Querying the dhcp server via php

[Dakkarin]

Hi I wrote a system that keeps track of active directory users and computers with ldap querys however I want to add it a dhcp server query so i can match the ip numbers and usernames .
I searched everywhere but i couldnt find any reasonable solution?
So does anyone know is it possible to query the dhcp server with php?
Thanks

AFAIK, DHCP can only tell you: FQDN of computer, MAC address, IP, date of expiry for IP lease. Nothing about 'usernames'.

Unless you're talking about a WINS server or something, I don't know how you're going to match "IP numbers and usernames" with a DHCP server.

All I want is to learn how to query dhcp server and take mac adressed and related ip adresses

Not me... I have no clue how you'd get PHP to talk to a DHCP server, sorry.
