ERROR TcpInputProc - Received unrecognized signature POST / HTTP/1.1

Hi,
I configured Splunk to receive tcp request on port 9000. I configured as well props.conf to parse xml file:

[wsdmxml]

KV_MODE = xml

LINE_BREAKER = ([\r\n]+)(?=####<)

SHOULD_LINEMERGE = false

BREAK_ONLY_BEFORE = ^<wsnt:Message\s+\w+

MUST_BREAK_AFTER = wsnt:Message>

TRUNCATE = 9999999

LINE_BREAKER_LOOKBEHIND = 10000

MAX_EVENTS = 1000000

and inputs.conf

[tcp://:9000]

disabled = 0

connection_host = ip

sourcetype = wsdmxml

source = tcp:9000

but I'm still receiving TcpInputProc - Received unrecognized signature POST / HTTP/1.1 error.

<soap:Envelope xmlns:mows="http://docs.oasis-open.org/wsdm/mows-2.xsd" xmlns:mowse="http://docs.oasis-open.org/wsdm/mowse-2.xml" xmlns:muws1="http://docs.oasis-open.org/wsdm/muws1-2.xsd" xmlns:muws2="http://docs.oasis-open.org/ws▒▒▒

SOAPAction:

My server is set up to forward the request to http://splunkserver:9000.
What I'm doing wrong?

Two problems. First, you have set up a Splunk TCP listening port, which only accepts connections and data directly from a Splunk Forwarder. Second, even if you use a standard TCP listening port, I suspect you don't really want the exact contents of a POST request, but only the (decoded) payload. The TCP listen ports are not HTTP server ports, so you will receive all headers and other content, and if your SOAP request is expecting any kind of response or connection close, it is not going to get it.

Is there a way to user REST API to retrieve data from HTTP request into Splunk? What is the proper way to get data over HTTP and how to configure input.conf in that case? I tried to send my data to 'https://splunkserver.l7tech.com:8089/services/receivers/simple?host=XX.X.XX.XXX&index=main&source=www&sourcetype=wsdmxml', where I set www as a source in input.cong, but I didn't get anything in Splunk.

You need to write your own code to do this, using either modular inputs, or by sending to one of the REST API endpoints. You can find out more about this at http://docs.splunk.com/Documentation/Splunk/5.0.1/AdvancedDev/ModInputsIntro and http://docs.splunk.com/Documentation/Splunk/latest/RESTAPI/RESTinput#receivers.2Fsimple and http://dev.splunk.com/
