Using RedHat AS Enterprise edition I copied out the recommended dchpd.conf file (from the RHFedora + Enterprise Linux Bible by C. Negus) with my own adaptions - very little.

When I used the command line "service dhcpd start" I got the following message:
Not configured to listen on any interfaces!

Here is my entire dhcpd.conf file:

ddns-update-style interim;
ignore client-updates;

subnet 10.0.0.0 netmask 255.255.255.0 {

option routers 10.0.0.1;
option domain-name-servers 10.0.0.1;
option subnet-mask 255.255.255.0;
option domain-name "itec240.com";
range dynamic-bootp 10.0.0.150 10.0.0.225;
default-lease-time 21600;
max-lease-time 43200;

#set name server to appear at a fixed address

host ns {
next-server ns1.itec240.com;
hardware ethernet 00:0D:87:09:E8:B9;
fixed-address 10.0.0.1;
}
}

Yes, I know using 10.0.0.1 isn't the best choice - but that is what the text gives - and it enables me to be sure it doesn't interfere with the settings of the router I usually use.

So how can I configure it to work on an interface?

i quick thought is that you have not defined any range's.

I had same issue when i went with dual nic's on a server, and for some reason, adding an empty scope on the second nic made this problem go away.

Ill post my dhcpd.conf file shortly

# dhcpd.conf

ddns-update-style ad-hoc;
# options common to all subnets
option domain-name "domain.com";
# name servers
option domain-name-servers x.x.x.x;

max-lease-time 7200;

#
# configuration for 10 subnet
subnet x.x.10.0 netmask 255.255.255.0{
range x.x.10.74 x.x.10.150;
option routers x.x.10.254;
option broadcast-address x.x.10.255;
}
subnet x.x.214.0 netmask 255.255.255.0{
}



Once I added the last 2 lines, my error went away and th 10.x subnet got IP's. I had 2 nics on 2 subnets.

One possibility is the /etc/sysconfig/dhcpd file does not contain any command line arguments. This sets the interface.

DHCPDARGS=eth0

Thanks for the suggestions debianmike and michaelk. There wasn't any designation in the /etc/sysconfig/dhcpd file so I put in the eth0 info BUT that didn't solve the problem. Didn't restart the computer to see if that made any difference - but don't have access to it now to try it - will do later. Nor did adding the new subnet line help - couldn't get the syntax to work.

Did you restart the server?

Finally got it working but not sure how - a bit annoying. I configured a client on the network with Primary address of 10.10.10.2 and secondary address of 10.10.10.1. This seemed to spark the error report request for a submask for eth0 (10.10.10.1) when I tried to start the server. I put it in and then the server started. However, the other computer I tried on the network failed to activate the eth0 device on it when I changed it's settings to get an IP address from dhcp - so the server may be running but it isn't functioning as a dhcp server yet!

Back to the texts ...

Thanks

dhcpd gives that error when no ip address is bound to the INTERFACE= specified in /etc/default/isc-dhcp-server
