How can I check the status of listening ports in Linux?

To check the listening ports on a Linux system, you can use the following methods:

1. Use the netstat command:

netstat -tuln

This command will display all listening TCP and UDP ports, along with the corresponding process information.

1. Use the ‘ss’ command:

ss -tuln

Similar to netstat, the ss command can display all TCP and UDP ports that are currently listening, as well as related process information.

1. Utilize the lsof command:

lsof -i

This command will display all open network connections, including listening ports and related process information.

1. Use the nmap command:

nmap -sT -O localhost

nmap is a network scanning tool that scans all open TCP ports on the local host.

These commands will help you view the ports that are currently listening on a Linux system, along with the associated process information.
