Abstract:
1. A method of configuring a device across a network, wherein the device is a managed appliance for operatively communicating keyboard data, cursor control data, and video data between a plurality of computers connected to the network and a workstation connected to the network, the method comprising: (a) the workstation broadcasting a User Datagram Protocol (UDP) discover request message across the network; (b) in response to said UDP discover request message from the workstation, said device transmitting a UDP discover reply message, the discover reply message including at least a portion of an Internet Protocol (IP) configuration of the device, wherein the portion of the IP configuration includes a Media Access Control (MAC) address of the device, an IP address of the device, a subnet mask, and a gateway address of the device, wherein, if the device has not already been assigned an IP address, then the IP address sent in the UDP discover reply message is a default IP address, and wherein, if the device has not already been assigned a subnet mask, then the subnet mask sent in the UDP discover reply message is a default subnet mask, and wherein, if the device has not already been assigned a gateway address, then the gateway address sent in the UDP discover reply message is a default gateway address; (c) said workstation broadcasting a UDP test IP configuration message said UDP test IP configuration message including: the MAC address of the device, an IP address, a subnet mask, and a gateway address; and (d) upon receipt of said test IP configuration message, (e) upon receipt of the test IP configuration reply message from the device, the workstation sending a set IP configuration request message to the device, said set IP configuration request message including an IP address, a subnet mask, and a gateway address, and the MAC address of the device; and (f) in response to said set IP configuration request message, said device
