There are better ways to test Snort. Snort doesn't have a formal programmatic SYN flood detector but you could probably write a threshold rule that would give you the capability in about 10 minutes.

A better idea would be to go get metasploit or the Exploitation Framework at http://www.securityforest.com/wiki/index.php/ Exploitation_Framework to generate some attacks. Snort has never really concentrated on rate-based DoS detection. Usually you can tell when you're getting hit by a rate-based DoS without a whole lot in the way of IDS... :)

HI...

I donwload a couple of tools form this site:

http://www.antiserver.it/Denial-Of-Service/

The tools were:

APSEND v1.60 and

Datapool v3.3

I used them to test my linux box with snort, but i don't get any alerts on any of the atacks, only portscans and portsweeps but no DoS attacks. For example with apsend you can genered a syn flood DoS... but snort will not generate and alerts...

So i like to know what i'm doing wrong or is there a better way to test snort...

Thanks
