trpt(8c) trpt(8c) Name trpt - transliterate protocol trace Syntax trpt [ -a ] [ -s ] [ -t ] [ -j ] [ -p hex-address ] [ system [ core ] ] Description The command interrogates the buffer of TCP trace records created when a socket is marked for debugging and prints a readable description of these records. Options When no options are supplied, prints all the trace records found in the system grouped according to TCP connection protocol control block (PCB). The following options may be used to alter this behavior: -s In addition to the normal output, prints a detailed description of the packet sequencing information. -t In addition to the normal output, prints the values for all timers at each point in the trace. -j Gives a list of the protocol control block addresses for which there are trace records. -p Shows only trace records associated with the protocol control block whose address follows. -a In addition to the normal output, prints the values of the source and destination addresses for each packet recorded. The recommended use of is to 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 -A option to Then run with the -p option, supplying the associated protocol control block addresses. If there are many sockets using the debugging option, the -j option may be useful in checking to see if any trace records are present for the socket in question. 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. Diagnostics no namelist The system image does not contain the proper symbols to find the trace buffer. Other diagnostic messages are self-explanatory. Files See Also netstat(1), setsockopt(2) trpt(8c)
