** The following is a trimmed version of two seperate DTrace scripts:

** socketsnoop.d - snoop TCP network socket traffic by process.
**  This is intended to identify the process responsible
**  for network traffic. Written in DTrace (Solaris 10 build 63).
**
** iosnoop.d - A program to print I/O events as they happen, with useful
**      details such as UID, PID, inode, command, etc.
**      Written in DTrace (Solaris 10 build 63).
