ulogd2-json - 2.0.7-1+b1 main

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 JSON support to ulogd. If you install this package, you can
send netfilter logs or accounting data to a log file using JavaScript Object
Notation (JSON).
