+Check Listening Ports with netstat
|
|
|
+netstat is a command-line tool that can provide information about network connections.
|
|
|
+
|
|
|
+To list all TCP or UDP ports that are being listened on, including the services using the ports and the socket status use the following command:
|
|
|
+
|
|
|
+sudo netstat -tunlp
|
|
|
+
|
|
|
+The options used in this command have the following meaning:
|
|
|
+
|
|
|
+-t - Show TCP ports.
|
|
|
+-u - Show UDP ports.
|
|
|
+-n - Show numerical addresses instead of resolving hosts.
|
|
|
+-l - Show only listening ports.
|
|
|
+-p - Show the PID and name of the listener’s process. This information is shown only if you run the command as root or sudo user.
