ddosim is a tool that can be used in a laboratory environment to simulate a distributed denial of service (DDOS) attack against a target server. The test will show the capacity of the server to handle application specific DDOS attacks. ddosim simulates several zombie hosts (having random IP addresses) which create full TCP connections to the target server. After completing the connection, ddosim starts the conversation with the listening application (e.g. HTTP server). ddosim is written in C++ and runs on Linux. Its current functionalities include: HTTP DDoS with valid requests HTTP DDoS with invalid requests (similar to a DC++ attack) SMTP DDoS TCP connection flood on random port In order to simulate such an attack in a lab environment we need to setup a network like this: Download :   ddosim-0.2.tar.gz More Info : 1)   DDOSIM at Sourceforge
