Abstract

A system and method for enabling computers associated with a communications network to remotely locate each other and establish a master-slave relationship.

Claims

1. A system for enabling computers associated with a communications network to remotely locate each other and establish a master-slave relationship comprising:

a first computer having a first MAC address associated therewith;

a second computer having a second MAC address associated therewith and the first computer and second computer part of the communications network; and

a third computer, remotely situated from outside a subnet communication network including the first and second computers, having knowledge of the first MAC address and the second MAC address and sending a first message having the first MAC address and a unique identifier to the second computer and a second message having the second MAC and the unique identifier address to the first computer over the communications network;

wherein, subsequent to the first and second messages from the third computer, the first computer broadcasts a third message having the first MAC address and the unique identifier over the communications network and in response to the third message the second computer establishes a connected socket between the second computer and the first computer.

2. The system of claim 1 wherein the second computer responds with a fourth message having the second MAC address.

3. The system of claim 1 wherein the first computer sends a heartbeat message to the second computer.

4. The system of claim 3 wherein the second computer responds to the heartbeat message.

5. The system of claim 1 wherein the first computer sends a fifth message including a command to control the second computer.

6. The system of claim 1 wherein the second computer sends a sixth message including an indication of a change in IP address of the second computer.

7. The system of claim 1 wherein the first computer stops communicating with the second computer and disables the connected socket.

8. The system of claim 1 wherein the second MAC address is used to locate the second computer among the computers in the communications network and determine an IP address of the second computer.

9. The system of claim 1 wherein a user can break the master/slave relationship.

10. A method for enabling computers associated with a communications network to remotely locate each other and establish a master-slave relationship comprising:

broadcasting over the communications network by a remote computer a first message having a first MAC address associated with a first computer and a unique identifier;

broadcasting over the communications network by a remote computer a second message having a second MAC address associated with a second computer and the unique identifier;

broadcasting over the communications network a third message having the unique identifier and the second MAC address by the second computer;

establishing a connected socket by the first computer;

broadcasting over the communications network a fourth message having the first MAC address and the unique identifier by the first computer; and

establishing a second connected socket by the second computer.

11. The method of claim 10 further comprising sending a fifth message to the first computer through the connected socket.

12. A method for establishing a master-slave relationship among computer in a communications network comprising:

receiving from a remote computer a first MAC address associated with a master computer and a unique identifier;

subsequent to receiving the MAC address from the remote computer, broadcasting by a slave computer a first message having a second MAC address associated with the slave computer and the unique identifier;

receiving from the master computer a second message having the first MAC address and the unique identifier; and

establishing a connected socket over the communications network with the master computer.

13. The method of claim 12 further comprising sending a third message having a command for the first computer via the connected socked over the communications network.

14. The method of claim 12 wherein a user can break the master/slave relationship.
