We are about to launch a important webservice. We must test it for DDoS. From other questions/answers here I learned about LOIC. Downloaded, tried, but my apache refuses it.

What other ready made tools are out there so I could CRITICALLY test our serwice?

Any good tutorials on how to do it via shell/bash?

  • LOIC is a joke, the only reason why it worked is because hundreds of thousands of people where running it.

You can try tools like Seige, BoNSI from Backtrack, these are easy to use and "program name -help" should guide you. If you are looking something commercial then http://blitz.io is another option.
