Package: dhcp3-server
Version: 3.1.1-6+lenny4
Severity: normal

I'm trying to write a script that puts all leases assigned by the DHCP server
into a database. My dhcpd config looks like this (minimal example):

ddns-update-style none;
default-lease-time 600;
max-lease-time 7200;

subnet netmask {

  on commit {
    set ip = binary-to-ascii(10, 8, ".", leased-address);
    set mac = binary-to-ascii(16, 8, ":", substring(hardware, 1, 6));
    execute("/root/Martin/dhcp", "commit", ip, "mac", mac);

But when trying to start the DHCP server, I get the following error message:

dhcpd.conf.test line 12: Bogus number mac: digit 22 not in base 16
    execute("/root/Martin.(nobackup)/dhcp", "commit", ip, "mac", mac)
Configuration file errors encountered -- exiting

When I now disable the last 3 commands in the on commit block, dhcpd works, but
apperantly the hardware operator does not return any useful info when it is

This does not fit the description from man dhcp-eval:

> The hardware operator returns a data string whose first element is the type
> of network interface indicated  in  packet  being  considered,  and whose
> subsequent elements are client’s link-layer address.
