New issue 30 by sekharnv73: Half Duplex mode not detected.
http://code.google.com/p/ndt/issues/detail?id=30

What steps will reproduce the problem?

1. Connect server and client in a 1GBit Switch
2. Start both servers (fakewww and web100)
3. Down the network interface eth0.
4. Set autoneg option of eth0 to off with ethtool.
5. Up the network interface eth0.
6. Set the network interface duplex mode as off and speed as 100Mbps with
ethtool.
7. Restart the network subsystem /etc/init.d/network restart.
8. Open the browser and open the NDT home page.
9. Start test by clicking Start button and check the results on main window
and statistics window.


What is the expected output? What do you see instead?
In Statistics window duplex mode should be displayed as half-duplex and
report duplex mismatch since server is in full duplex mode.
But duplex mode is displayed as full duplex and not reported duplex mismatch.

What version of the product are you using? On what operating system?
NDT server 3.6.1
Client : Linux (Fedora 8)

Please provide any additional information below.
