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.
