Hi, I have been through many documents on how to get elastic search up and running. I cannot get it to connect when I use the ./elasticsearch command. I am using Ubuntu server 16.04 and the latest version of elastic search from the repository. These are the only settings in my configuration file. I also set the elasticsearch in the service limits.

Something to add in. When I run sudo service elasticsearch status I get: ● elasticsearch.service - LSB: Starts elasticsearch Loaded: loaded (/etc/init.d/elasticsearch; bad; vendor preset: enabled) Active: active (exited) since Thu 2017-03-02 15:39:15 EST; 9s ago Docs: man:systemd-sysv-generator(8) Process: 28953 ExecStop=/etc/init.d/elasticsearch stop (code=exited, status=0/SUCCESS) Process: 28987 ExecStart=/etc/init.d/elasticsearch start (code=exited, status=0/SUCCESS) Mar 02 15:39:15 ELSNETAPPLP1 systemd[1]: Starting LSB: Starts elasticsearch...

Mark, I had it set to publish the actual IP because I was under the impression that was the IP that was being sent out to other clients to connect to. I may be wrong though. ---

Something interesting I have found. With the information put in, I have it listening and responding on IPV6 but not IPV4. Any thoughts on how to get it to IPV4?? ---
