Fedora Core 9 DHCP server not handing out reservations.

Posted on 2008-10-06
Last Modified: 2013-12-06
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!

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.

there is a difference:

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

e0 instead of 0e !!
