| The second way is to be lucky (or well-off) and have a second interface on each compute node which you can connect to the outside world (or switch). Even so, this is not straightforward. Note that the second interface of a rocks compute node is not installed by default. In the below the interface is assumed to be prefixed with //em// (instead of //eth//), and we assume we are adding an interface on //compute-0-0//. Apply your case accordingly. | The second way is to be lucky (or well-off) and have a second interface on each compute node which you can connect to the outside world (or switch).

| - To install the public interface run ''rocks add host interface compute-0-0 em2 ip=10.1.2.110 mac=F0:1F:AF:D0:9F:D4 subnet=public'' with the appropriate IP and MAC address. Note that the //subnet// field specifies the network you want to connect to (found from Step 1 above). | - To install the public interface run ''rocks add host interface compute-0-0 em2 ip=10.1.2.110 mac=F2:BB:CB:D3:1F:C4 subnet=public'' with the appropriate IP and MAC address.
