This chapter provides hacks that discuss setting up centralized services for allocating IP addresses to new clients via the Dynamic Host Configuration Protocol (DHCP), integrating these newly assigned IP addresses with an existing Domain Name Service (DNS), synchronizing the clocks on all of your systems via the Network Time Protocol (NTP), and even sharing a consistent set of X Window System fonts throughout your organization so that all your users can do their status reports using the same version of Computer Modern Ransom Note Oblique.
