Hello All, I hope some of the rocks users in the list could help me with this problem . A little detailed... beware :) ! I am testing rocks on a two node machine. The master (frontend) installed ok. But when I try to do the compute node (through insert-ethers and selecting ethernet switches) it would go ahead and install the cluster node software but the maste node does not see or pick up the compute node's mac address in the insert appliance dialog box. When the compute node finishes installing, it comes up with a host name and ip address. I thought this was OK, since the compute node does have an IP and a hostname. However, when I try to do tstmachine linux I am getting an error when the script was trying to run the c program "tstfoo." I wrote a c program named tstfoo and placed it in the compute node's /opt.../sbin/ directory. When I launced tstmachines linux again, the c program seem to run but I still got an "expected error frrom compute node using ssh error" Any notes, comments, advice helps.
