Setting up DHCP on 2nd NIC

I have a CentOS 5.3 server running Spacewalk (OSS RHEL Satellite Server) v0.4 for handling/monitoring our CentOS environment. The 1st NIC (eth0) is part of the internal network and has a static IP address assigned to it (i.e. 192.168.1.5). I want to utilize the 2nd NIC on the server to be a 'private' DHCP server dedicated just for PXE provisioning needs.

My question is how do I setup a private DHCP server on the 2nd NIC (eth1) and have it assign addresses like 10.1.x.x for PXE bare-metal provisioning needs.

I tried to follow the instructions at the following sites, but it doesn't show how to setup DHCP server on the 2nd NIC only.

NOTE: The internal network already has another DHCP server already active on it, thus needs to remain totally separated from my intended 'private' DHCP network. The 'private' network should be able to see the Spacewalk server but not navigate/access the rest of the internal network.

I think You missing the dhcpd argument to listen only on eth2

[root@dhcserver ~]$ cat /etc/sysconfig/dhcpd
DHCPDARGS=eth1

Made the change and restarted the dhcpd daemon as well to pick it up. Worked like a charm!
