knopmd - separates iptables messages from all other kernel messages.
knopmd reads messages from the /var/lib/fwknop/fwknopfifo named pipe
and prints any firewall related log messages to the fwknop data file
"/var/log/fwknop/fwdata". Note that knopmd is only used in the legacy
port knocking mode, and the default authentication/authorization method
used by fwknop is Single Packet Authorization (SPA). fwknop cannot
detect port knocking sequences without knopmd running on the machine.
knopmd references the fwknop.conf configuration file which by default
is located at /etc/fwknop/fwknop.conf, but a different path can be
specified on the command line.
