trpt(1M)                                                 trpt(1M)



     NAME
          trpt - transliterate protocol trace

     SYNOPSIS
          /usr/etc/trpt [-a] [-j] [-phex-address] [-s] [-t]
          [system[core]]

     DESCRIPTION
          trpt prints a readable description of TCP trace records
          created when a socket is marked for debugging (see
          getsockopt(2N)).  When you don't supply an flag option, trpt
          prints all the trace records grouped according to TCP con-
          nection protocol control block (PCB).  The following flag
          options alter this:

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

          -j      list only the protocol control block addresses for
                  which there are trace records

          -phex-address
                  list only trace records associated with the hex-
                  address protocol control block

          -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

          system  used for debugging a system other than the default

          core    used for debugging a core file other than the de-
                  fault

          We recommend the following use of trpt.  Isolate the problem
          and enable debugging on the socket(s) involved in the con-
          nection.  Find the address of the protocol control blocks
          associated with the sockets using netstat -A (see
          netstat(1N)).  Then, run trpt -p and supply the associated
          protocol control block addresses.  If there are many sockets
          using the debugging flag option, you might want to use the
          -j flag option to check for any trace records for the socket
          in question.

     DIAGNOSTICS
          no namelist
               the system image doesn't contain the proper symbols to
               find the trace buffer.

          Other diagnostics are self explanatory.

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