Rules

Configuration

Rulesets are chosen during setup and are specified in /etc/nsm/pulledpork/pulledpork.conf.
If you change the the configuration in pulledpork.conf, then you will need to run rule-update (if in a server/sensor deployment, run rule-update on the master first, then the sensor, or wait for it to be replicated).
