IPMI-CONFIG(8) System Commands IPMI-CONFIG(8) NAME ipmi-config - configure IPMI values SYNOPSIS ipmi-config [OPTION...] DESCRIPTION ipmi-config is used to get and set configuration parameters in IPMI. In can be used to configured usernames, passwords, networking information, secu- rity, Serial-over-LAN (SOL), Platform Event Filtering (PEF), boot devices, power restoration policy, sensor thresholds, sensor events, and many more configuration options. Some configuration is typically required before most IPMI tools can be used to access a machine remotely. By default, ipmi-config, will let you --checkout or --commit only the core IPMI values necessary for IPMI config- uration. For additional advanced configuration fields related to Chassis configuration (including boot options), Platform Event Filtering (PEF), or Sensors, see the --category option below. For more details on core IPMI configuration, see ipmi-config.conf(5). The majority of configuration operations require ADMIN privilege when using ipmi-config out-of-band. Although connecting via a user with ADMIN privi- leges is not required for out-of-band use, the vast majority of configura- tion options will not be retrieved or set. 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). See GENERAL USE below for a description on basic use of ipmi-config. GENERAL OPTIONS The following options are general options for configuring IPMI communica- tion 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 re- quests 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 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 situa- tions. If specifying an IPv6 address and port, use the format [AD- DRESS]:PORT. -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 as- sumed. The user must have atleast ADMIN 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 pass- word 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 mil- liseconds (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 al- gorithm identifies the algorithm to use for session setup, the in- tegrity algorithm identifies the algorithm to use for session packet signatures, and the confidentiality algorithm identifies the algo- rithm to use for payload encryption. Defaults to cipher suite ID 3 if not specified. The following cipher suite ids are currently sup- ported: 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 ADMIN 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-CONFIG OPTIONS The following options are used to read, write, and find differences in con- figuration values. -g CATEGORY, --category=CATEGORY Specify the category or categories of configuration data to config- ure. Currently available choices: core, chassis, sensors, pef, dcmi. Multiple categories can be separated by comma. core includes all major IPMI configuration necessary to get IPMI to function on a system, such as configuration for users, passwords, authentication, networking, and serial-over-lan (SOL). chassis includes all chassis relevant configuration including boot options, front panel buttons, and power behavior. dcmi includes specialized functions provided by the Data Center Management Interface (DCMI). Defaults to core if not specified. -o, --checkout Fetch configuration information. -c, --commit Update configuration information from a config file or key pairs. -d, --diff Show differences between stored information and a config file or key pairs. -n FILENAME, --filename=FILENAME Specify a config file for checkout/commit/diff. If specified with checkout, cannot use with multiple hosts or with --always-prefix. -e "KEY=VALUE", --key-pair="KEY=VALUE" Specify KEY=VALUE pairs for checkout/commit/diff. Specify KEY by SectionName:FieldName. This option can be used multiple times. On commit, any KEY=VALUE pairs will overwrite any pairs specified in a file with --filename. -S SECTION, --section=SECTION Specify a SECTION for checkout. This option can be used multiple times. The SECTION you are specifying must be within the category or categories specified with --category. -L, --listsections List available sections for checkout with respect to the category or categories under --category. Some sections in the list may not be checked out by default and may require verbosity to be increased. -v, --verbose Output verbose information. When used with --checkout, additional uncommon sections and/or fields will be shown. In the core category, this includes checking out Serial Configuration parameters, Vlan pa- rameters, IPv4 Header parameters, RMCP port, all IPv6 configurable addresses (if > 1 is supported), and sections for each channel on a system (if multiple channels exist). In the pef category, this in- cludes checkout out sections for each channel on a system (if multi- ple channels exist). -vv Output very verbose information. Output additional detailed informa- tion about what fields can and cannot be checked out, and sometimes the reason why. Sometimes output fields that are identified as un- supported on the motherboard. --lan-channel-number=NUMBER Use an specific channel number for LAN configuration. Particularly useful if motherboard contains multiple LAN channels and a user wishes to use a specific one. --serial-channel-number=NUMBER Use an specific channel number for serial configuration. Particu- larly useful if motherboard contains multiple serial channels and a user wishes to use a specific one. --sol-channel-number=NUMBER Use an specific channel number for SOL configuration. Particularly useful if motherboard contains multiple SOL channels and a user wishes to use a specific one. 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. --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 up- dated on a system. --quiet-cache Do not output information about cache creation/deletion. May be use- ful 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. HOSTRANGED OPTIONS 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 un- til 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 identi- cal 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) algo- rithm is used for parallel IPMI communication so that slower nodes or timed out nodes will not impede parallel communication. The maxi- mum 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 at- tempts 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 communi- cating in-band. This option is primarily useful for scripting pur- poses. Option will be ignored if specified with the -C option. GENERAL USE Most users of will want to: A) Run with --checkout to get a copy of the current configuration and store it in a file. The standard output can be redirected to a file or a file can be specified with the --filename option. B) Edit the configuration file with an editor. C) Commit the configuration back using the --commit option and specifying the configuration file with the --filename option. The configuration can be committed to multiple hosts in parallel via the hostrange support. Although not typically necessarily, some motherboards do not store configu- ration values in non-volatile memory. Therefore, after system reboots, some configuration values may have changed. The user may wish to run configura- tion tools on each boot to ensure configuration values remain. Comments will be listed on occasion in checked out files with information on how to configure fields. The ipmi-config.conf(5) manpage also provides additional information on the meaning of different fields. For users with large clusters or sets of nodes, you may wish to use the same configuration file for all nodes. The one problem with this is that the IP address and MAC address will be different on each node in your clus- ter and thus can't be configured through the same config file. The IP ad- dress and MAC address in your config file may be overwritten on the command line using --key-pair option. The following example could be used in a script to configure each node in a cluster with the same BMC config file. The script only needs to determine the correct IP address and MAC address to use. # ipmi-config --commit -k Lan_Conf:Ip_Address=$MY_IP -k Lan_Conf:Mac_Ad- dress=$MY_MAC --filename=my_bmc.conf CORE SPECIAL CASE CONFIGURATION INFORMATION The UserN:Password fields (where N is a number) cannot be checked out on some systems, therefore the checked out value will always be blank. The UserN:Enable_User field (where N is a number) cannot be checked out on older IPMI systems, therefore the checked out value will sometime be blank. The UserN:Lan_Session_Limit and UserN:Serial_Session_Limit fields (where N is a number) cannot be checked out on some systems, therefore the checked out value will always be blank. If not specified in later commits of con- figurations, the field may be reset to 0 due to a requirement that other fields (configured along with the session limit) will require an input value for the session limit. Under most conditions, it is not necessary to set this field and most users may choose to ignore it. This field is con- sidered optional by IPMI standards, and may result in errors when attempt- ing to configure it to a non-zero value. If errors to occur, setting the value back to 0 should resolve problems. The fields Lan_Conf:IP_Address and Lan_Conf:MAC_Address cannot be committed in parallel via hostrange support. Each machine must be configured with a unique IP Address and MAC Address tuple, therefore we disallow this config- uration in ipmi-config. On some motherboards, Lan_Conf:MAC_Address may be read only and the MAC ad- dress is automatically configured. On some motherboards, Lan_Conf:MAC_Address may be read only and the MAC ad- dress is configured via an OEM command. See ipmi-oem(8) to see if OEM con- figuration for your motherboard is supported. On some motherboards, a number of user configuration fields cannot be read or configured until after a non-null username or non-null password is con- figured. In some of these cases, an appropriate output in the config file will indicate this situation. However, not all motherboard corner cases may be detected. Users may wish to play around with the ordering of fields to work around these problems. On some motherboards, OEM Authentication in Lan_Conf_Auth cannot be en- abled. However, the default motherboard settings have these fields enabled. Users are advised to disable all OEM Authentication in this section. On some motherboards, multiple channels may exist for either LAN or Serial IPMI communication. If multiple channels exist, configuration of both chan- nels can be viewed and ultimately configured by running --checkout under verbose mode. Each section or key name will be suffixed appropriately with the word Channel and the channel number. For example, you might see a Lan_Conf_Channel_1 and Lan_Conf_Channel_3, where you can configure LAN con- figuration on Channels 1 and 3 respectively. On some motherboards, configuration changes will not be "absorbed" by the system until the motherboard is hard-reset. This can be accomplished by physically powering off and on the system (e.g. button push), or it can be accomplished through a cold-reset. A cold-reset can be executed via bmc-de- vice. CHASSIS SPECIAL CASE CONFIGURATION INFORMATION The Chassis_Front_Panel_Buttons:Enable_Standby_Button_For_Entering_Standby, Chassis_Front_Panel_Buttons:Enable_Diagnostic_Interrupt_Button Chas- sis_Front_Panel_Buttons:Enable_Reset_Button, and Chassis_Front_Panel_But- tons:Enable_Power_Off_Button_For_Power_Off_Only fields may not be able to be checked out on some IPMI systems, therefore the checked out value may be blank. Some of these fields may be disableable, while some are not. The Chassis_Power_Conf:Power_Control_Interval field cannot be checked out. Therefore the checked out value will always be blank. PEF SPECIAL CASE CONFIGURATION INFORMATION On some motherboards, multiple channels may exist for LAN IPMI communica- tion. If multiple channels exist, configuration of both channels can be viewed and ultimately configured by running --checkout under verbose mode. Each section name will be suffixed appropriately with the word Channel and the channel number. For example, you might see a Community_String_Channel_1 and Community_String_Channel_3, where you can configure the Community String on Channels 1 and 3 respectively. The following are the options suitable for input for Sensor_Type in PEF configuration. Sensor_Type Options Reserved, Temperature, Voltage, Current, Fan, Physical_Security, Platform_Security_Violation_Attempt, Processor, Power_Supply, Power_Unit, Cooling_Device, Other_Units_Based_Sensor, Memory, Drive_Slot, Post_Memory_Resize, System_Firmware_Progress, Event_Log- ging_Disabled, Watchdog1, System_Event, Critical_Interrupt, But- ton_Switch, Module_Board, Microcontroller_Coprocessor, Add_In_Card, Chassis, Chip_Set, Other_FRU, Cable_Interconnect, Terminator, Sys- tem_Boot_Initiated, Boot_Error, OS_Boot, OS_Critical_Stop, Slot_Con- nector, System_ACPI_Power_State, Watchdog2, Platform_Alert, En- tity_Presence, Monitor_Asic_IC, Lan, Management_Subsystem_Health, Battery, Session_Audit, Version_Change, FRU_State, and Any SENSORS SPECIAL CASE CONFIGURATION INFORMATION Since many configurable fields involve decimal numbers, precision/floating point inaccuracies may occur when configuring new thresholds. The inaccura- cies may not be apparent immediately. It is recommend users verify their changes after configuring new thresholds. HOSTRANGED SUPPORT Multiple hosts can be input either as an explicit comma separated lists of hosts or a range of hostnames in the general form: prefix[n-m,l-k,...], where n < m and l < k, etc. The later form should not be confused with reg- ular 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 pre- fixNN naming convention and specification of ranges should not be consid- ered 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 en- close 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 ad- justed 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 exam- ple, output from multiple nodes may be mixed together. The -B and -C op- tions can be used to change this default. In-band IPMI Communication will be used when the host "localhost" is speci- fied. This allows the user to add the localhost into the hostranged output. GENERAL TROUBLESHOOTING Most often, IPMI problems are due to configuration problems. IPMI over LAN problems involve a misconfiguration of the remote machine's BMC. Double check to make sure the following are configured properly in the remote machine's BMC: IP address, MAC address, subnet mask, username, user enablement, user privilege, password, LAN privilege, LAN enablement, and allowed authentication type(s). For IPMI 2.0 connections, double check to make sure the cipher suite privilege(s) and K_g key are configured prop- erly. The ipmi-config(8) tool can be used to check and/or change these con- figuration 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 addi- tional 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 con- figured 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 pos- sible the maximum privilege level allowed for a user is not configured properly on the remote BMC. "authentication type unavailable for attempted privilege level" - The au- thentication 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 authenti- cation types you can authenticate with are not correctly configured on the remote BMC. "cipher suite id unavailable" - The cipher suite id you wish to authenti- cate with is not available on the remote BMC. Please try again with an al- ternate 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 po- tential 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 time- out. 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 com- mand line. "driver timeout" - The inband driver has timed out communicating to the lo- cal BMC or service processor. The BMC or service processor may be busy or (worst case) possibly non-functioning. WORKAROUNDS With so many different vendors implementing their own IPMI solutions, dif- ferent vendors may implement their IPMI protocols incorrectly. The follow- ing describes a number of workarounds currently available to handle discov- ered 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 prob- lems. 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 sys- tems that report invalid base addresses. Those hitting this issue may see "device not supported" or "could not find inband device" errors. Issue ob- served on HP ProLiant DL145 G1. spinpoll - This workaround flag will inform some inband drivers (most no- tably 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 capabil- ities, authentication capabilities, and K_g support and allow IPMI authen- tication to succeed. It works around multiple issues in which the remote system does not properly report username capabilities, authentication capa- bilities, or K_g status. Those hitting this issue may see "username in- valid", "authentication type unavailable for attempted privilege level", or "k_g invalid" errors. Issue observed on Asus P5M2/P5MT-R/RS162-E4/RX4, In- tel 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. How- ever, it is unlikely to be an issue in most situations. Those hitting this issue may see "connection timeout", "session timeout", or "password verifi- cation timeout" errors. On IPMI 1.5 connections, the "noauthcodecheck" workaround may also needed too. Issue observed on Supermicro X9SCM-iiF, Su- permicro 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 auth- codes 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 se- quence 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. How- ever, 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 au- thentication 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 Man- agement 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 au- thentication 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 ob- served 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", "bad rmcpplus status code", or "privi- lege level cannot be obtained for this user" 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, Quanta QSSC-S4R/Appro GB812X-CN, Dell C5220, and the OpenIPMI software BMC. This workaround is automatically triggered with the "sun20" workaround. integritycheckvalue - This workaround flag will work around an invalid in- tegrity check value during an IPMI 2.0 session establishment when using Ci- pher Suite ID 0. The integrity check value should be 0 length, however the remote motherboard responds with a non-empty field. Those hitting this is- sue may see "k_g invalid" errors. Issue observed on Supermicro X8DTG, Su- permicro X8DTU, and Intel S5500WBV/Penguin Relion 700, and Intel S2600JF/Appro 512X. 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 --dri- ver-type=LAN_2_0. Issue observed on a number of HP and Supermicro mother- boards. slowcommit - This workaround will slow down commits to the BMC by sleeping one second between the commit of sections. It works around motherboards that have BMCs that can be overwhelmed by commits. Those hitting this is- sue may see commit errors or commits not being written to the BMC. Issue observed on Supermicro H8QME. veryslowcommit - This workaround will slow down commits to the BMC by sleeping one second between the commit of every key. It works around moth- erboards that have BMCs that can be overwhelmed by commits. Those hitting this issue may see commit errors or commits not being written to the BMC. Issue observed on Quanta S99Q/Dell FS12-TY and Dell PowerEdge T320. solchannelassumelanchannel - This workaround will force ipmi-config to as- sume that the channel used SOL is identical to the channel used for LAN. On some motherboards, the SOL channel is reported incorrectly, leading to in- correct configuration. Most notably, this problem has come up when attempt- ing to configure multiple channels. Issue observed on Intel S5500WBV/Pen- guin Relion 700. EXAMPLES # ipmi-config --checkout Output all core configuration information to the console. # ipmi-config --checkout --category=pef Output all pef configuration information to the console. # ipmi-config --checkout --category=pef,chassis Output all pef and chassis configuration information to the console. # ipmi-config --checkout --filename=bmc-data1.conf Store all core configuration information in bmc-data1.conf. # ipmi-config --diff --filename=bmc-data2.conf Show all difference between the current configuration and the bmc- data2.conf file. # ipmi-config --diff --key-pair="lan_conf_misc:gratuitous_arp_interval=8" Show difference with the current configuration and the 'lan_conf_misc:gra- tuitous_arp_interval' of value '8'. # ipmi-config --commit --filename=bmc-data1.conf Commit all configuration values from the bmc-data1.conf file. # ipmi-config --commit --key-pair="lan_conf_misc:gratuitous_arp_interval=4" Commit key 'lan_conf_misc:gratuitous_arp_interval' of value '4'. # ipmi-config --commit --filename=bmc-data-updt.conf --key- pair="lan_conf_misc:gratuitous_arp_interval=4" Commit all configuration values from bmc-data-updt.conf and key 'lan_conf_misc:gratuitous_arp_interval' of value '4'. DIAGNOSTICS Upon successful execution, exit status is 0. On non-fatal error, exit sta- tus is 1. On fatal error, exit status is 2. If multiple hosts are specified for communication, the exit status is 0 if and only if all targets successfully execute. If any non-fatal error oc- curs, exit status is 1. If any fatal error occurs, exit status is 2. KNOWN ISSUES On older operating systems, if you input your username, password, and other potentially security relevant information on the command line, this infor- mation 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. Config- uring 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 authen- ticate again. REPORTING BUGS Report bugs to <freeipmi-users@gnu.org> or <freeipmi-devel@gnu.org>.
