title: Can I use http tunnel to ping or traceroute through a proxy with firewall?
body: <p>I don't know if there is a way to ping a target outside my LAN proxy which accepts only Http requests through a squid proxy... I read somewhere that one way to deal with such problem is to use a http tunnel so that the proxy still sees the request as a Http request. Can I use this to ping,say, www.google.com which otherwise is giving the following error because the firewall is rejecting the request:</p>
  
  <pre><code>$ ping www.google.com
  ping: unknown host www.google.com
  </code></pre>
  
  <p>If so how is it done...? </p>
  
  <p>I have installed httptunnel.Any help in how to use it will be much appreciated.</p>
