NAME ^

Net::BitTorrent::Network::IPFilter - Simple, rule-based IP filter

Description ^

    # Example of a "ipfilter.dat" file
    #
    # All entered IP ranges will be blocked in both directions. Be careful
    # what you enter here. Wrong entries may totally block access to the
    # network.
    #
    # Format:
    # IP-Range , Access Level , Description
    #
    # Access Levels:
    # 127 blocked
    # >=127 permitted

    064.094.089.000 - 064.094.089.255 , 000 , Gator.com

This entry will block the IPs from 064.094.089.000 to 064.094.089.255, i.e. Net::BitTorrent will not connect to any IP in this range.

Warning:

The example above will block any connection to the specified IP-range. This may reduce the number of sources for downloads.

At the moment only one access levels are implemented. A value below 127 means that any connection-attempt is denied.

Notes

Remember...

my $filter = Net::BitTorrent::Network::IPFilter->new( ) ^

This constructs a new, empty object. There are currently no accepted arguments.

$filter->add_rule( $rule ) ^

This method adds a new range to the in-memory ipfilter.

$filter->add_rule( $lower, $upper, $access_level, $description ) ^

This method coerces the arguments into a new range which is the added to the in-memory ipfilter.

$filter->count_rules( ) ^

Returns how many rules are loaded.

$filter->is_empty( ) ^

Returns a boolean value indicating whether or not there are any rules loaded in the ipfilter.

$filter->clear_rules( ) ^

Deletes all rules from the ipfilter.

$filter->load( $path ) ^

Slurps an ipfilter.dat-like file and adds the rules found inside to the ipfilter.

$filter->save( $path ) ^

Stores the in-memory ipfilter to disk.

$filter->is_banned( $ip ) ^

Indicates whether or not $ip is banned. If so, the rule in which it was found is returned. If not, a false value is returned.

IPv6 Support ^

The standard ipfilter.dat only supports IPv4 addresses but Net::BitTorrent's current implementation supports IPv6 as well. Keep this in mind when storing an ipfilter.dat file to disk.
