Author [Snort-users] ACID with multiple Sensors?
Bill Warren

2004-09-27, 5:47 pm

All,

I just got ACID, PHP, mysql installed on my Snort box. Then hit it hard
with Nessus to make sure that it works and it does. When I was reading
the results I saw that I could search multiple senors. So, my question
is how do I make multiple Snort boxes talk to each other?

Thanks,
Bill

Bill,

Configure your multiple sensors to all log to the same MYSL database,
each with a different sensor ID or name. I have not done this without
using barnyard. But, in my experience in the past I had to manually
create the additional sensor entries in the sensor table in the MySQL
db, for each of the additional sensors. Things may have changed a
little, so someone may have something to add, as I am no longer using
this method myself. But, it did work in the past with this type of
layout.

7 snort sensors. Each running snort and barnyard. Each instance of
barnyard configured with a unique snort id to reference in the db,
sending alerts to a single mysql DB.

I have snort running on a firewall, I configured 2 instances, on listening on
the internal interface and one on the external, they use different .conf
files so it would be the same as if they were on separate machines. Here is
the mysql line from each:

External:
output database: log,mysql,dbname=snort user=snorter host=192.168.1.2
port=3306 sensor_name=SPARTA_FW_EXT

Internal:
output database: log,mysql,dbname=snort user=snorter host=192.168.1.2
port=3306 sensor_name=SPARTA_FW_INT

As you can see all you have to do is point them at the same database and
assign each one a unique name, with the aptly named sensor_name.
