Fedora Core 9 DHCP server not handing out reservations.

I have a Fedora Core 9 server running as a DHCP and DNS server. There are many reservations, but one DHCP client will not pick up the correct IP. However, it does obtain an IP from the specified pool. I have verified the MAC and the other options specified. I've also deleted and recreated the reservation (via webmin & dhcpd.conf), stopped and restarted the server. The syslog doesn't show anything out of the ordinary. I'm @ a loss!

Hi,

maybe the client is sending the DHCP request with an "unexpected" MAC address? Does it have one or two network interfaces?

Thanks for the prompt response!

It has serveral network interfaces... it's telecom equipment with a linux CLI. But the syslog shows the DHCPDISCOVER, OFFER, etc..coming from the correct MAC.

Here's the pertinent information regarding the problem client below. Please note, there's no there issues with other reservations.

dhcpd.conf:
host host-4.60
      {
       hardware ethernet 00:e0:0c:00:00:60;
       next-server 10.11.12.5;
       filename "filename";
       fixed-address 192.168.4.60;
       option subnet-mask 255.255.240.0;
       option root-path "/bootpath";
      }
Syslog:
Oct  6 15:38:49 servername dhcpd: DHCPDISCOVER from 00:0e:0c:00:00:60 via eth0
Oct  6 15:38:50 servername dhcpd: DHCPOFFER on 192.168.8.242 to 00:0e:0c:00:00:60 via eth0
Oct  6 15:38:50 servername dhcpd: DHCPREQUEST for 192.168.8.242 (192.168.1.24) from            00:0e:0c:00:00:60 via eth0
Oct  6 15:38:50 servername dhcpd: DHCPACK on 192.168.8.242 to 00:0e:0c:00:00:60 via
eth0

Hi,

there is a difference:

config file: 00:e0:0c:00:00:60
syslog: 00:0e:0c:00:00:60

e0 instead of 0e !!

Regards
Kurt
