AW: AW: ARP Poisoning

O.k.
Let me tell you what I did.
I hat linux (redhat 7.3) and windows boxes (Win2k)
I was sending the arp spoof out of dsniff on a Win2k WS and the router. the
victim showed the "same ip on network)
as i did it between the router and the linux, i pinged the router ip from
the victim and it showed the redirect to the router.
i did not have the time to test it out to much (was a tcp/ip class)

Mit freundlichen Grüßen/ sincerely yours

Hello Bernhard,
You are right. Some Windows recognize an arp-poisoning,
but in this case you have to "arp-storm" only the
others(not the windows victim).
Then poison the windows-arp-cache in the name of the
router(,gateway,...) and the same with the
router-arp-cache.
And the 2nd if u ping the router (router ip) you ping
not the router.You ping the poisoner (me). Because your
arp cache think i am the router.And i answer u with a
ping. So even on linux u dont find me.
Only solution is to look in the arp-cache if it is
poisoned.
For beginner "ettercap" will do a good job. In this
programm is a point "looking for other poisoners".
So you might find me.

Hi Michael!

I did not test it out too much, but if you are in the
same network =
windows
will warn that the same IP-Adress is twice on the net.
On Linux you see it, if you ping the router, he shows
that the ping is
redirected.
can anyone verify this? other than that ?????

Mit freundlichen Gr=FC=DFen/ sincerely yours
