Port Groper is an open source denial of service tool written in Java. It works by using proxies as bots.

Typical Port Groper Usage:
1. Can be used to benchmark firewalls for IP banning of DoS attacks to a specific port.
2. Can be used to distort website tracking information (such as Google Analytics).
3. Can be used to distort web-page hits (or hits per day).
4. Can bring down single (non clustered, or poorly clustered) servers.

While Port Groper can be used for DoS attacks; I hold absolutely no responsibility or liability for those that use this tool in such a way.

All builds after 3.2 (including 3.2) require java 7.

Port Groper v2 is built with java 6.

Port Groper v1 is written in python and requires python 2.7 (exe version does not require python 2.7 to be installed)

Port Groper Web Site
