How to check the listening status of ports in CentOS 7?
You can use the following command to check the port listening status on CentOS 7:
- Use the netstat command:
sudo netstat -tuln
The above command will display all TCP and UDP ports currently listening, along with their corresponding program information.
- Utilize the ss command (which is faster and more powerful than netstat):
sudo ss -tuln
The command above will show all TCP and UDP ports that are actively listening, but it will not display the corresponding program information.
Please note that the above command needs to be run in a terminal with administrative privileges.
