I have installed splunk in local ubuntu and working fine. i got web interface and server started on port 8000. Now i want to install splunk on my live production server. i have installed rpm package successfuly and also started daemon on port 8000. but i cant able to access web interface on internet. is port 8000 not accessible from public ?
There are many things that you can check, but the most common would be firewall issues, this can both be network firewalls or local firewalls (e.g. iptables). You should start by looking at this root to check there is connectivity being allowed.
Also, is it possible to log-on to the WebUI from the server (i.e. locally) to check the service/daemon is working correctly?
