This is the situation that cause my problems:
I am in a lan with other 5-6 pc.
We have linux as operative system.
We installed dsniff because we are following a course of
Dsniff includes dnsspoof tool, now i don't know if this tool cause dns
spoofing (as the name) or dns poisoning, but the problem is that if a pc
is running with dnsspoof the other pc see the previously pc as dns
server. Now i don't know how defend my pc from this situation, iptables
permit to block a mac address but i don't want to block all mac address
of the lan to prevent the problem....
I hope i was more clear this time.
