Re: mac to ip address tools

In case of ARP poisoning attack, arpwatch will help you. You could also
detect those poisoning and its promiscious mode using same tool like
Ettercap.

yeah. There are about 500-600 machines in this place, I say this because
these are the registered machines. What about those not registered?
there is one thing that bother them is that when we tried to use arp it
seems that they are about 100  machines  with the same mac address.
Wonder could this be the the machines here have been poisoned?
