title: Lighttpd - Cannot start, can't bind port, permission denied
body: <p>I have installed Lighttpd in parallel with Apache (using port 80). But starting lighttpd gives me an error </p>
  
  <pre><code>Starting lighttpd: 2013-04-05 15:56:17: (network.c.379) can't bind to port:  81 Permission denied 
  </code></pre>
  
  <p>Changes I made in lighttpd.conf:</p>
  
  <pre><code>server.port = 81
  server.use-ipv6 = "disable"
  </code></pre>
  
  <p>What am I missing here? I am using CentOS 6.3</p>
  
  <p><strong>netstat -ltp</strong> result:</p>
