trpt(8c)							      trpt(8c)

Name
       trpt - transliterate protocol trace

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

Description
       The command interrogates the buffer of TCP trace records created when a
       socket  is  marked  for	debugging and prints a readable description of
       these records.

Options
       When no options are supplied, 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:

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

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

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

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

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

       The  recommended	 use of is to 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 Then run with the -p option, supplying the associated protocol  con‐
       trol  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.

Diagnostics
       no namelist
       The system image does not contain the proper symbols to find the	 trace
       buffer.

       Other diagnostic messages are self-explanatory.
