Why is the REST API not answering ?

charlou — Mon, 12 Jan 2015 14:42:38 GMT

I'm trying, in vain, to get answers from the REST API as described here: http://dev.splunk.com/view/basic-tutorial/SP-CAAADQT

I tried a lot of things, among which:
$ curl -u cibrahim -k https://10.83.88.20:8089/servicesNS/cibrahim/search/
Enter host password for user 'cibrahim':
curl: (7) couldn't connect to host

$ curl -vk -u cibrahim https://10.83.88.20:8089/servicesNS/-/-/search/jobs/1421068924.6480
Enter host password for user 'cibrahim':
* About to connect() to 10.83.88.20 port 8089 (#0)
* Trying 10.83.88.20...
* Connexion terminée par expiration du délai d'attente
* couldn't connect to host
* Closing connection #0
curl: (7) couldn't connect to host

As you can see, I don't get any answer of any kind. Connection times out after a certain (timeout) amount of time.

I checked that my local instance of splunk (on my local server @ 10.83.88.20) is listening to port 8089:
# netstat -a | grep 8089
tcp 0 0 :8089 *: LISTEN

tcp 0 0 localhost:56809 localhost:8089 ESTABLISHED
tcp 0 0 localhost:8089 localhost:56809 ESTABLISHED

Any idea about what I could be missing in this (very) annoying hinderance ?

Thx in advance

Hi charlou

That seems to be correct. I have tried similar on one of our lab servers and it works as expected. I would suspect a firewall or similar is blocking you. It is good practice on any system to block ports that can be used to gain remote access so I suspect your architect has done that deliberately.

Here was my command and output.

bmunson$ curl -vku admin https://54.154.184.25:8089/servicesNS/admin/search/
Enter host password for user 'admin':
* Hostname was NOT found in DNS cache
*   Trying 54.154.184.25...
* Connected to 54.154.184.25 (54.154.184.25) port 8089 (#0)
* TLS 1.2 connection using TLS_RSA_WITH_AES_256_CBC_SHA
* Server certificate: SplunkServerDefaultCert
* Server certificate: SplunkCommonCA
* Server auth using Basic with user 'admin'

Re: Why is the REST API not answering ?

I am running into the same issue, however mine is a little different:

curl -vku kenneth.harford https://54.225.250.77:8089/services/apps/local
Enter host password for user 'kenneth.harford':
* Trying 54.225.250.77...
* Connected to 54.225.250.77 (127.0.0.1) port 8089 (#0)
* Server aborted the SSL handshake
* Closing connection 0
curl: (35) Server aborted the SSL handshake

Any ideas?
Thanks
Ken
