DoS Step-by-Step: Testing Broadcast Amplification from FreeBSD


Revision: 1.4 - Date: 2000/03/23 03:19:31 GMT

% /usr/etc/ping -c 10 -s 1 -q <Network-or-Broadcast-IP-Address>

This will send ICMP Echo Request packets with a data length of 1 byte, and wait for 10 requests to be sent.

If your network is acting as an amplification site you will see something like this containing "-XXX% packet loss":

----xx.yy.zz.255 PING Statistics----
3 packets transmitted, 27 packets received, -800% packet loss

If your ping results are showing "- (negative) packet loss" go back to Step 2.1.

If your network is NOT acting as an amplification site you will see something like this containing "100% packet loss":

--- xx.yy.zz.0 ping statistics ---
10 packets transmitted, 0 packets received, 100% packet loss
