in thread grep ip address from dhcpd.leases file

Provided you have read permissions for dhcp.leases, just use that file as your data source in the above script:

use strict; use warnings; local $/ = 'lease'; my $leaseFile = '/var/lib/dhcp3/dhcpd.leases'; open my $fh, '<', $leaseFile or die $!; while (<$fh>) { my ($ip) = /\s+(\S+)\s+/ or next; my $client = /client-hostname\s+(".+")/ ? $1 : ''; print "$ip,$client\n"; } close $fh;
