Like so many other administrative tasks in Mac OS X, you have two ways to run the network services. The classic Unix way involves invoking the daemon on the command line, either manually through the Terminal or with a script.

When active, other computers can mount disks and folders on your filesystem via AFP. See the later section "File Sharing Services."
