23: trsp \- transliterate sequenced packet protocol trace

38: .SH DESCRIPTION
39: .I Trpt
40: interrogates the buffer of SPP trace records created
41: when a socket is marked for \*(lqdebugging\*(rq (see
42: .IR setsockopt (2)),
43: and prints a readable description of these records.
44: When no options are supplied,
45: .I trsp
46: prints all the trace records found in the system
47: grouped according to SPP connection protocol control
48: block (PCB). The following options may be used to
49: alter this behavior.
50: .TP
51: .B \-s
52: in addition to the normal output,
53: print a detailed description of the packet
54: sequencing information,
55: .TP
56: .B \-t
57: in addition to the normal output,
58: print the values for all timers at each
59: point in the trace,
60: .TP
61: .B \-j
62: just give a list of the protocol control block
63: addresses for which there are trace records,
64: .TP
65: .B \-p
66: show only trace records associated with the protocol
67: control block who's address follows,
68: .TP
69: .B \-a
70: in addition to the normal output,
71: print the values of the source and destination
72: addresses for each packet recorded.
73: .PP
74: The recommended use of
75: .I trsp
76: is as follows.
77: Isolate the problem and enable debugging on the
78: socket(s) involved in the connection.
79: Find the address of the protocol control blocks
80: associated with the sockets using the
81: .B \-A
82: option to
83: .IR netstat (1).
84: Then run
85: .I trsp
86: with the
87: .B \-p
88: option, supplying the associated
89: protocol control block addresses. If there are
90: many sockets using the debugging option, the
91: .B \-j
92: option may be useful in checking to see if
93: any trace records are present for the socket in
94: question.
95: .PP
96: If debugging is being performed on a system or
97: core file other than the default, the last two
98: arguments may be used to supplant the defaults.

103: .SH "SEE ALSO"
104: netstat(1), setsockopt(2)
105: .SH DIAGNOSTICS
106: ``no namelist'' when the system image doesn't
107: contain the proper symbols to find the trace buffer;
108: others which should be self explanatory.
109: .SH BUGS
110: Should also print the data for each input or output,
111: but this is not saved in the race record.
112: .PP
113: The output format is inscrutable and should be described
114: here.
