body: <p>I have freshly installed apache-tomcat-7.0.62 on my server.
  When i start tomcat it start with no errors, but when i want to access it using browser it says page is unavailable. I have used following command to check whether tomcat is running correctly or not :-</p>
  
  <pre><code>     netstat -ntlp | grep LISTEN
  </code></pre>
  
  <p>and following is the output : - </p>
  
  <p>tcp        0      0 0.0.0.0:22              0.0.0.0:*              LISTEN      -<br>
