Hello, I have my ES 2.1 only listen on localhost however in my configuration i set `network.bind_host: ["_em1:ipv4_", "_lo:ipv4_", "_docker0:ipv4_"]` and `network.publish_host: _em1:ipv4_` any idea ? ---

I'd use `network.host: _em1:ipv4_` Would that work? ---

The network.host setting is a simple setting to automatically set both network.bind\_host and network.publish\_host to the same host value. If i use network.host: _em1:ipv4_ , my ES 2.1 only listen on em1 iface and i need listening on em1 ,lo and docker0 interfaces ---

In emergency case i use network.host: 0.0.0.0 and my cluster is now listening on all interface but its not a good option ---

I looked at the code and you should be able to set: ```auto network.bind_host: ["_em1:ipv4_", "_lo:ipv4_", "_docker0:ipv4_"] network.publish_host: _em1:ipv4_ ``` Can you change the log level to debug and see what is happening? You should see some lines like: ```auto binding server bootstrap to: XXXXX ``` ---

I setup a VM with ES 2.1 elasticsearch.yml: ```auto network.bind_host: ["_eth0:ipv4_", "_lo:ipv4_"] network.publish_host: _eth0:ipv4_ ``` ```auto [2015-12-09 15:02:31,319][DEBUG][http.netty] [Clea] Bound http to address {127.0.0.1:9200} [2015-12-09 15:02:31,321][DEBUG][http.netty] [Clea] Bound http to address {[::1]:9200} [2015-12-09 15:02:31,322][INFO][http] [Clea] publish_address {192.168.0.18:9200}, bound_addresses {127.0.0.1:9200}, {[::1]:9200} ``` Publish address looks ok but bound addresse failed ---

Just to make sure. Can you try: ```auto network.bind_host: "NONEXSISTINGADDRESS" ``` And then: ```auto network.bind_host: ["NONEXSISTINGADDRESS1", "NONEXSISTINGADDRESS2"] ``` ---

Got it. Actually I tried it and when you set it as an array it's ignored! Opening an issue... See [https://github.com/elastic/elasticsearch/issues/15340](https://github.com/elastic/elasticsearch/issues/15340) ---

So I looked at the wrong code... I was looking at 2.x branch but things changed! Binding to multiple addresses is only supported in coming 2.2 version: [https://github.com/elastic/elasticsearch/pull/13954](https://github.com/elastic/elasticsearch/pull/13954) ---

I've had this issue on Windows Server 2012 R2 and I have workarounded it by setting all 3 parameters to the current machine IP address: ```auto network.host: 192.168.1.100 network.bind_host: 192.168.1.100 network.publish_host: 192.168.1.100 ``` But that disables localhost connections. To allow localhost on some nodes I've set: ```auto network.bind_host: 0.0.0.0 ``` ---

This work for me... But is this correct? ---
