Subject: Re: [Tool] - inundator - an intrusion detection
	false positives generator.

One more thing, just for the records and being polite: nobody works on such "bad idea" anymore... Why? Because doesn't make any sense you doing so many noise to evade an IPS. There much more effectiveness ways to do it without "scream wolf", little boy.

Best regards.

PS: Keep playing with "incubator" and let the real work for the pros.
