Disabling the ARP Protocol in Linux Box

Question

I need to disable the system level ARP protocol to perform some experiment on my Ubuntu 11.10 system.

So please help me in disabling the ARP module/protocol in my system.

Are you willing to dive into the source code of linux to disable it? ARP is a critical protocol for IPv4 and IPv6. If you disable it you won't be able to use any IP services from your machine — SecurityMatt, Mar 11, 2012 at 17:04
please clarify what you mean by 'disabling system-level arp'... what do u want not to work, exactly? — user1055604, Mar 14, 2012 at 18:35

To supress ARP on interface eth0 run the following command as root:

ip link set dev eth0 arp off

To turn it back on again:

ip link set dev eth0 arp on

I know that ip is newer and more powerful than ifconfig but ifconfig eth0 -arp( turning off) and ifconfig eth0 arp (turning on) also works.
