Description:
PostgreSQL extension to ulogd
ulogd is an advanced netfilter logging daemon. It can act as a replacement for syslog for logging netfilter ruleset violations (via the NFLOG or ULOG iptables targets), can gather per-connection accounting using NFCT, or gather per-rule accounting using NFACCT. Output can be sent to plain text log files, a variety of SQL database formats, XML files, pcap files, syslog, and many other formats. . This module adds PostgreSQL support to ulogd. If you install this package, you can send netfilter logs or accounting data to a PostgreSQL database.
