NAME

ulogd - netfilter/iptables logging daemon

SYNOPSIS

ulogd [options]

DESCRIPTION

ulogd is a logging daemon that reads event messages coming from the Netfilter 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 The deprecated ULOG target (which has been superseded by NFLOG) is also supported.

The received messages can be logged into files or into a mySQL, sqlite3 or PostgreSQL database. IPFIX and Graphite output are also supported.
