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
