transliterate protocol trace
[ -a ] [ -s ] [ -t ] [ -f ]
[ -j ] [ -p hex-address ]
trpt interrogates the buffer of TCP
trace records created when a socket is marked for
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 following options may be used to
alter this behavior:
in addition to the normal output, print the values of the
source and destination addresses for each packet recorded
in addition to the normal output, print a detailed
description of the packet sequencing information
in addition to the normal output, print the values for all
timers at each point in the trace
follow the trace as it occurs, waiting a short time for
additional records each time the end of the log is reached
just give a list of the protocol control block addresses
for which there are trace records
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
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.
Should also print the data for each input or output,
but this is not saved in the trace record.
