A System for Providing A Ttraining Environment for Linux Networks using Virtual Environment Softwares

We have developed a system to provide a training environment where trainees can learn Linux network construction in a safe, easy, and relaxed manner using the environment software User-mode Linux. One trainee can construct networks consisting of virtual network components on one standalone PC. Therefore, it is not necessary that trainees connect this system to the Internet; trainers do not need to prepare a variety of physical network components, and trainees need not worry about system down or the negative influence with other networks caused by operation errors. Evaluation experiments using eleven students indicated that our system is effective for training in Linux network construction, though some problems remain with the user interfaces.
