Hi, there.
In Linux box, How can I detect IP/MAC address duplication?
I'm using kernel-2.4.18 but the kernel does not seem to have
gratuitous arp implementation. Is it right?
I know I can detect IP address duplication by arping program
But I want to implment a following mechanism.
When the linux machine bootstraps or one of the nework interfaces
is assigned a MAC/IP address, the linux box can detect the duplication
of newly assigned MAC/IP address. How can I do this ?
thanks.

Hi Seong Moon,
the IPv6 implementation does duplicate address detection.
I'm not sure if this is similar to the ipv4 gratuitous ARP.
