|
|
|
The
|
|
|

.Nm
|

utility interrogates the buffer of
|
1994-05-26 05:23:31 +00:00
|
|
|
.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.

.Nm

each time the end of the log is reached.

Just give a list of the protocol control block

Show only trace records associated with the protocol

print the values for all timers at each

The recommended use of

|
|
|
.Nm
|
1994-05-26 05:23:31 +00:00
|
|
|
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
|
2001-07-15 08:06:20 +00:00
|
|
|
associated with the sockets using the
|
1994-05-26 05:23:31 +00:00
|
|
|
.Fl A
|
2001-07-15 08:06:20 +00:00

1994-05-26 05:23:31 +00:00
|
|
|
.Xr netstat 1 .

1997-10-22 06:23:12 +00:00
|
|
|
.Nm
|
1994-05-26 05:23:31 +00:00

|
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.
