I have my own dedicated server, but I am not an expert. I do have help when it comes to looking after the server, but I would like to get a second opinion.
Recently I have been seeing these messages in /var/log/messages. Could someone tell what are these mean or should I be worried about it?
-ipt_unclean: Zero TCP ports 0/8080
