support : session-based
Active Session Count : 8
Protocol Vendor ID : 7154

Print the current configuration for the given channel. The default will print information on the first found LAN channel.

Set the given command and parameter on the specified channel. Valid command/parameter options are:

Set the IP address for this channel.

Set the netmask for this channel.

Set the MAC address for this channel.

Set the default gateway IP address.

Correlates cipher suite numbers with the maximum privilege level that is allowed to use it. In this way, cipher suites can restricted to users with a given privilege level, so that, for example, administrators are required to use a stronger cipher suite than normal users.

The format of privlist is as follows. Each character represents a privilege level and the character position identifies the cipher suite number. For example, the first character represents cipher suite 0, the second represents cipher suite 1, and so on. privlist must be 15 characters in length.

Characters used in privlist and their associated privilege levels are:

X Cipher Suite Unused
c CALLBACK
u USER
o OPERATOR
a ADMIN
O OEM

So, to set the maximum privilege for cipher suite 0 to USER and suite 1 to ADMIN, issue the following command:

> ipmitool -I interface lan set channel cipher_privs uaXXXXXXXXXXXXX

Print alert information for the specified channel and destination. The default will print all alerts for all alert destinations on the first found LAN channel.

This command lists the PEF policy table entries. Each policy entry describes an alert destination. A policy set is a collection of table entries. PEF alert actions reference policy sets.

This command lists the PEF table entries. Each PEF entry relates a sensor event to an action. When PEF is active, each platform event causes the BMC to scan this table for entries matching the event, and possible actions to be taken. Actions are performed in priority order (higher criticality first).

Run a PICMG/ATA extended command. Get PICMG properties may be used to obtain and print Extension major version information, PICMG identifier, FRU Device ID and Max FRU Device ID.

This will allow you to execute raw IPMI commands. For example to query the POH counter with a raw command:

> ipmitool -v raw 0x0 0xf
RAW REQ (netfn=0x0 cmd=0xf data_len=0)
RAW RSP (5 bytes)
3c 72 0c 00 00

Note that the OpenIPMI driver provided by the Linux kernel will reject the Get Message, Send Message and Read Event Message Buffer commands because it handles the message sequencing internally.


Prints information for sensor data records specified by sensor id.

This command will query the BMC for Sensor Data Record (SDR) Repository information.

This command will display all records from the SDR Repository of a specific type. Run with type list (or simply with no type) to see the list of available types. For example to query for all Temperature sensors:

> ipmitool sdr type Temperature
Baseboard Temp | 30h | ok | 7.1 | 28 degrees C
FntPnl Amb Temp | 32h | ok | 12.1 | 24 degrees C
Processor1 Temp | 98h | ok | 3.1 | 57 degrees C
Processor2 Temp | 99h | ok | 3.2 | 53 degrees C

This command will read the Sensor Data Records (SDR) and extract sensor information of a given type, then query each sensor and print its name, reading, and status. If invoked as elist then it will also print sensor number, entity id and instance, and asserted discrete states.

The default output will only display full and compact sensor types, to see all sensors use the all type with this command.

All SDR records (Sensor and Locator)

Full Sensor Record

Compact Sensor Record

Event-Only Sensor Record

Management Controller Locator Record

FRU Locator Record

Generic SDR records

Displays all sensors associated with an entity. Get a list of valid entity ids on the target system by issuing the sdr elist command. A list of all entity ids can be found in the IPMI specifications.

Dumps raw SDR data to a file. This data file can then be used as a local SDR cache of the remote managed system with the -S <file> option on the ipmitool command line. This can greatly improve performance over system interface or remote LAN.

Create the SDR Repository for the current configuration. Will perform a 'Clear SDR Repository' command so be careful.

Fill the SDR Repository using records stored in a binary data file. Will perform a 'Clear SDR Repository' command so be careful.

NOTE: System Event Log (SEL) entry-times are displayed as `Pre-Init Time-stamp' if the SEL clock needs to be set. Ensure that the SEL clock is accurate by invoking the sel time get and sel time set <time string> commands.

This command will query the BMC for information about the System Event Log (SEL) and its contents.

This command will clear the contents of the SEL. It cannot be undone so be careful.

When this command is invoked without arguments, the entire contents of the System Event Log are displayed. If invoked as elist (extended list) it will also use the Sensor Data Record entries to display the sensor ID for the sensor that caused each event. Note this can take a long time over the system interface.

<count> | first <count>

Displays the first count (least-recent) entries in the SEL. If count is zero, all entries are displayed.

Displays the last count (most-recent) entries in the SEL. If count is zero, all entries are displayed.

Delete one or more SEL event records.

Read event entries from a file and add them to the SEL. New SEL entries area added onto the SEL after the last record in the SEL. Record added is of type 2 and is automatically timestamped.

Print information on the specified SEL Record entry.

Save SEL records to a text file that can be fed back into the event file ipmitool command. This can be useful for testing Event generation by building an appropriate Platform Event Message file based on existing events. Please see the available help for the 'event file ...' command for a description of the format of this file.

Save SEL records to a file in raw, binary format. This file can be fed back to the sel readraw ipmitool command for viewing.

Read and display SEL records from a binary file. Such a file can be created using the sel writeraw ipmitool command.


Displays the SEL clock's current time.

Sets the SEL clock. Future SEL entries will use the time set by this command. <time string> is of the form "MM/DD/YYYY HH:MM:SS". Note that hours are in 24-hour form. It is recommended that the SEL be cleared before setting the time.

Lists sensors and thresholds in a wide table format.

Prints information for sensors specified by name.

This allows you to set a particular sensor threshold value. The sensor is specified by name.


unr Upper Non-Recoverable
ucr Upper Critical
unc Upper Non-Critical
lnc Lower Non-Critical
lcr Lower Critical
lnr Lower Non-Recoverable

This allows you to set all lower thresholds for a sensor at the same time. The sensor is specified by name and the thresholds are listed in order of Lower Non-Recoverable, Lower Critical, and Lower Non-Critical.

This allows you to set all upper thresholds for a sensor at the same time. The sensor is specified by name and the thresholds are listed in order of Upper Non-Critical, Upper Critical, and Upper Non-Recoverable.

Get information about the specified session(s). You may identify sessions by their id, by their handle number, by their active status, or by using the keyword `all' to specify all sessions.

Session hostname.

Session username.

Session password.

Session privilege level force.

Authentication type force.

Local IPMB address.

Remote target IPMB address.

Remote RMCP port.

Enable output in comma separated format. Affects following commands: user, channel, isol, sunoem, sol, sensor, sdr, sel, session.

Verbosity level.

This command will launch an interactive shell which you can use to send multiple ipmitool commands to a BMC and see the responses. This can be useful instead of running the full ipmitool command each time. Some commands will make use of a Sensor Data Record cache and you will see marked improvement in speed if these commands are able to reuse the same cache in a shell session. LAN sessions will send a periodic keepalive command to keep the IPMI session from timing out.

Retrieve information about the Serial-Over-LAN configuration on the specified channel. If no channel is given, it will display SOL configuration data for the currently used channel.

Enable, disable or show status of SOL payload for the user on the specified channel.

Configure parameters for Serial Over Lan. If no channel is given, it will display SOL configuration data for the currently used channel. Configuration parameter updates are automatically guarded with the updates to the set-in-progress parameter.

Causes ipmitool to enter Serial Over LAN mode, and is only available when using the lanplus interface. An RMCP+ connection is made to the BMC, the terminal is set to raw mode, and user input is sent to the serial console on the remote server. On exit, the the SOL payload mode is deactivated and the terminal is reset to its original settings.

If the instance is given, it will activate using the given instance number. The default is 1.

Special escape sequences are provided to control the SOL session:

~. Terminate connection
~^Z Suspend ipmitool
~^X Suspend ipmitool, but don't restore tty on restart
~B Send break
~~ Send the escape character by typing it twice
~? Print the supported escape sequences

Note that escapes are only recognized immediately after newline.

Deactivates Serial Over LAN mode on the BMC. Exiting Serial Over LAN mode should automatically cause this command to be sent to the BMC, but in the case of an unintentional exit from SOL mode, this command may be necessary to reset the state of the BMC.

If the instance is given, it will deactivate the given instance number. The default is 1.

This command may be used to read SPD (Serial Presence Detect) data using the I2C Master Write-Read IPMI command.

Execute the service processor command line interface commands. Without any command string, an interactive session is started in the service processor command line environ ment. If a command string is specified, the command string is executed on the service processor and the connection is closed.

These commands provide a way to get and set the status of LEDs on a Sun Microsystems server. Use 'sdr list generic' to get a list of devices that are controllable LEDs. The ledtype parameter is optional and not necessary to provide on the command line unless it is required by hardware.

Get status of a particular LED described by a Generic Device Locator record in the SDR. A sensorid of all will get the status of all available LEDS.

Set status of a particular LED described by a Generic Device Locator record in the SDR. A sensorid of all will set the status of all available LEDS to the specified ledmode and ledtype.

This command allows Serial-over-LAN sessions to be established with Tyan IPMIv1.5 SMDC such as the M3289 or M3290. The default command run with no arguments will establish default SOL session back to local IP address. Optional arguments may be supplied in any order.

<ipaddr>

Send receiver IP address to SMDC which it will use to send serial traffic to. By default this detects the local IP address and establishes two-way session. Format of ipaddr is XX.XX.XX.XX

Configure UDP port to receive serial traffic on. By default this is 6230.

Confiure SOL session as read-only or read-write. Sessions are read-write by default.

Displays a summary of userid information, including maximum number of userids, the number of enabled users, and the number of fixed names defined.

Displays a list of user information for all defined userids.

Enables access to the BMC by the given userid.

Set user privilege level on the specified channel. If the channel is not specified, the current channel will be used.

Determine whether a password has been stored as 16 or 20 bytes.

OPEN INTERFACE

The ipmitool open interface utilizes the OpenIPMI kernel device driver. This driver is present in all modern 2.4 and all 2.6 kernels and it should be present in recent Linux distribution kernels. There are also IPMI driver kernel patches for different kernel versions available from the OpenIPMI homepage.

The required kernel modules is different for 2.4 and 2.6 kernels. The following kernel modules must be loaded on a 2.4-based kernel in order for ipmitool to work:

Incoming and outgoing message handler for IPMI interfaces.
An IPMI Keyboard Controler Style (KCS) interface driver for the message handler.
Linux character device interface for the message handler.

The following kernel modules must be loaded on a 2.6-based kernel in order for ipmitool to work:

Incoming and outgoing message handler for IPMI interfaces.
An IPMI system interface driver for the message handler. This module supports various IPMI system interfaces such as KCS, BT, SMIC, and even SMBus in 2.6 kernels.
Linux character device interface for the message handler.

Once the required modules are loaded there will be a dynamic character device entry that must exist at /dev/ipmi0. For systems that use devfs or udev this will appear at /dev/ipmi/0.

To create the device node first determine what dynamic major number it was assigned by the kernel by looking in /proc/devices and checking for the ipmidev entry. Usually if this is the first dynamic device it will be major number 254 and the minor number for the first system interface is 0 so you would create the device entry with:

mknod /dev/ipmi0 c 254 0

ipmitool includes some sample initialization scripts that can perform this task automatically at start-up.

In order to have ipmitool use the OpenIPMI device interface you can specifiy it on the command line:

ipmitool -I open <command>

BMC INTERFACE

The ipmitool bmc interface utilizes the bmc device driver as provided by Solaris 10 and higher. In order to force ipmitool to make use of this interface you can specify it on the command line:

ipmitool -I bmc <command>

The following files are associated with the bmc driver:

/platform/i86pc/kernel/drv/bmc
32-bit ELF kernel module for the bmc driver.
/platform/i86pc/kernel/drv/amd64/bmc
64-bit ELF kernel module for the bmc driver.
/dev/bmc
Character device node used to communicate with the bmc driver.

LIPMI INTERFACE

The ipmitool lipmi interface uses the Solaris 9 IPMI kernel device driver. It has been superceeded by the bmc interface on Solaris 10. You can tell ipmitool to use this interface by specifying it on the command line.

ipmitool -I lipmi <expression>

LAN INTERFACE

The ipmitool lan interface communicates with the BMC over an Ethernet LAN connection using UDP under IPv4. UDP datagrams are formatted to contain IPMI request/response messages with a IPMI session headers and RMCP headers.

IPMI-over-LAN uses version 1 of the Remote Management Control Protocol (RMCP) to support pre-OS and OS-absent management. RMCP is a request-response protocol delivered using UDP datagrams to port 623.

The LAN interface is an authentication multi-session connection; messages delivered to the BMC can (and should) be authenticated with a challenge/response protocol with either straight password/key or MD5 message-digest algorithm. ipmitool will attempt to connect with administrator privilege level as this is required to perform chassis power functions.

You can tell ipmitool to use the lan interface with the -I lan option:

ipmitool -I lan -H <hostname> [-U <username>] [-P <password>] <command>

A hostname must be given on the command line in order to use the lan interface with ipmitool. The password field is optional; if you do not provide a password on the command line, ipmitool will attempt to connect without authentication. If you specify a password it will use MD5 authentication if supported by the BMC and straight password/key otherwise, unless overridden with a command line option.

LANPLUS INTERFACE

Like the lan interface, the lanplus interface communicates with the BMC over an Ethernet LAN connection using UDP under IPv4. The difference is that the lanplus interface uses the RMCP+ protocol as described in the IPMI v2.0 specification. RMCP+ allows for improved authentication and data integrity checks, as well as encryption and the ability to carry multiple types of payloads. Generic Serial Over LAN support requires RMCP+, so the ipmitool sol activate command requires the use of the lanplus interface.

RMCP+ session establishment uses a symmetric challenge-response protocol called RAKP (Remote Authenticated Key-Exchange Protocol) which allows the negotiation of many options. ipmitool does not yet allow the user to specify the value of every option, defaulting to the most obvious settings marked as required in the v2.0 specification. Authentication and integrity HMACS are produced with SHA1, and encryption is performed with AES-CBC-128. Role-level logins are not yet supported.

ipmitool must be linked with the OpenSSL library in order to perform the encryption functions and support the lanplus interface. If the required packages are not found it will not be compiled in and supported.

You can tell ipmitool to use the lanplus interface with the -I lanplus option:

ipmitool -I lanplus -H <hostname> [-U <username>] [-P <password>] <command>

A hostname must be given on the command line in order to use the lan interface with ipmitool. With the exception of the -A and -C options the rest of the command line options are identical to those available for the lan interface.

The -C option allows you specify the authentication, integrity, and encryption algorithms to use for for lanplus session based on the cipher suite ID found in the IPMIv2.0 specification in table 22-19. The default cipher suite is 3 which specifies RAKP-HMAC-SHA1 authentication, HMAC-SHA1-96 integrity, and AES-CBC-128 encryption algorightms.

FREE INTERFACE

The ipmitool free interface utilizes the FreeIPMI libfreeipmi drivers.

You can tell ipmitool to use the FreeIPMI interface with the -I option:

ipmitool -I free <command>

IMB INTERFACE

The ipmitool imb interface supports the Intel IMB (Intel Inter-module Bus) Interface through the /dev/imb device.

You can tell ipmitool to use the IMB interface with the -I option:

ipmitool -I imb <command>
