Exposing 'transport.tcp.port' to outside world

Elastic Stack Elasticsearch
1

In elasticsearch.yml file of version 5.5.0, I have below:

http.port: 1180
transport.tcp.port: 1183

Then I went through various Elasticsearch documentation (this and this) and able to expose port 1180 to outside world by configuring below two:

network.host: 127.0.0.1
http.host: 0.0.0.0

Problem: I am not able to expose port 1183 to outside world (it's only accessible inside localhost). Tried below:

transport.publish_port: 1183

Please guide.

Could you share your logs please?

Use

```

```

To format your code instead of

Thanks

Please use the right format for code. PREFORMATTED TEXT and not BLOCKQUOTE.

Thanks.

So 0.0.0.0:1180 is the REST layer accessible from another workstation.
But as you defined network.host: 127.0.0.1, Transport layer is only available from localhost 127.0.0.1:1183.

If you want to make both transport and http accessible from outside, do this:

network.host: 0.0.0.0
http.port: 1180
transport.tcp.port: 1183

Configuration network.host: 0.0.0.0 doesn't work as it throws:

I have tried setting below to true and false, no luck:
bootstrap.system_call_filter: true

Can you please help further?

You need to fix the 3 problems you have here:

[2017-09-29T09:01:19,614][INFO ][o.e.b.BootstrapChecks    ] [node2] bound or publishing to a non-loopback or non-link-local address, enforcing bootstrap checks
ERROR: [3] **bootstrap checks failed**
...

Sadly you did not share the full logs so I can't help.

But please read https://www.elastic.co/guide/en/elasticsearch/reference/current/bootstrap-checks.html

That should help.
