Trouble Opening ports
Hello, I set up my home server and it is running Ubuntu Server 13.04, I need to open some ports the machine says the ports are allowed but when I use nmap and scan my server from my laptop it says they are closed how can i open them if they are closed?

What port you need to open, have you installed the corresponding service in the server.
Port 80 is open once we installed Apache server

Have you checked iptables ? Also, if this is for a service, check '/etc/services' and ensure there's a line there for your service with the corresponding port number, and if not, add one in.
