Network monitoring and visualisation tools 13th April 1993 netman@cs.curtin.edu.au Overview: We have developed a set of tools (3) which may be used to monitor and "display" network communications. Two of the tools provide a real-time picture of network communications, while the other provides retrospective packet analysis. These tools are designed to allow network managers to passively monitor a network and diagnose common network problems as quickly and efficiently as possible. The tools: Etherman is an X11 based tool which displays a representation of real-time Ethernet communications. Network data is promiscously received via a system "network tap" and summarised into useful statistics. These statistics are displayed in a graphical manner, as to allow both experienced network managers and newbies an insight as to how a network is being used. Etherman will also provide protocol summaries, usage statistics and postscript(tm) snapshots of network activity. Interman focusses on IP connectivity within a single segment. As with Etherman, this tool allows a real-time representation of network communications to be displayed. Interman employs the same methods of network data capture as Etherman, except only IP traffic is considered. Since IP is a network-level protocol, Interman will display multiple networks - both local and remote. Protocol summaries, usage statistics and postscript snapshots are also available. Packetman is a retrospective Ethernet packet analyser. This tool allows the capture and analysis of an Ethernet packet trace. Availability: At present, only binaries for SUN Sparc (SunOS 4.1.x) and DEC-mips (Ultrix 4.2a and above) are avaliable. Each tool must be run as root. ftp.cs.curtin.edu.au: ~ftp/pub/netman/[sun4c|dec-mips]/[etherman|interman|packetman].tar.Z You will also need: ~ftp/pub/netman/hershey-[sun4c|dec-mips].tar.Z -- Mike Schulze, Craig Farrell and George Benko.
