``` network.host: some_ip_that_can_be_accessed_from_other_machines ``` `network.host` can not be localhost or 127.0.0.1 if you want to create a cluster (have more than one node) or if you want to be able to access Elasticsearch from another host. ---

Read [this](https://discuss.elastic.co/t/about-the-elasticsearch-category/21) and specifically the "Also be patient" part. It's fine to answer on your own thread after 2 or 3 days (not including weekends) if you don't have an answer. ---

Is the Elasticsearch service running? If the service is running, try this on the machine running Elastic search and from another machine ``` curl http://:9200 ``` That should work from both the Elasticsearch machine and from other machines. If it doesn't work anywhere, check service If it works just on Elasticseach machine - check network, like firewall rules - make sure `` is an IP that can be reached for other machines ---

I probably lack the knowledge. Does discovery.zen.ping.unicast.hosts need to equal the actual network.host names? The current settings provided by komal\_mittal: `discovery.zen.ping.unicast.hosts: ["node1", "node2", "node3", "node4"]` Does it need to be: `discovery.zen.ping.unicast.hosts: ["private-ip_1st-node", "private-ip_2nd-node", "private-ip_3rd-node", "private-ip_4th-node"]` ---

@komal_mittal why do you seek one sole master and one sole data node? Why not start up a two node cluster as per the defaults(master, data, ingest) and have a second data node for replica shards to reside on thus giving you a `green` health status but also redundancy in the event one node goes down. Where does this thread currently stand, what are the issues faced, what has been conducted thus far? ---
