[Snort-users] My First Snort Oracle Instance

Subject: [Snort-users] My First Snort Oracle Instance
Date: Wed, 30 Mar 2005 18:10:35 -0800
Hi,

Been doing this for a few years, but not with Oracle. Decided to set up the 
next server with an interface to a networked Oracle database, supported by a 
DBA. I may have bitten off too much for something with "experimental" status, 
but this is what I have:

(1) The Oracle v9.2 database was set up using the script provided with Snort, 
Version current, Build 11--which I downloaded and compiled March 11, 2005.

(2) The Oracle v9.2 client was installed on the Snort box. 

(3) All software is installed/compiled on a Red Hat Enterprise Linux AS release 
3 (Taroon Update 2)--Intel(R) Pentium(R) III CPU family, 1266MHz, Intel i686 
box.

(4) Output per snort.config

    output database: alert, oracle, dbname=<-----> user=<-----> password=<----->

(5) Executing the following, snort seems to be running but nothing goes into 
the database. And, other checks shows that snort is seeing a lot of traffic via 
eth0, promiscuous mode.

sudo /usr/local/bin/snort -D -i eth0 -c /usr/local/snort/etc/snort.conf -b -d 
-u root

(6) Toward the end of the syslog I find the following which I have studied in 
the Oracle archives regarding the subject of "fetched column value is NULL" as 
the Oracle versions have evolved.

  database: oracle_error: ORA-01405: fetched column value is NULL  
  query: SELECT MAX(cid)   FROM event  WHERE sid = '1'


I have access to a lot of Oracle support so is there is some coding work I need 
to do to evolve us a bit further than "experimental" on this output, and 
provide feedback? Or, if it is something easy I have not found in the archives, 
or fail to see what is right in front of me, then embarrass me. (-:

Help would be appreciated.

Thank you,
Bob Marcum
