How come I can't see the Splunk Web interface, though I don't see problems at the port level?

New Member

I have a Search Head Splunk running and I can not see the web interface of this, however when reviewing the settings I can see that the service is running and I do not see problems at port 8000 level. This machine is a Centos 7.

[root@localhost bin]# ./splunk status

Hello @sebastiandelreal,

Are you trying to reach the Splunk web interface from the same system where Splunk is running or from another system?

If you are trying to reach the web UI from another client, check that you can ping the Splunk server:

ping 10.10.9.50

In case you don't know, you can access the web UI via http://10.10.9.50:8000 or http://127.0.0.1:8000 (if Splunk is running on the same system as your web browser).

Also check if iptables is blocking incoming connections:

sudo iptables -L

Hello, Thanks for your Answer

I'm trying to join Splunk from another system.

At the connectivity level, I have an answer when I ping from the system.

This is the result of iptables command:

[root@localhost /]# iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

What is the exact error message in your web browser? Are you getting a timeout?
Your iptables looks fine.
Here are some more ideas:
If you have HTTPS in Splunk enabled, use https://.. instead of http://..
Try it on a different web browser. Perhaps you have a web proxy configured.
If you are running Splunk as root user, you could change the port from 8000 to 80 and see if that helps.
Test the web connection on your Splunk server: curl http://127.0.0.1:8000. It if is working correctly then you should see something like "The resource has moved temporarily
