Virtual Network Computing and Secure Shell

Computing professionals of yesteryear worked in an environment that was concentric in nature. They all arrived at the same building at roughly the same time, all using the same tools in the same computing environment. The system administrator at such a site was responsible for a clearly defined body of knowledge and had a consistent platform on which to work. Times have changed. What was a centralized environment of time-shared terminals to a mainframe on a single operating system has evolved into a heterogeneous mixture of UNIX and Windows workstations. It's not just the computing environment that has changed; the physical environment has changed as well. The growth of a high-tech company may quickly surpass the available space resulting in the need for additional buildings that may reside on a campus or even across town. With the advent of powerful laptop computers, it is now possible for many hightech professionals to work from home increasing the system administrator's physical realm. How does today's system administrator face the challenges of maintaining and troubleshooting a company's heterogeneous and sprawling computing system from a central location? Enter Virtual Network Computing.
