In our departement we have a blade system with one master node and four slave nodes that are connected to the master node. The system uses its own subnet (192.168.1.x) and only the master node is connected to the intranet (and thereby to the internet). On every node runs CentOS 5. I would like to update CentOS (by using yum). How to update the slave nodes as they don't have direct access to the intranet/internet. Could you please lead me in the right direction how to setup a forwarding/routing so that the slave nodes can do requests to the intranet/internet, too?
More details about the setup:
- master node
- 4 slave nodes
Connected to master eth0
IPs 192.168.1.1-4 (fetched using DHCP running on master)
Only 220.127.116.11 (=master) is allowed to access the internet (by using a proxy).
