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 192.168.90.0 netmask 255.255.255.0 {
range 192.168.90.200 192.168.90.210;
on commit {
log(hardware);
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
logged:
Jul 6 23:47:18 iserv dhcpd: #001
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.
