Hi, I am a beginner, I want to use Dtrace to fetch TCP data from system and want to pass these data to a C program. I have few queries- 1. Is it possible that my Dtrace script hook on the TCP data (say using upcoming TCP provider), and then store these data in a shared memory ( in a queue). From this queue, pcapture ( a user defined function) simultaneously read the TCP data ? 2. We call pcapture (user defined function) with-in script itself, so every time DTRACE script hook on TCP data, pcapture is called for this. ( is it possible ? any tutorial ?) 3. We call TCP provider probe with-in pcapture function such that, these probe returns TCP data to pcapture. Basically i want to develop an application which captures Loop back TCP data packets on solaris 10. Any help ? thanks regards, Vijay This message posted from opensolaris.org
