Firewall Documentation

The firewall program is a tool for simplifying and automating the iptables program.

This tool is set to be replaced now that both the firewall and the iptables programs are outdated. The latest iptables program replacement (the nftables program) is superior and the firewall will need major rewrites to utilize the replacement.

This tools is one of the original two programs of the FLL project and is designed to be a fully functional proof of concept for the FLL project.

Standard Parameters

Short	Long	Description
`-h`	`--help`	Print the help message.
`+d`	`++dark`	Output using colors that show up better on dark backgrounds.
`+l`	`++light`	Output using colors that show up better on light backgrounds.
`+n`	`++no_color`	Do not print using color.
`+Q`	`++quiet`	Decrease verbosity, silencing most output.
`+E`	`++error`	Decrease verbosity, using only error output.
`+N`	`++normal`	Set verbosity to normal.
`+V`	`++verbose`	Increase verbosity beyond normal output.
`+D`	`++debug`	Enable debugging, significantly increasing verbosity beyond normal output.
`+v`	`++version`	Print only the version number.

The +Q/++quiet parameter silences all output that is not the intent and purpose of the program. For example, the purpose of the utf8 program is to print the Unicode code point or the UTF-8 byte code. The +Q/++quiet will not suppress this output. The new line printed at the end of the program, is however, not printed. The +Q/++quiet is ideal for using in scripting to help guarantee more consistent and controlled output.

The +N/++no_color simplifies the output to avoid the special color character codes. The special color character codes tend to take up a lot of extra space and may slow down printing performance.
