Window Scaling option reported ON even it is disabled in both server and client. #27

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Window Scaling option reported ON even it is disabled in both server and
client.

What steps will reproduce the problem?

1. Connect server and client in a 1GBit Switch
2. Start both servers (fakewww and web100)
3. Set the TCP Parameters of client and server as bellow.
    echo 1 > /proc/sys/net/ipv4/tcp_moderate_rcvbuf
    echo 4194304 > /proc/sys/net/core/wmem_max
    echo 4194304 > /proc/sys/net/core/rmem_max
    echo "4096 87380 4194304" > /proc/sys/net/ipv4/tcp_rmem
    echo "4096 16384 4194304" > /proc/sys/net/ipv4/tcp_wmem
    echo "1" > /proc/sys/net/ipv4/tcp_timestamps
    echo "1" > /proc/sys/net/ipv4/tcp_window_scaling
    echo "1" > /proc/sys/net/ipv4/tcp_sack
    echo "1" > /proc/sys/net/ipv4/tcp_ecn
4. Open the browser and open the NDT home page.
5. Start test by clicking Start button and check the results in statistics
window.

What is the expected output? What do you see instead?
Since the Window scaling is disabled in both server and client and is not
negotiated this option should be reported as OFF but it is reported as ON.

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.
