NAME

Text::DHCPLeases - Parse DHCP leases file from ISC dhcpd.

SYNOPSIS

    use Text::DHCPLeases;

    my $leases = Text::DHCPLeases->new("/etc/dhcpd.leases");

    foreach my $obj ( $leases->get_objects ){
        print $obj->name;
        if ( $obj->binding_state eq 'active' ){
           ...
    }
    ...

DESCRIPTION

This module provides an object-oriented interface to ISC DHCPD leases files. The goal is to objectify all declarations, as defined by the ISC dhcpd package man pages.

This interface is useful for analyzing, reporting, converting lease files, or as a tool for other applications that need to import dhcpd lease data structures.

CLASS METHODS

new - Class Constructor

  Arguments:
    Hash with the following keys:
    file  -  Leases file path
  Returns:
    Text::DHCPLeases object
  Examples:
    Text::DHCPLeases->new(file=>"/etc/dhcpd.leases");

INSTANCE METHODS

get_objects - Get objects from leases file

  Arguments:
    Object attributes to match (optional)
  Returns:
    Array of Text::DHCPLeases::Lease objects, 
    or iterator depending on context.  
  Examples:
    my $it = $leases->get_objects(ip_address=>'192.168.0.1');
    while ( my $obj = $it->next ) ...

print - Print all lease objects contents as a formatted string

  Arguments:
    None
  Returns:
    Formatted String
  Examples:
    print $leases->print;

BUGS AND LIMITATIONS

Correct parsing of leases files depends on changes made to the format of said files by the authors of the ISC DHCPD package. This module was tested against leases files generated by ISC DHCPD version 3.1.0. In addition, I do not have access to leases file with all possible declarations and statements, so parsing could be broken in some circumstances. Patches are welcome.

No bugs have been reported.

Please report any bugs or feature requests to "bug-Text-DHCPleases@rt.cpan.org", or through the web interface at <http://rt.cpan.org>.
