I am setting up the front end for a small cluster using rockscluster, the guides to do this are great but a little light on the network setup.
So having a few issues with networks.
My Front End is a virtual machine running CentOS in Oracle VMBox. Front ends have 2x network cards and I have bridged these to the networks cards on the host. One network card is a wireless wifi card that is connected to my router and the internet beyond. The other network card is ethernet that is connected to a 48 port switch with 32 nodes connected.
OK, in Firefox I can see both the admin menu on my network switch at the heart of my cluster, and I can see my public router admin menu and I can see the internet beyond.
But Rocks doesn't recognize my Front End as a front end and in the terminal I can't seem to ping any of my cluster nodes, even though they are connected via ethernet switch to my front end, also in my terminal I cannot simple things like
yum install net-tools

192.168.1.0 is not my gateway, so not sure why yum is going through that route.
Looks like Rocks has preset this as I am in the middle of a cluster build. But with that in mind, why can't I ping any of my nodes?
Happy to share any screen shots, etc and will be online for a while.
