Finding the originating host on a network login

[Mark Benard]

I am trying to determine how to find the 'foreign address' (such as
x.cs.tulane.edu.1234, as displayed by netstat -a) of a user who is
logged in via rlogin or telnet over the network.  Ideally, I
would like to be able to display a list of all users logged in and
the host or terminal server they are connected from.   (Note: last
displays this information, but only if rlogin was used.)

If there is no easy answer, then I guess that the question becomes:
netstat -A gives me protocol control blocks.  How do I determine the
process associated with a PCB?
