For the past few months I have been developing a web based configuration 
tester.  I have a globally visible copy at 
http://miranda.ctd.anl.gov:7123  This tool uses a Web100 enhanced kernel 
and a java applet originally written at ORNL to analyze end-to-end TCP flows.

The idea is to gather enough data from a single test to determine 1) the 
link type (Fast Ethernet, Ethernet, IEEE 802.11 wireless, or Cable/DSL 
modem); 2) the duplex setting (full or half); and 3) if a shared link in 
the path is congested.  It also looks for errors due to Duplex Mis-match 
and faulty hardware conditions.  The applet provides 'drill down' buttons 
to give the user as much or as little information as they want.  Finally 
there is a 'report trouble' button that will generate an email report.

So far this tester has received over 1000 hits from over 14 countries on 3 
continents.  I would be interested in hearing from this community on how 
accurate this tool is and what problems it fails to report.  Please give it 
a try and let me know what you think.
