   have a 'tool' for this? ideas?

Check out the "ofiles" program, available in the comp.sources.unix
archives.  It can determine open file descriptors for specified
process ID's, or processes which currently have open file descriptors
on any specified device, or processes which have specific files open.
I don't think it can determine a PID given an open network socket,
especially since not all active network sockets are guaranteed to be
associated with a PID (for example, if a program using a socket
terminates prematurely, its socket may hang around for a while before
it goes away).
