Hi, I am a beginner in elasticsearch, I installed elasticsearch 6.2.3 and kibana 6.2.3 on a machine (master) centos 6.9 minimal, and I want to access the kibana by another machine windows 7.
1. **machine (master) when elasticsearch and kibana are installed :**
- network configuration (eth0):
- elasticsearch configuration :
> ```
> cluster.name: cluster_hadoop_chu
> node.name: master
> node.master: true
> node.data: false
> path.data: /var/lib/elasticsearch
> path.logs: /var/log/elasticsearch
> bootstrap.system_call_filter: false
> transport.host: localhost
> transport.tcp.port: 9300
> network.host: 0.0.0.0
> http.port: 9200
> discovery.zen.minimum_master_nodes: 3
>
> ```
- Kibana configuration :
> server.host: "192.168.4.101"
> elasticsearch.url: "[http://localhost:9200](http://localhost:9200)"
1. **machine (windows 7) when I want to access to kibana by browser :**
- Network configuration :
- Elasticsearch :
when I type on chrome '[http://192.168.4.101:9200](http://192.168.4.101:9200)' it works fine
- Kibana :
but when i type on chrome '[http://192.168.4.101:5601](http://192.168.4.101:5601)' that's what shows me :
please help me, I searched too much on google and I have not found a solution yet.

I do not understand your config. If you are just starting out with Elasticsearch, I would recommend you start with the default options.
I can see a few potential issues with your config:
- All clusters need at least one data node. The node you are showing has `node.data` set to false.
- You have set `discovery.zen.minimum_master_nodes` to 3, indicating that you expect 4-5 master eligible nodes in the cluster if you have been following [these guidelines](https://www.elastic.co/guide/en/elasticsearch/reference/6.2/modules-node.html#split-brain).
- If you are expecting other nodes, you have not configured [discovery](https://www.elastic.co/guide/en/elasticsearch/reference/6.2/modules-discovery-zen.html) so that you node can find these other nodes.

I have just 1 cluster with 1 node (single node) it's the machine when I installed elasticsearch and kibana but I have centos 6.9 minimal in this machine and I want to access to kibana by browser chrome in the other machine (windows 7)

In that case, you should address Christian's feedback. One way would be to remove the following from the config:
```auto
node.name: master
node.master: true
node.data: false
bootstrap.system_call_filter: false
discovery.zen.minimum_master_nodes: 3
```
