NAME
      trpt - transliterate protocol trace

SYNOPSIS
      trpt [ -afjst ] [ -p hex-address ] [ system [ core ] ]

DESCRIPTION
      trpt interrogates the buffer of TCP trace records created when a socket
      is marked for debugging [see getsockopt(3N)], and prints a readable
      description of these records.  When no options are supplied, trpt prints
      all the trace records found in the system grouped according to TCP
      connection protocol control block (PCB).  The following options may be
      used to alter this behavior.

OPTIONS
      -a    In addition to the normal output, print the values of the source
            and destination addresses for each packet recorded.

      -f    Follow the trace as it occurs, waiting a short time for additional
            records each time the end of the log is reached.

      -j    Just give a list of the protocol control block addresses for which
            there are trace records.

      -s    In addition to the normal output, print a detailed description of
            the packet sequencing information.

      -t    In addition to the normal output, print the values for all timers
            at each point in the trace.

      -p hex-address
            Show only trace records associated with the protocol control block,
            the address of which follows.

      The recommended use of trpt is as follows.  Isolate the problem and
      enable debugging on the socket(s) involved in the connection.  Find the
      address of the protocol control blocks associated with the sockets using
      the -A option to netstat(1M).  Then run trpt with the -p option,
      supplying the associated protocol control block addresses.  The -f option
      can be used to follow the trace log once the trace is located.  If there
      are many sockets using the debugging option, the -j option may be useful
      in checking to see if any trace records are present for the socket in
      question.

      If debugging is being performed on a system or core file other than the
      default, the last two arguments may be used to supplant the defaults.

DIAGNOSTICS
      no namelist
            When the system image does not contain the proper symbols to find
            the trace buffer; others which should be self explanatory.

NOTES
      Should also print the data for each input or output, but this is not
      saved in the trace record.

      The output format is inscrutable and should be described here.
