|TRPT(8)||System Manager's Manual||TRPT(8)|
trptinterrogates 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,
trptprints all the trace records found in the system grouped according to TCP connection protocol control block (PCB). The options are as follows:
trptis as follows. 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
-Aoption to netstat(1). Then run
-poption, supplying the associated protocol control block addresses. The
-foption can be used to follow the trace log once the trace is located. If there are many sockets using the debugging option, the
-joption may be useful in checking to see if any trace records are present for the socket in question.
trptrequires the ability to open /dev/kmem which may be restricted based upon the value of the kern.allowkmem sysctl(8).
trptcommand appeared in 4.2BSD.
