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.  Although output may vary dependent on individual SEL events,
       most entries will display the SEL record id, date  of  event,  time  of
       event, sensor group, sensor name, and the sensor event occurrence.

       Some  timestamps  in  the  SEL  may  report  a date of 1-Jan-1970. This
       timestamp is not necessarily incorrect. It usually indicates 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.

GENERAL OPTIONS

       The   following  options  are  general  options  for  configuring  IPMI
       communication and executing general tool commands.

       -D, --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,
              and SUNBMC.

       --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.

       -h, --hostname=IPMIHOST1,IPMIHOST2,...
              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.

       -u, --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
              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
              Specify the K_g BMC key to  use  when  authenticating  with  the
              remote  host  for  IPMI  2.0.  If  not  specified, a null key is
              assumed. To input the key in hexadecimal form, prefix the string
              with  ’0x’.  E.g.,  the key ’abc’ can be entered with the either
              the string ’abc’ or the string ’0x616263’

       -K, --k-g-prompt
              Prompt for k-g to avoid possibility of  listing  it  in  process
              lists.

       --session-timeout=MILLISECONDS
              Specify  the  session timeout in milliseconds. Defaults to 20000
              milliseconds (20 seconds) if not specified.

       --retransmission-timeout=MILLISECONDS
              Specify  the  packet  retransmission  timeout  in  milliseconds.
              Defaults  to  1000 milliseconds (1 second) if not specified. The
              retransmission  timeout  cannot  be  larger  than  the   session
              timeout.

       -a, --authentication-type=AUTHENTICATION-TYPE
              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
              Specify the IPMI 2.0 cipher suite ID to use. The Cipher Suite ID
              identifies   a   set   of   authentication,    integrity,    and
              confidentiality  algorithms  to  use for IPMI 2.0 communication.
              The authentication algorithm identifies the algorithm to use for
              session  setup, the integrity algorithm identifies the algorithm
              to use for session packet signatures,  and  the  confidentiality
              algorithm   identifies   the   algorithm   to  use  for  payload
              encryption. Defaults to cipher suite ID 3 if not specified.  The
              following cipher suite ids are currently supported:

              0 - Authentication Algorithm = None; Integrity Algorithm = None;
              Confidentiality Algorithm = None

              1 - Authentication Algorithm = HMAC-SHA1; Integrity Algorithm  =
              None; Confidentiality Algorithm = None

              2  - Authentication Algorithm = HMAC-SHA1; Integrity Algorithm =
              HMAC-SHA1-96; Confidentiality Algorithm = None

              3 - Authentication Algorithm = HMAC-SHA1; Integrity Algorithm  =
              HMAC-SHA1-96; Confidentiality Algorithm = AES-CBC-128

              6  -  Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
              None; Confidentiality Algorithm = None

              7 - Authentication Algorithm = HMAC-MD5; Integrity  Algorithm  =
              HMAC-MD5-128; Confidentiality Algorithm = None

              8  -  Authentication Algorithm = HMAC-MD5; Integrity Algorithm =
              HMAC-MD5-128; Confidentiality Algorithm = AES-CBC-128

              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

       -l, --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, --workaround-flags=WORKAROUNDS
              Specify  workarounds  to  vendor  compliance  issues.   Multiple
              workarounds   can   be   specified   separated  by  commas.  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.

       -i, --info
              Show general information about the SEL.

       -c, --delete-all
              Delete all SEL records.

       -d REC-LIST, --delete=REC-LIST
              Delete records by record id in the SEL. Accepts space  or  comma
              separated lists.

       --delete-range=START-END
              Delete record ids from START to END in the SEL.

       -x [FILE], --hex-dump[=FILE]
              Hex-dump SEL entries optionally into a FILE.

       --assume-system-event-records
              Some  motherboards have invalid SEL record types listed, leading
              to errors such as ’Unknown SEL Record  Type’.  The  records  may
              actually be formatted correctly. Use this option to assume these
              invalid record types are system event records and pray  for  the
              best.

SDR CACHE OPTIONS

       This tool requires access to the sensor data repository (SDR) cache for
       general operation. By default, SDR data will be downloaded  and  cached
       on the local machine. The following options apply to the SDR cache.

       -f, --flush-cache
              Flush  a  cached  version  of  the  sensor data repository (SDR)
              cache. The SDR is typically cached for faster subsequent access.
              However,  it  may need to be flushed and re-generated if the SDR
              has been updated on a system.

       -Q, --quiet-cache
              Do not output information about cache creation/deletion.

       --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.

       --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.

       --ignore-sdr-cache
              Ignore SDR cache related processing. May lead to  incomplete  or
              less  useful  information  being  output,  however it will allow
              functionality for those systems without SDRs.

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
              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, --fanout
              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.

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  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.

       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.

GENERAL TROUBLESHOOTING

       Most often, 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  bmc-
       config(8)  tool  can be used to check and/or change these configuration
       settings.

       The following are common issues for given error messages:

       "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 IPMI over LAN continually times out, you may wish  to  increase  the
       retransmission  timeout.  Some remote BMCs are considerably slower than
       others.

       Please see WORKAROUNDS below to also if there are any  vendor  specific
       bugs that have been discovered and worked around.

WORKAROUNDS

       With  so  many different vendors implementing their own IPMI solutions,
       different vendors may implement their IPMI protocols  incorrectly.  The
       following  lists  the  handful  of compliance issues discovered and the
       workarounds currently supported.

       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.

       Intel  SR870BN4:  BMCs  would  not  respond to retransmissions of a Get
       Session Challenge Request if a previous Get Session Challenge  response
       was  lost.  Resolved  by  sending  retransmitted  Get Session Challenge
       requests from a different source port. Automatically handled.

       Tyan S2882 with m3289 BMC: After the IPMI session is brought up, packet
       responses  return  empty  session  IDs  to the client. This will likely
       cause "session timeout" errors to occur. In order to work  around  this
       issue, the "idzero" workaround must be specified. The option will allow
       empty session IDs to be accepted by the client.

       Dell  PowerEdge  2850,SC1425:  When   Per-Message   Authentication   is
       disabled,  packet  responses contain non-null authentication data (when
       it should in fact be null). This will likely  cause  "session  timeout"
       errors   to   occur.   In   order   to  work  around  this  issue,  the
       "unexpectedauth" workaround must be specified. The  option  will  allow
       unexpected  non-null  authcodes  to  be  checked  as  though  they were
       expected. This compliance  bug  is  confirmed  to  be  fixed  on  newer
       firmware.

       IBM  eServer  325:  The  remote  BMC  will  advertise  that Per Message
       Authentication is disabled, but actually require it for  the  protocol.
       This  will  likely cause "session timeout" errors to occur. In order to
       work around this issue, the "forcepermsg" workaround must be specified.
       The  option  will force Per Message Authentication to be used no matter
       what is advertised by the remote BMC.

       Supermicro  H8QME  with  SIMSO  daughter  card:  The  remote  BMC  will
       advertise  that  Per  Message  Authentication is disabled, but actually
       require it for the protocol. Automatically handled.

       Asus P5M2/P5MT-R/RS162-E4/RX4: The motherboard does not properly report
       username  capabilities  and/or  K_g  status.  This  will  likely  cause
       "username invalid" or "k_g invalid" errors to occur. In order  to  work
       around this issue, the "authcap" workaround must be specified.

       Intel SR1520ML/X38ML: The motherboard does not properly report username
       capabilities and/or  K_g  status.  This  will  likely  cause  "username
       invalid" or "k_g invalid" errors to occur. In order to work around this
       issue, the "authcap" workaround must be specified.

       Sun ILOM 1.0/2.0: The session sequence numbers returned  for  IPMI  1.5
       sessions  are  the  wrong  endian on some systems running ILOM 1.0/2.0.
       The incorrect endian depends on the service processor endianness.  This
       will  likely  cause "session timeout" errors to occur. In order to work
       around this issue, the "endianseq" workaround must be specified.

       Sun Fire 2200/4150/4450 with ELOM: The motherboard  does  not  properly
       report username capabilities. This will likely cause "username invalid"
       errors to occur.  In order to work around  this  issue,  the  "authcap"
       workaround must be specified.

       Intel  SE7520AF2  with  Intel  Server  Management  Module (Professional
       Edition): There are a number of Intel  IPMI  2.0  authentication  bugs.
       These  problems  may  cause  "username invalid", "password invalid", or
       "k_g invalid" errors to occur. They can be worked around by  specifying
       the "intel20" workaround. The workarounds include padding of usernames,
       automatic acceptance of a RAKP 4 response integrity  check  when  using
       the  integrity  algorithm  MD5-128,  and  password  truncation  if  the
       authentication algorithm is HMAC-MD5-128.

       Supermicro H8QME with SIMSO daughter card: There are several Supermicro
       IPMI  2.0  bugs  on early firmware revisions which can be worked around
       using the "supermicro20" workaround. These problems may cause "password
       invalid"  errors  to  occur.  These compliance bugs are confirmed to be
       fixed on newer firmware.

       Sun Fire 4100/4200/4500 with ILOM: There are several Sun IPMI 2.0 bugs.
       These  problems  may  cause "password invalid" or "bmc error" errors to
       occur. They can be worked around by specifying the "sun20"  workaround.
       The workarounds include handling invalid lengthed hash keys, improperly
       hashed keys, and invalid cipher suite records.

       Inventec 5441, Supermicro X8DTH: 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.
       This  may cause "password invalid" or "bad rmcpplus status code" errors
       to occur. It can be worked  around  by  specifying  the  "opensesspriv"
       workaround.

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.

KNOWN ISSUES

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

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