Now im accessing Splunk web using
I would like to access it without entering the port
Can we set this in splunk configuration . Is it possible?
You could configure Splunk to listen on port 80 or 443, but that requires running Splunk as root, which is strongly discouraged.
Your best option probably is to use a proxy or other network device to map port 80 to port 8000.
Sure you can. You just need to change the Splunk Web Port. You can follow one refer to this doc: https://docs.splunk.com/Documentation/Splunk/latest/Admin/Changedefaultvalues#Change_network_ports
