Splunk server.conf4/13/2023 It’s a 0 byte license that enables the Enterprise features. Splunk Support will usually give you a “Deployment Server License” file. So, if you have a Deployment Server that is also a License Slave, then you’ll have to use the same pass4SymmKey all around. There’s two quick caveats right out of the box.įirst, the Deployment Client -> Deployment Server pass4SymmKey and the License Slave -> License Master pass4SymmKey are set using the same setting.

The Splunk nf file- has a pass4SymmKey option that can be set in a few different stanzas, so you can use a different value for different modes of communication. But, in my experience, the use of pass4SymmKey related to Deployment Server is rare. The pass4SymmKey comes up frequently in conversations about License Masters, Cluster Masters, and Search Head Clustering. As a reminder, pass4SymmKey is a symmetric secret shared between two Splunk nodes to authenticate system-to-system REST API usage. The advice here is to use pass4SymmKey in order to secure Deployment Client to Deployment Server. That’s where we will focus our efforts today. I’ve highlighted the “Deployment server to deployment clients” part. Here’s a screen cap from that page taken today (late July 2018): ![]() Let’s start at the docs, in the Securing Splunk Enterprise manual.
