Hmm.  Are the interfaces configured properly on both machines?
I know I've pulled my hair many times before realizing I misset
the broadcast or something like that.  Spray and ping
shouldn't rely on /etc/ethers at all and should only rely
on /etc/hosts if you specify the target in hostname format.

Do an 'ifconfig le0' and confirm that both machines are
using the same broadcast, same netmask, same trailers (we
prefer none).

And of course check that the interfaces are up ;-)
