-l: sistem üzerindeki dinlenen soket bilgilerini,
-p:Soket bilgileri için süreç numarası ve program ismi
-t, -u:t ile tcp , u ile udp protokollerine ait port bilgilerini,
-n: gösterilecek ip adres bilgileri için isim çözünürlüğü gerçekleşmez.
Ayrıca bu komutta işinize bi hayli yarayacaktır;
[oracle@eminyardim ~]$ netstat -tap
