I want to learn how to use two config files for synergy and call whichever one I have a desire to use at the moment ie: wireless ip addies connection or ethernet. I'm gonna have to look into that.

|
|
Where I am working there are an unknown number of XP machines, many unusable because that other OS is broken or malware. A few have real hardware problems. I managed to get a couple of models restored to "factory" (SP1!) and then updated to SP2,3 and today. I wanted to set up Clonezilla to make images to propagate throughout the building but the network has some 10 megabits/s boxes in the rack so I have to carry them to my lab to fix. I also enter data on the machines into a database. I find it easier to use SystemRescueCD rather than use Clonezilla (needs dhcp server and PXE booting) for this one-at-a-time approach. I cannot even bring all machines in at once because all the doors have different keys and I have no master key. I need to make an appointment... 
I have SystemRescueCD running on the "golden" system.
dhclient eth0 gets it an IP address
passwd sets a password for the root user
I start SystemRescueCD on the target system.
dhclient eth0 gets it an IP address.
ssh goldenmachineIPaddress dd if=/dev/sda |dd of=/dev/sda
That runs for an hour and overwrites the whole 40 gB of hard drive. It would be more efficient to use tar just to write files only, but I need to test the whole drive's surface anyway. This command runs a dd (disk duplicate) command on the golden machine and produces output from the ssh command on the target machine which is piped to a second dd command to write the local drive. The target machine then thinks it is the golden machine so I need to change its name and run the key update tool to use the correct COA code.
GNU/Linux is well accepted here. If I can generate enough interest, I could be installing GNU/Linux instead of preserving a dead OS next year. I was supposed to demonstrate GNU/Linux this week but events intervened. |
