title: hping3 Syn Flood attack (DoS) is not strong enough
body: <p>I'm building an environment to test SynFlood attack. I have 3 VMs to represent SaveClient, Attacker, and the Victim. All are running on VirtualBox. They have Ubuntu 16.04 LTS server with the same configuration (1GB RAM, 1 processor). </p>
  
  <p>I tried to establish the attack with hping3 as following:</p>
  
  <pre><code>sudo hping3 Victim_IP -p 44 --rand-source -c 1000000 -d 120 -S -w 64 --flood  
  </code></pre>
  
  <ul>
  <li>There is no server running on the Victim client on port 44. </li>
  </ul>
  
  <p>I tried to ping or send a file with nc (netcat) from the SaveClient to the Victim, and i was expecting that the victim is down. However, pinging the Victim or sending files are succeeded with no problem.</p>
  
  <p>My questions:</p>
  
  <ol>
  <li>Do I need to run a server (e.g. Tomcat or other HTTP servers) on
  port 44 at the victim to establish a correct testbed? </li>
  <li>What are other tools required to establish a working SynFlood attack in this
  environment?</li>
  </ol>
  
  <p>All suggestions are welcomed. </p>
