Hi,

I have update with master branch of Bro (still Bro 1.6).

But I find that currently, by default, Bro will generate conn.log, noitice\_policy.log and packet\_filter.log without indicating any bro policy script. I am wondering is there any way that I can disable them.

Best,

Hui

That's actually called 2.0, there isn't really a 1.6. 😉

Search for "disable\_stream" in the logging framework documentation:  
&nbsp;&nbsp;[http://www.bro-ids.org/documentation-beta/logging.bro.html](http://www.bro-ids.org/documentation-beta/logging.bro.html)

The streams you're looking to disable are:  
&nbsp;&nbsp;Conn::LOG  
&nbsp;&nbsp;Notice::POLICY\_LOG  
&nbsp;&nbsp;PacketFilter::LOG

Or, depending on what you want to do, enable "bare mode" with -b,  
which won't load any default scripts.
