//So to scan you own PC and find open ports you can enter:
sudo netstat --tcp --udp --listening --program
//With this command you need to enter
sudo lsof +M -i4
//user, does help, but is not like those other tools, with fuser you can also kill the process which is listening on a given port.
sudo fuser -v 3143/tcp
