title: Android: ping without /system/bin/ping
body: <p>On some devices, the binary <code>/system/bin/ping</code> seems to be removed. 
  When I connect the device by USB and type</p>
  
  <pre><code>adb shell ping
  </code></pre>
  
  <p>it says:</p>
  
  <pre><code>/system/bin/sh: ping: not found
  </code></pre>
  
  <p>Is it possible to still send ping requests from such devices? <br>
  What are other alternatives to find out if a server is reachable or if packets get lost?</p>
