One thing I did see different when looking at debug on the working platform (
Fedora Core 2 on a P3) is this:

# ./web100srv -ddd -m -l /var/log/web100/web
Reading config file /etc/ndt.conf to obtain options
ANL/Internet2 NDT ver 3.1.4
Variables file = /usr/local/ndt/web100_variables

Debug level set to 3
server ready on port 3001
web100_init() read 69 variables from file

Individual counts = [0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0]

Updated counter values Totalcnt = 2, Total Mismatch = 0, Total Bad Cables = 0
Individual counts = [0,0,0,0,0,0,2,0,0,0,0,0,0,0,0,0]

nothing in queue

However, when running on the newer system, I do not see much of this on the
newer P4 setup:

# /usr/local/sbin/web100srv -ddd -m -l /var/log/web100/web100srv.log
Reading config file /etc/ndt.conf to obtain options

What generates the information that is set to the tmp file? And any ideas why
it is not sending similar information? Is this something your patches are
designed to help with?


After patching the source, I am still seeing the same issue as before. Any further assistance and suggestions is much appreciated.
