On Linux, strace will show all the system calls a process makes (including
all I/O).  You can see exactly what file or port is opened, what data is
read or written, etc.  On SVR4, the truss program does the same thing.
I've heard that FreeBSD has a ptrace program that works the same way,
but I've never used that one personally.  And for network traffic,
as you mentioned, there are packet analyzers.

Of course, some people are stuck with "operating systems" that don't
provide this level of functionality.... :-)
