HULK DoS tool ported to Go language from Python. Original Python utility by Barry Shteiman http://www.sectorix.com/2012/05/17/hulk-web-server-dos-tool/

I just ported utility as is quick and dirty. Original functions names are keeped and original logic mostly keeped too. Minor features added:

• you may set custom number of threads used for requests
• also set number of CPU cores used by program (nice Go feature)
• program correctly killed by Ctl+C

This tool targeted for load testing and may really down badly configured server. Use it wisely.

Examples:

$ hulk -site http://example.com/test/ 2>/dev/null

$ HULKMAXPROCS=4096 hulk -site http://example.com 2>/tmp/errlog

Useful environment vars:

• GOMAXPROCS Set it to number of your CPUs or higher.
• HULKMAXPROCS Limit the connection pool (1024 by default). To create high load use higher values.
