title: Cannot access Jenkins
body: <p>I have installed Jenkins on my Ubuntu 12.04 desktop machine using this guide:</p>
  
  <p><a href="https://wiki.jenkins-ci.org/display/JENKINS/Installing+Jenkins+on+Ubuntu" rel="noreferrer">https://wiki.jenkins-ci.org/display/JENKINS/Installing+Jenkins+on+Ubuntu</a></p>
  
  <p>I also needed to follow this guide:</p>
  
  <p><a href="http://aslamnajeebdeen.com/blog/how-to-fix-apache-could-not-reliably-determine-the-servers-fully-qualified-domain-name-using-127011-for-servername-error-on-ubuntu" rel="noreferrer">http://aslamnajeebdeen.com/blog/how-to-fix-apache-could-not-reliably-determine-the-servers-fully-qualified-domain-name-using-127011-for-servername-error-on-ubuntu</a></p>
  
  <p>From my other machine (mac laptop) I now try to access Jenkins through safari:</p>
  
  <pre><code>http://192.168.1.100/jenkins
  </code></pre>
  
  <p>where <code>192.168.1.100</code> is the ip address of my desktop machine but I get an Error 404. I have also tried:</p>
  
  <pre><code>http://jenkins
  </code></pre>
  
  <p>but nothing happens. What am I missing?</p>
  
  <p>The Jenkins service is running on my desktop PC:</p>
  
  <pre><code>service jenkins status
  ...
  Jenkins Continuous Integration Server is running with the pid 3713
  </code></pre>
  
  <p>And if I enter: <code>localhost:8080</code> in a browser on my desktop pc I get the jenkins web interface.</p>
  
  <p>PROBLEM SOLVED:
  I have followed this guide:</p>
  
  <p><a href="http://www.zzorn.net/2009/11/setting-up-hudson-on-port-80-on-debian.html" rel="noreferrer">http://www.zzorn.net/2009/11/setting-up-hudson-on-port-80-on-debian.html</a></p>
  
  <p>and it now works.</p>
