I am trying to set up a DHCP server on my Red Hat linux 8.0 computer, and i just cant get it to work. i installed dhcpd, wrote my configuration file dhcpd.conf, and made dhcpd.leases. my dhcpd file comes out looking like this:

ddns-update-style ad-hoc;
ignore client-updates;
default lease-time 3600;
max lease-time 7200;
option domain-name-servers 207.172.3.8, 207.172.3.9;

subnet 192.168.0.0 netmask 255.255.255.0 {

range 192.168.0.128 192.168.0.255;
option routers 192.168.0.1;
option subnet-mask 255.255.255.0;
}

But every time it try to start dhcpd, it gives me this error:

no subnet delaration for start (0.0.0.0).
**Ignoring requests on start. If this is not
what you want, please write a subnet declaration
in your dhcpd.conf file for the network segment
to which interface start is attached. **

not configured to listen on any interface!

I have eth0 and eth1 on this computer and is acting as a router to my dial up modem. i am trying to configure dhcpd for eth0. I have two Win2k computerson the eth0 network and a FreeBSD computer on the other. I would really aprriciate any help with this, its really got me stumped. Thanks in advance,

Peter

I don't think you can put those declarations outside of the subnet {stuff}

For instance:

And then invoke it with:

/sbin/dhcpd eth0

After the card has been assigned to an IP on that subnet.

you are able to put those declarations out of the subnet stuff, you can post them anywhere in your config file.

option domain-name "x.x";
option domain-name-servers x;
option time-servers x, x;
option netbios-name-servers x;
option netbios-node-type 8;
option lpr-servers xx;
option smtp-server see below;
option pop-server machinename/ip;
option log-servers machinename/ip;

ddns-update-style interim;
ddns-updates on;
ddns-domainname "yourname.here.com";
ddns-rev-domainname "in-addr.arpa";
update-static-leases on;

those are the GLOBAL options for your configuration, and now if you are going to work with pools / groups etc, you can specify
option routers IP.AD.DR.ESS which is quite handy of course if you have 2 gateway machines and you pool is for dhcp client machines which gets a router on your ADSL line for example and the server machines go out through the other gateway over the lease line.. pretty neat uh ?

Range extends into broadcast address (255). try 192.168.0.254

Thanks alot, everything is working now. I tried /etc/dhcpd start instead of /etc/dhcpd start eth0. Thanks for pointing out that i used the broadcast adress. im sure im going to have lots of fun with this. :o)...
