Most of the time, that command will work fine. After you hit Enter, the results may take a minute or two to fully display, so be patient. Here, for example, you can see that port is tied up by a process named picpick. PicPick is an image editor on our system, so we can assume the port is actually tied up by the process that regularly checks for updates to the app.

On the basis of the criteria like state, PID, protocol, we can also filter the list. Now this time, netstat is outdated. That's why it is replaced with ss and ip, but still, if we want to check the network connection, the netstat command will be one of the most used commands.

New netstat is described by ss command. Some features of netstat are absent in ss, but it is slightly faster compared to netstat, and can expose more TCP states.

We will run isof in the following form to determine the listening application on a particular port, as shown below:. In the above section, we have explained four ways in Linux operating system to check open ports. We also have learned about the processes which are bound upon particular ports.
