DoS/DDoS attack testing

hi all - can anybody think of a good way to test my DDoS firewall and defenses? it seems lately i have been getting hit pretty hard. i wish to be able to simulate a DoS attack to see if my csf-firewall stands up to the challenge.

Howdy,

Benchmarking software can do a pretty good job at also looking like a denial of service attack.

A simple one that most servers already have installed is called "ab", or "Apache Bench". It comes with Apache, and can be used to "hammer" on Apache to assist in testing.

thank you eric. i would think something like apache bench might be interesting since the tester and the test subject would be on the same IP number - i wonder if that is a fair test ?

your benchmarking software suggestion lead me to this:

this looks interesting.

Howdy,

Well, you don't need to run it from the same machine as you want to test... you can install Apache bench on another server, on a desktop, or anywhere you like, and run it from there.

Apache bench simply opens http connections to the server you tell it to access.
