Ghost Multicasting :: essays research papers

cutaneous senses Multicasting allows one computer, the trace waiter, to download a fantasm image from the Server and hence redirects the image to other workstations, the Ghost Clients, through the use of TCP/IP settings over the network. The main advantage of Ghost Multicasting is that the downloading duration is extremely shortened as only one PC is downloading the image off the Server which dramatically reduces the risk of heavy network traffic.The only single out is that the PC chosen to be the Ghost Server has to involve enough free hard drive space to store the image which will then be redistributed.The Two Methods Of Ghost Multicasting.Manually Specified Ghost Multicast Using this method you have to manually pose unique IP addresses for the Client PCs by using and configuring the wattcp.cfg file located on each Clients boot record book.Automatically Specified Ghost Multicast This second method is by using Windows NT to automatically assign IP addresses to the Client PCs by the use of the Dynamic Host Configuration Protocol, or DHCP, included in Windows NT ver. 4.00.Manually Specified Ghost MulticastingSetting Up Ghost Server Disk1. Prepare a boot disk that includes and loads the necessary network drivers and maps the disk images directory from the network.2. Copy over the DOS Ghost Server program (dosghsrv.exe) to the same disk and add it to the autoexec.bat file. 3. Copy over the wattcp.cfg file to the disk and change the IP Address, Subnet Mask and Gateway according to network. (A supernumerary IP Address should be allocated for the Server PC)Setting Up Client Disks1. Prepare boot disks in the same order for the server boot disk but copy over ghost.exe instead of dosghsrv.exe.2. Edit the wattcp.cfg and add in a unique IP Address for each boot disk. (Usually IP Addresses would have been set up earlier for the specific use of identifying ghost client PCs) Ghosting Client PCs1. Load up the PC which will act as the Ghost Server with the Server B oot Disk and load dosghsrv.exe from the DOS command prompt.2. Type in a Session Name and select the Image data file from the disk images directory on the network.3. Start up Client PCs with the unique Boot Disks and load ghost.exe. From the Ghost Server, you should see the IP Addresses of the Clients appear in the window as each Client PC loads the Ghost program.4. Once every Client PCs IP Address can be seen in the Ghost Server window, you are able to select them all by clicking on Accept Clients.
