NAME

NET::IPFilter - Perl extension for Accessing eMule / Bittorrent IPFilter.dat Files and checking a given IP against this ipfilter.dat IP Range. IT uses conversion from IP to long integers in Perl and afterwards compairing these long integer ranges against the calculated number of the given IP

Warning: Please Update your Sources. Current Version fixed a very critical bug that prevents Program from working correctly.

SYNOPSIS

  use NET::IPFilter;

 my $ipfilter = '/home/user/files/ipfilter.dat';
 my $IP = "3.3.19.81"; # :)

 my $obj = NET::IPFilter->new(	ipfilter	=> $ipfilter,
				tmpdir		=> '/var/tmp',
				force_init	=> '0'
);

 my $isValid 	= $obj->isValid($IP);	#  1 not to be blocked | 0 to be blocked
print $isValid;

DESCRIPTION

my $obj = NET::IPFilter->new( ipfilter => $ipfilter, tmpdir => '/var/tmp', force_init => '0' );

ipfilter can be an absolute file in the filesystem or an uri. the uri filename can be a normal textfile or a gzip compressed file

tmpdir classifies a folder where to store some temporary files

force_init can be 0 or 1 where 1 means that all files are downloaded again ( if uri is an http-link )

This current version is intended to be used on Linux/Unix OS System. My new Version NET::IPFilterSimple will be usable for both Linux/Unix and Windows. As i have no solaris or MAC i dont know how to fix the module to bring it to life on that mashines

Currently i am going to release a module NET::IPFilterSimple that i hope is some ms faster than NET::IPFilter
