I am able to do ssh and password less connection all setup looks fine.

I don't unsderstand whats going on as ambari server is up and amabari agent is up. i think something is related to network and port. I see below things while do netstat -anp

It is something to do with ipv4 and ipv6. instance have ubuntu (gcc version 4.8.4 (Ubuntu 4.8.4-2ubuntu1~14.04.3)).
