I'm not sure what problem it is, but i am using Nam 1.14 on Ubuntu 9.04.<br />Sorry for my poor english.<br />Actually i just want to create 4 nodes to test the ping flood. that mean Node 1 is server, connecting with other 3 nodes. Nodes 4 is attacker which ping flooding the server, another two nodes fail to request service from the server because Nodes 4 is exhausted all bandwidth from server. Do my concept have anything wrong?
