3. how to do I stop the server from responding to
pinging?
Running FreeBSD 4.2 and 6.1.
I changed the /etc/rc.network file to "NO" for
broadcast ping responses, and this did not work (still
responding to ping) when I rebooted:
case ${icmp_bmcastecho} in
[Yy][Ee][Ss])
echo -n ' broadcast ping responses=NO'
sysctl net.inet.icmp.bmcastecho=1
>/dev/null
