I have previously configured and have the application operational. Upon
setting up Web100 and NDT on another system, I am having what appears to be
issues with the web100srv.

I am running kernel 2.6.12.5 with web100-2.5.4 web100_userland-1.5.4 and
NDT-3.1.4a. Current version of java is 1.4.2_09, and I have tried with both
the libpcap files that are provided by Fedora Core 4 and also compiling
libpcap-0.9.3.

I have used the following options when running the web100srv client.

./web100srv -a -m -l /var/log/web100/web100srv.log.

When running with -d I see the following:

# ./web100srv -d -m -l /var/log/web100/web100srv.log
Reading config file /etc/ndt.conf to obtain options
ANL/Internet2 NDT ver 3.1.4
Variables file = /usr/local/ndt/web100_variables
log file = /var/log/web100/web100srv.log
Debug level set to 1
server ready on port 3001
web100_init() read 69 variables from file

Upon starting a test I see the following:

Signal 17 received from process 6956
successfully locked '/tmp/view.string' for updating
sending '0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,,' to tmp file
listening for Inet connection on sock2, fd=3
server ports 32778 32779
listening for Inet connection on sock3, fd=5
Middlebox test, Port 32779 waiting for incoming connection
Set MSS to 536, Window size set to 16777216KB

I then receive an error that the server failed middlebox testing.

On the working system, I see much more output when the test is began...

Any help would be appreciated on this issue, and if more information is
needed, I can work on providing that as well.
