output log_unified: filename /var/log/snort/snort.log, limit 128

output alert_acid_db: mysql, database DBNAME server localhost,
sensor_id 1, user DBUSER, password DBPASS

Start Barnyard:
barnyard -c /etc/barnyard.conf -d /var/log/snort -a
/var/log/snort-archive -f snort.log -w /var/log/snort/waldo -s
/etc/snort/sid-msg.map -g /etc/snort/gen-msg.map -p
/etc/snort/classification.config -D

Start Snort with no '-A' and '-b' options. (for example:)
snort -C -d -c /etc/snort/snort.conf -i IF_YOURE_LISTENING_TO -D

Ok, now just relax and wait. 
Next, install BASE to analyse data.

Have fun,
