TCP port for clients to connect over the network. How would you figure out
what port number it is listening on?
2）You have encountered a linux system that does not have any swap space
configured on it. How can you add swap space to the system while it runs?
What do you need to do to ensure that after a reboot the system retains the
newly-added swap space?
