Synchronizing the LAN to NTP server is the most common route for most small installations. The NTP protocol is designed as a hierarchy to prevent large numbers (more than 10,000) of clients from accessing the same primary time sources. This hierarchy should be adhered to, and a large number of NTP clients should not be configured to hit a busy single NTP time server. Networks should be designed to minimize the number of computers that interact single busy NTP server. There are 2 different ways to set up an NTP server for a large number of clients:
With synergy, all the computers on your desktop form a single virtual screen. You use the mouse and keyboard of only one of the computers while you use all of the monitors on all of the computers. You tell synergy how many screens you have and their positions relative to one another. Synergy then detects when the mouse moves off the edge of a screen and jumps it instantly to the neighboring screen. The keyboard works normally on each screen; input goes to whichever screen has the cursor.
