Subject: Re: Arbitrary DDoS PoC

How do I subscribe only to the short list have to keep answering this 
bizarre way, so I apologize. If someone has an alternative way, please 
tell me.

I do not know what you expect of public repos at Github, really do not 
understand, you think that I would deliver the gold as well? Well, I 
think you're a guy too uninformed to find that the maximum is 200 
threads with pthread. Have you tried ulimit -a? I even described in the 
readme.

As the algorithm recaptcha, you really thought it would have all code in 
the main file? Why would I do that? I distributed in classes.

And why do you think IntensiveDoS accepts arguments and opens and closes 
a socket? Why is a snippet of code to not only HTTP DoS.

As for the trojan, you really think I would do something better and 
leave the public?

What planet do you live?

And Curl is a great project to parallel HTTP connections, python is not 
so much, and that is why only the fork stays with him.
