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


Revision: 1.4 - Date: 2000/03/23 03:23:25 GMT

% /bin/ping -c 10 -s 1 -q -b <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 duplicates":

--- ping statistics ---
10 packets transmitted, 10 packets received, +369 duplicates, 0% packet loss

If your ping results are showing "duplicates" go back to Step 2.1.
