Re: barnyard

[Jason <security () brvenik com>]

-f snort.alert is for input to barnyard. It tells barnyard to look for
snort.alert.[timestamp] for use when reading unified output from snort.

You will then have to have an alert capable output module configured for
barnyard and a unified alert output line for snort to do something with
that data.

EG: in barnyard.conf

output alert_fast

would create classic text files based on alert data.

To completely answer your question we would need to see the
barnyard.conf file and you output directives from snort.conf
