Re: Sguil DB table names

[Y M <snort () outlook com>]

Thanks Doug.
Yes I am using MySQL 5.5 and no, I haven't seen this one before. Really appreciate the reference. I will give it a try.
I am checking Security Onion, but I want to get my hands dirty first :).
Thanks again.YM

Hi Y M,
Are you using MySQL 5.5?
Have you seen this?http://marc.info/?l=sguil-devel&m=131291794011285

You can also take a look at Security Onion if you'd like something to refer to. 
Hope that helps!

Thanks,Doug

Subject: [Snort-users] Sguil DB table names










This is not strictly a Snort question, it is more related to Sguil and hoping that someone may have insight into this.
I have a Sguil sensor setup to only use the snort_agent. My understanding of Sguil is that as soon as a sensor reports 
an alert to the server for the first time, it will create the event, data, icmphdr, iphdr, tcphdr, and udphdr tables 
into the Sguil DB on the server.

That said, my setup does create the tables, however, it appends the sensor name and a date stamp to table names. For 
example, my sensor name is "ids-test" and the date is 12 May 2013. In this case, the tables created will have the 
following naming convention: tablename_sensorname_datestamp --> event_ids-test_20130512. This happens to all tables 
that get created.

This results in the following error:ERROR: sguil: Expected confirm 1 and got: Failed to insert 1: mysqlexec/db server: 
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right 
syntax to use near 'TYPE=MERGE UNION=('event_ids-test_20130512')' at line 1

If I rename the tables to the proper names, and run Sguil again, I get the following error:
ERROR: sguil: Expected confirm 1 and got: Failed to insert 1: mysqlexec/db server: Table 
'sguildb.event_ids-test_20130512' does not exist.

If I drop the created tables and run the process, the same error (first one) occurs again.

Am I missing something in the configurations (Barnyard2 or snort_agent.conf) or the entire setup?

ThanksYM
