Anyone out there able to tell me what I'm doing wrong here?  Trying to setup ISC's DHCPd 2.0pl5 on RedHat 7.0.  Setup with just a simple subnet as follows:
subnet 192.168.1.0 netmask 255.255.255.0 {
  range 192.168.1.50 192.168.1.70; }

When I start dhcpd, I get the following error:
Can't bind to dhcp address: Address already in use exiting.

The ip address of the machine this is running on is 192.168.1.109, and I have added a route to 255.255.255.255 through eth0
