TRPT(8) BSD System Manager's Manual TRPT(8) NNAAMMEE ttrrpptt - transliterate protocol trace SSYYNNOOPPSSIISS ttrrpptt [--aa] [--ff] [--jj] [--pp _h_e_x_-_a_d_d_r_e_s_s] [--ss] [--tt] [_s_y_s_t_e_m [_c_o_r_e]] DDEESSCCRRIIPPTTIIOONN TTrrpptt interrogates the buffer of TCP trace records created when a socket is marked for ``debugging'' (see setsockopt(2)), and prints a readable description of these records. When no options are supplied, ttrrpptt prints all the trace records found in the system grouped according to TCP con- nection protocol control block (PCB). The following options may be used to alter this behavior. --aa In addition to the normal output, print the values of the source and destination addresses for each packet recorded. --ff Follow the trace as it occurs, waiting a short time for addition- al records each time the end of the log is reached. --jj Just give a list of the protocol control block addresses for which there are trace records. --pp Show only trace records associated with the protocol control block at the given address _h_e_x_-_a_d_d_r_e_s_s. --ss In addition to the normal output, print a detailed description of the packet sequencing information. --tt in addition to the normal output, print the values for all timers at each point in the trace. The recommended use of ttrrpptt is as follows. Isolate the problem and en- able debugging on the socket(s) involved in the connection. Find the ad- dress of the protocol control blocks associated with the sockets using the --AA option to netstat(1). Then run ttrrpptt with the --pp option, supplying the associated protocol control block addresses. The --ff option can be used to follow the trace log once the trace is located. If there are many sockets using the debugging option, the --jj option may be useful in checking to see if any trace records are present for the socket in ques- tion. The 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.
