OK, this sounds Really Wacky (or, Really Hacky if you're into puns) but =
there's a reason for it, I swear...
Will typical OSS UNIX kernels (Linux, BSD, MacOS X, etc) reply to a =
crafted ARP request that, instead of having FF:FF:FF:FF:FF:FF as its =
destination MAC address, is instead sent to the already-known unicast =
MAC address of the host?=20
Next, what would be your utility of choice for crafting such a packet? =
Or is this something one would need to code up by hand in a lower-level =
language?
Thanks,
