title: Start tomcat webapp with root privileges
body: <p>I built a webapp that uses libpcap (via jpcap).</p>
  
  <p>In order to be able to get the network interfaces list or to bind to a network interface, the application (in this case a webaap that runs from tomcat server) must be running with root privileges.</p>
  
  <p>During development I simply ran Eclipse with root privileges (sudo eclipse) and my webapp worked just fine with Eclipse's local tomcat server.</p>
  
  <p>However, when I try to deploy my webapp to the "real" tomcat server, it isn't working.
  I Also tried to start the tomcat6 service with sudo and changed the TOMCAT6_USER definition (defined in /etc/init.d/tomcat6) from "tomcat6" to "root" but it made no difference.</p>
  
  <p>What should I do to make it work?</p>
