netstat not showing it makes sense, as it isn't really bound to any particular application on the machine itself. I suppose that netstat could be modified to take into account netfilter sockets ... nmap should show the ports though, as it's emulating various parts of a normal connection. In this particular case, nmap couldn't find the open ports because of a problem with the firewall script (meaning that the ports actually weren't open). t -- GPG : http://n12turbo.com/tarragon/public.key
