How Can I configure for another ES cluster?

I am trying to use the data from another totally different ES cluster through Kibana.
I already changed Kibana URL in its yml. For ES, how should I configure it to not go to the default 127.0.01?

Below is my current ES yml with new port/host. What else shall I do to make it listen to new port/host?

---------------------------------- Network -----------------------------------

Set the bind address to a specific IP (IPv4 or IPv6):

network.host: 192.168.0.194

Set a custom port for HTTP:

http.port: 9300

For more information, see the documentation at:

http://www.elastic.co/guide/en/elasticsearch/reference/current/modules-network.html

--------------------------------- Discovery ----------------------------------

Pass an initial list of hosts to perform discovery when new node is started:

The default list of hosts is ["192.168.0.194"]

discovery.zen.ping.unicast.hosts: ["192.168.0.238","192.168.0.237","192.168.0.208","192.168.0.181"]

You already have;

I keep see below error:

Exception in thread "main" BindTransportException[Failed to bind to [9300-9400]]; nested: ChannelException[Failed to bind to: /192.168.0.194:9400]; nested: BindException[Can't assign requested address];

Why did you change this? You should leave it at 9200.

Changed it back to 9200 but still the same error...

Does that address exist on the host?

I retrieved from below when i do: curl {server address}/_nodes/_local.
I can choose any address from unicast, right?

Are those IPs bound to the host you are trying to start ES on?

right.
The server address there (I curled with) is the new ES server i try to get on.

Could it be the ES server is already on so it prevents duplicate start?
