How to resolve "ssl23_get_client_hello unknown protocol" error on indexer and "TcpOutputFd Read error" on forwarder?

Hello guys,

I'm using this on deployment-apps (universal forwarder deployment) :

[tcpout]
defaultGroup = default-autolb-group

[tcpout:default-autolb-group]
server = indexer:9997

[tcpout-server://indexer:9997]
sslCertPath = $SPLUNK_HOME/etc/apps/APP_OUTPUTS_BASE_PPR/local/server.pem
sslPassword = password
sslRootCAPath = $SPLUNK_HOME/etc/apps/APP_OUTPUTS_BASE_PPR/local/cacert.pem
sslVerifyServerCert = false

I'm 99% sure sslPassword for my cacert.pem is not 'password', so isn't it working for server.pem instead (default splunk cert) ?

If I use the correct cacert pass, I get ssl23_get_client_hello unknown protocol on indexer and TcpOutputFd Read error on forwarder.

Thanks for your clarification.

Hi realsplunk,
sorry for this detail:
the steps you have to do are:

  • insert correct password in inputs.conf (verify where is the inputs.conf file where there is sslPassword: $SPLUNK_HOME/etc/system/local) on your indexers;
  • restart indexers, password will be encrypted
  • insert correct password in inputs.conf in your TA (in local directory);
  • restart forwarder, password will be encrypted

If you insert outputs.conf in default directory, password will be encrypted in local directory and not encripted in default directory.
Bye.

So why at http://docs.splunk.com/Documentation/Splunk/6.2.3/Admin/Outputsconf we have :

sslPassword =
The password associated with the CAcert.
The default Splunk CAcert uses the password "password".
There is no default value.*

Thanks a lot!
