============================================================================
RHEL/CentOS 6 does not configure network interfaces on default installation. Also, it is configured to use NetworkManager. To enable networking interface and disable NetworkManager please follow instructions below.
The /etc/sysconfig/network-scripts/ifcfg-eth0 content looks as follows on default installation.
DEVICE="eth0" HWADDR=specifc mac address NM_CONTROLLED="yes" ONBOOT="no"
For DHCP, configure the interface as follows.
DEVICE="eth0" HWADDR=specifc mac address NM_CONTROLLED="no" ONBOOT="yes" BOOTPROTO="dhcp"
Restart the network after configuration. /etc/init.d/network restart
For Static ip, configure it as follows
DEVICE="eth0" HWADDR=specifc mac address NM_CONTROLLED="no" ONBOOT="yes" BOOTPROTO="static" IPADDR=ip address here. NETMASK=netmask here.
Change the /etc/sysconfig/network to have the GATEWAY.
NETWORKING=yes HOSTNAME=www1.nixcraft.in GATEWAY=gateway address here.
Change /etc/resolve.conf
nameserver IP
For example configuration, see Method #3

Restart the network after configuration.
/etc/init.d/network restart
NOTE: In order to edit partition, you must use GUI with 512MB RAM. Duh!!
