There is a utility called "ofiles", which we obtained from Vic Abell, 
abe at mace.cc.purdue.edu in March 1989, that does this. Specifically, it can 
take the output of "netstat -A" and use the PCB addresses given to tell you 
which process owns each TCP connection. I recently hacked this on our Sequent 
Balance machine, so that the PCB value printed for UDP sockets is interpreted 
as the address of the inpcb structure; this is true for Dynix but not for BSD 
4.2.
