 Так постил уже :)
 
 Вот что было в багреке:
 
 Here is a patch http://securitylab.ru/_tools/antidote2.diff.gz for linux
 kernel (2.4.18 and .19 tested) to resisting ARP spoofing.
 
 If applied, it brings a new sysctl parameter:
 
 net.ipv4.neigh.<interface name>.arp_antidote
 
 that defines kernel behaviour when changes in correspondence between MAC
 and IP are detected.
 
 Parameter value 0 corresponds standart behaviour, ARP cache will be
 silently updated.
 
 Value=1..3 corresponds "verification" behaviour. Kernel will send ARP
 request to test if there is a host at "old" MAC address. If such
 response received it lets us know than one IP pretends to have
 several MAC addresses at one moment, that probably caused by ARP spoof
 attack.
 
 Value=1 - just report attack and ignore spoofing attempt.
 Value=2 - ARP cache record will be marked as "static" to prevent attacks
 in future.
 Value=3 - ARP cache record will be marked as "banned", no data will be
 delivered to attacked IP anymore, untill system administrator unban
 ARP record updating it manually.
