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.

With the recent wave of DDoS, a concern that was not taken is the
model
where the zombies were not compromised by a Trojan. In the standard
modeling of DDoS attack, the machines are purchased, usually in a
VPS,
or are obtained through Trojans, thus forming a botnet. But the
arbitrary shape doesn't need acquire a collection of computers.
Programs, servers and protocols are used to arbitrarily make
requests on
the target. P2P programs are especially vulnerable, DNS, internet
proxies, and many sites that make requests of user like Facebook
or W3C,
also are.
Precisely I made a proof-of-concept script of 60 lines hitting
most of
HTTP servers on the Internet, even if they have protections likely
mod_security, mod_evasive. This can be found on this link [1] at
GitHub.
The solution of the problem depends only on the reformulation of
protocols and limitations on the number of concurrent requests and
totals by proxies and programs for a given site, when exceeded
returning
a cached copy of the last request.
