NAME
ulogd - netfilter/iptables logging daemon
SYNOPSIS
ulogd [options]
DESCRIPTION
ulogd is a logging daemon that reads event messages coming from the Net-
filter connection tracking, the Netfilter packet logging subsystem and
from the Netfilter accounting subsystem. You have to enable support for
connection tracking event delivery; ctnetlink and the NFLOG target in
your Linux kernel 2.6.x or load their respective modules. The deprecated

or PostgreSQL database. IPFIX and Graphite output are also supported.
