 NAME    [Toc]    [Back]
      netfmt - format tracing and logging binary files

 SYNOPSIS    [Toc]    [Back]
      /usr/sbin/netfmt [-k] -s [-t records] [[-f] file_name]

      /usr/sbin/netfmt [-k] -p [-c config_file]

      /usr/sbin/netfmt [-c config_file] [-F] [-t records] [-v] [-l] [-n]
           [-N | [-1 [-L] [-T]]] [[-f] file_name]

      /usr/sbin/netfmt -k [-c config_file] [-F] [-t records] [-v]
           [[-f] file_name]

 DESCRIPTION    [Toc]    [Back]
      netfmt is used to format binary trace and log data gathered from the
      network tracing and logging facility (see nettl(1M)) and the kernel
      logging facility (see kl(1M)).  The binary trace and log information
      can be read from a file or from standard input (if standard input is a
      tty device, an informative message is given and netfmt quits).
      Formatted data is written to standard output.

      Formatting options are specified in an optional filter configuration
      file.  Message inclusion and format can be controlled by the filter
      configuration file.  If no configuration commands are specified, all
      messages are fully formatted.

      There are two types of global formatting done by netfmt.  The first
      one is global filtering for NetTL's trace/log packets and the other is
      for KL's log packets. A description of the filter configuration file
      follows the option descriptions.

    Options    [Toc]    [Back]
      netfmt recognizes the following command-line options and arguments:

           -k             This option tells netfmt that the input file is a
                          KL log file.  This option should be specified if
                          the user needs to log messages got from KL
                          subsystems.  This option cannot be specified
                          anywhere except as the first option in the command
                          line.

           -s             Display a summary of the input file.  The summary
                          includes the total number of messages, the
                          starting and ending timestamps, the types of
                          messages, and information about the system that
                          the data was collected on.  The contents of the
                          input file are not formatted; only a summary is
                          reported.





 Hewlett-Packard Company            - 1 -   HP-UX 11i Version 2: August 2003






 netfmt(1M)                                                       netfmt(1M)




           -t records     Specifies the number of records from the tail end
                          of the input file to format.  This allows the user
                          to bypass extraneous information at the beginning
                          of the file, and get to the most recent
                          information quickly.  The maximum number of
                          records that can be specified is 1000.  If
                          omitted, all records are formatted.  The -t option
                          is not allowed when the input file is a FIFO
                          (pipe).

           -f file_name   Specifies the input file containing the binary log
                          or trace data.  file_name may not be the name of a
                          tty device.  Other options may impose additional
                          restrictions on the type of the input file
                          allowed.  If omitted, data is read from standard
                          input.

           -p             Parse input: this switch allows the user to
                          perform a syntax check on the config_file
                          specified by the -c parameter.  All other
                          parameters are ignored.  If the syntax is correct,
                          netfmt terminates with no output or warnings.

           -c config_file Specifies the file containing formatter filter
                          configuration commands.  Syntax for the commands
                          is given below.  When -c is omitted the file
                          $HOME/.netfmtrc is read for both logging and
                          tracing filter configuration commands if it
                          exists.

           -F             Follow the input file.  Instead of closing the
                          input file when end of file is encountered, netfmt
                          keeps it open and continues to read from it as new
                          data arrives.  This is especially useful for
                          watching events occur in real time while
                          troubleshooting a problem.  Another use would be
                          for recording events to a console or hard-copy
                          device for auditing.  (Note that console logging
                          is controlled by the configuration files
                          /etc/nettlgen.conf and /var/adm/conslog.opts; see
                          nettlgen.conf(4).) The -F option is not allowed
                          when the input file is redirected.

      The following options are not supported by all subsystems.  If a
      subsystem does not support an option, that option is ignored during
      formatting of data from that subsystem.  Consult the product
      documentation of the subsystem for information regarding the support
      of these options.

           -v             Enables output of verbose information.  This
                          includes additional cause and action text with



 Hewlett-Packard Company            - 2 -   HP-UX 11i Version 2: August 2003






 netfmt(1M)                                                       netfmt(1M)




                          formatted output.  This information describes the
                          possible cause of the message and any actions that
                          may be required by the subsystem.

                          After the contents of the input file have been
                          formatted a summary of the file is displayed.
                          When this option is used with the -t option, only
                          a summary of the last records is reported.  No
                          summary is produced when this option is used in
                          conjunction with the -F option or if formatting is
                          interrupted.

           -l             (ell) Turn off inverse video highlighting of
                          certain traced fields.  Use this flag when sending
                          formatted trace data to a line printer.  By
                          default, certain fields in the trace file are
                          highlighted in inverse video when viewing the
                          formatted trace format at a terminal that supports
                          highlighting.

           -n             Shows port numbers and network addresses(such as
                          IP and x121) as numbers (normally, netfmt
                          interprets numbers and attempts to display them
                          symbolically).

           -N             Enables ``nice'' formatting where
                          Ethernet/IEEE802.3, SLIP, IP, ICMP, IGMP, TCP,
                          UDP, and RPC packets are displayed symbolically.
                          All remaining user data is formatted in
                          hexadecimal and ASCII.

           -1             (one) Attempts to tersely format each traced
                          packet on a single line.  If -L and/or -T options
                          are used, the output lines will be more than 80
                          characters long.

           -T             Places a time stamp on terse tracing output.  Used
                          with the -1 (minus one) option.

           -L             Prefixes local link address information to terse
                          tracing output.  Used with the -1 (minus one)
                          option.

    Filter Configuration File    [Toc]    [Back]
      Note: Filter configuration file syntax converges the syntax used with
      the obsolete nettrfmt network trace formatter and netlogfmt network
      log formatter commands with new netfmt syntax for controlling
      formatter options.  The first section below describes the general use
      and syntax of the filter configuration file.  Specific options for
      subsystem Naming and Filtering are listed in the Subsystem Filtering
      section below.



 Hewlett-Packard Company            - 3 -   HP-UX 11i Version 2: August 2003






 netfmt(1M)                                                       netfmt(1M)




      The filter configuration file allows specification of two types of
      information:

           +  Specify options in order to control how the input data is to
              be formatted.  These options determine what the output looks
              like and allow a user to select the best format to suit their
              needs.

           +  Specify filters in order to precisely tailor what input data
              is to be discarded and what is to be formatted.  Global
              filters control all subsystems; subsystem filters pertain only
              to specific subsystems.  There are two types of Global filters
              that netfmt supports. The global filtering can start with
              either the word formatter, which means it is global to all the
              NetTL's subsystems and the second type starts with the word
              kl_formatter, which is used to filter KL's subsystems.

      A filter is compared against values in the input data.  If the data
      matches a filter, the data is formatted; otherwise, the input data is
      discarded.  A filter can also specify NOT by using ! before the filter
      value in the configuration file.  If the input data matches a NOT
      filter, it is discarded.  A filter can also be a ``wild-card''
      (matching any value) by specifying an asterisk * before the filter
      value in the configuration file.  ``Wild card'' filters pass all
      values of the input data.  Specifying !* as the filter means NOT ALL.

    Filter Configuration File Syntax    [Toc]    [Back]
           +  The formatter ignores white space, such as spaces or tabs.
              However, newlines (end of line characters) are important, as
              they terminate comments and filter specifications.

           +  The formatter is not case sensitive.  For example error and
              ERROR are treated as equivalent.

           +  To place comments in the file, begin each comment line with a
              # character.  The formatter ignores all remaining characters
              on that line.  There are no inline comments allowed.

           +  An exclamation point (!) in front of an argument indicates
              NOT.  This operator is not supported for timestamp, log
              instance, and ID filtering.

           +  The asterisk (*), when used as an argument, indicates ALL.
              Since the default for all formatting options is ALL, it is
              unnecessary to use the asterisk alone.  It can be used along
              with the exclamation point, (!*) to indicate NOT ALL.  This
              operator is not available for timestamp, log instance, and ID
              filtering.

      Global Filtering: For NetTL's Subsystems
      The below explained global filtering options apply only to NetTL's

      subystems.  NetTL's global filtering commands start with the word
      formatter, followed by the keywords verbosity, mode, option, or
      filter.

           formatter verbosity value,
                value should be either of

                                         error.  Same as the -v option.

                     low                 No internal debugging information
                                         is to be displayed.

                                         format.

                     nice                Enables "nice" formatting.  Same as
                                         -N option.

                     terse               Attempts to tersely format each

                                         Same as -1 (minus one) option.

                     normal              Normal formatting.

           formatter option [!] value,
                value should be

                     suppress            Normally repeated lines in hex
                                         output are condensed into a single
                                         line and a message stating that
                                         redundant lines have been skipped
                                         is displayed.  Specifying !suppress
                                         will print all redundant data.
                                         This is useful when the formatted
                                         output is used as input into other
                                         commands.

                     highlight           Normally the formatter will

                                         trace output in inverse video.
                                         Specifying !highlight will turn
                                         this feature off.  Same as the -l
                                         (minus ell) option.

                     formatter filter kind value [subsystem]
                          value can either be an established trace kind or a
                          mask.  A mask is a hexadecimal representation of a
                          (set of) trace kind(s).  Masks in multiple lines
                          are logically ``OR''ed.  The optional subsystem
                          name sets the kind filter only for the specified
                          subsystem.  Trace kinds and their corresponding

                     formatter filter log_instance value
                          value specifies the log instance number of the
                          messages to filter.  Selecting a log instance
                          allows the user to see the messages from a single
                          thread of network events.  Only one log instance
                          is allowed per filter configuration file.  The log
                          instance can not be negated with the ! operator.

                     formatter filter subsystem value
                          value specifies the subsystem name.  Available
                          subsystem names can be listed by using the
                          command:

                          formats all subsystems except those excluded by

                          subsystems (the default), use the * operator.  To
                          eliminate all subsystems, use the !* operator.

                     formatter filter time_from value
                     formatter filter time_through value
                          time_from indicates the inclusive starting time.
                          time_through indicates the inclusive ending time.
                          value consists of time_of_day and optionally
                          day_of_year, (usually separated by one or more
                          blanks for readability).

                          time_of_day specifies the time on the 24-hour
                          clock in hours, minutes, seconds and decimal parts
                          of a second (resolution is to the nearest
                          microsecond).  Hours, minutes and seconds are
                          required; fractional seconds are optional.
                          time_of_day format is hh:mm:ss.dddddd.

                          day_of_year specifies the day of the year in the
                          form month/day/year in the format: mm/dd/[yy]yy.
                          Specify month and day numerically, using one or
                          two digits.  For example, January can be specified
                          as 1 or 01; the third day of the month as 3 or 03.
                          Specify the year in four digits or by its last two
                          digits.  Only years in the ranges 1970-2037 are
                          accepted.  Two digit years in the range 70-99 are
                          interpreted as being in the 20th century (19xx)
                          and those in the range 00-37 are interpreted as
                          being in the 21st century (20xx) (all ranges
                          inclusive).  day_of_year is an optional field; the
                          current date is used as a default.

                          The time_from specification includes only those
                          records starting from the resolution of time
                          given.  For example, if the time_of_day for
                          time_from is specified as 10:08:00, all times
                          before that, from 10:07:59.999999 and earlier, are
                          excluded from the formatted output.  Records with
                          times of 10:08:00.000000 and later are included in
                          the formatted output.  Similarly, the time_through
                          specification includes only up to the resolution
                          of time given.  For example, if the time_of_day
                          for time_through is specified as 10:08:00, all
                          records with times after that, from
                          10:08:00.000001 onward, are excluded from the
                          formatted output.

    Subsystem Filtering    [Toc]    [Back]
      Note: Global filtering described above takes precedence over
      individual subsystem tracing and logging filtering described below.

      Subsystem filters are provided to allow filtering of data for
      individual subsystems or groups of subsystems.  Their behavior varies
      among individual subsystems.  Subsystem filters are valid only when
      the corresponding subsystems have been installed and configured on the
      system.  See the subsystem documentation for a description of
      supported subsystem filters and their behavior.

      Subsystem filtering commands start with the name of the subsystem
      followed by the subsystem filter keywords.  However, to provide

      convenience and backwards compatibility, several other filter keywords
      are provided for the group of LAN subsystems: NAME and FILTER.
      Currently, four types of subsystem filters are provided: LAN, X25,
      STREAMS, and OTS.  The collection of LAN subsystems use the subsystem
      filters identified by the FILTER and NAME keywords and the collection
      of OTS subsystems use the subsystem filters with the OTS keyword.  The
      collection of X25 subsystems start their filter commands with the X25
      subsystem names.

    LAN Naming and Filtering    [Toc]    [Back]
      LAN naming can be used to symbolically represent numbers with more
      recognizable labels.

           name nodename value
                nodename is a character string to be displayed in place of
                all occurrences of value.  value is a (IEEE802.3/Ethernet)
                hardware address consisting of 6 bytes specified in
                hexadecimal (without leading "0x"), optionally separated by
                -.  netfmt substitutes all occurrences of value with
                nodename in the formatted output.  The mapping is disabled
                when the -n option is used.  This option applies to tracing
                output only.

      LAN filtering is used to selectively format packets from the input
      file.  There are numerous filter types, each associated with a
      particular protocol layer:

           Filter Layer   Filter Type                  Description

      Filtering occurs at each of the five layers.  If a packet matches any
      filter within a layer, it is passed up to the next layer.  The packet
      must pass every layer to pass through the entire filter.  Filtering
      starts with Layer 1 and ends with Layer 5.  If no filter is specified
      for a particular layer, that layer is ``open'' and all packets pass
      through.  For a packet to make it through a filter layer which has a
      filter specified, it must match the filter.  Filters at each layer are
      logically ``OR''ed.  Filters between layers are logically ``AND''ed.

      LAN trace and log filters use the following format:

           filter type [!] value | *
                filter is the keyword identifying the filter as a LAN
                subsystem filter.

      The following filters are available for LAN tracing.

                subsystem indicated.

                range takes the form integer-integer, and indicates an
                inclusive set of events.

    X25 Naming and Filtering    [Toc]    [Back]
      The X25 product provides capabilities to assign symbolic names to
      important numbers and to filter log events and trace messages.  See
      x25log(1M) and x25trace(1M) for more information about X25 naming and
      filtering.

    OTS Filtering    [Toc]    [Back]
      The OTS subsystem filter allows filtering of the message ID numbers



 Hewlett-Packard Company           - 14 -   HP-UX 11i Version 2: August 2003






 netfmt(1M)                                                       netfmt(1M)




      that are typically found in the data portion of an OTS subsystem's log
      or trace record.  The OTS subsystem filter is effective for any
      subsystem that is a member of the OTS subsystem group.

      OTS trace filtering configuration commands have the following form in
      config_file:

           OTS [subsystem] msgid [!] message_ID | *

      Keywords and arguments are interpreted as follows:

           OTS            Identifies the filter as an OTS subsystem filter.

           subsystem      One of the following group of OTS subsystems:

                               OTS             ACSE_PRES         NETWORK
                               TRANSPORT       SESSION

                          Note: The absence of subsystem implies that the
                          filter applies to all OTS subsystems.

           message_ID     is the value of the message ID to filter.  A
                          message ID is used by OTS subsystems to identify
                          similar types of information.  It can be
                          recognized as a 4 digit number contained in
                          brackets ([ ]) at the beginning of an OTS
                          subsystem's trace or log record.  Initially all
                          message_IDs are enabled for formatting.  To format
                          records with specific message_IDs, turn off all
                          message IDs using the !* operator, then
                          selectively enable the desired message IDs.  Only
                          one message_ID is allowed on each line.  Multiple
                          lines are ``OR''ed together.

    STREAMS Filtering    [Toc]    [Back]
      The STREAMS subsystem filter allows filtering on some fields of the
      messages logged by STREAMS modules and drivers.  See strlog(7) for
      more information.

 EXTERNAL INFLUENCES    [Toc]    [Back]
    International Code Set Support
      Single- and multi-byte character code sets are supported in data.
      Single-byte character codesets are supported in filenames.

 DEPENDENCIES    [Toc]    [Back]
      netfmt only recognizes subsystems and filters from products which have
      been installed and configured.

 WARNINGS    [Toc]    [Back]
      The syntax that was used for the obsolete LAN trace and log options
      has been mixed with the syntax for the netfmt command such that any



 Hewlett-Packard Company           - 15 -   HP-UX 11i Version 2: August 2003






 netfmt(1M)                                                       netfmt(1M)




      old options files can be used without any changes.  The combination of
      syntax introduces some redundancy and possible confusion.  The global
      filtering options have the string formatter filter as the first two
      fields, while the LAN filtering options merely have the string filter
      as the first field.  It is expected that the older LAN filtering
      options may change to become more congruent with the global filtering
      syntax in future releases.

      The nettl and netfmt commands read the /etc/nettlgen.conf file each
      time they are executed.  These commands will not operate if the file
      becomes corrupted (see nettl(1M) and netfmt(1M)).

 DIAGNOSTICS    [Toc]    [Back]
      Messages describe illegal use of netfmt command and unexpected EOF
      encountered.

 EXAMPLES    [Toc]    [Back]
      The first group of examples show how to use command line options.

           1.  Format the last 50 records in file /var/adm/nettl.LOG000 (the
               default log file):

                   netfmt -t 50 -f /var/adm/nettl.LOG000

           2.  Use the follow option to send all log messages to the console
               (normally, only DISASTER-class log messages are sent to the
               console in console form):

                   netfmt -f  /var/adm/nettl.LOG000  -F  > /dev/console

           3.  Monitor all log messages in a hpterm window:

                   hpterm -e /usr/sbin/netfmt -F -f /var/adm/nettl.LOG000

           4.  Read file /var/adm/trace.TRC000 for binary data and use
               conf.file as the filter configuration file:

                   netfmt -c conf.file -f /var/adm/trace.TRC000

      The remaining examples show how to specify entries in the filter
      configuration file used with the -c option.

           1.  Tell netfmt to format only INFORMATIVE-class log messages
               coming from the NS_LS_IP subsystem between 10:31:53 and
               10:41:00 on 23 November 1993.

           4.  Format all packets transmitted from the local node, local, to
               the remote node, 192.6.1.3, which reference local TCP service
               ports login or shell, or remote UDP port 777:

                   filter         udp_dport      777

           5.  Format a TCP connection from local node node2 to 192.6.1.3
               which uses node2 service port ftp and remote port 1198.

                   filter         connection     node2:ftp    192.6.1.3:1198

           6.  Format all packets except those that use interface lan0:

                   filter         interface      ! lan0

           7.  Format all logged events for subsystem ip.  No other events
               are formatted.  (By default, all events are formatted):

                   filter         subsystem      ip   event      *

           8.  Format only event 5003 for subsystem ip.  Format all events
               except 3000 for subsystem tcp.  No other events are
               formatted.

                   filter         subsystem      ip    event  5003
                   filter         subsystem      tcp   event  *,!3000

           9.  Format only events 5003, 5004, 5005, and 5006 for subsystem
               ip.  Format all events except events 3000, 3002, and 3003 for
               subsystem tcp.  No other events are formatted:

                   filter      subsystem      ip    event  5003-5006
                   filter      subsystem      tcp   event  *,!3000,!3002-3003

           10. Format only those records containing message IDs 9973 and
               9974 for subsystem session and those not containing message
               ID 9974 for subsystem transport.  All records from other
               subsystems are formatted:

                   ots session    msgid          !*
                   ots session    msgid          9973
                   ots session    msgid          9974
                   ots transport  msgid          !9974

           11. Combine LAN and general filtering options into one
               configuration file.  Format 15 minutes of pduin and pduout
               data starting at 3:00 PM on 2 April 1990 for data from lan0
               interface.

                   formatter      filter       kind          0x30000000
                   formatter      filter       time_from     15:00:00 04/02/90
                   formatter      filter       time_through  15:15:00 04/02/90
                   filter         interface    !*
                   filter         interface    lan0
