How to disable Splunk Web on a universal forwarder?

New Member

I use Nessus to scan for SSL issues, and the Splunk Web interface is being flagged due to the self signed certs. I have managed to make my indexer / search head use internally MS CA certs and go the cert chain sorted for the login screen to Splunk Web. My question is, do I use a similar process for the forwarders, or can I shut down the web interface on the Universal forwarder? If so, how? If not, how do I change the certs on the UF?

If the Nessus detection is on port 8089, you can shut it down by adding this to UF's server.conf:

[httpServer]
disableDefaultPort = true

Note: This is NOT disabling SplunkWeb. A UF does not have SplunkWeb ever at all, period. This is disabling the REST API server. This has side effects on the UF, such that the CLI largely (but not completely) quite working. See Matt's .conf talk:
