TRPT(8C)
MAINTENANCE COMMANDS
TRPT(8C)
NAME
trpt - transliterate protocol trace
SYNOPSIS
/usr /etc/trpt ( -a ) ( -s ) (-t ) (
-J ) (
-phez-tJddre88 ) (
system ( core) )
DESCRIPTION
Trpt interrogates the buffer of TCP trace records created when a socket is marked for 'debugging'
(see 8et8ockopt(2)), and prints a readable description of these records. When no options are sup-
plied, Irpl
prints all the trace records found in the system grouped according to TCP connection
protocol control block (PCB).
OPTIONS
FILES
-. Print a detailed description of the packet sequencing information, in addition to the nor-
. mal output.
-t Print the values for all timers at each point in the trace, in addition to the normal out.-
put.
-J
Just give a list of the protocol control block addresses for which there are trace records.
-ph ez- addre8'
Show only trace records associated with the protocol control block who's address follows.
-a in addition to the normal output, print the values of the source and destination addresses
for each packet recorded.
The recommended use of
Irpl
is as follows. Isolate the problem and enable debugging on the
socket(s) involved in the connection. Find the addreM of the protocol control blocks associated
with the sockets using the -A option to
net8ItJt(8).
Then run
Irpl
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.
It debugging is being performed on a system or core file other than the default, the last two argu-
ments may be ueed to supplant the defaulte.

DIAGNOSTICS
'no namelist j when the system image doesn't contain the proper symbols to find the trace buffer;
others which should be self explanatory.
BUGS
Should also print the data for each input or output, but this
is
not saved in the race record.
The output format is inscrutable, and should be described here.
