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](http://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

You may want to look at Bro’s “bare mode”. It starts Bro without many of Bro’s features.
