Uso del netstat per vedere i processi in ascolto (Tratto da Redhat)

Using netstat to see the listening processes

To see if a program or process is listening on a port, ready to accept a packet, use the netstat program.




netstat -tulnp


The arguments to the netstat program are listed below:


•t - Show TCP

•u - Show UDP

•l - Show only listening processes (netstat can show both listening and all established connections, i.e. as a client too)

•n - Do not resolve network IP address names or port numbers

•p - Show the process name that is listening on the port
