For nodes on different subnets, set the netmask so that the nodes can access the subnets in use. Run the following command and answer the prompt to set the netmask:
# ifconfig interface_name netmask netmask
For example:
For the first network interface on the node galaxy:
IP address=192.168.9.1, Broadcast address=192.168.9.255, Netmask=255.255.255.0
For the first network interface on the node nebula:
IP address=192.168.9.2, Broadcast address=192.168.9.255, Netmask=255.255.255.0
For the second network interface on the node galaxy:
IP address=192.168.10.1, Broadcast address=192.168.10.255, Netmask=255.255.255.0
For the second network interface on the node nebula:
IP address=192.168.10.2, Broadcast address=192.168.10.255, Netmask=255.255.255.0
