Hello, excuse me, my english is terrible; we are building a cluster with 3 PCs: RedHat 9 (kernel 2.4.20-8) like OS and OSCAR 2.3.1.

After follow the installation steps we try to network boot the nodes... and i think we have a problem with the DCHP:

(...)
No DHCPOFFERS received
No working leases in persistent database
(...)

Yes, i've read the FAQ... the dhcp server is runnig in the server...
Clients fail to boot or get IP address
http://oscar.sourceforge.net/faq/show.php?version=1.2.1&key=dhcp-not-running
Client nodes fail network boot
http://oscar.sourceforge.net/faq/show.php?version=1.2.1&key=net-boot-fail

Our dhcp.conf file:

deny unknown-clients;
option subnet-mask 255.255.248.0;
option broadcast-address 150.244.87.255;
option domain-name "";
option routers 150.244.80.198;
ddns-update-style none; # For dhpcd version 3

# Defined cluster nodes...
subnet 150.244.80.0 netmask 255.255.248.0 {
        group {
                host oscarnode1{
                        hardware ethernet 00:01:80:36:bf:c9;
                        fixed-address 150.244.80.199;
                        filename "pxelinux.0";
                        option routers 150.244.80.198;
                        option domain-name "oscardomain";
                }
                host oscarnode2{
                        hardware ethernet 00:01:80:32:9b:1d;
                        fixed-address 150.244.80.200;
                        filename "pxelinux.0";
                        option routers 150.244.80.198;
                        option domain-name "oscardomain";
                }
        }
}

We are using in the 3 PCs Realtek RTL8100BL LAN chips...

Could you help me? Thank you in advanced!!!
