As a budget cutback, our school administrators asked us to shutdown all non-essential classroom computers at night to save electricity. I teach Linux in a classroom that has a Dell Poweredge 2850 Red Hat Enterprise Linux (RHEL5) server and 29 Dell Optiplex 745 student lab computers running Microsoft Windows XP SP3 as the host operating system and VMWare Server to provide virtual Linux machines for our classes. I researched on the Internet for the best solution to remotely shutdown the student lab computers at night. I was not able to find one post or how-to that completely answered my questions, but I was able to piece together a solution. In an effort to document this project and help others with similar needs, here are my notes on the project. Continue reading “How To Remotely Shutdown Windows XP Computers from a Linux Server“
The Information Technology Departments in the Business/Public Service Division at Greenville Technical College where I teach subscribe to the MSDN Academic Alliance which provides our students and faculty free download versions of select Microsoft products. Starting in September 2009, we were able to download either the 32-bit or 64-bit versions of Windows 7 Professional. Jumping on the opportunity to install Microsoft’s latest operating system and move from 32-bit to a 64-bit data path, the week of October 12, 2009 I began migrating from Windows XP Professional Service Pack 3 to the new Windows 7 Professional.

After 25 years of drying clothes and constant clogging with lint, it became apparent to Sharon and I that it was time to replace the old plastic accordion type dryer vent pipe with something more safe and durable. Our dryer had started overheating and turning itself off to keep from starting a fire, all due to a clogged vent pipe. A couple of years ago we paid a local home repair company about $500 to unclog the old pipe. They managed to punch holes in the old plastic pipe and could not clean out the whole length because of turns around corners. This time we decided to fix the problem properly. We hired a local general contractor to coordinate a week long renovation project. Continue reading “Dryer Vent Project – Week of February 11, 2008“
In a classroom or lab environment, it is easy to create non-typical situations and cause RHEL/CentOS Linux to behave badly. Such was the case over the past week for one of my personal lab servers. The server is stand alone and does not belong to a domain. It is not configured as a DNS or DHCP server at the present time. Continue reading “Slow Booting? Include RHEL/CentOS Linux hostname in /etc/hosts file”
