Using snort 1.9.0 build 209 on a slackware 8.1 linux.

Starting snort with: ./bin/snort -g snort -u snort -o -t /usr/snorteth0 -c
./ect/snort.conf -p -i eth0



From my snort.conf:



include ../rules/classification.config

include ../rules/reference.config

As you can see, I user the "alert" facility into the database ruletype
declaration.

The problem Is that snort continue to log preprocessor alerts into the
/var/log/snort/alerts file!!!!



I've realized that also rules declared with ruleaction "alert" are logged
into the file and not in the Database. I think is better to create a
ruletype called "alert" to log all of these into the dataset but, alert
ruletype I always  already declared!



How to solve these problems ??
