I tried it from ELk server using command:  
curl -H "content-type: application/json" -XPUT '[http://elk.example.net:5555](http://elk.example.net:5555)' -d '{  
"post\_date" : "2015-10-29T15:20:34","message" : "Nowshad\_amin" }' -v  
Response:

- Rebuilt URL to: [http://elk.example.net:5555/](http://elk.example.net:5555/)
- Hostname was NOT found in DNS cache
- Trying 172.32.0.157...

**Please take this into your consideration (For lumberjack I am using keys, but for http I am not using any keys and no authentication in my input file). I can send log using lumberjack but getting 401 response while sending log using http**

input {  
lumberjack {  
port =\> 5000  
type =\> "logs"  
ssl\_certificate =\> "/etc/pki/tls/certs/logstash-forwarder.crt"  
ssl\_key =\> "/etc/pki/tls/private/logstash-forwarder.key"  
}  
http {  
port =\> 5555  
}  
}

Any help will be highly appreciated

401 is an authorisation problem, not an ELK one.  
You need to sort out whatever is proxying these commands and wanting auth details.
