Prelude PFlogger is an OpenBSD PF sensor for
Prelude-IDS, a distributed, hybrid IDS. Prelude
PFlogger simply listens on the pflog0 virtual
network interface (which is where PF redirects
logged packets), and it sends alerts to the
Prelude Manager. Prelude PFlogger does not need
pflogd in order to work, and both Prelude PFlogger
and pflogd can run on the same host.
