You can use the following command to view the ports that are currently listening:
- Use the netstat command:
netstat -tuln
This command will display all the TCP and UDP ports that the current system is listening on.
- Use the ss command:
ss -tuln
The “ss” command can also display information about the TCP and UDP ports currently being listened on.
