title: Cannot display xclock program on xserver client - Mobaxterm
body: <p>I am using Mobaxterm(free version) on a windows 7 desktop to connect to a SUSE 11 Enterprise server on AWS. I am trying to display the xclock program on my xtrem client but I get an error saying 'Error: Can't open display:'. I have used the following syntax to set the display on the server:</p>
  
  <pre><code>export DISPLAY=&lt;IP_addr&gt;:0.0
  </code></pre>
  
  <p>SUSE 11 does not come with xclock by default so I had to download it and install it. 
  The hosts file on my PC has the localhost entry commented out, I am not sure if that would make a difference. Any ideas on how to debug this? Thanks.</p>
