ネットワークサーバ機群の安全な維持管理に関する研究(電気工学科)

Abstract

In these several years, it reached the situation we can easily get information through Internet on a worldwide scale. The various servers were installed even in our laboratory, and the information system environment that is adjusted to this kind of circumstance was improved for our laboratory students. Adjustment of the system was delicate, then it became the circumstance where often the server is unstable and/or suddenly had stopped. Our aim is simple that responsibility of the system manager to be little and confusion of plural manager to be little too. In this paper, we present the new system proposal for maintenance of server machine group through the VPN encoding communication method that can be controlled safely with remote manipulation. In supervision of the server machine group system, we use Mac OS X server supervisory tool and software "Webmin" to be able to manage basically with GUI. The result after the improvement was satisfactory, the supervision of the actual dynamic time of the server machine group became easier than before. It is future topic concerning the maintenance of the system that covers long term.
