dhcpd3 no free leases

Hey guys,

For some strange reason my DHCP server no longer allocates IP addresses.

I've deleted /var/lib/dhcp3/dhcpd.leases and /var/lib/dhcp3/dhcpd.leases~ and /var/lib/dhcp3/dhclient.eth0.leases
Which by the way, had many old dhcp entries in them (From months back, which should have expired).

I restarted dhcpd3 and got the machine to request another IP address.

dhcpd3 still reports:
Jan 14 15:02:40 dhcpserver dhcpd: DHCPDISCOVER from 11:22:33:44:55:66 via eth0: network 10/8: no free leases

Sooo.... I have 2 questions...

How can I fix this, and how can I prevent it from happening again?

Did you change anything in your dhcpd config file? What distro are you using, btw? Did you compile dhcpd3 from source, or are you using a version provided by your distro? Do you have multiple NICs?

Hey Atreyu,

Yes, I have, here's my DHCPd config file (With exampled quotes removed):

I'm using Ubuntu Server 11.04.

I'm using the standard one. Yup. I have 2 NICs & one Virtual one.
eth0: 10.0.0.1 (Statically assigned from DHCP server)
eth1: 12.0.0.2 (Static, not controlled by DHCP, virtual one for interfacing with the ADSL card)
ppp0: (Dynamic from ISP, this is an ADSL 2 card using Bridged Ethernet).
