40 .Nd transliterate protocol trace
46 .Op Fl p Ar hex-address
55 utility interrogates the buffer of
58 when a socket is marked for
62 and prints a readable description of these records.
63 When no options are supplied,
65 prints all the trace records found in the system
68 connection protocol control
72 The following options may be used to
74 .Bl -tag -width indent
76 In addition to the normal output,
77 print the values of the source and destination
78 addresses for each packet recorded.
80 Follow the trace as it occurs, waiting a short time for additional records
81 each time the end of the log is reached.
83 Just give a list of the protocol control block
84 addresses for which there are trace records.
86 Show only trace records associated with the protocol
87 control block at the given address
90 In addition to the normal output,
91 print a detailed description of the packet
92 sequencing information.
94 In addition to the normal output,
95 print the values for all timers at each
99 The recommended use of
102 Isolate the problem and enable debugging on the
103 socket(s) involved in the connection.
104 Find the address of the protocol control blocks
105 associated with the sockets using the
113 option, supplying the associated
114 protocol control block addresses.
117 option can be used to follow the trace log once the trace is located.
119 many sockets using the debugging option, the
121 option may be useful in checking to see if
122 any trace records are present for the socket in
125 If debugging is being performed on a system or
126 core file other than the default, the last two
127 arguments may be used to supplant the defaults.

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