The /etc/sysconfig/network file is used to specify information about the desired network configuration on your server.
           Following is a example /etc/sysconfig/network file:
          
           
           NETWORKING=yes
           FORWARD_IPV4=yes
           HOSTNAME=deep. openna.com
           GATEWAY=0.0.0.0
           GATEWAYDEV=
           
The following values may be used:
           NETWORKING=answer, where answer is yes or no -Configure networking or not to configure networking.
           
           FORWARD_IPV4=answer, where answer is yes or no -Perform IP forwarding or not to perform IP forwarding.
           
           HOSTNAME=hostname, where hostname is the hostname of your server.
           
           GATEWAY=gwip, where gwip is the IP address of the remote network gateway -if available.
           
           GATEWAYDEV=gwdev, where gwdev is the device name eth# you use to access the remote gateway.
           
 
           For compatibility with older software, the /etc/HOSTNAME file should contain the same value as HOSTNAME= hostname above. With the new version of Red Hat Linux 6.2 the FORWARD_IPV4= parameter is now 
           specified in the /etc/sysctl.conf file instead of the /etc/sysconfig/network file.
