title: Getting "Access from host not allowed, or unknown host" from Torque PBS Server using qstat command
body: <p>I'm trying to run command <code>qstat</code> but instead of getting the queue status I'm seeing this error:</p>
  
  <blockquote>
    <p>Cannot resolve default server host 'torqueserver' - check server_name
    file. qstat: cannot connect to server torqueserver (errno=15010)
    Access from host not allowed, or unknown host</p>
  </blockquote>
  
  <p>How can I solve that?</p>
