Abstract

A network device connected to a local network is configured using a module operating within a console connected to the local network. Once activated, the module obtains an unused network address. After obtaining the unused network address, the console waits for receipt of a request from the network device. Upon receipt of the request, the console forwards to the network device a response. The response includes the unused address along with subnet and gateway information for the console. The console then establishes a network connection to the network device and displays on a monitor for the console, an address value, a subnet mask value and a gateway value for the network device.

Claims

1. A computer implemented method used in configuration of a network device connected to a local network comprising the following steps performed by a module operating within a console connected to the local network:

(a) in response to activation of the module, obtaining an unused network address;

(b) upon receipt by the console of a request from the network device, forwarding to the network device a response which includes the unused address obtained in step (a) along with subnet and gateway information for the console;

(c) establishing a network connection to the network device; and

,

(d) displaying on a monitor for the console, an address value, a subnet mask value and a gateway value for the network device.

2. A computer implemented method as in claim 1 wherein step (a) comprises the following substeps:

(a.1) sending a ping request via the local network; and

,

(a.2) receiving a ping response via the local network.

3. A computer implemented method as in claim 1 wherein in step (b) the request is a BOOTP request and the response is a BOOTP response.

4. A computer implemented method as in claim 1 additionally comprising the following step:

(e) providing opportunity for a user via the console to accept, deny or modify the address value, the subnet mask value and the gateway value for the network device.

5. A computer implemented method as in claim 1 wherein step (d) includes launching a world wide web browser by which the address value, the subnet mask value and the gateway value are displayed.

6. A computer implemented method as in claim 5 wherein the module is a plug-in module of the world wide web browser.

7. A method for configuring a network device connected to a local network comprising the following steps:

(a) from a console located within the local network, interrogating active network devices to determine an unused network address;

(b) upon the console receiving a request from the network device, forwarding, by the console to the network device, a response which includes the unused address determined in step (a) along with subnet and gateway information for the console; and

,

(c) configuring of the network device using the unused address and the subnet and gateway information within the response forwarded in step (b).

8. A method as in claim 7 wherein step (a) comprises the following substeps:

(a.1) sending a ping request from the console out to the local network; and

,

(a.2) receiving a ping response by the console from the local network.

9. A method as in claim 7 wherein in step (b) the request is a BOOTP request and the response is a BOOTP response.

10. A method as in claim 7 additionally comprising the following steps:

(d) establishing a network connection between the console and the network device; and

,

(e) displaying on a monitor for the console, an address value, a subnet mask value and a gateway value for the network device.

11. A method as in claim 10 additionally comprising the following step:

(f) providing opportunity for a user via the console to accept, deny or modify the address value, the subnet mask value and the gateway value for the network device.

12. A method as in claim 10 wherein in step (e) the address value, the subnet mask value and the gateway value are displayed within a window of a world wide web net browser.

13. Storage media which stores a software module, the software module, when run on a console connected to a local network, performing a method used in configuration of a network device connected to the local network, the method comprising the following steps:

(a) in response to activation of the software module, obtaining an unused network address;

(b) upon receipt by the console of a request from the local network, forwarding to the local network, a response which includes the unused address found in step (a) along with subnet and gateway information for the console;

(c) establishing a network connection between the console and the network device; and

,

(d) displaying on a monitor for the console, an address value, a subnet mask value and a gateway value for the network device.

14. Storage media as in claim 13 wherein step (a) comprises the following substeps:

(a.1) sending a ping request via the local network; and

,

(a.2) receiving a ping response via the local network.

15. Storage media as in claim 13 wherein in step (b) the request is a BOOTP request and the response is a BOOTP response.

16. Storage media as in claim 13 wherein the method additionally comprises the following step:

(e) providing opportunity for a user via the console to accept, deny or modify the address value, the subnet mask value and the gateway value for the network device.

17. Storage media as in claim 13 wherein step (d) includes launching a world wide web browser by which the address value, the subnet mask value and the gateway value are displayed.

18. Storage media as in claim 17 wherein the software module is a plug-in module of the world wide web browser.
