$ cluvfy comp nodecon -n foo, foo1 -verbose Verifying node connectivity Verification of node connectivity was unsuccessful on all the nodes. I can ssh from both nodes to foo, foo1, foo-priv and foo1-priv without being prompted by anything. So I expect the above to work, but it says there was a failure, thank goodness for verbose mode or I probably wouldn't even know that! Any ideas on what to do to trouble shoot this? Thanks, Ethan
