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 ;-) _T
