Troubleshooting

If there is only one subnet declaration, and no network interfaces are in the range of that subnet, the DHCP daemon fails to start, and an error such as the following is logged to /var/log/messages:

    dhcpd: No subnet declaration for eth0 (0.0.0.0).
    dhcpd: ** Ignoring requests on eth0.  If this is not what
    dhcpd:    you want, please write a subnet declaration
    dhcpd:    in your dhcpd.conf file for the network segment
    dhcpd:    to which interface eth1 is attached. **
    dhcpd:
    dhcpd:
    dhcpd: Not configured to listen on any interfaces!
