Pyloris

PyLoris is a scriptable tool for testing a service's level of vulnerability to a particular class of Denial of Service (DoS) attack.
Any service that places restrictions on the total number of simultaneous TCP connections has the potential for vulnerability to PyLoris.
Additionally, services that handle connections in independent threads, services that poorly manage concurrent connections, and services that have high memory footprint per connection are prone to this form of vulnerability.
You can download pyloris from here.
PyLoris 3.0 requires Python 2.x to run.
For launch pyloris you can use idle python, or terminal:
python pyloris.py
You can use pyloris with tor and choose between HTTP, SOCKS4 and SOCKS5 proxy.
Pyloris is avaible for all platform.
