DHCP Configuration
All machines obtain their IP addresses, names, etc. dynamically for the internal interface. === DHCP Server ===
Make sure that the DHCP server only responds to queries from the internal interface (ETH1).
Modify ''/etc/sysconfig/dhcpd'': {{{

1. Command line options here
   DHCPDARGS=eth1
   }}}

Modifiy ''/etc/dhcpd.conf'' on the head nodde: {{{

Enable DHCP server at boottime {{{
chkconfig dhcpd on
}}}

Start DHCP server {{{
/sbin/service dhcpd start
}}}

=== DHCP Client ===
Modify ''/etc/sysconfig/network-scripts/ifcfg-eth0'' (INTERNAL INTERFACE) on each slave node and the head node: {{{
DEVICE=eth0
BOOTPROTO=dhcp
HWADDR= [add MAC address here]
ONBOOT=yes
TYPE=Ethernet
}}}
