Hi,

 I am getting Connection refused error, for one of the host. Is it because of firewall issue's? . Please guide me how to go about it? Error log is given below. Please let me know what is the possible solution.

Note: I am connecting splunk from Java(intergrated splunk.jar in my eclipse). For my local server it is connecting. I just need it to query the logs.

I faced the same problem when i was trying to access my Splunk enterprise. In order to make it work, please ensure
1. verify whether you use correct management port (default management port is 8089)
2. If you run on Java 8, need to change SSLSecurityPortocol to TLSv1_2

import these classes:

import com.splunk.HttpService;
import com.splunk.SSLSecurityProtocol;

example

HttpService.setSslSecurityProtocol( SSLSecurityProtocol.TLSv1_2 );
Map connectionArgs = new HashMap();
connectionArgs.put("host", "localhost");
connectionArgs.put("username", "admin");
connectionArgs.put("password", "changeme");
connectionArgs.put("port", 8089);
connectionArgs.put("scheme", "https");
Service service = Service.connect(connectionArgs);

Hi Rohith,
It does seem like a firewall issue. I suggest trying "telnet $hostname $port" from command line on your local machine and check whether you can talk to it or not. Maybe talk to your IT guys to confirm that the port is indeed open for your machine's IP.

Hope this helps.
