NIC IP Aliases

I needed to and Aliases for some IP addresses to the ethernet card on the Rocks Cluster to allow individual nodes to have their own public IP addresses.
I created a copy of the /etc/sysconfig/network-scripts/ifcfg-eth0 to ifcfg-eth0:0. This new file was edited with vi to contain

DEVICE=eth0:0
HWADDR=xx:xx:xx:xx:xx:xx
IPADDR=xxx.xxx.xxx.xx
NETMASK=255.255.255.0
BOOTPROTO=static
ONBOOT=yes


/sbin/service network restart to update the changes made.

/sbin/ifconfig shows the new configuration.

The change was tested by connecting the node switch to the public 211 subnet and the ip address could be pinged from the subnet showing that the changes were working.
