[Bro] new to bro, a few questions

[John Brown (isFaster)]

Hi,  I'm new to Bro and I'm wondering how I can do a couple of things:

1.  I'd like to basically disable all of the various rules and detection
stuff.
2. I'd like to create a simple rule that detects say DNS packets with
cpsc.gov in the query or answer

Figure it would be best to start simple and then build up rules (either my
own, or others) as I need them.   Sort of a K&R "Hello World" approach..

Any specifics would be much appreciated.


Thank you
