The Splunk web interface is not opening (RHEL 7.x server using sudo root access).

[splunking100]

I’ve installed a splunk entreprise (evaluation) in RHEL 7.x server using sudo root access.
But The Splunk web interface is not opening.

Please help.
I tried below options:
a. Export SPLUNK_HOME Path
b. Restarted the splunk services
c. verified : Ports 8000 / 8089 are open

Hi,

As port 8000 seams to be open, had you tried curl command on the server himself, to check if the webserver is responding:
curl http://your.ip.adress:8000
If you get response, the problem is not on splunk install, maybe firewalls anywhere ?

[richgalloway]

Have you checked your firewall(s)?

[abhinav_go]

I am also facing same issue. and got response from curl command.How can i check my firewall(s) if that is not blocking?
