I am trying to set up my forwarders to use SSL without having to use the built in client certs on version 8.0.2.1. It looks like the option useSSL in the outputs.conf file doesn't do what the documentation says.
In https://docs.splunk.com/Documentation/Splunk/8.0.2/Admin/Outputsconf it says
* Whether or not the forwarder uses SSL to connect to the receiver, or relies
on the 'clientCert' setting to be active for SSL connections.
* If set to "true", then the forwarder uses SSL to connect to the receiver.
* Default: legacy
Here is my outputs.conf file
[tcpout]
defaultGroup = default-autolb-group
[tcpout:default-autolb-group]
server = splunkserver:9997
useSSL = true
Here is the inputs.conf file on the server
[splunktcp-ssl://9997]
connection_host = ip
[SSL]
requireClientCert = false
serverCert = $SPLUNK_HOME/etc/auth/servercert.pem
#Use sslPassword = password
sslPassword = password
This outputs.conf file does work
[tcpout]
defaultGroup = default-autolb-group
[tcpout:default-autolb-group]
server = splunkserver:9997
useSSL = true
clientCert = $SPLUNK_HOME/etc/auth/server.pem
sslPassword = password
i am also facing same issue. useSSL is not being honoured, we are getting error "rror encountered for connection from src=<IP>:34818. error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol
