title: Permission denied to bind to port when running Scala application via SBT
body: <p>I'm trying to run my Scala code with SBT, but get the error below. This happens both with SBT using the command line and with IntelliJ Idea.</p>
  
  <pre><code>    [error] (run-main) org.jboss.netty.channel.ChannelException:
      Failed to bind to: /127.0.0.1:80
      org.jboss.netty.channel.ChannelException: Failed to bind to: /127.0.0.1:80
      ....
      ....
      Caused by: java.net.SocketException: Permission denied
  </code></pre>
  
  <p>What do I configure to allow port access. This happens both when I try to run on my local Mac and on my remote Ubuntu server.</p>
  
  <p>Running sbt with "sudo sbt" fixes the problem, but this is not the solution. Where can I set permission to allow my Scala app to access port 80.</p>
