Student-accessible tools and techniques to aid in teaching network protocols

Abstract

This paper describes some of our experiences in using freely available network diagnostic aids as an adjunct to teaching the TCP/IP (Transmission Control Protocol/Internet Protocol) suite, and discusses our impressions of their suitability for teaching in both on-campus and off-campus modes. A particular focus is on the suitability of such tools for off-campus distance-mode learning, where several problems are present in the acquisition, installation, and use of such tools. Although there are many reviews of such tools from a network administration point of view, these invariably assume an expert level of knowledge, and as such are somewhat inaccessible to the student beginning in this area. Additionally, as they necessarily impact on the computing infrastructure and network security at the installed location, care must be taken in terms of advice given to students – either explicitly or implicitly. We briefly mention the ethical aspects of enlightening students to the possible subversive use of such software for spying, hacking and other activities
