NAME

tableutil — converts and performs operations on tables

SYNOPSIS

DESCRIPTION

tableutil can be used to convert files with IP-addresses and ranges and aggregate networks. The options are as follows:

-c commands

execute the commands specified by commands.

-f file

file is the name of the file with commands to be loaded.

-q type [file]

Quick-convert file from type to a CIDR-notation, as used by PF. type can be either 'text' or 'p2b'. The text format accepts addresses on the form 'n.n.n.n', 'n.n.n.n-n.n.n.n' or 'n.n.n.n/n'. p2b is the format used in the lists provided by blocklist.org. If file is omitted, standard input is assumed. p2b-files can be either gzipped or uncompressed.

COMMAND FILE/STRING

The command file/string consists of a series of statements separated by ;

EXAMPLES

Example quick-conversion:

	$ tableutil -q p2b ads.p2b.gz

Example command-file:

	# Assign some values to some variables
	$range = { 192.168.0.0-192.168.2.255 };
	$cidr = { 192.168.3.0/24 };
	$text = load(text, "file_with_networks");
	$p2b = load(p2b, "ads.p2b.gz");

	# Do some calculations and store them in some other variables
	$table1 = difference($p2b, $text);
	$table2 = union($range, $cidr);
	$table3 = invert( { 192.168.0.1 } );
	$table4 = intersect( { 192.168.1.0-192.168.3.255 }, $range);

	# Save some of the variables, and a bonus, to files.
	save(cidr, "table1", $table1);
	save(range, "table2", $table2);
	save(cidr, "table3", $table3);
	save(cidr, "table4", $table4);
	save(range, "table5", { 0.0.0.0/0 } );
	save(single, "table6", $cidr );

RETURN VALUES

tableutil can exit with the following values:

0 Command completed successfully.

 

1 Invalid arguments supplied.

 

-1 Internal error.

 

BUGS

Many, probably. And the man-page needs improving.
