Quit Fremont is a research prototype for discovering key network characteristics, such as hosts, gateways, and topology. Fremont uses an extensible set of Explorer Modules to discover information, based on a variety of different protocols and information sources, rather than a single network management protocol. This approach allows more complete and timely information to be discovered than, for example, using only one protocol, even one as capable as the Simple Network Management Protocol. The discovered information is time-stamped and recorded in a database (the Journal Server). The contents of this database are cross-correlated to form an increasingly complete network picture, to direct further discovery, and to highlight inconsistent information. The fremont login at bruno.cs.colorado.edu has been set up to provide two simple demos of Fremont, based on information discovered from the University of Colorado network. These demos show only some of Fremont's capabilities. Since the demos require logins (and, in the case of the X demo, X traffic) across the Internet, they exhibit poorer performance than you would get by just running a Fremont client locally and connecting to our Journal Server. If you have a SparcStation, a statically-linked X-windows executable is available by anonymous FTP from ftp.cs.colorado.edu, in pub/cs/distribs/fremont/xjsv.Z. Don't forget to set "type image" before retrieving this file. You can run this executable by doing uncompress xjsv.Z chmod +x xjsv xjsv -j bruno.cs.colorado.edu The Fremont source code is available by anonymous FTP, in pub/cs/distribs/fremont. If you are interested in learning more about Fremont, a paper describing its methodology is available by anonymous FTP from ftp.cs.colorado.edu, in pub/cs/techreports/schwartz/PostScript/Fremont.ps.Z (compressed PostScript) or pub/cs/techreports/schwartz/ASCII/Fremont.txt.Z (compressed ASCII). This paper is also included in the source code distribution.
