title: Unknown Host error when attempting to connect to connect to Eclipse plugin repository
body: <p>I am running Ubuntu 9.10 and I'm attempting to install a plugin for Eclipse 3.5 from a repository that my company created. This worked in the past on this linux box and also works just fine on my laptop which has Windows XP installed.</p>
  
  <p>The exact error message I'm getting in Eclipse is:</p>
  
  <pre><code>Unknown Host: &lt;location of repository&gt;
  
  org.eclipse.equinox.internal.provisional.p2.core.ProvisionException
  </code></pre>
  
  <p>Any ideas what might be causing something that used to work not to work anymore?</p>
  
  <p>Thanks!</p>
  
  <p>EDIT: Also, it might be useful to know that I can connect to other eclipse plugin repositories fine; it seems that only my company's internal one is the problem.</p>
