Note that this option can be time-consuming and will fail unless you have sufficient permissions. In this case the executable name is in at the bottom, on top is the component it called, and so forth until TCP/IP was reached. In some cases well-known executables host multiple independent components, and in these cases the sequence of components involved in creating the connection or listening port is displayed. b Displays the executable involved in creating each connection or listening port. a Displays all connections and listening ports. (Add -n to stop it trying to resolve hostnames, which will make it a lot faster.)
