[comp.protocols.tcp-ip] ETHERNET tapping

geminder@taurus.BITNET (04/10/91)

        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

I really enjoyed Tomer Geminder's request.

I'm not sure how many of you folks in are familiar with an American icon,
Maxwell Smart, a TV spy popular in the '60s, known for being quite a
bumbling fool (worse than Sellers' Inspector Clouseau).  Tomer's request
sounds like something from "Get Smart".  A sample snippet of dialog from
"Get Smart" goes something like this:

KAOS agent (disguised as a Trap-Net repairman):

	Mr. Smart, can you tell me where your hidden Trap-Net is, and
	how it works?

Maxwell Smart:

	It's the old 'KAOS-agent-asking-for-information-about-my-hidden-
	Trap-Net-trick'.  That's the oldest trick in the book.  Sorry, but
	I can't tell you that.

KAOS agent:

	But, I'm not a KAOS agent, I'm a Trap-Net repairman, and I'm here
	to do some preventative maintenance on your Trap-Net.  Got to keep
	those things oiled, you know.

Smart:

	Well, in that case, pretend that I am a KAOS agent.  I stand over
	here, and you, pretending to be me, can press that button over by
	the door.

[At this point, Trap-Net falls from ceiling trapping Smart.]

KAOS agent (in his German accent):

	You haff fallen into our trap, Herr Schmart!

Smart:

	Don't tell me you really are a KAOS agent!

KAOS agent:

	I am really a KAOS agent!

Smart:

	I asked you not to tell me that.
