The Id line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;
.\" $Id$
.\"
If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

.Sh DESCRIPTION
|
|
.Nm Trpt
|
|
interrogates the buffer of
|
|
.Tn TCP
|
|
trace records created
|
|
when a socket is marked for
|
|
.Dq debugging
|
|
(see
|
|
.Xr setsockopt 2 ) ,
|
|
and prints a readable description of these records.
|
|
When no options are supplied,
|
|
.Nm
|
|
prints all the trace records found in the system
|
|
grouped according to
|
|
.Tn TCP
|
|
connection protocol control
|
|
block
|
|
.Pq Tn PCB .
|
|
The following options may be used to
|
|
alter this behavior.
|
|
.Bl -tag -width indent
|
|
.It Fl a
|
|
In addition to the normal output,
|
|
print the values of the source and destination
|
|
addresses for each packet recorded.
|
|
.It Fl f
|
|
Follow the trace as it occurs, waiting a short time for additional records
|
|
each time the end of the log is reached.
|
|
.It Fl j
|
|
Just give a list of the protocol control block
|
|
addresses for which there are trace records.
|
|
.It Fl p
|
|
Show only trace records associated with the protocol
|
|
control block at the given address
|
|
.Ar hex-address .
|
|
.It Fl s
|
|
In addition to the normal output,
|
|
print a detailed description of the packet
|
|
sequencing information.
|
|
.It Fl t
|
|
In addition to the normal output,
|
|
print the values for all timers at each
|
|
point in the trace.
|
|
.El
|
|
.Pp
|
|
The recommended use of
|
|
.Nm
|
|
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
|
|
.Fl A
|
|
option to
|
|
.Xr netstat 1 .
|
|
Then run
|
|
.Nm
|
|
with the
|
|
.Fl p
|
|
option, supplying the associated
|
|
protocol control block addresses.
|
|
The
|
|
.Fl 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
|
|
.Fl j
|
|
option may be useful in checking to see if
|
|
any trace records are present for the socket in
|
|
question.
|
|
.Pp
|
|
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.

When the system image doesn't

|
contain the proper symbols to find the trace buffer;

.Sh BUGS
|
|
Should also print the data for each input or output,
|
|
but this is not saved in the trace record.
|
|
.Pp
|
|
The output format is inscrutable and should be described
|
|
here.
