TRPT(8N)                COMMAND REFERENCE                TRPT(8N)



NAME
     trpt - transliterate protocol trace

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

DESCRIPTION
     The trpt command interrogates the buffer of TCP trace
     records created when a socket is marked for "debugging" (see
     getsockopt(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 protocol control block (PCB).

     The recommended use of trpt is described here:
          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(1n).  Then run
          trpt with the -p option supplying the associated
          protocol control block addresses.  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.

OPTIONS
     -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.

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

     -p  Show only trace records associated with the protocol
         control block whose address follows.

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

FILES
     /vmunix
     /dev/kmem

DIAGNOSTICS
     Prints ``no namelist'' when the system image doesn't contain

     the proper symbols to find the trace buffer; prints other
     messages which should be self explanatory.

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

     Knowledge of tcp(4n), ip(4n), and udp(4n) is helpful in
     understanding the output formats of this utility.
