Perform advanced bmc commands
bmc-device [OPTION...]
bmc-device supports a variety of IPMI commands to perform advanced BMC functions. This tool is primarily used for development debugging, BMC error recory, retrieving detailed technical information, and other advanced purposes. Most IPMI users will not need to use this tool. Some of the bmc-device commands are not supported on all motherboards.
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).
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\FR
Specify the in-band driver target channel number to send IPMI requests to.
--target-slave-address=SLAVE-ADDRESS\FR
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

-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

--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.
The following options are specific to bmc-device.
--cold-reset

--warm-reset
Perform a warm reset.
--get-self-test-results
Output BMC self test results.
--get-acpi-power-state
Get ACPI system and device power state.
--set-acpi-power-state
Set ACPI power state. Must be specified to use the --set-acpi-system-power-state, and --set-acpi-device-power-state options listed below.
--set-acpi-system-power-state=SYSTEM_POWER_STATE
Set ACPI system power state. Allowed values: S0_G0, S1, S2, S3, S4, S5_G2, S4_S5, G3, SLEEPING, G1_SLEEPING, OVERRIDE, LEGACY_ON, LEGACY_OFF, UNKNOWN. Used with the --set-acpi-power-state option.
--set-acpi-device-power-state=DEVICE_POWER_STATE
Set ACPI device power state. Allowed values: D0, D1, D2, D3, UNKNOWN. Used with the --set-acpi-power-state option.

Get IP, UDP, and RMCP statistics.
--clear-lan-statistics
Clear IP, UDP, and RMCP statistics.
--rearm-sensor="<record_id> [<assertion_bitmask> <deassertion_bitmask>]"
Re-arm a sensor. Re-arming a sensor informs the internal device to reset and re-evaluate a sensor reading and events. Most sensors are automatically re-armed, however a rare few do require manual re-arming. This option may also be useful to reset a sensor reading or event that may be stuck due to an internal hardware or firmware error. If the assertion_bitmask and deassertion_bitmask are specified, only the specific events will be re-armed. If not specified, all possible events will be re-armed. This command requires the loading of the SDR.
--get-sdr-repository-time
Get SDR repository time.
--set-sdr-repository-time=TIME
Set SDR repository time. Input format = "MM/DD/YYYY - HH:MM:SS". Note that hours are input in 24 hour form. Alternatively, the local system time can be specified with "now".
--get-sel-time
Get SEL time.
--set-sel-time=TIME
Set SEL time. Input format = "MM/DD/YYYY - HH:MM:SS". Note that hours are input in 24 hour form. Alternatively, the local system time can be specified with "now".
--get-sel-time-utc-offset
Get SEL time UTC offset.
--set-sel-time-utc-offset=MINUTES
Set SEL time UTC offset. Input is in minutes difference from UTC time, ranging from -1440 to 1440 minutes. A special case value of "none" can be specified so no UTC offset is specified.
--platform-event="[generator_id] <event_message_format_version> <sensor_type> <sensor_number> <event_type> <event_direction> <event_data1> <event_data2> <event_data3>"
Instruct the BMC to process the specified event data. Typically, this data will be logged to the System Event Log (SEL), but depending on implementation it may be processed by other subsystems such as Platform Event Filtering (PEF). The keywords assertion or deassertion may be used for event_direction, or the numerical values may be used instead. The event_message_format_version is 0x03 for IPMI 1.0 and 0x04 for IPMI 1.5. The generator_id above is optional, however it is required if generating the event via a system interface (i.e. inband). If generating the event via a system interface, the system management software generator id range is 0x41 to 6Fh.
--set-sensor-reading-and-event-status="<sensor_number> <sensor_reading> <sensor_reading_operation> <assertion_bitmask> <assertion_bitmask_operation> <deassertion_bitmask> <deassertion_bitmask_operation> <event_data1> <event_data2> <event_data3> <event_data_operation>"
Instruct the BMC to set a sensor reading and/or event status. How the various fields are written depends on a set of operation instructions specified. The sensor_reading can be written or not changed with the respective operation write and nochange. For the assertion_bitmask and deassertion_bitmask, the 0 bits of the bitmask can clear the bits of the status, the 1 bits of the bitmask can set the bits of the status, the entire bitmask can be written as the status, or the status cannot be changed respecitvely with the respective operations clear0bits, set1bits, write, and nochange. The event_data1 byte can be written fully, written without the event offset (bits 3:0), or not be changed via the write, nooffsetwrite, or nochange operations.
--get-mca-auxiliary-log-status
Get machine check architecture (MCA) auxiliary log status information.
--get-ssif-interface-capabilities
Get SSIF interface capabilities.
--get-kcs-interface-capabilities
Get KCS interface capabilities.
--get-bt-interface-capabilities
Get BT interface capabilities.
--get-bmc-global-enables
Get BMC Global Enables.
--set-system-firmware-version=STRING
Set System Firmware Version.
--set-system-name=STRING
Set System Name.
--set-primary-operating-system-name=STRING
Set Primary Operating System Name.
--set-operating-system-name=STRING
Set Operating System Name.
--set-present-os-version-number=STRING
Set Present OS Version Number.
--set-bmc-url=STRING
Set BMC URL.
--set-base-os-hypervisor-url=STRING
Set Base OS/Hypervisor URL.
--verbose
Increase verbosity in output.
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.
By IPMI definition, all IPMI times and timestamps are stored in localtime. However, in many situations, the timestamps will not be stored in localtime. Whether or not a system truly stored the timestamps in localtime varies on many factors, such as the vendor, BIOS, and operating system. The following options will allow the user to adjust the interpretation of the stored timestamps and how they should be output.
--utc-to-localtime
Assume all times are reported in UTC time and convert the time to localtime before being output.
--localtime-to-utc
Convert all localtime timestamps to UTC before being output.
--utc-offset=SECONDS
Specify a specific UTC offset in seconds to be added to timestamps. Value can range from -86400 to 86400 seconds. Defaults to 0.
The following options manipulate hostranged output. See HOSTRANGED SUPPORT below for additional information on hostranges.
-B, --buffer-output
Buffer hostranged output. For each node, buffer standard output until the node has completed its IPMI operation. When specifying this option, data may appear to output slower to the user since the the entire IPMI operation must complete before any data can be output. See HOSTRANGED SUPPORT below for additional information.
-C, --consolidate-output
Consolidate hostranged output. The complete standard output from every node specified will be consolidated so that nodes with identical output are not output twice. A header will list those nodes with the consolidated output. When this option is specified, no output can be seen until the IPMI operations to all nodes has completed. If the user breaks out of the program early, all currently consolidated output will be dumped. See HOSTRANGED SUPPORT below for additional information.
-F NUM, --fanout=NUM
Specify multiple host fanout. A "sliding window" (or fanout) algorithm is used for parallel IPMI communication so that slower nodes or timed out nodes will not impede parallel communication. The maximum number of threads available at the same time is limited by the fanout. The default is 64.
-E, --eliminate
Eliminate hosts determined as undetected by ipmidetect. This attempts to remove the common issue of hostranged execution timing out due to several nodes being removed from service in a large cluster. The ipmidetectd daemon must be running on the node executing the command.
--always-prefix
Always prefix output, even if only one host is specified or communicating in-band. This option is primarily useful for scripting purposes. Option will be ignored if specified with the -C option.
Multiple hosts can be input either as an explicit comma separated lists of hosts or a range of hostnames in the general form: prefix[n-m,l-k,...], where n < m and l < k, etc. The later form should not be confused with regular expression character classes (also denoted by []). For example, foo[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.
When multiple hosts are specified by the user, a thread will be executed for each host in parallel up to the configured fanout (which can be adjusted via the -F option). This will allow communication to large numbers of nodes far more quickly than if done in serial.
By default, standard output from each node specified will be output with the hostname prepended to each line. Although this output is readable in many situations, it may be difficult to read in other situations. For example, output from multiple nodes may be mixed together. The -B and -C options can be used to change this default.
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.
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 <[email protected]> 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.
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 <[email protected]> or <[email protected]>.
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.
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.
# bmc-device --cold-reset
Perform a cold reset.
# bmc-device -h ahost -u myusername -p mypassword --cold-reset
Perform a cold reset of a remote machine using IPMI over LAN.
# bmc-device -h mycluster[0-127] -u myusername -p mypassword --cold-reset
Perform a cold reset across a cluster using IPMI over LAN.
Upon successful execution, exit status is 0. On error, exit status is 1.
If multiple hosts are specified for communication, the exit status is 0 if and only if all targets successfully execute. Otherwise the exit status is 1.
On older operating systems, if you input your username, password, and other potentially security relevant information on the command line, this information may be discovered by other users when using tools like the 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.
