       ulogd - netfilter/iptables logging daemon


       ulogd [options]


       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       deprecated ULOG target (which has been superseded by NFLOG) is also supported.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.
