ERROR TcpInputProc - Message rejected. Received unexpected 1009858864

Hello,

problem on splunk enterprise 6.4.2

I've just set up an intermediate (heavy) splunk 6.4 forwarder between my syslog-ng server and my indexer. This heavy forwarder is supposed to help me filtering F5 BigIP logs

1 - Receiving was set up on Indexer to listen on port 5141 (not 9997 default port) usin web Gui (then i double check that the stanza is ok in inputs.conf)

2 - Forwarding was activated from forwarder using web Gui (menu "Forwarding ans Receiving / Forward data") adding "xxx.xxx.xxx.xxx:5141" where xxx.xxx.xxx.xxx is the IP of my indexer

3 - log Stream can be displayed on idexer using tcpdump

4 - no data is collected in any index and the error " ERROR TcpInputProc - Message rejected. Received unexpected 1009858864" is thrown

What could be wrong ?

just one dumb thing I forgot to mention : I used to think It was possible to grab the Syslog stream of my device in my Forwarder directly through TCP receiver of my Forwarder (see the screenshot)

It ended up being a misconfiguration -

yes clearly a misunderstanding (in my case) of how heavy (intermediate) forwarders should deal with their input data

Hi Laurent,

The fwd (whatever version) can receive syslog streams, as any other fwd.
keep in mind that if you do not need any functions from the Heavy fwd (web interface, advanced filtering), you should use the Universal fwd (even to act as a relay).

yeap ! Understood ! But receiving must be set from "Data inputs » UDP " and not "Forwarding and receiving » Receive data » Add new " (my mistake) 🙂
