PROGRAM:
NAME
mason - interactively create a firewall
SYNOPSIS
mason < logfile > rulefile
DESCRIPTION
This manual page briefly documents the mason command.
mason interactively generates a set of firewall rules for a Linux-based firewall. This is
done by turning on full IP logging, watching the logs for connections, and generating
rules describing the connections seen. mason is familiar with most of the quirks of
various connection types (such as ftp and IRC), and can output rules for 2.0.x ipfwadm,
2.2.x ipchains, and Cisco packet filters.
mason operates by reading in log file information from standard input and writing firewall
rules to standard output. This allows mason to work offline or on a separate system.
Real-time firewall generation can be achieved with a command like tail(1).
Most users will want to run mason with a user-friendly interface such as
mason-gui-text(1).
