        I come from a very secured installation which now have to expand
and allow access from LAN's (mainly ETHERNET). I claim that even when we
use a router with allows us to control ETHERNET addr. of a host aginst its
IP addr. it is not enougth to prevent a user on the ETHERNET from tapping
to others, and even from pretending to other host. But to make my point
clear to the LAN user who does not understand why I claim that all the LAN
usesrs are equal in my point of view, I need to show him how it can be doen
in practice.
        Is whould thank anyone who will be willing to mail me names of
products, or program of its oun which can tap to ETHERNET and format the
received information into readable format. I look also for names of
workstations and PC boards which their ETHERNET address is writen in the
software and is not hardware fixed.



    Thanks in advance
