Reservations only, without a range?

[Baird, Josh]

Hi,

I'm trying to setup a scope that only offers leases to those hosts who have reservations defined.  Therefore, I do not want to specify a "range," as I do not want dhcpd to hand out any leases who don't have reservations.  However, I am getting the "no free leases" error in my logs:

May 29 10:03:42 fc-wrform01 dhcpd: DHCPDISCOVER from 00:50:56:a5:00:1b via eth0: network 172.26.100.0/22: no free leases

May 29 10:03:44 fc-wrform01 dhcpd: DHCPREQUEST for 172.26.100.253 (172.26.101.230) from 00:50:56:a5:00:1b via eth0: unknown lease 172.26.100.253.

My configuration is as follows:

--

ddns-update-style interim;
omapi-port 7911;
deny unknown-clients;
ignore client-updates;
authoritative;
allow booting;
allow bootp;

subnet 172.26.100.0 netmask 255.255.252.0 {
  option routers      172.26.100.1;
  option subnet-mask  255.255.252.0;
  option domain-name    "corp.com";
  option domain-name-servers  172.26.137.135;
  option log-servers    syslog;
  option ntp-servers    ntp;
  default-lease-time 21600;
  max-lease-time 43200;

}

host buildtest8.corp.com {
  dynamic;
  hardware ethernet 00:50:56:a5:00:1a;
  fixed-address 172.26.100.252;
        supersede server.filename = "pxelinux.0";
        supersede server.next-server = ac:1a:65:f2;
        supersede host-name = "buildtest8.corp.com";
}

Is this type of configuration possible?

Thanks,

Josh
