1. How do I stop others from port scanning a server? 

2. is stopping the response to pinging enough?

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
                ;;
