title: Adding Host in Observium (Cannot Ping)
body: <p>I am using Observium v0.14.4 on CentOS 6.5. Everything is good to go with configuration and I am successfully accessing the software (I'm using HTTPS for web access). I am following the directions available for RHEL/CentOS [1].</p>
  
  <p>I am attempting to add a host ("beethoven") that is visible via ping and fping from the Observium machine ("mozart"):</p>
  
  <pre><code>[user@mozart observium]$ sudo fping beethoven.example.com
  beethoven.example.com is alive
  [user@mozart observium]$ sudo ping -c2 beethoven.example.com
  ... (this works) ...
  2 packets transmitted, 2 received, 0% packet loss, time 1001ms
  </code></pre>
  
  <p>However, when I attempt to add beethoven using <code>sudo ./add_device.php beethoven.example.com example v2c</code> I get:</p>
  
  <pre><code>Try to add beethoven.example.com:
  Could not ping beethoven.example.com.
  Devices skipped: 1.
  </code></pre>
  
  <p>Google and DDG don't reveal any helpful solutions. Thanks!</p>
