Subject Re: specify the IP address of the master node
Date Thu, 11 Nov 2010 18:27:16 GMT
How are the internal IP addresses set up?  If all three nodes have their
internal IP addresses in the same subnet then you can set a route on the two
private-only nodes.

So for instance:

Node 1 eth0: 192.168.0.1/24
Node 1 eth1: 128.220.233.214/24

Node 2 eth0: 192.168.0.2/24

Node 3 eth0: 192.168.0.3/24

If you have an IP setup like that then you can run on node 2 and node 3:
route add -host 128.220.233.214 gw 192.168.0.1
