How to solve the ARP attack under Linux

General Windows users can use the Antiarp firewall, but some computing professional friends for work or other reasons to use Linux system, then the Linux ARP attack how to do? The following is a master solution under the Linux Arp attack method, we can learn.

The Master is Fedora Core 6, first put a few mirror files hanging, with the keyword ARP a search, the search to Arptables, and Arpwatcher first is arpwatcher, it seems to only monitor the local Ip/arp address changes and so on, It does not seem to prevent ARP attacks. Another look arptables, immediately thought of iptables, loaded on a look, sure enough, the command line are identical. But the problem, keep the machine is not subject to ARP attack is very simple (with static ARP binding can be), but the others network Guan Ye or to be attacked, we are not network administrator, Gateway I can only "far view and can not be obscene play"!

Blocked, we diverted, arping this thing into my eyes, back to the shell, found has been installed pull:

"Arping-send ARP REQUEST to a neighbour host" arping [-ABDFHQUV] [-C Count] [-W deadline] [-s source]-I-Interface de Stination-u unsolicited ARP mode to update neighbours ' ARP caches. No replies are expected.
