怎么才不会被ping到？

以前用linux时好像看到一个不响应ping的命令， 好长时间也不记得了！ 不过应该也可以用在FreeBSD下吧！

echo "echo 1 >/proc/sys/net/ipv4/icmp_echo_ignore_all">>/etc/rc.d/rc.local

请问系统启动时是先读取/etc/rc.conf还是 /etc/defaults/rc.conf的内容？

要是两个矛盾，要哪个文件的配置？

国外一个回答：

Find out what a packet filter is
Decide on which packet filter you want to use
Install a packet filter
Learn how to use the packet filter
Configure packet filter to reject incoming ICMP packets directed to the box itself

Be sure to allow ICMP type 3 packets, otherwise you will break certain connections. Search the forums for discussions of the various ICMP types and which ones to allow/block.

如果需要配置请配置/etc/rc.conf，千万不要修改/etc/defaults/rc.conf文件，原来看见的那篇文章讲得非常清楚，但还是没找到，唉，
