37 .Nd transliterate protocol trace
43 .Op Fl p Ar hex-address
52 utility interrogates the buffer of
55 when a socket is marked for
59 and prints a readable description of these records.
60 When no options are supplied,
62 prints all the trace records found in the system
65 connection protocol control
69 The following options may be used to
71 .Bl -tag -width indent
73 In addition to the normal output,
74 print the values of the source and destination
75 addresses for each packet recorded.
77 Follow the trace as it occurs, waiting a short time for additional records
78 each time the end of the log is reached.
80 Just give a list of the protocol control block
81 addresses for which there are trace records.
83 Show only trace records associated with the protocol
84 control block at the given address
87 In addition to the normal output,
88 print a detailed description of the packet
89 sequencing information.
91 In addition to the normal output,
92 print the values for all timers at each
96 The recommended use of
99 Isolate the problem and enable debugging on the
100 socket(s) involved in the connection.
101 Find the address of the protocol control blocks
102 associated with the sockets using the
110 option, supplying the associated
111 protocol control block addresses.
114 option can be used to follow the trace log once the trace is located.
116 many sockets using the debugging option, the
118 option may be useful in checking to see if
119 any trace records are present for the socket in
122 If debugging is being performed on a system or
123 core file other than the default, the last two
124 arguments may be used to supplant the defaults.
126 .Bl -tag -width /dev/kmem -compact

134 contain the proper symbols to find the trace buffer;
135 others which should be self explanatory.
146 Should also print the data for each input or output,
147 but this is not saved in the trace record.
149 The output format is inscrutable and should be described
