zaptor:freitasm: You're completely missing the point or trying to create something that doesn't exist.
DDoS are not testing tools. It will affect networks as it goes through.
AFAIK these DDoS services exist under the (false?) guise that they provide a legitimate service. Well, that seems to be the rationale anyhow.
These are legal like those Russian-based websites selling mp3 are legal... In other words NO, they aren't.
some people buy mp3 on Russian sites and say "I paid for it, so it must be legal", not thinking they are handing out their credit card details to a bunch of pirates. Paying for something doesn't make it legal.
DDoS services are not legal.
zaptor:plambrechtsen: If you are doing it as per your example on a local LAN then that's fine...
I believe that's what I was trying to clarify for you, since you said "DDoS of any type isn't legal".
Again you are confusing LOAD TESTING with DDOS. Different things. VERY different things.
