trpt(8c)trpt(8c)Nametrpt - transliterate protocol trace
Syntaxtrpt [ -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.
