Check ports

To check which ports are open on a server


nmap <ip of the server>

To check on the other hand which ports a server is listening to (before the firewall) run on the server


netstat -tulpn

where -t (tcp) -u (udp) -l (show listening sockets only) -p (show process id) -n (show numerical addresses)
