How To Find Open Ports On Netstat

[Daniel@30]

Can anyone guide me on how to use netstat to check for open ports on my system?

To find open ports using `netstat` , run the following command:

- Linux/macOS : `sudo netstat -tuln` to list all listening TCP and UDP ports.
- Windows : `netstat -an | find "LISTENING"` to display open ports in the LISTENING state.

For specific ports, use `grep` (Linux/macOS) or `findstr` (Windows) with the desired port number.

To check for open ports using netstat, just open your command prompt or terminal and type netstat -an. This will list all the connections and listening ports on your system. Look for lines that say "LISTENING" under the "State" column, those are your open ports.

Use the `netstat -an` command to see all open ports on your system. Look for lines with "LISTENING" in the state column to identify active ports. For more details on a specific port, use `netstat -ano | findstr "<port number>"`.

For example, the command netstat -an | find "LISTEN" helps you filter and view only the ports that are currently listening for connections.
