Host machine Configuration

After configuring the two dimmPCI modules, they can now communicate with each other, as well as the outside network. But the outside network cannot access the dimmPCI subnet. Therefore a route to the subnet must be added to redirect packets to the proper device. The most convenient method is to add the route to the gateway for the local network, in this example it is 192.168.10.1. On the machine that acts as the gateway, the following command would be used at the command line

route add –net 192.168.7.0 netmask 255.255.255.0 gw 192.168.10.87

net specifies the subnet that you wish to add the route to and gw is the gateway into the dimmPCI subnet, the eth0 IP address on the system slot NETdimm.

Testing

To test if the configuration was successful and the network was established, execute the following com- mands.

On the host machine:

(this tests the system slot NETdimm configuration)

ping

192.168.10.87

ping

192.168.7.2

(this tests the peripheral slot dimmPCI module configuration)

telnet 192.168.7.2

(this gives you access to the peripheral slot dimmPCI module)

In the telnet session for the peripheral slot dimmPCI module:

(this indicates that the peripheral slot

ping <host machine ip address>

 

dimmPCI module has access to the outside

 

network)
