Getting Data In

Why did curl failed with error code 56?


I am trying to list existing HEC tokens with curl command as below:



curl -k -u admin:<admin_password> http://<splunk_enterprise_instance_ip>:8089/servicesNS/admin/splunk_httpinput/data/inputs/http -v



It retruned as below:



*   Trying
* Connected to ( port 8089 (#0)
* Server auth using Basic with user 'admin'
> GET /servicesNS/admin/splunk_httpinput/data/inputs/http HTTP/1.1
> Host: <splunk_enterprise_instance_ip>:8089
> Authorization: Basic YWRtaW46UGFzc3dvcmQwMTIzIQ==
> User-Agent: curl/7.61.1
> Accept: */*
* Recv failure: Connection reset by peer
* Closing connection 0
curl: (56) Recv failure: Connection reset by peer



From splunkd.log: 



01-09-2023 11:42:33.082 +0800 WARN  HttpListener [3447 HttpDedicatedIoThread-0] - Socket error from <splunk_enterprise_instance_ip>:38846 while idling: error:1407609C:SSL routines:SSL23_GET_CLIENT_HELLO:http request



It seems this is ownign to SSL.

However, I have disbaled SSL in both Splunk Enterprise Instance and HEC, from inputs.conf:



[dujas@centos8-1 local]$ cat /home/dujas/splunk/etc/apps/splunk_httpinput/local/inputs.conf
disabled = 0
enableSSL = 0



May I l know how I could make the http work?

I noticed the splunkdssl is enabled by default in server.conf, after disabling it in config file:


enableSplunkdSSL = False


Afterwards, I issued the same curl command and got output as below:

    <link href="/servicesNS/nobody/splunk_httpinput/data/inputs/http/http%3A%252F%252Ftest3" rel="alternate"/>

Token "test3" is the one I create via "http-event-collector" command, it could be loaded successfully, but for tokens created via GUI (before disabling splunkdssl), they are still failed to retrieve.

Any ideas why would that happen?
