How to list listening ports on Linux

Here is a command to see the listening ports on a Linux server : Apache, Bind, MySQL, and so on ...
It shows the ports numbers, the network adress (127.0.0.1), the processus which is listening and its PID.

echo "Open Ports:" ; netstat -anp | grep LISTEN | grep tcp | awk  '{print $4, "t", $7}' | more

Useful to see if a server is active, or to detect backdoors.
