You can temporarily turn this off on a Linux machine by issuing, "echo "0" > /proc/sys/net/ipv4/icmp_echo_ignore_broadcasts".

That appears to do it for multicasts, broadcasts and multicasts. However, broadcasts from outside the network should be blocked by the routers to prevent that attack. But multicasts and local broadcasts should still work, as happens with my A/V receiver. Is perhaps that setting a bit too agressive in blocking multicasts and local broadcasts, in addition to broadcasts? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
