    NAME
         trpt - transliterate protocol trace

    SYNOPSIS
         trpt [ -a ] [ -s ]  [ -t ] [ -f ] [ -j ] [ -p hex-address ]
         [ system [ core ] ]

    DESCRIPTION
         Trpt interrogates the buffer of TCP trace records created
         when a socket is marked for "debugging" (see setsockopt(2)),
         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 pro-
         tocol control block (PCB).  The following options may be
         used to alter this behavior.

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

         -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.

         -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.

         -p   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(1).  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.
         The

         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 doesn't contain the
         proper symbols to find the trace buffer; others which should
         be self explanatory.

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

         The output format is inscrutable and should be described
         here.
