splunk UI does not show

h2rr821 — Mon, 16 Jun 2025 21:02:40 GMT

Hello,
We try to see whether splunk can be our solution for dashboard.

I download the trial version which is 9.4.2(I do see the system support for the version 9.4.2 is RHEL8 or RHEL9.)

Is there any other trial version i can download to try? (Our device use RHEL7 and Python 2)

I am able to install the splunk 9.4.2 in our system and run the splunk start

but I cannot access the UI with the address:

http: {domain-name}:8000.

On the page you downloaded the trial version from you should have a button or link to older versions. But be aware that older versions will run out of support sooner than the current one.

Anyway, RHEL7 reached end of normal maintenance over a year ago which means no updates anymore (even security ones).

Splunk doesn't much care about python version in your OS since it brings its own one.

And finally - what do you mean by "I can't access http://my_splunk:8000"? Do you get errors of any kind? What are they? Is your traffic filtered in any way? Can you connect from the Splunk server itself (with curl, for example)? Have you verified that the process is listening on that port? Do you have the port open on your os-level firewall?

Hi @h2rr821

The 9.4.x release you have installed may well work on RHEL7, it is just that it is not supported by Splunk.

You can currently download 9.2.x which is supported until Jan 31 2026 and does support RHEL7. See https://www.splunk.com/en_us/legal/splunk-software-support-policy.html?locale=en_us#:~:text=Splunk%20Enterprise%20/%20Splunk%20Analytics%20for%20Hadoop%20/%20Splunk%20Light* for more info.

Regarding the error, please can you confirm that there is no firewall between you and the Splunk instance, if so is it permitting your requests?

I presume that it is not on the same machine you are working on? Does the system show port 8000 being listened on (e.g. ss -ltn)

As other already said there is probably firewall between your workstation and splunkd running on your RHEL7 box. It could be on RH or if there is any FW between network segments then those are possible candidates.

One way to try it is use ssh tunneling from your workstation to that box (if it's allowed on RH side). Or you could try it with curl on that box to test if it response or not.

Based on your screenshot it should be up and running.

Thank you for your response.

I am able to access it with curl.
curl -v -L http://{domain}}:8000

However I cannot access it from the browsers(I do try multiple browsers).

It said taking too long to respond

The firewall seem no issue:
1. ss -ltn | grep 8000

LISTEN 0 128 :8000 😘

2. netstat -tlnp | grep 8000

tcp 0 0 0.0.0.0:8000 0.0.0.0:* LISTEN 29947/splunkd

Are you curling from the Splunk machine or your endpoint?

The site is taking too long to respond happens in two cases:

1) You're not using a proxy server and the server you're trying to reach doesn't respond to your connection requests - most probably there is something filtering the network traffic between your desktop/laptop and the server.

2) You are using a proxy server and something is filtering the traffic betwen the proxy server and the destination server (or there is no routing between those servers).

Filtering is actually quite probable since you're trying to reach the default 8000 port, which is not a standard http(s) port so it might not be allowed in your organization.

Most probably you'll need to debug it with your network admin.

You can try to verify with tcpdump/wireshark on the splunk server's side whether the initial SYN packet even reaches the server.

I am able to curl it from the splunk machine, but I am not able to do that on my endpoint.

It seems port 8000 port on my endpoint is not allowed in my organization.

This confirms that there are some filtering on network side or even this splunk server. You could check if there is e.g. iptables running with “iptables -vL” command (if I recall right). But as @PickleRick said, more probable there is network level FW between your workstation and splunk server.

In this case your options are: ask help from your network admins and/or try ssh tunneling from your local node to splunk server. But check first that this is allowed in your organization!

I use proxy to work around the port issue.

I get the same thing as the curl command now.

the web ui show nothing, and I inspect it,
"browser-not-supported"? I try multiple browser(Chrome, Edge, Firefox)

I fix it by reset the proxy setting.
I am able to access the web ui.

Thank you very much!!
