IPMI-SEL(8) System Commands IPMI-SEL(8) NAME ipmi-sel - display SEL entries SYNOPSIS ipmi-sel [OPTION...] DESCRIPTION Ipmi-sel is used to view and manage System Event Log (SEL) entries. SEL records store system event information and may be useful for debugging problems. Ipmi-sel does not inform the user if an event is particularly good or bad, just that the event occurred. Users may wish to use the --out- put-event-state option to output the analyzed state. 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). To perform some advanced SEL management, please see bmc-device(8). 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 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 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 OPERATOR if not specified. --config-file=FILE Specify an alternate configuration file. -W WORKAROUNDS, --workaround-flags=WORKAROUNDS Specify workarounds to vendor compliance issues. Multiple workarounds can be specified separated by commas. A special command line flag of "none", will indicate no workarounds (may be useful for overriding configured defaults). See WORKAROUNDS below for a list of available workarounds. --debug Turn on debugging. -?, --help Output a help list and exit. --usage Output a usage message and exit. -V, --version Output the program version and exit. IPMI-SEL OPTIONS The following options are specific to ipmi-sel. -v Output verbose output. This option will output event direction. Event direction may be useful to differentiate severity between some events. For example, some motherboards may issue an event both when a temperature exceeds a threshold and when it goes back down below it. -vv Output very verbose output. This option will output additional in- formation than verbose output. Most notably it will output addi- tional hex codes to given information on ambiguous SEL entries, such as OEM codes. For example, it will output Generator ID hex codes for sensors without names, event type codes for OEM events, and record types for OEM records. This information may be useful if you are writing a parser outside of ipmi-sel to interpret OEM information. -i, --info Show general information about the SEL. --display=RECORD-IDS-LIST Display SEL records by record id. Accepts space or comma separated lists. --exclude-display=RECORD-IDS-LIST Exclude display of SEL records by record id. Accepts space or comma separated lists. --display-range=START-END Display SEL records from record id START to END. --exclude-display-range=START-END Exclude display of SEL records from record id START to END. --date-range=DATE-DATE Display SEL records with events occurring in the specified date range. Dates may be specified in MM/DD/YYYY, MM-DD-YYYY or the ISO 8601 YYYY-MM-DDTHH:MM:SS format. For the non ISO 8601 formats, the month may be specified as a numeral or its abbreviated string name. The current local system time can be specified with "now". Note that non-timestamped records will not be displayed automatically because they do not possess a timestamp. --exclude-date-range=DATE-DATE Exclude display of SEL records with events occurring in the speci- fied date range. Dates may be specified in MM/DD/YYYY, MM-DD-YYYY or the ISO 8601 YYYY-MM-DDTHH:MM:SS format. For the non ISO 8601 for- mats, the month may be specified as a numeral or its abbreviated string name. The current local system time can be specified with "now". Note that non-timestamped records will be displayed automat- ically because they do not possess a timestamp. -t SENSOR-TYPE-LIST, --sensor-types=SENSOR-TYPE-LIST Specify sensor types to show SEL events for. Multiple types can be separated by commas or spaces. A special command line type of "all", will indicate all types should be shown (may be useful for overrid- ing configured defaults). Users may specify sensor types by string (see --list-sensor-types below) or by number (decimal or hex). -T SENSOR-TYPE-LIST, --exclude-sensor-types=SENSOR-TYPE-LIST Specify sensor types to not show SEL events for. Multiple types can be separated by commas or spaces. A special command line type of "none", will indicate no types should be excluded (may be useful for overriding configured defaults). Users may specify sensor types by string (see --list-sensor-types below) or by number (decimal or hex). -L, --list-sensor-types List sensor types. --tail=count Display approximately the last count SEL records. The display count is calculated by approximating the record ids of the last SEL records. It's correctness depends highly on the SEL implementation by the vendor. --clear Clear SEL. --post-clear Identical to --clear, except the SEL clearing will be performed af- ter SEL event records are displayed. This option is useful for scripting if users intend to log SEL events to another log, then im- mediately clear SEL. Unlike calling --clear in another execution of ipmi-sel, this option will use SEL reservations to notify the user if a SEL change has occurred while displaying and clearing the SEL. This can protect users from a race, where a new SEL event is unknow- ingly generated before clearing the SEL. Note that SEL reservations are optionally implemented by vendors and may not be available on all machines. --delete=RECORD-IDS-LIST Delete records by record id in the SEL. Accepts space or comma sepa- rated lists. --delete-range=START-END Delete record ids from START to END in the SEL. --system-event-only Output only system event records (i.e. don't output OEM records). --oem-event-only Output only OEM event records (i.e. don't output system event records). --output-manufacturer-id For OEM SEL record types, output the manufacturer ID along with event data when available. --output-event-state Output event state in output. This will add an additional output re- porting if an event should be viewed as NOMINAL, WARNING, or CRITI- CAL. The event state is an interpreted value based on the configu- ration file /usr/local/etc/freeipmi/freeipmi_interpret_sel.conf and the event direction. See freeipmi_interpret_sel.conf(5) for more information. --event-state-config-file=FILE Specify an alternate event state configuration file. Option ignored if --output-event-state not specified. --hex-dump Hex-dump SEL entries. --interpret-oem-data Attempt to interpret OEM data, such as event data, sensor readings, or general extra info, etc. If an OEM interpretation is not avail- able, the default output will be generated. Correctness of OEM in- terpretations cannot be guaranteed due to potential changes OEM ven- dors may make in products, firmware, etc. See OEM INTERPRETATION be- low for confirmed supported motherboard interpretations. --output-oem-event-strings Some motherboards support an IPMI OEM extension that returns the string output for a system event. Such string output may be benefi- cial for determining the meaning behind OEM specific events. This option will use the OEM event string to describe all system events in the ipmi-sel output. This option differs from --inter- pret-oem-data option in that all system events will output the ven- dor supplied event string, not just events that are OEM specific. The event string may be very different from the normal FreeIPMI event string output. If an OEM event strings is not available, the default output will be output. This option is confirmed to work for Fujitsu iRMC S1 and iRMC S2 systems. --entity-sensor-names Output sensor names prefixed with their entity id and instance num- ber when appropriate. This may be necessary on some motherboards to help identify what sensors are referencing. For example, a mother- board may have multiple sensors named 'TEMP'. The entity id and in- stance number may help clarify which sensor refers to "Processor 1" vs. "Processor 2". --no-sensor-type-output Do not show sensor type output for each entry. On many systems, the sensor type is redundant to the name of the sensor. This can espe- cially be true if --entity-sensor-names is specified. If the sensor name is sufficient, or if the sensor type is of no interest to the user, this option can be specified to condense output. --comma-separated-output Output fields in comma separated format. --no-header-output Do not output column headers. May be useful in scripting. --non-abbreviated-units Output non-abbreviated units (e.g. 'Amps' instead of 'A'). May aid in disambiguation of units (e.g. 'C' for Celsius or Coulombs). --legacy-output Output in legacy format. Newer options may not be applicable to legacy output. 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. --ignore-sdr-cache Ignore SDR cache related processing. May lead to incomplete or less useful information being output, however it will allow functionality for systems without SDRs or when the correct SDR cannot be loaded. TIME OPTIONS By IPMI definition, all IPMI times and timestamps are stored in localtime. However, in many situations, the timestamps will not be stored in local- time. 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. 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. 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. "internal IPMI error" - An IPMI error has occurred that FreeIPMI does not know how to handle. Please e-mail <freeipmi-users@gnu.org> to report the issue. IPMI-SEL TROUBLESHOOTING Some timestamps in the SEL may report a date of 1-Jan-1970, the epoch for SEL timestamps. This timestamp is not necessarily incorrect. It usually in- dicates a hardware event that occurred before a timestamp in firmware has been initialized. For example, certain hardware components will have their internal clocks reset during a power cycle. However, if the internal clock of the SEL appears to be regularly incor- rect, you may need to set the SEL time. This can be done using bmc-de- vice(8). The following are common SEL related messages. "sel config file parse error" - A parse error was found in the sel event interpretation configuration file. Please see freeipmi_inter- pret_sel.conf(5). WORKAROUNDS With so many different vendors implementing their own IPMI solutions, 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. assumemaxsdrrecordcount - This workaround will inform SDR reading to stop reading after a known maximum number of SDR records have been read. This will work around systems that have miss-implemented SDR reading functions. Those hitting this issue may see "SDR record count invalid" errors. Issue observed on unspecified Inspur motherboard. assumesystemevent - This workaround option will assume invalid SEL record types are system event records. Records may be formatted correctly but re- port invalid record types. Those hitting this issue may see "Unknown SEL Record Type" errors. Output may be unknown, pray for the best. This option is confirmed to work around compliances issues on HP DL 380 G5 mother- boards. 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. OEM INTERPRETATION The following motherboards are confirmed to have atleast some support by the --interpret-oem-data option. While highly probable the OEM data inter- pretations would work across other motherboards by the same manufacturer, there are no guarantees. Some of the motherboards below may be rebranded by vendors/distributors.

EXAMPLES # ipmi-sel Show all SEL records on the local machine. # ipmi-sel -h ahost -u myusername -p mypassword Show all SEL records of a remote machine using IPMI over LAN. # ipmi-sel -h mycluster[0-127] -u myusername -p mypassword Show all SEL records across a cluster using IPMI over LAN. # ipmi-sel --delete=44,82 Delete SEL records 44 and 82 on the local machine. # ipmi-sel --delete-all Delete all SEL entries on the local machine. # ipmi-sel --delete-range=12-42 Delete SEL entries in the range 12 to 42 on the local machine. DIAGNOSTICS 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. 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>.
