Abstract

A host computer sends the same pseudo local MAC address X to a plurality of client computers. The address X is set as a MAC address for receiving communication in each of the client computers. Then, installation information is sent together with the pseudo local MAC address X. Each client computer receives the installation information using the local MAC address X, and installs the information. By using the common pseudo local MAC address X for receiving communication, installation information can be simultaneously installed into the client computers.

Claims

1. A remote installation method for causing a first computer apparatus including a storage device storing installation information to install the installation information simultaneously to a plurality of second computer apparatuses each connected to the first computer apparatus via a communication network, the method comprising:

a first step of obtaining global MAC addresses which uniquely identify the respective second computer apparatuses, the obtained addresses being registered in the first computer apparatus;

a second step of sending a same pseudo local MAC address from the first computer apparatus to the second computer apparatuses having their respective global MAC addresses on the registration, the pseudo local MAC address being set as an MAC address for information reception by the second computer apparatuses;

a third step of sending the installation information, together with the pseudo local MAC address, from the first computer apparatus; and

a

a fourth step of causing the second computer apparatuses having set the pseudo local MAC address to simultaneously receive and install the installation information supplied together with the pseudo MAC address.

2. A remote installation system comprising a first computer apparatus and a plurality of second computer apparatuses connected to the first computer apparatus via a communication network, the second computer apparatuses performing simultaneous installing of common installation information supplied from the first computer apparatus by way of communication,

wherein the first computer apparatus comprises:

a storage medium storing the installation information;

MAC address obtaining means for obtaining global MAC addresses of the respective second computer apparatuses by way of communication;

MAC address registering means for registering the global MAC addresses obtained by the MAC address obtaining means;

MAC address sending means for causing the second computer apparatuses having their respective global MAC addresses registered on the MAC address registering means to be supplied with a common pseudo local MAC address to be set as a MAC address for information reception; and

installation information sending means for sending the installation information together with the pseudo local MAC address, and

wherein each of the second computer apparatuses comprises;

MAC address notifying means notifying to the first computer apparatus the global MAC address unique to said each of the second computer apparatus by way of communication;

MAC address setting means for receiving the pseudo local MAC address sent from the first computer apparatus and for setting the received pseudo local MAC address as a MAC address for information reception; and

installing means for receiving and installing the installation information sent from the first computer apparatus.

3. The remote installation system according to claim 2, wherein the MAC address obtaining means requests the MAC addresses from the second computer apparatuses and receives the unique global MAC addresses sent from the MAC address notifying means of the second computer apparatuses.

4. The remote installation system according to claim 2, wherein each of the second computer apparatuses further includes notifying means for notifying, to the first computer apparatus, installation report information on whether or not the installation information has been successfully installed, the installation report information being sent together with the global MAC address unique to the computer apparatus;

and

wherein the first computer apparatus further includes confirming means which, upon reception of the installation report information, checks the accompanying global MAC address against the global MAC addresses on the registration in the MAC address registering means, thereby identifying which of the second computer apparatuses has encountered an installation error.

5. A client computer apparatus connected via a communication network to a host computer apparatus for installing installation information from the host computer apparatus, the client computer apparatus comprising:

MAC address notifying means for notifying a global MAC address unique to the client computer apparatus to the host computer apparatus;

MAC address setting means for receiving a pseudo local MAC address sent from the host computer apparatus, the received pseudo local MAC address being set as an MAC address for information reception; and

installing means for receiving and installing the installation information that is sent from the host computer apparatus together with the pseudo local MAC address.

6. The client computer apparatus according to claim 5, further comprising notifying means for notifying, to the host computer apparatus, installation report information on whether or not the installation information has been successfully installed, the installation report information being sent together with the global MAC address unique to the client computer apparatus.

7. The client computer apparatus according to claim 5, further comprising printing means for printing on recording paper.

8. A host computer apparatus for installing same installation information into a plurality of client computer apparatuses connected via a communication network to the host computer apparatus, the host computer apparatus comprising:

a storage medium for storing the installation information;

MAC address obtaining means for obtaining global MAC addresses of the respective client computer apparatuses by way of communication;

MAC address registering means for registering the global MAC addresses obtained by the MAC address obtaining means;

MAC address sending means for causing the second computer apparatuses having their respective global MAC addresses registered on the MAC address registering means to be supplied with a common pseudo local MAC for setting as a MAC address for information reception; and

installation information sending means for sending the installation information together with the pseudo local MAC address.

9. The host computer apparatus according to claim 8, wherein the MAC address obtaining means requests the MAC addresses from the client computer apparatuses and receives the unique global MAC addresses sent from the MAC address notifying means of the client computer apparatuses.

10. The host computer apparatus according to claim 8, further comprising confirming means which, upon reception of information from the client computer apparatuses on whether or not the installation information has been successfully installed, checks the accompanying global MAC address against the global MAC addresses on the registration in the MAC address registering means, thereby identifying which of the client computer apparatuses has encountered an installation error.
