Dear Dan,
I have attached my ossec.conf file. Yes for the first problem
I have known where the settings for the /var/www/log/access_log and
error_log. For your next question I am not sure how you determine the rook
check? I am using Centos 6.5 (Final). Also how to determine if the active
response is being use? Should I comment it to off it?
Regards,
Frwa.
