doubt it's been listed yet, but from what I see backtrack 4 pre-final doesn't have a terminal-based program called Hyenae. Hyenae seems to be updated quite often from what I've seen and it works well to, anyways just a thought to add it to the list of requests, hope to see it on. :)
Hyenae is a highly flexible platform independent network packet generator. It allows you to reproduce several MITM, DoS and DDoS attack scenarios, comes with a clusterable remote daemon and an interactive attack assistant.
