/usr/src/linux/include/linux/icmp.h
/usr/src/linux/Documentation/networking/ip-sysctl.txt
ipchains -h icmp
RFC 792

to protect from ping of death

echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_all

or use ipchains instead

ipchains -A input -p icmp -s ! <network_segment/mask> echo-request -d
<ip_address_of_your_server> -j DENY

this command cannot ping your server with a source ip address outside your network
segment.
