Splunk receiving indexers receive events from multiple endpoints. Enter details about the Splunk Receiving Indexer here.Splunk deployment servers distribute configurations, applications, and content to groups of Splunk Enterprise instances. Enter details about the Splunk Deployment Server here.You must configure either a Deployment Server or a Receiving Indexer as a minimum to send events to Splunk Enterprise. In the next section you can choose to configure the Deployment Server and Receiving Indexer. If installing the Splunk Universal Forwarder on the Windows Event Collector node, check the Forwarded Events box to send all the forwarded events to Splunk Enterprise.Splunk only needs to see events from that machine, rather than remotely. If installing the Splunk Universal Forwarder on the endpoint, leave the default as Local System.Please follow the instructions to do this. Click Next. You can use an SSL certificate to encrypt the events you send to Splunk.Use the default installation location and click Next.Check the box at the top of the Setup dialog box to accept the license agreement.Double-click the Splunk Universal Forwarder installer.To Install the Splunk Universal Forwarder: You can download the forwarder from Splunk. The Splunk Universal Forwarder can be used to collect data from your endpoints. You can receive events from the Privilege Management Reporting database.įor more information, please see Install the Splunk DB Connect Application. Differences are explained in the installation steps, where applicable. New SSL cert app will then take higher precedence and become your effective configuration.You can install the Splunk Universal Forwarder on your Then, you can use deployment server to push down different app with new SSL certs when the time comes. Because it starts with "zzz" it will be matched as a last resort. ![]() Name your defaults app zzzSystemLocalReplacement. You'll have to be careful with naming them because of settings precedence, but crafted correctly, you can create your own defaults that live in apps and have system/local completely empty. I took advantage of this and created few apps that get copy/pasted alongside the install. If splunk finds nf in one of the apps BEFORE fist launch (hence the importance of LAUNCHSPLUNK=0), it will NOT create system\local\nf. This way, neither your priv key nor cleartext password is ever revealed to whoever runs the installer script. This gives you opportunity to replace cret with your own (known) version and copy/paste your encrypted sslPassword. You'll want to stop splunk from launching with LAUNCHSPLUNK=0 so that system\local\nf isn't generated yet. ![]() My preferred method is to give installer CERTFILE=C:\temp\server.pem with encrypted priv key and omitting CERTPASSWORD entirely. don't provide installer with CERTPASSWORD and swap the encrypted sslPassword in local\nf for your cleartext password (it will be encrypted on next restart).Server.pem will need to have its priv key encrypted with "password" (because reasons) do not provide installer with CERTPASSWORD flag at all.Server.pem needs to have its priv key encrypted with super_secret_pw provide installer with CERTPASSWORD=super_secret_pw.Passwords is where this gets interesting. If they are called server.pem and cacert.pem respectively, they will overwrite the default splunk-generated ones. CERTFILE=C:\temp\server.pem ROOTCACERTFILE=C:\temp\cacert.pem. If your source files are in C:\temp for example, use: msiexec.exe /i splunkforwarder. If you name the files exactly like Splunk does, it will work. I understand this method does not work, as the configuration in $SPLUNK_HOME\etc\system\local\nf will replace any configuration done in the app.Ī) What is the best way to configure Splunk Universal Forwarders to use a self-signed certificate for splunkd during installation?ī) What is the best way to configure Splunk Universal Forwarders to use a self-signed certificate for splunkd after installation? ServerCert = $SPLUNK_HOME\etc\apps\ssl_app\cert\.pem However, after installation, it still uses the default Splunk certificate in $SPLUNK_HOME\etc\system\local\nf.Ģ) Deploy an app containing nf to the deployment clients This method will install Splunk Universal Forwarder, and add the certificate into $SPLUNK_HOME\etc\auth. ![]() I would like to secure splunkd (port 8089) on Splunk Universal Forwarders by using a throwaway self-signed certificate.ġ) Using msiexec to install Splunk Universal Forwarder, and also include the throwaway certificate for the forwarders msiexec.exe /i splunkforwarder-.msi DEPLOYMENT_SERVER=":8089" AGREETOLICENSE=Yes CERTFILE=.pem CERTPASSWORD= /quiet
