# knopmd(8)

separates iptables messages from all other kernel messages.

## NAME

**knopmd** - separates iptables messages from all other kernel messages.

## SYNOPSIS

**knopmd**

## DESCRIPTION

**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.

## SEE ALSO
