Displaying all active Internet connections in Linux.
Question:
Displaying all active Internet connections in Linux.
Answer:
It may be necessary to display what Internet connections are active on your Linux box. For example, seeing if the Apache service is actively running and if running what network ports it's listening to. To do this run the below netstat command in the command line. netstat -natp If you have root privileges running the above command will give an output similar to the below example.
